3 Chairman's Letter

Climate action failure and infectious disease caused serious setbacks to global economy; strengthening corporate resilience is becoming a challenge. According to the World Economic Forum's (WEF) Global Risks Report 2021, "failure to respond to climate change" and "infectious disease" are the top two emerging risks in terms of likelihood of incidence and magnitude of impact. The impact of COVID-19 on the global economy in 2020 was profound and widespread, with significant price fluctuations in raw materials that affected both our revenue and profitability. Under the severe challenge, we leveraged on our production, supply, and sales platforms to maintain a stable inventory for optimal production, formulated relevant policies to strengthen our financial base, and improved our financial health. With the concerted efforts of our colleagues to elevate operational performance, we have improved our revenue and turned loss into profit in 2021. The continuation of the pandemic has brought the world into different degrees of isolation, making corporate governance more difficult and indirectly exposing the environment to greater impact. How enterprises across various industries to implement pandemic prevention and fulfill social responsibility has become crucial issues. In addition, in the first half of 2021, faced the worst drought in 56 years, and the government has announced the second stage of water restriction with a five-day supply and two-day cutoff policy. We have responded to the situation by working with the government to develop strategies to conserve water and improve water efficiency to minimize the impact on our operations. The impact of climate change will become more frequent in the future, and the impact of infectious disease is unlikely to ease in a short period of time. How to take this opportunity to reflect on and strengthen CPDC's resilience in responding to risks, to minimize the impact of these risks, and to identify more opportunities therefrom is a major challenge for CPDC’s path towards sustainable transformation.

Committed to achieving green petrochemical industry and reducing environmental footprint In the face of the increasingly challenging business environment, CPDC has continued to build a green petrochemical foundation, with the corporate vision of pursuing green ecology and creating a symbiotic living environment with the earth, environment, and society. The petrochemical industry has long been perceived as high energy and water consumption. CPDC has improved its production processes by enhancing efficiency and making good use of technology, to improve water efficiency and reduce costs through water conservation and recycling of process water in response to challenges brought by water shortage. CPDC places great importance on high-risk operations management and utilizes intelligent monitoring systems to monitor various data, not only to comply with regulatory requirements, but also to protect the health and safety of employees. Moreover, in line with the government's policy to promote high-value petrochemical products, we are gradually moving towards fine chemicals, product diversification, and high-value development. In addition to developing new products with market potential and continuously optimizing existing products, we are progressively entering high-end applications such as optics, electronics, and semiconductors. Furthermore, we have observed that many countries and enterprises have made net-zero carbon emission commitments in recent years. In this regard, CPDC has been promoting carbon reduction commitments that are in line with national policies and is working on more proactive carbon reduction objectives in response to

4 international energy saving and emission reduction initiatives. We are also committed to completing the remediation of the Anshun site within three years. The Anshun site is one of the few cases in the world where the site is contaminated with both dioxin and mercury. Although the contamination at the site is a historical consequence, as a member of the global village, we have taken concrete measures, including the addition of new treatment facilities, to improve the efficiency of the remediation. In the future, we hope through the sharing of experience in remediating the contaminated site will help the world to achieve more fruitful remediation results, which will bring beneficial and positive impacts on the environment of Taiwan and the world.

Overall improvement in ESG performance to attract sustainable funds With the changing environment, it has become an irreversible trend for enterprises to focus on environmental, social, and corporate governance (ESG), and ESG has also become an indicator of whether an enterprise has the prospects for growth. The emphasis on responsible investment by institutional investors reflects that enterprises' ESG performances will directly affect the ease or the cost of financing. Due to the petrochemical industry's high consumption of energy and water, ESG has come to be an important issue. Therefore, in addition to the gradual transformation to low carbon, CPDC will strive to make better corporate decisions to minimize operational risks. CPDC also requires all employees to be more prudent in evaluating investment risks, to fully assess the effectiveness of investments through budget control and procurement improvement measures, to continuously improve the effectiveness of corporate governance, and thereby attracting green and sustainable capital funding. In addition, we also communicate with stakeholders through various channels and demonstrate the results of our continued efforts to contribute to the promotion of social harmony and balanced development. We understand that only when all personnel understand the true meaning of ESG then everyone in the Company can work together towards this goal. Therefore, CPDC is committed to carry on enhancing our ESG performance and responding the United Nations Sustainable Development Goals to advancing to a sustainable enterprise.

5 From The President

Petrochemical business will continue to develop circular economy products CPDC is a manufacturer of caprolactam (CPL) and acrylonitrile (AN) , as well as a global leader in the production and operation technology. CPL is used to manufacture PA6 and develop high value- added PA6 products. In addition to assisting Taiwan's downstream industry in developing new diversified, special purpose, and high-value nylon products, the Company is also developing markets in the United States, Japan, and Europe. In the medium term, we aim to establish an integrated production base in China, introduce the application of AI technology, and build an intelligent management system. The petrochemical industry is characterized by high energy and water consumption. In order to development sustainably, we have long been investing in in-house research and development capability, introducing advanced technologies, and integrating heating and cooling energy uses to significantly reduce energy consumption and increase our competitiveness. We have started investing in the development of biomass plastics raw materials, biodegradable plastics, and recycled plastics to reduce the impact on the environment and society, and to improve the well-being of human life.

Land development business will strengthen the link to sustainable development CPDC's business philosophy is to maintain sustainable ecology and co-prosperity of the local community. We conduct thorough assessments and devise comprehensive plans for the urban area, traffic, and population impacts before any land development. The main building is planned as a green building to comply with the policy of green energy and urban development plan. In the design of the building, we also require designers to use natural ventilation and lighting along with the use of AIoT design. The smooth flow of internal traffic can reduce the energy use and environmental pollution. In the future, we will require partners to provide carbon footprints, obtain green building, and the smart building certifications to improve energy efficiency and align with international practices.

Reducing the impact of COVID-19 outbreak and bringing new opportunities to the Company In 2020, the world suffered from the outbreak of the pandemic, and CPDC was also greatly affected. In the early stage of the outbreak, the Company held pandemic emergency meetings to draw up strategies to maintain normal operation of production plants and to protect the health and safety of employees. In addition to the measures implemented at the head office, such as split team arrangements by floors and work from home, a second control room was set up at the each of the plants. The "COVID-19 Contingency Measures" were formulated to address the three stages of responses, the general pandemic prevention and protection, community infection in the area of operation, and confirmed cases in the plant. We also developed relevant measures for different target groups and situations, such as plant entry and exit management, plant health control, and contractor management, to avoid the risk of plant shutdown due to the spread of the pandemic. We also strengthen our information security protection and regularly promote information security on our internal websites. On the other hand, CPDC's main raw materials are part of textile products. With the advent of the post-pandemic era, we have developed products with characteristics such as bactericidal, anti- bacteria fiber, and filter material, gradually developing into specialized products to make positive contributions to the national pandemic prevention. In 2020, we have also started industry-academia

6 cooperation programs to continue to develop raw materials with anti-bacteria and bactericidal functions.

Continue moving towards a sustainable business CPDC continues to optimize its operations to respond to the United Nations Sustainable Development Goals (SDGs) and to explore potential business opportunities in niche SDGs. For example, in order to achieve the goal of the circular economy and reduce the impact of climate change, we build a high gravity system (HG) at our plants to collect elements from wastewater and recycle them into processed raw materials with the aim of reducing raw material costs. The generated water can be used to replenish the wash towers in other areas of the plants, reducing the amount of pure water used and the amount of wastewater treated. Meanwhile, the remediation of the polluted legacy site followed by the mandatory merge in the state-owned business era is integrated with the Company's public welfare activities to implement multi-faceted communication with the stakeholders. CPDC continues to optimize ESG performance and strives for recognition in capital markets. We proactively responded to the CDP climate change questionnaire and achieved a B- management grade in 2020. We also voluntarily participated in the S&P Global Corporate Sustainability Assessment and ranked 12th in the global chemical industry (PR 90) in 2020, with a total score of 77. CPDC was selected as a member of the 2021 S&P Global Sustainability Yearbook, the only chemical company in Taiwan to be included, and was also awarded the “Industry Mover” distinction in the global chemical industry. All of these are the result of the concerted efforts of our colleagues. Looking ahead, CPDC will keep implementing the four pillars of sustainable development strategies: Clever – smart-driven circular transformation, Prescience - planning for the future with sustainability governance, Dialogue – enhancement in the resilience of the value chain through communication, and Care – creation of social co-prosperity through care, and expand the eight major areas to deepen ESG performance in operational development and move towards sustainable enterprise.

Material Issues Analysis The CPDC CSR Report was compiled in accordance with the GRI sustainability reporting guidelines. The content of the report and level of disclosure were determined by its materiality. The higher the materiality level, the higher the risk. If mis-manages these risks, this may impact company operations, stakeholder decision-making, and seriously impact the environment or society. This year's list of potential material issues was based on the previous year's assessment results, taking into account the issues of concern for institutional investors' sustainability ratings, major global sustainability trends and issues, and material topics of benchmarking enterprises. After deciding on the list of issues, the materiality analysis was based on three aspects, "importance to company operations", "influencing factors and degrees on stakeholder evaluation and decision-making", and "external economic, environmental, and social impacts". Each topic was adjusted and considered in the materiality matrix. The result was then submitted to the Chairman for confirmation. The analytical process is set out below:

Global Outlook - Develop the Two Core Businesses of Petrochemical and Land Development. Expand into Overseas and the China Markets to Create New Engines for Growth CPDC is now aggressively expanding our two core businesses of Petrochemical and Land Development. The expansion of our overseas portfolio in China, Southeast Asia, and other regions will strengthen our long-term profitability and overall competitiveness.  Core Petrochemical Business CPDC is Taiwan's sole CPL producer, and one of the top 5 producers in the world. We are also one of the only two AN producers in Taiwan and are ranked among the global top 10. CPDC is very competitive in our core petrochemical business with production and operational expertise among the best in the world. At present, the petrochemical business aims to optimize the competitiveness of existing products and create a diversified market for new high-value products in the short term and establish an overseas integrated production base, introduce the application of AI technology, and build a smart management system in the long term. In addition, we are also actively promoting the strategy of extending the scope and depth of our petrochemical business to make it more sustainable and strengthen our competitiveness in the market: 1. Expansion of breadth: In recent years, the traditional petrochemical industry has been transforming, and CPDC has kept abreast with the trend to develop specialty chemicals and move towards higher-value products. In addition to the development of CPL derivative OPP by our own R&D team, CPDC has also mastered the catalyst and key technology, enabling CPDC the only OPP producer in Taiwan and the third largest producer in the world. In 2020, we continued to develop new products with special potential for OPP derivatives and optimize the OPP process. We also expanded our downstream operations, proactively created a greater range of high-value ester and special products, as well as continued to create value-added nylon products. We also cooperated across sectors to invest in green petrochemical raw materials research and actively built the foundation for green transformation. 2. Expansion of Depth: CPDC actively expands its petrochemical portfolio, developing the petrochemical project at Rudong in Jiangsu, China in 3 phases. In the first phase, the construction of the cyclohexanone plant and the PA6 plant have been completed and are expected to commence production in 2021. In the second phase, the CPL plant and the OPP plant have started their pre- construction operations. Future construction plans remain on track, with the aim to complete an integrated petrochemical base for CPL to improving our cost competitiveness. Also, we plan to continue to develop advanced production processes, lower the frequency of maintenances to improve production capacity. In addition to developing raw material and product shore tanks to increase production output and faster production flows, we are also progressively introducing AI technology, developing factory automation, moving towards realizing an unmanned factory. Concurrently, the command center is developing AI application technology and planning company's intelligent management systems, strengthening management performance, and establishing a base for smart petrochemical production.  Core Land Development Business

23 The main actions of the land development business are to proactively plan and revitalize domestic land assets, and concurrently pursue opportunities in overseas markets. The relevant measures are described as follows: 1. Develop the existing land assets in Taiwan and promote related development projects in phases and regions CPDC holds lands in the 5th A special area and the 6th special area of the Kaohsiung Multifunctional Commerce and Trade Park. The Company will deploy related development plans in accordance with the Kaohsiung City Government’s promotion of the “Asia New Bay Area” and the relocation of the 205th arsenal. Prior to this, we will continue with land revitalization. For the land in the Xiande Section of the of Kaohsiung City, which has been built for residential housing, the construction plan has been completed and the Kaohsiung City Council has agreed with the construction. It is expected to become a new target for Kaohsiung City’s next-generation residential housing1. 2. Development of overseas properties In response to new business opportunities arising from China's Belt and Road strategy and the rise of emerging markets in Southeast Asia, CPDC has set up subsidiaries in Myanmar, Vietnam, and India to actively explore large land areas with development potential, either by acquiring land for development or through strategic cooperation with existing but undeveloped projects. In Vietnam, Myanmar, or other Southeast Asian regions, CPDC will integrate organic farming to obtain petrochemical raw materials and establish petrochemical production bases (including agricultural and industrial areas) to drive residential and commercial development, with the ultimate goal of a sustainable, productive, living, and ecological smart city. 3. Sustainability considerations for land development In response to the government's policy of greening and energy conservation and urban development, we will not only enhance the development of large areas of land, but also uphold the concept of sustainable development and co-prosperity of the local community, with the goals of developing appropriate, safe, and smart building products through green buildings, carbon-absorbing civilization, and the integration of AIoT technology. In line with the international trend, we will also require partners to provide carbon footprint information, to attain green building and smart building certification, in an attempt to improve energy efficiency and to keep abreast with the international practices.

27 1.1.4 True Value Assessment Following the True Value Assessment of 2019, CPDC calculated the True Value in 2020 through 11 indicators based on the KPMG True Value methodology. According to the result, in 2020 CPDC integrated P&L was NTD 3,362,443 thousand, 2.90 times higher than EBITDA. This demonstrates our operational efforts in providing a positive impact on the overall environment and society at large. Comparing the Integrated P&L for the past two years, and looking at each item’s result of externality, the integrated P&L decreased in 2020 compared to the previous year mainly due to a drop in production and revenue as a result of the impact of the COVID-19 pandemic, as well as a reduction in overseas purchase amount of raw materials. However, this also resulted in a significant reduction in negative environmental factors such as GHG emissions, air pollution emissions, and water resources usage, and demonstrated our positive environmental management performance. (For the scope, description, and rate of change of each item, please refer to the True Value Assessment's Appendix)

1.2 Sustainable Development Overview 1.2.1 Framework of Sustainable Governance As a citizen of planet Earth, we embrace our corporate social responsibility and corporate resilience towards major risk as key goals in the transformation of CPDC into a green sustainable petrochemical enterprise. To imbue all CPDC employees with a common CSR DNA through the internalization of CSR and corporate sustainability factors, the CSR Committee was established in September 2013. The Chairman of CPDC serves as the chair of the CSR Committee while the President serves as the Secretary General. “Business Governance,” “Social Relations” and “Environmental Sustainability” were defined as the three key axes. The CSR Committee itself spans 22 departments and divisions. The Workplace Safety and Health Center together with the Corporate Relations Office of the Finance Division serve as the executive secretary for the promoting and running of Committee projects. The CPDC Board of Directors also successively formulates the Code of Corporate Social Responsibility and amends the CPDC Board of Directors Charter to elevate CSR promotion an explicit part of the Board's responsibilities. In addition, the CSR Committee is required to report to the Board at the end of each year on the results of the current year's implementation and to submit an

28 implementation plan for the following year. In order to normalize the operation of the CSR Committee and clarify the duties and responsibilities, and assessment methods, a draft of the CPDC Sustainable Development Committee Charter has been formulated in accordance with the Code, which will serve as a guideline for the future operation of the Committee and incorporate the Committee structure into the corporate philosophy.

1.2.2 Sustainable Development Strategies and Objectives Following the passage of the Paris Agreement and the establishment of the United Nations Sustainable Development Goals in 2015, corporate values and responsibilities have expanded from a simple focus on the economic performance to the harmonization of the economic, social, and environmental aspects. The pursuit of economic performance by businesses is only meaningful if the environment and society are also sustainable and not starved for resources. With the rise of sustainability and climate risks, CPDC is also responding to the trend. In 2020, CPDC comprehensively updated its sustainable development strategy with the vision of "striving for green and ecological development, coexisting with the environment and society", proposing the “2025 Sustainable Development Goals” and the “2030 Sustainable Development Vision”. The “Four Pillars of Sustainable Development and Eight Aspects in Sustainability Development of CPDC” incorporating the 7 UN SDGs were also formulated to serve as the guidelines for our sustainable corporate development. In 2021, we will extend specific goals and action plans based on our sustainability strategy to achieve our sustainability goals and visions.

38 Current Industry Situation and Competition Raw materials and sources Propene (CPC Taiwan) Ammonia anhydrous (100% imported) Current Industry Situation In Taiwan, there are only two AN suppliers: CPDC and Formosa Plastics Corporation (Formosa Plastics). The Company has already expanded production capacity in 2010, 2011 and 2019, and the production capacity this year was 230,000 metric tons. Although the production capacity of Formosa Plastics was 280,000 metric tons, for the most part of its AN output is for internal use to produce ABS and AF products. In 2020, the total AN demand in Taiwan was about 460,000 metric tons/year, which was close to that in 2019. Unfavorable market conditions 1.AF: 2021 Annual AF Demand estimates are flat or slightly increased due to the recovery AN of the global economy. However, Polyester (polyester fiber) continues to be replaced by a small portion, which will slightly affect AN production and price stability. 2.China continues to expand its new capacity, causing the balance of supply and demand in AN industry and the impact on prices. 3.Continental conservation policy (such as tariff protection, or the inclusion of AN as a processing ban) has also had an impact on the operations of AN Asian producer, and China- US trade conflicts have also affected the mainland's demand. 4.China has reduced VAT to 13% since April 2019, and there are no tariff barriers to the export of competing factories in the future, and competition for export has intensified.

CPDC response Develop NBR (Latex) and AM markets which enjoy higher demand growth rates and explore other regional sales area such as south India and the Middle East to reduce the dependence on the Chinese market. These efforts are starting to show positive effects.

Raw materials and sources Benzene (CPC Taiwan, partially imported) Phenol (Domestic purchase and foreign imports) Cyclohexanone (100% imported) Ammonia anhydrous (100% imported) Current Industry Situation The Company is the only CPL supplier in Taiwan. The CPL capacity in 2020 was 400,000 metric tons, and production volume in 2020 of 173,000 metric tons, full supply to Taiwan without export, with domestic market share of 43%. In 2020, with downstream production CPL of textiles and polymerization capacity increased in China and the COVID-19 causing the demand decline around the globe, it is a difficult competitive environment for Taiwanese suppliers. In Taiwan, CPL consumption during 2020 decreased by 22% versus 2019, with apparent demand at about 350,000 metric tons/year. As the growth in the supply of CPL in mainland China decreased in 2020, the production of the CPL industry increased. In 2021, it is estimated that CPL demand in Asia will rebound as the pandemic is under control, but there still will be a large amount of active investment in new CPL production capacity. Due to the absence of a significant increase in demand in the Asia CPL market, the CPL business will continue facing the stringent challenge.

39 Unfavorable market conditions 1.CPL capability in China expanded extensively, and supply was higher than demand in 2013. As CPL suppliers were competing for market share, price competition and profit reduction has occurred. 2.After PTA capability expansion in Asia in recent years, excessive polyester has substituted for nylon thread at a lower price point and higher market share. This affects the development of nylon thread in the general textile market. CPDC response 1.Focus on the top-down supply chain environment and changes in the market situation, acquired the Douliu nylon chips plant that can produce 80,000 tons/year, increase downstream customers and differentiation, flexibly adjust sales strategies and support downstream industries to increase operational performance, and face competition together. 2. Reinforce cultivation of engineering plastics and film markets to reduce the risk of selling products to a single market - nylon textile market. Increase the flexibility of sales adjustments with the company's development and production of functional nylon chips.

Raw materials and sources Phenol (Domestic purchase and foreign imports) Ammonia anhydrous (100% imported) Current Industry Situation Nylon chip production in Taiwan decreased in 2016~2020, due to COVID-19 and decreasing sales in China caused by oversupply in China Nylon chip production. As supply capacity remains higher than demand, the amount of export is large. With the increasing self-sufficiency of China’s production capacity, Taiwan’s exports to China have been gradually reducing; sales in other regions increased year by year, gradually shifting its dependence on the China market. The Company produces nylon chips with CPL through vertical integration for downstream suppliers to produce nylon threads, engineering plastics, and nylon films. By producing and selling nylon chips, the Company maintains a link to the nylon market. To cope with segmentation and heterogeneous growth of PA6 downstream nylon products, we continuously adjust the structure of our downstream customers.

Unfavorable market conditions Nearly 55% of the downstream industries of nylon chips in Taiwan concentrate in clothing fibers with the export market focusing on China. Therefore, the concentration effect of a single industry and a single market is significant. CPDC response After the acquisition and capacity expansion of polymerization equipment, most Taiwan suppliers avoided price-driven competition with China, increased export to niche high- quality markets in Asia, Southeast Asia, and India. The Company also emphasizes material supply contracts with domestic Taiwanese customers to strengthen sales and is committed to the development of the engineering plastics, film, and fishing net wire market, which is a success.

Raw materials and sources OPP Cyclohexanone (internal production with a part supplied by Taiwan Prosperity Chemical Corp)

40 Current Industry Situation The Company in 2016 completed a pilot plant, and is the only supplier of OPP domestically, and is the 3rd largest producer in the world. This product is a vertically integrated, specialty product line, and uses Cyclohexanone as its main raw material. The R&D center developed catalytic converters, production design, and completed the plant construction. The main end product for this product line is flame retardant, optical materials, and antiseptic/sterilization purposes. Through the production and sales of OPP, we intend to further develop our operations in specialty chemicals, expanding OPP derivative products for different end markets. Through the differentiation of downstream products and growth potential, we continue to adjust our client mix, and further develop CPDC's entry into the specialty chemical market.

Unfavorable market conditions The main competitor has a market share of over 50% and enjoys preferential tax rates in major demand markets, which is unfavorable for Taiwan's special chemical products. CPDC response To avoid price-driven competition with China, the CPDC will develop OPP derivatives to enhance the market share for the Asia region and create new business market areas and customers, for example the Europe and the United States.

41 Chapter 2 Forward-Looking Governance 2.1 Corporate Governance Steady corporate governance is the foundation of sustainable business management. The implementation of the corporate governance system strengthens the role of the Board of Directors and boosts the effectiveness of the functional committees. The Company strives to enhance the transparency of information disclosure, protect the rights and interests of stakeholders and fulfill our corporate social responsibility. Every effort is made to prevent corruption and inefficiency by ensuring that business risks can be properly addressed and reduced through our internal control and audit systems. CPDC responds to the trust of shareholders and stakeholders through the above measures. In 2020, CPDC received a ranking of 21% to 35% in the Corporate Governance Assessment. In addition, CPDC also actively participates in and responds to the S&P Global Corporate Sustainability Assessment (CSA). Through governance-related questionnaires, the international governance trends and the expectations of institutional investors are taken as the direction of improving corporate governance.

Corporate Governance Best Practice Principles

Responsibilities and Performances of Corporate Governance

2.1.1 Framework of Governance Role of the Board of Directors CPDC formulated the "Rules for Election of Directors" to set out the nomination and voting process for directors. The rules ensure that the process for the selection of directors is open and transparent. Moreover, in response to the international trend, CPDC established “CPDC Corporate Governance Best Practice Principles” in which “CPDC Implementation of the Diversity Policy for Board of Directors” explicitly called for greater diversity in the composition of the Board of Directors by taking gender, age, nationality, cultural background, professional background, professional skill and industry knowledge into account.

CPDC Annual Report

Functional Committees The Remuneration Committee and Audit Committee were established by CPDC in 2011 and 2013 respectively to improve the efficiency of the Board of Directors, protect shareholder rights, and improve the transparency of corporate governance. The committees provide a check and balance mechanism by strengthening the role and function of the independent directors. In this way, the committees can make decisions in an independent and objective manner. The roles and activities of the functional committees in 2020 are summarized below:

2.1.2 Risk Management Operating Mechanism of Risk Management CPDC faces risks that are more diversified, more complex than before along with globalization and climate change. It has become a key issue to comprehensively capture and manage the risks that have a significant impact on the operation and profitability of the Company in a systematic manner. CPDC's Board of Directors is fully responsible for overseeing the Company's risk management structure, controlling the Company's risk management policies and reporting its operations on a regular basis. To reduce the impact of risk events on the Company's operation, CPDC established a systematic risk response policy and process through a PDCA process in accordance with the materiality principle and ISO 31000 Enterprise Risk Management framework by the end of 2019. CPDC identified a total of 26 risk issues in 5 major aspects, and invited all department heads to discuss risk response and management actions. In addition, we integrated the risk management plans of each department in 2020 and moved toward the goal of establishing a risk management system. In the future, we hope to establish a dedicated "Risk Management Committee" to comprehensively evaluate and manage material risks that impact the Company's operations and profitability with a systematic approach to risk. In addition, CPDC pays more attention to climate risk. Following the four major disclosure frameworks of Task Force on Climate-related Financial Disclosures (TCFD), the Company identified and managed climate change transition risks and physical risks, and conducted financial impact assessments for high-risk factors. In order to protect the privacy of customers, CPDC also implements the provisions of the Personal Information Protection Act, which stipulates that all information related to business information, transaction details and other information that involves the privacy of customers shall be compiled and filed by dedicated personnel, and that access to such information shall be approved and authorized in an attempt to implement the management of customers' personal information and strive to reduce the risk of data leakage to comply with the most basic legal requirements. (Please refer to Chapter 3 of the report for the climate risk)

Emerging Risk Management and Response In addition to the high-risk topics, CPDC is also aware of new emerging risk items, such as Intellectual property protection, infectious diseases and their operational impact, supply chain risks, climate change and information security risks. Below are explanations for these risks.

Emerging Risk Response and Management Management Direction and Emerging Risks Importance and Impact Response CPDC adopts advance deployment.  CPDC is located in the middle and upper We provide sufficient anti-epidemic stream of the industrial chain. The epidemic supplies, implement personnel of diseases will cause economic recession segregation and working from home and weak downstream demand. Thus, systems, promote maintaining social Infectious purchasing demand will decrease and distance, and regularly investigate Diseases CPDC's revenue will be affected employees’ contact and travel  Strong infectious power of diseases will history. In addition, we actively cause mass infection in CPDC’s plants. If promote digitalization, so that when many employees are infected, production the epidemic is severe, the meeting and operation will be forced to suspend can still proceed smoothly. 52 Management Direction and Emerging Risks Importance and Impact Response  As for CPDC’s purchase amount, the raw materials and equipment costs account for 89.54% of the operating cost. The stable supply of petrochemical raw materials is the key factor for CPDC's sustainable operation  According to the results of supply chain risk Supply Chain Refer to Ch4.1 Sustainable Supply assessment, more than 70% of suppliers Risks Chain Management lack environmental protection actions and sustainable governance and disclosure. Suppliers' lack of ESG awareness and establishment of relevant response actions will make CPDC expose in the risk of supply chain disruption  CPDC is classified as a high carbon emission and high water consumption industry, and climate change exposes CPDC to transformation and physical risks. Based on the assessment of potential impact, potential vulnerability, and risk likelihood, the top three climate risks for CPDC are identified as "increasing GHG emissions", "drought due to changes in rainfall patterns", and "green product substitution", and the financial impact assessment is conducted under the assumption of "temperature rise not exceeding 2℃".  “Increasing GHG emissions" may require CPDC to purchase additional carbon credits Refer to Ch3.2 Climate Change Climate Change or actively invest in low-carbon technology Response transformation (accounting for 60% of the total investment in low-carbon technology transformation), both of which increase operating costs.  “Drought due to changes in rainfall patterns" may cause CPDC to face 3 major drought events, and face 4 weeks of level 2 water restrictions (20% reduction in supply) and 10 weeks of level 3 water restrictions (supply 5 days, no water for 2 days). This would result in a 45% reduction at the Toufen plant, a 50% reduction at the Dashe plant and a 25% reduction at the Hsiaokang Plant, with the Toufen plant accounting for 43% of the total revenue loss. CPDC has purchased a cloud  A continuous increase in the number and sandbox information security frequency of cyber attacks, the substantial protection system to protect Information growth in ransomware viruses and important information hosts and Security Risk continuous involvement in attack data, and to ensure uninterrupted techniques lead to a drastic increase in the operations of the information risk of information security. backbone.

53 Information Security Risk CPDC has set up an Information Office under the Administrative Resources Department, which is divided into information system and network equipment management groups, and established an internal information security management strategy. It regularly provides employees with information security information on the Company's internal website, such as common email scams, etc. In 2020, when CPC, Formosa Plastics Group and other industry peers encountered cyber attacks, we also immediately announced relevant cautions and called on colleagues to change their passwords regularly and to contact the Information Office as soon as possible if there are concerns regarding suspected information security incidents. In recent years, due to the rapid development of digital automation technology and AI technology, continuous increase in the number and frequency of cyberattacks, substantial growth in ransomware viruses and continuous involvement in attack techniques, in order to protect the Company's important information service operations from being affected, CPDC has purchased a cloud sandbox information security protection system to protect important information hosts and data, and to ensure uninterrupted operations of information backbone. In view of the continuous development of network technology, SDWAN technology has become mature, and network equipment manufacturers have launched new architecture network equipment in line with the software-defined network. CPDC will continue to introduce the latest network equipment and management models in order to strengthen its network management capabilities, reduce network dedicated line costs, and flexibly utilize network equipment to build network services for flexible applications. In response to the outbreak of COVID-19 in 2020 that affected employees' mobility and communication, CPDC implemented split working at the beginning of the outbreak, with some employees working from home and isolated from home when traveling abroad and returning home. The SSLVPN license and the new video conferencing system have been added to the existing information architecture to meet the needs of remote-working colleagues.

Other financial disclosures encompass investment subsidiaries listed in the CPDC consolidated financial report

Remuneration CPDC's Chief Executive Officer (CEO) is concurrently served by the Chairman of the Board of Directors. The remuneration of the Chairman is evaluated by the Board of Directors considering both internal and external factors, while the CEO position is not remunerated. The remuneration (including salaries, allowances, and bonuses) of the President and Vice President of the Company is determined in accordance with Article 29 of the Company Act with reference to market conditions, qualifications, responsibilities, experience and risks, etc. We established a Remuneration Committee in September 2011. The procedures for determining remuneration are based on the overall operating performance of the Company, the future operating risks and development trends of the industry, as well as the individual's performance achievement rate and contribution to the Company's performance in order to provide reasonable compensation. The relevant performance evaluation and the reasonableness of the remuneration are reviewed by the Remuneration Committee and the Board of Directors. The remuneration system is reviewed from time to time in accordance with the actual operating conditions and relevant laws and regulations to strike a balance between sustainable operation and risk control of the Company. According to the Company's Rules for Distributing Bonus and Rewards and taking into account the performance of each business unit and individual, after being approved by the responsible supervisor, reasonable compensation will be given to the employees. The Company regularly participates in international salary surveys to calibrate salary levels and provide competitive salaries, and makes salary adjustments based on the Company's operations, price indices, economic growth rates, and individual performance. According to the “Working Guidelines for Distribution of Employee’s Compensation”, if an appointed manager (CEO, President, Vice President, Assistant Vice President, factory chief, manager) is involved in corruption, waste or intending profit for others, and such situation is deemed serious and drastically impacts the Company's interests, he/she shall not receive any employee compensation. Moreover, his/her bonuses issued in the past shall be recovered. In recent years, CPDC provides immediate rewards to outstanding colleagues. We mainly adopt cash payment as our incentive method and emphasize a quick and highly rewarding compensation system. Therefore, there is no deferred payment, and no stock has been used as a reward in recent years.

Major Investment Investment is a key element of sustainable corporate development. Environmental changes in the petrochemical industry led to CPDC recognizing that precise investment, research and

55 development form the cornerstones for business performance and sustainability. As the CPDC vision suggests, we value investment performance but also care and respect for humans and the environment. Both domestic and overseas major investments strictly abide by local laws and regulations related to labor, human rights and environmental protection, so as to avoid illegal risks and implement social responsibilities to the residents. If collaborative suppliers and contractors in investment cases need to sign a contract, they shall sign the Supplier CSR Commitment Letter and commit to abide by the United Nations Guiding Principles on Business and Human Rights and other international standards. We expect and require all of our suppliers to accept , implement and support a set of ESG standards in the hope that that our partners value ESG together with us. There was no child labor, forced labor, or violation of international conventions on human rights from any major investments made by CPDC in 2020. Our investments also delivered a range of benefits such as creating local employment opportunities, attracted new inhabitants, stimulated the local business economy and consumption, and boosted government tax revenues.

The Management and Domestic Land Assets CPDC owns land with significant commercial development potential located in the Kaohsiung Multifunctional Commerce and Trade Park, including 3.9 hectares of land zoned for commercial/residential use in Special Zone 6, and 12 hectares of land zoned for commercial use in Special Zone 5A. Land development has gradually grown into CPDC's second core business in recent years. Our Land Development Department is responsible for land acquisition, planning and development, the management of the commercial real estate, property management, as well as the construction and sale of residential developments. Revitalization strategy of land assets are also developed. CPDC's production and business (Plant) sites in Kaohsiung are managed by the Dashe Plant and the Hsiaokang Plant. The non-business sites are developed in the direction of construction and tender.

We adhere strictly to all regulations relating to the Company Act, Securities and Exchange Act, Business Entity Accounting Act, Political Donation Act, Anti-Corruption Act, Public Procurement Act, Act on Recusal of Public Servants Due to Conflicts of Interest, public listing or other business activities. CPDC established the “Company Business Integrity Code”, “Standards of Ethical Conduct”, “CPDC Procedures for Ethical Management and Guidelines for Conduct” and “CPDC Standards and Solutions of Ethical Conduct for Personnel at All Levels”, governing dishonest and unethical behavior, bribery, corruption, unfair competition, confidentiality, conflict of interest, political donations, and strengthening of ethical business management training. In addition to disclosing the CPDC ethical and business integrity philosophy and policy through internal regulations, annual reports, the corporate website and other promotional materials, product launch conferences, institutional investor conference and other external activities are also used to help suppliers/contractors, customers, other agencies and personnel understand the ethical management concept and rules. These serve as a guide for everyday business interactions at CPDC and the implementation of CSR.

Company Business Integrity Code

Procedures for Ethical Management and Guidelines for Conduct

Standards of Ethical Conduct

Employee Code of Conduct CPDC introduced the "Non-Disclosure Agreement" and "Employee Conduct Policy" to regulate fair trading, conflicts of interest, insider training, intellectual property rights, confidentiality and non- compete clauses. When new employees first report for duty, they are required to understand and sign two declarations stating that they will obey laws and regulations governing the protection of trade secrets. They also guarantee that they will not infringe on the intellectual property rights of other people or violate company rules. The signing of the declarations enhances the professional ethical standards of employees. Integrity is also introduced to their routine work and processes.

Employee Conduct Policy

Education and Training on Ethical Business Management Orientation training is organized by CPDC for new employees. Ethical business management is incorporated into the curriculum with internal and outside instructors invited to teach new employees. At the same time, the "Procedures for Ethical Management and Guidelines for Conduct" require CPDC to undergo at least one ethical business management education or training session every year. In 2020, internal and external education and training related to integrity management issues (including relevant courses on integrity management regulations compliance, prohibition on insider trading and internal control) were held for all operating locations (including Myanmar and Vietnam), with a total of 1,400 employees undertook 1,167 personnel hours of education and training. Education and training helped employees gain a full understanding of CPDC's ethical business management policy, preventive programs and the consequences of unethical behavior. No violation of integrity management and ethical behavior occurred in 2020.

Political Donation CPDC has rules that ban illegal political donations and for making political donations. Employees are banned from making direct or indirect donations to political parties, organizations engaged in political parties, or individuals. Political donations may not be used to secure business benefits or a competitive edge. No political donations were made by CPDC in 2020.

Whistleblower System and Protection CPDC has a "Whistleblower System" and "Whistleblower Incentive and Protection Measures" in place. Employees and outside personnel are encouraged to actively report any unethical or illegal behavior. If a stakeholder discovers that an employee is engaging in illegal or improper behavior that may impact the rights of other people or the company, or if they intend to exploit their position for improper gain, they may submit a complaint in writing, by phone or through e-mail stating who, where, when, what and how along with any supporting information to the Audit Office of the responsible unit. The Audit Office did not receive any complaints in 2020. CPDC and personnel assigned to handling complaints should investigate and report on the matter in a fair and impartial manner. The whistleblower should be protected against retribution or improper treatment. Confidentiality should be maintained throughout the entire process. Dedicated hotline: 02-8787-1003 Whistleblower Email: [email protected]. In addition, for investors, suppliers/contractors, customers, local residents and employees, the Stakeholder Area on the CPDC website provides dedicated contact with names, direct lines and email for making complaints or submitting feedback.

Comply with regulations and respond to domestic and international initiatives CPDC actively participates in and supports important standards or advocacy in Taiwan and internally. We have also joined petrochemical, business and trade-related associations to stay in touch with industry peers and stay on top of the latest trends. Through associations' suggestions and opinions on the current regulations and policies, CPDC is aware of risks and opportunities well so that we stay competitive. For domestic and external advocacy, CPDC actively supports the government's energy conservation and carbon reduction policy by participating in the Voluntary GHG Reduction Plan of the MOEA Industrial Development Bureau to promote the reduction of GHGs. For product safety and environmental risk control, in addition to continuing to promote domestic/overseas certification on quality and environmental management, CPDC also complies with the requirements of the EU Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) directive as well as other related domestic guidelines. In addition, for the re-zoning issue of the Dashe Petrochemical Industry Zone, CPDC and other petrochemical companies jointly established the "Dashe Industrial Area Sustainability Working Group" to continue communicating with the government, local elected representatives and nearby residents. Attention was drawn to the continuous and effective improvements to industrial safety and environmental protection throughout the Dashe Petrochemical Industrial Area when appropriate.

The data from the Taipei Office, Douliou Plant, Qiaotou Plant, and Anshun Site will be included later, depending on the completeness of the data.

3.1 Product Development Strategies 3.1.1 Smart Production CPDC began promoting the intelligent production program at the end of 2016. Through cross- departmental integration and systemic review, we promote intelligent production through five aspects, including automated inspection, intelligent control, real-time monitoring, smart transportation, and preventive maintenance, with Industry 4.0 as the direction and unmanned factories as the goal. CPDC's intelligent projects were implemented in two phases.

In line with the government's policy of promoting high value petrochemicals and investing in Taiwan to promote the prosperity of local industries and increase job opportunities, CPDC built the Qiaotou Plant in Kaohsiung and invested in a fine chemical plant in Miaoli in 2020. The construction cost of the Qiaotou Plant is approximately NTD450 million, with an estimated annual production capacity of 9,000 tons of engineering plastics. In the face of the increasingly challenging global market, after the addition of the Qiaotou Plant, CPDC will accelerate its own production lines and materials development to complete the planning of upstream and downstream integration of the industry. For the direction of circular economy materials, we have achieved the concept of corporate sustainability. By 2020, we have developed a series of recycled industrial plastic products using ABS, PP, and PA6 recycled materials, with each product containing more than 20% recycled materials. At the same time, we have also developed high-flowing material specifications, which help to reduce customers' processing time and efficiently lower energy consumption. In the future, we will actively research and develop and move into high value-added fields. We plan to invest NTD 6 billion in the construction of the fine chemical plants by phases, with future production items, including OPP downstream optical derivatives, glycol series monomers, and multi-purpose nylon, which will help CPDC enter the high-end optical application market, key additives for coatings, etc. It can be widely applied to co-polyester products in combination with the Company's own polymerization technology to expand to a richer and more diversified downstream product line, demonstrating the results of vertical integration of CPL supply chain and continuously accumulating operational capacity. Approximately NTD 442 million was invested by CPDC in R&D-related activities (including costs and capital expenditure) in 2020. 9 new patents were also obtained bringing our effective patent portfolio to 187 patents. Our R&D capabilities are therefore continuing to increase and gather steam. CPDC began introducing the Taiwan Intellectual Property Management System (TIPS) in 2010, which is supported by the MOEA Industrial Development Bureau, and was TIPS-certified, so as to create, maintain and use the Company's intellectual property to make the greatest benefits to the Company. The president is responsible for the performance of the Company's intellectual property management, and the supervisors at all levels have the same responsibility for the units they lead. They require personnel to work together and aim to increase the number of annual internal patent examinations to more than 5 cases, while continuing to grow, progress, and innovate.

3.1.3 Use of Raw Materials CPDC’s use of raw materials mainly comes from the materials for producing main products and services. Due to industrial characteristics, the products are mainly delivered by tank trucks, and the recycling of product packaging materials is mainly wood pallets. Since wood pallets have a service life, those that cannot be recycled are disposed of by customers. The annual recycling ratio is maintained at around 70%.

3.2 Climate Change Response Climate change issues have continued to heat up at the international and regional levels over the years. The passage of the Paris Agreement at the end of 2015 made climate change an issue that national governments and top international enterprises must now face. Active management and proactive response have been adopted by CPDC in response to climate change and risks under our vision of green petrochemistry. CPDC is also following the mainstream approach of making mitigation and adaptation the two key axes of development for climate change response strategies in order to effectively respond to the challenge and take advantage of its business opportunities. As a leader in the petrochemical industry, CPDC must step up to the plate on climate change. CPDC has long held ourselves to the highest standards by continuing to introduce international management standards aimed at improving energy management efficiency and resilience to climate 68 change. In addition to the introduction of the ISO 50001: 2011 energy management system at three production plants and getting third-party certification, we are in the process of ISO 50001:2018 certification renewal in 2021. In addition, GHG inventories were conducted in accordance with the ISO 14064-1: 2006 specification with guidance at the organization level for quantification and reporting of GHG emissions and removals at the three CPDC plants. Carbon reduction targets were then set based on the results of the inventory. The inventory of energy consumption was used as the starting point for a reduction plan that is gradually developed into climate change action across multiple domains.

3.2.1 Climate Change Mitigation For climate change management, CPDC started by tracking regulatory changes through the Environmental Protection and Pollution Control Center so that response strategies can be developed. At the same time, we are collecting domestic and overseas leading energy-saving and carbon- reducing technologies and provide technical support and experience sharing. For climate change mitigation, led by the president, we set a cross-plant Carbon Reduction Promotion Team to promote energy-saving and carbon-reduction project and hold energy-saving and carbon-reduction meetings once every quarter. Toufen Plant, Dashe Plant, and Hsiaokang Plant propose annual energy-saving and carbon-reduction plans for the following year in the 4th quarter of each year, which will be put into practice after approval by the board of the directors. In addition, CPDC instructs the secretariat team to track the energy consumption, GHG emissions, and reduction benefits of the 3 plants, and regularly review the relevant management policies.

In line with the government's GHG reduction target, each plant's annual energy-saving and carbon-reduction target is "The actual carbon-reduction and energy-saving benefit of the new project must reach 2% of its base year carbon emissions or energy use". Carbon reduction is based on the GHG emissions of the three CPDC plants in 2005, and energy saving is based on the energy consumption of the 3 plants in 2008. In 2020, the actual energy saving for both the Toufen Plant and the Dashe Plant reached the target of reducing the annual energy consumption by 2%. Only the Dashe Plant met the target for actual carbon reduction, while the other two plants failed to meet the target due to the impact of the COVID-19 pandemic on the capacity operating rate.

Definition of actual energy savings and carbon reduction: The amount of energy saving and carbon reduction that occurred in the following year after the results of projects in the previous year were tracked and completed. If the project in the previous year is completed in the following year, it will be calculated in proportion to the remaining month. 4. The base year for the GHG inspection of the Toufen Plant is 2014. The reason for the change is the newly added production line, which exceeds the significance threshold. The base year for the GHG inspection of the Dashe Plant and Hsiaokang Plant is 2005.

In response to international trends and the reduction targets of the "Greenhouse Gas Reduction and Management Act", CPDC has defined the short-term (2025), medium-term (2030), and long-term (2050) carbon-reduction targets. The setting of the short-, medium- and long-term targets will hopefully produce a more comprehensive and far-reaching carbon-reduction plan. At present, the three CPDC plants have proposed plans for the total reduction target at the 2019 Q1 Energy-Saving and Carbon-Reduction Meeting, which is continuously tracked by the secretariat team.

As there is no production activity in the Taipei office, the scope of setting carbon emission target is the three CPDC plants, including Toufen Plant, Dashe Plant, and Hsiaokang Plant

CPDC continues to budget every year for plants to replace old equipment or purchase equipment with better operating efficiency. In 2020, the three CPDC plants invested a total of NTD 133 million to promote 26 new projects. Active efforts are underway to improve our energy conservation, carbon reduction, and water conservation performances to help mitigate climate change. The results are also reported to the competent authorities.

CPDC GHG Emissions CPDC measures the carbon footprint of our business processes against the highest standards. The three CPDC plants conduct inspections every year for scope 1 and scope 2 in accordance with ISO 14064-1: 2006 organizational carbon inspection standards and entrust external impartial third- party organizations to verify our results. No inspections have been conducted for scope 3. An internal inventory with no external verification was completed for the Taipei Office due to its low volume of emissions, most of which came from electricity usage (scope 2). At this stage, we have completed the GHG inventory of regions under the operational control of companies in Taiwan. In the future, we will continue to include new production plants and continue to aim to disclose GHG emissions in overseas regions.

The GHG emissions of the Toufen Plant, the Dashe Plant, and the Hsiaokang Plant in 2020 are self-calculated and shall be verified by external impartial third parties.

71 CPDC continuously monitors the GHG emissions per unit of product. By product category, the GHG emissions per unit of the main products, CPL and AN, have shown a downward trend in the past 5 years. In particular, the Toufen Plant was affected by the COVID-19 pandemic in 2020, and the production was reduced by nearly 50%, resulting in an increase in unit emission intensity.

The GHG emission per unit of product is calculated by using the GWP value from the 4th IPCC report to calculate the annual GHG emissions then divided by total production. 3. The data of the Toufen Plant excludes the GHG emissions from the electricity sales of the co-generation plant and is the actual CPL production emissions data.

Main Product Carbon Footprint Verification CPDC proactively verifies the carbon footprint of its products, in accordance with ISO 14064-3: 2006, and its verification adheres to the ISO 14067: 2018 (CPL/PA6) and ISO14067:2013(AN) standards. We have gradually obtained verification certificates for products such as CPL, AN, and Nylon Chips. Through carbon footprint verification, in addition to providing information for internal carbon mitigation strategies, we also provide more insights enabling customers to understand and calculate their own carbon footprint, further improving the added value to our customer.

3.2.2 Climate Change Adaptation In recent years, international response to climate change has changed from focusing not only on GHG reduction to also giving more emphasis to adaptation. How to cope with and manage the impacts of climate change is one of the key challenges in environmental responsibility for the petrochemical industry due to the nature of its raw materials and processes. The stability of raw materials and the supply chain as well as the stability and safety of the plants are all areas that CPDC will continue to monitor and strengthen in the future. These will be essential to sustainability in a changing environment. The Executive Secretariat of the CSR Committee analyzed the risks and opportunities related to climate change to understand what potential risks and opportunities climate change may pose to CPDC and to support the international sustainability trend of disclosing climate-related financial

72 information. We use the TCFD directive issued by the Financial Stability Board to identify major climate change risks and opportunities for CPDC. In addition, we develop climate change strategies and conduct financial impact analysis on three high-risk climate factors.

Disclosure of Financial Structure Related to Climate Change Framework of Four Major CPDC Management Practices Disclosure of TCFD The CSR Committee is the governance institution for all environmental, social, and governance issues, including climate change mitigation and adaptation as well as energy management at CPDC. The CSR Committee annually reports to the Chairman on climate Governance change and energy management issues (please refer to 1.2.1 Sustainability Governance Framework). For energy management, the Carbon Reduction Promotion Team is responsible for reviewing energy consumption and carbon emissions (please refer to 3.2.1 Climate Change Mitigation) According to the 2°C scenario, CPDC analyzes the risk items under the future climate impact and identifies the impact level on CPDC (for the management and response Strategy related to climate change risks, please refer to 3.2.2 Climate Change Adaptation - Description and Management on High Risk Factors for Climate Change) CPDC uses the climate change risk matrix to identify and sort related risks. Risks path is also used to establish how key risk factors may impact CPDC operations financially Risk and conduct an inventory of response strategies. Please refer to the Identification Process Management of Climate Risks, Risk Matrix, and Description and Management on High Risk Factors for Climate Change in this Chapter. CPDC sets management indicators, including GHG emissions, water resource use, waste Indicators and emissions, air pollutant emissions, etc. We also continue to monitor our energy and GHG Targets emissions (For the setting of each target, please refer to 3.2.1 Climate Change Mitigation and 3.3 Production Environmental Footprint)

Identification Process of Climate Risks Process Steps Description To understand climate change and its impact on financial risks and opportunities, the CSR committee, finance VP chair and invite members Establish Consensus from R&D, petrochemical production, finance, environmental health & safety, market development, to participate in a TCFD workshop, organize the TCFP working group, and establish a common understanding and consensus.

Physical risks include acute and chronic climate change risks. Lastly, 18 items related to CPDC various risk items were also listed. Using the 2℃ global warming assumption, we outlined each factor and its Scenario Setting scenario and impacts. According to the degree of potential impact, potential vulnerability, and Identified major climate incidence rate of risks, we evaluated these threefold directions, listing climate risks, drafting a risk matrix change risk into high, medium, and low ratings. Lastly, we identified "Green Product Replacement", "Cost of GHG Emissions Increases", and "More

77 Climate Change Risk 2℃ Scenario Explanation Impact and Losses to CPDC Factors In accordance with IEA 2017 ETP 2DS Based on the 2℃ Scenario Analysis, scenario, by 2050, the emissions levels should CPDC would have to face additional be 67.1% lower than 2014. Using a linear costs to purchase carbon credits in regression base year of 2015, each year would excess of allowed limits or require require a 3% reduction in GHG, thus, 2050 proactive investment in low carbon would require a 66.1% reduction versus 2015 technology to be able to fulfill the Increase in to fulfill the IEA 2DS scenario. carbon emission roadmap. The GHG investment in renewable energy is a emission costs In accordance with the CPDC target to achieve focus for CPDC, representing 60.6% "2050 emissions less than 50% of 2005 levels", of total low-carbon transformation each year requires a 1.5% reduction in carbon costs. Thus, to fulfill its requirements, emissions. If the base year is converted to CPDC would have to increase its 2015, by the year 2050, a reduction of 41.67% operational costs. compared to 2015 is needed, which still falls short of the 2DS scenario roadmap. In accordance with IEA 2017 ETP 2DS Based on the 2℃ Scenario Analysis, scenario, by 2050, the emissions levels should the national carbon control regulations be 67.1% lower than 2014. Using a linear have been tightened to international regression base year of 2015, each year would standards. Based on the 2°C Scenario require a 3% reduction in GHG, thus, 2050 Analysis, assuming that CPDC can would require a 66.1% reduction versus 2015 achieve its carbon-reduction plan as to fulfill the IEA 2DS scenario expected, it is likely to create stable Energy According to CPDC’s estimated actual carbon carbon trading revenue from 2045 Tax/Carbon reduction of "2050 emissions less than 82% of onwards, and the average carbon Tax 2005 levels", if the base year is converted to revenue through carbon trading credits Regulations 2015, by the year 2050, a reduction of 71% will reach NTD 74.5747 million per compared to 2015 will be achieved, which is year by 2050. Without considering the roughly the same as the 2DS scenario roadmap allocation of credits, if the country and better than the nation's carbon reduction implements a carbon pricing system, roadmap, the Greenhouse Gas Reduction and CPDC may have to pay the carbon Management Act. costs of at least NTD 338 million, or at most over NTD 800 million, based on different carbon pricing standards

3.3 Production Environmental Footprint The production and operation of the petrochemical industry use a lot of energy resources, thus CPDC pays attention to the environmental footprint of its operational process. All CPDC plants have introduced the ISO 14001 environmental management system to reduce the environmental impact of our plants as well as prevent pollution and spills. The management system is enforced to ensure that all emissions and waste produced during plant production are treated in accordance with the law. ISO 9001 quality management system and ISO 45001 occupational safety and health management system have also been introduced at the three CPDC plants. Integrated management maximizes the benefits for quality, environment, and occupational safety and health.

78 Green plant (including clean production and plant green buildings) Starting in 2017, CPDC has started promoting the application of green plant certification. In recent years, CPDC has been successively obtained the clean production and green building certifications, which have been transferred to green plant certification. Currently, all three plants of CPDC are certified as green plants by the Ministry of Economic Affairs, demonstrating CPDC's commitment to environmental sustainability. CPDC has a total of 7 green buildings, with 2 buildings certified as Diamond grade, 1 each of silver grade and bronze grade, 3 qualified grade buildings, and 6 buildings categorized as renovated old buildings. The Hsiaokang Plant Warehouse South Door Office is a new office building, which will be transferred from the waiting list to qualified green building certification in 2021. In addition, the clean production certification of the green plant of the Dashe Plant was extended in 2020 after assessment.

3.3.1 Environmental Policy and Environmental Protection Expenditures CPDC continues to invest in environmental protection as part of our commitment to the environment. We continue to invest in environmental protection policies, such as greenhouse gas and energy management, environmental pollution prevention and control and disclose environmental protection industrial safety incident reports. In 2020, environmental protection expenditure at CPDC mainly went towards external testing of pollutants, waste removal, external research, soil and ground water remediation, air pollution prevention, and process improvements. The total amount spent on each item is listed below. (Violations of environmental laws and regulations are disclosed in 2.3.2 Response to Major Regulatory Compliance Incidents)

3.3.2 Energy Management and Emissions The main types of energy used by the three CPDC plants are natural gas, fuel oil, steam, and electricity. The Toufen Plant has a cogeneration plant that burns coal as one of its sources of electricity. Hsiaokang Plant's energy supply is integrated with other factories in the industrial park. Steam used in production is purchased from nearby China Steel Corporation, a partnership that improves energy efficiency for both companies. In 2020, the renewable energy generation capacity of the Dashe Plant reached 291,552 kWh, and the Toufen Plant and Hsiaokang Plant are under planning. In 2020, CPDC saved 88,187 KLOE in energy consumption. In terms of energy saving and carbon reduction, the Company has 26 projects, which are expected to reduce 12,904 tons of CO2e in greenhouse gases per year. From the total energy consumption statistics of each plant, it can be seen that the energy consumption of products has gradually decreased in recent years.

500kW ORC power generation equipment The Dashe Plant generates a large amount of reaction heat from the AN process by heat exchange to produce high pressure steam and medium and low pressure steam for use in the process. However, the low pressure steam at the end of the process cannot be used due to the low pressure and can only be emitted into the atmosphere. The Dashe Plant has built the first domestic 500kW ORC (Organic Ranking Cycle) power generation equipment, which effectively recovers the heat energy of low pressure steam into electricity and condensate, saving 3,200 kWh of electricity and 49,000 MT of water per year, with a total annual benefit of NTD 10 million. The carbon reduction amounted to 1,674 tons, which is equivalent to 4.3 Daan Forest Park.

81 AN Turbine Compressor Performance Improvement Plan The Dashe Plant AN turbine compressor has been in operation for over 40 years. Due to plant expansions at Dashe, the production volumes are at 132% of the original design, and the turbine compressor operating at excess loading by 17%. Screws and parts may weaken and fail, resulting in unexpected stoppages in production. For stability in operations, we renewed the turbine and improved the performance of the compressor in 2019. The original design for turbine compressor was to use motors and the turbines as the power source. After upgrades, the motors can be stopped and the turbine itself can provide sufficient power, driving a 3% increase in AN production output, saving 8,954,904 kWh of electricity annually, lower carbon emissions by 4,800 metric tons per year, and decrease the failure rate of the equipment. The project was completed in 2020 with the improvement of the second production line, and it was successfully accepted.

3.3.3 Air Pollutant Management CPDC reduced air pollutants emitted during the production process through process improvements as well as upgrades to equipment. In terms of the management system, the three CPDC plants abide by the air pollutant emission intensity per unit product set by the Taipei office every year, as compliance for checking the management of air pollutants. In terms of improvements to the manufacturing process, CPDC abandoned its previous high-emission Cyclohexane process and switched completely over to the Phenol method that produced far less emission, in 2014. The emission of air pollutants was cut dramatically by 50%. A review of CPDC's air pollutant emissions in 2020 showed that the emissions of nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and suspended particulates (TSP) decreased compared to 2019, mainly due to stoppages and single line operations in some months at the Toufen Plant. The improvement project includes the addition of a backup system for VOC tail gas treatment in the Toufen Plant, replacing the original CTO (catalytic oxidizer) with an RTO (regenerative combustion system), with the CTO acting as a backup for the RTO anomaly to improve the stability of the tail gas treatment system. The incinerator cyclone separator and outlet air duct of the Hsiaokang Plant were renewed to stainless steel SUS316 to reduce the corrosion rate of dilute sulfuric acid droplets on the material and sulfur oxide emission. CPDC promises to continue reducing our emission of air pollutants through process refinements and equipment upgrades for the local residents' safety and peace of mind.

Unit: Metric Tons 2. All numbers are rounded to whole numbers

82 3. Emissions for each plant come from self-monitoring and are calculated using monitoring data of the continuous automatic monitoring equipment, the test results, and the published emission coefficients 4. VOCs include hazardous air pollutants and flared/vented hydrocarbons; none of the plants produce Persistent Organic Pollutants (POP) 5. For the calculation of VOCs, CPDC has now switched completely over to the phenol method which produces far lower emissions. Though emissions at Hsiaokang Plant are based on actual readings, Toufen Plant uses the emission coefficient for the Cyclohexanone process published by EPA as required by the competent authorities, so the value is higher than it actually is 6. Only environmentally friendly refrigerants are used at CPDC and no Ozone Depleting Substances (ODS) are emitted during the production process

Construction project of a backup system for VOC tail gas treatment in the Toufen Plant The newly built RTO furnace (regenerative combustion system) is to introduce VOCs into the reactor for heating to make the VOCs in the waste gas decompose into carbon dioxide and water under high temperature environment, and emit into the atmosphere. The heat energy generated in the oxidation process can be stored in the ceramic heat accumulator in the furnace, so that the heat accumulator heats up and stores the heat, creating a high-temperature reaction environment in the furnace and reducing the fuel required to heat the waste gas. Replacing the original CTO (catalytic oxidizer) with RTO with the CTO serving as a backup for RTO anomaly can not only improve the stability of the tail gas treatment system, but also save operating costs such as catalyst, electricity, and fuel, and increase the VOCs reduction rate (90%→95%) to achieve the goal of continuous air pollution reduction.

Renewal of incinerator cyclone separator and outlet air duct of the Hsiaokang Plant The incinerator cyclone separator was originally designed to be made of carbon steel, and the incinerator is currently incinerating mainly dilute ammonium sulfate waste. The flue gas after incineration contains a large concentration of SOx. The flue gas will carry dilute sulfuric acid droplets to the cyclone separator after dissolving salts in the dissolution tank, causing corrosion of the steel plate. The avoidance of corrosion and rupture of the cyclone separator steel plate caused flue gas emissions without the treatment of pollution control equipment to be released into the atmosphere in violation of the Air Pollution Control Act. The cyclone separator made of stainless steel SUS316 is remanufactured to reduce the corrosion rate of dilute sulfuric acid droplets on this material.

3.3.4 Water Resources Management The pattern of precipitation in Taiwan has changed in recent years. Rainfall periods cannot be predicted based on historical trends, leading to an increase in the frequency of heavy storms and extended droughts. The unstable water supply poses a risk to business operations. The year 2020 even witnessed an extreme record, with no typhoon bringing any rainfall during the rainy season, the first time since 1964, causing reservoir level in each area to be on alert. The petrochemical industry is a water-intensive industry that uses a large amount of water during the production process. A stable water supply is therefore critical to CPDC, and water resource management plays a key role in the sustainability of petrochemistry.

83 According to the results of CPDC's TCFD climate change risk identification, "changes in rainfall patterns lead to drought" is the number one physical risk. Besides, the AQUEDUCT Water Risk Atlas from the World Resources Institute was used by CPDC to rate the level of water resource risk at each site. All the three CPDC plants are located in medium and high risk (2-3) regions on water resources. For CPDC, which is located in a high-risk area of water resources and is highly dependent on water resources, rising to the challenges of water change by conserving water will not only reduce a company's environmental footprint and costs. It will also boost the management resilience of CPDC in an uncertain environment. "Zero wastewater discharge" has therefore been set by CPDC as our ultimate goal. The three principles of "inventory", "reduction", and "circulation" now guide further developments in water resource management.

 Inventory: The three CPDC plants actively engage in water consumption surveys. In 2018, we carried out the CPL Water Footprint Inventory in Toufen Plant to check the current water consumption status of products during their life cycle. The inventory results are then used to develop a water resource improvement project and water conservation plan. In 2019, in response to the TCFD project, the three CPDC plants conducted the water stress test and evaluation to simulate the impact of the water supply on production. which was effectively applied to the water restrictions measures in 2020. For the evaluation results, please refer to 3.2.2 Climate Change Adaptation. In 2020, we carried out the CPL Water Footprint Inventory in the Hsiaokang Plant and the CPL and PA6 Water Footprint Inventory in the Toufen Plant to check the current water consumption status of products during their life cycle. The inventory results are then used to develop a water resource improvement project and water conservation plan. In particular, CPL in the Hsiaokang Plant obtained ISO 14046: 2014 verification statement, and CPL and PA6 in the Toufen Plant obtained ISO 14046:2014 verification statement.

All three CPDC plants are located in industrial parks designated by the MOEA and all of their water is supplied by the water utility so there is no need for concern about negative impacts to the water quality and water resources of local nature reserves. In 2020, the total water withdrawal was 7,337 ML, which was all from surface freshwater, the total water discharge was 2,437 ML, and the total water consumption was 4,902 ML. In terms of discharge standards, all effluent from CPDC plants is tested for water quality before discharge and comply with the "Effluent Standards". In 2020, there were no violations of water resources-related regulations by CPDC.

Freshwater is defined as total dissolved solids per liter <= 1000 mg, and other water is defined as total dissolved solids per liter > 1000 mg 6. The wastewater from the three CPDC plants is treated through tertiary treatment before discharge

 Reduction: The water consumption per ton of product for the baseline year (2014) serves as the basis for setting an annual water-saving target of 2% each year. The three CPDC plants carried out a total of 12 water-saving projects in 2020 and the annualized water saving benefit is expected to reach 343,310 metric tons.

The Actual Water Saving of the three CPDC Plants in 2020 Actual water saving Water Consumption per 2% water-saving Achievement benefits in 2020 unit in the base year target (metric tons) Rate (metric tons) Toufen Plant 39 142,135 0 0% Dashe Plant 11.51 48,499 19,755 41% Hsiaokang Plant 21.73 79,228 11,021 14% Note: 1. 2% water saving target = 2014 (base year) water consumption per unit x projected output this year x 2%. 2. The annual water-saving, carbon-reduction, energy-saving, and power-saving targets are all proposed at the energy- saving and carbon-reduction meetings in the fourth quarter of the previous year. Thus, data is calculated based on the estimated output rather than the actual output. 3. Because the cooling water Blow Down recovery system project at Dashe Plant has not yet started operation and been assembled, the actual amount of water saved in 2020 was not included. It will continue to be tracked in 2021.

86  Circulation CPDC is moving in the direction of sustainable water resource management in keeping with the spirit of zero wastewater discharge. We have continued to refine our water recovery technology, including reclaimed water recycling system, ammonia nitrogen wastewater recycling, and carried out the establishment of rainwater recovery system. In addition, the three CPDC plants actively cooperate with external units, coordinate with local governments and manufacturers in industrial areas, and jointly develop the recycled water circular economic. The Hsiaokang Plant responded to the Kaohsiung Wastewater Treatment Plant and Drainage Water Recovery and Reuse Project; the Toufen Plant signed a letter of intent with Guoyang Environmental Technology Company for recycled water. In the future, after the completion of the two projects, 1,000 metric tons and 6,000 metric tons of recycled water will be brought to the Hsiaokang and Toufen plants, respectively.

Waste heat and low pressure steam ORC power generation system at the Dashe Plant AN plant generates more than 15 tons of waste heat and low-pressure steam per hour, which is very wasteful. Therefore, two 500kW low-pressure steam ORC generators were installed from 2019 to 2020, which not only convert the emitted low-pressure steam into electricity, but also recycle it into condensate, which was both energy-saving and water-saving. At present, both units are in operation and can generate about 6.7 million kWh of electricity and save 100,000 tons of water per year. On September 11, 2020, one of the units passed the Energy Bureau's on-site survey and was awarded a grant of up to NTD 5 million for the "2019 Waste Heat and Waste Cooling Recovery Technology Demonstration Application Project".

3.3.5 Waste Disposal Management The concept of the circular economy has been gaining momentum around the world in recent years. In response to the global trend of green environment and the government's 5+2 industrial innovation policy, CPDC has introduced the concept of circular economy into waste management. In addition to effectively collecting by-products, such as crude acetonitrile, hydrocyanic acid, and ammonium sulfate, which are sold as raw materials for other enterprises, we also make changes to the production process to reduce the number of byproducts and waste. Process recovery rate is also improved to achieve the goal of waste reduction at the source. The phenol process developed by CPDC and adopted across the board in 2014 did not just double production output through process improvements, but raw material consumption and byproducts were also greatly reduced to realize the policy of waste reduction at the source. At the same time, CPDC is actively studying the recovery and purification of main and byproducts to identify ways of enhancing the development of circular economy of products. Examples include the recovery of Benzene/Toluene, cogeneration SCR system, cogeneration ESP, recovery of heavy liquids, and activation of anaerobic wastewater system. General industrial waste produced by the 3 CPDC plants generally consists of waste lubricants, non-hazardous organic liquids or solvents, domestic waste, waste timber compounds, construction or building waste mixtures, organic sludge, non-organic sludge, and waste insulation, etc. The main methods for disposal include recycling, incineration, landfill, heat treatment, solidification, and chemical, physical, or biological treatment. In terms of hazardous industrial waste, Hsiaokang Plant

87 mainly produces Chromium and its compounds, Dashe Plant mainly produces waste liquid from extraction and the base of the Acetonitrile column. Disposal is through solidification and incineration. All waste at CPDC is disposed of in accordance with the law. Emission or treatment permits are applied where necessary and reported truthfully to the competent authorities. Most waste is currently disposed of through external contractors while waste liquids at Dashe Plant and Hsiaokang Plant are incinerated internally. The permits for internal incineration currently run until 2024 and 2025. For waste disposed of through external contractors, CPDC uses licensed waste removal and treatment contractors in accordance with the law. Vehicle GPS tracking is used to track waste movements and their final destination. Plant staff also accompany or follow the contractor's vehicles at random to ensure that all waste is being properly disposed of. This prevents the creation of additional environmental burdens or pollution. In addition, CPDC's products are mainly loaded and transported by tank trucks, and only nylon chips and byproduct ammonium sulfate use packaging materials.

The number of waste production is presented as integers and calculated after rounding off 4. CPDC has no chemically treated hazardous business waste, and no hazardous waste was transported, imported, or exported in 2020

3.3.6 Prevention of Environmental Pollution CPDC sets high standards for itself on the remediation and prevention of environmental pollution. Under our vision of green petrochemistry, we have been upholding the basic principle of continuous improvement of the ISO14001 environmental management system for many years in an effort to reduce the negative environmental impacts of our production processes with zero emission as the ultimate goal. Through a complete monitoring system and linkage with local environmental protection bureaus, we can accurately control and monitor the status of each plant and perimeter, aiming to exceed regulations and minimize the impact on the environment. The environmental pollution prevention strategy at CPDC is divided into four levels from inside out: "process waste reduction", "end-of-pipe treatment", "VOCs management", and "environmental monitoring". The Environmental Protection Center at Taipei Office is the top supervisory unit responsible for general planning on emerging environmental protection issues and the tracking of pollution prevention performance. A dedicated team is also assigned to each plant to carry out pollution prevention, monitoring, and improvement operations for each project through the environmental management system.

CPDC's Environmental Pollution Prevention and Control Strategy Process Waste Reduce all types of pollutants produced by production processes through process Reduction improvement, improved production efficiency, waste recycling and reuse. Improve emissions quality and keep all types of pollutants within the standards End-of-Pipe through sorting wastewater for treatment, improving the performance of treatment Treatment facilities, and addition of high-efficiency treatment equipment. VOCs Reduce the dispersion of VOCs through sealed production processes, exhaust Management recovery system, sealed sampling system, and low-leakage equipment components. Environmental Environmental monitoring systems are deployed to keep track of plant air and Monitoring effluent quality at all times.

The system is also linked to the monitoring system of the industrial park Environmental monitoring includes regular mandatory testing at each CPDC plant, as well as the placement of automated monitoring facilities (CEMS) in the emission of fixed pollution sources to continuously monitor their operating status or emission of air pollutants. To maximize the benefits for environmental protection, the facilities are linked to the local environmental protection authorities to improve monitoring and inspection efficiency for both CPDC and the competent authorities.

90 Industrial safety test stations have also been installed throughout each CPDC plant and their surrounding area to ensure the safety of workers. There were no leakage incidents in CPDC in 2020.

3.3.7 Chemical Management Legitimacy is the most basic requirement for CPDC's chemical management. It is also a guideline for protecting personnel from chemical hazards and avoiding environmental pollution caused by leakage. CPDC has established the "Hazard Generalization Operation Procedures", and the three CPDC plants must formulate "Hazard Generalization Plans" and specify the "Hazardous Chemicals List" in accordance with this procedure, which will be handed over to Environmental Protection and Pollution Prevention Center for storage and consolidation. For the management of toxic chemical substances, factories have established the "Operating Procedures for Toxic Chemical Substance Management". Manufacturing, export, import, sale, use, storage, waste toxic chemical substances, and accident handling, all meet the four principles required by the EPA, certificate, application, prevention, and label, and report. The containers with hazardous chemicals in the factory area should be clearly marked according to the prescribed format, including the name, hazardous ingredients, warning words, hazard warning messages, hazard prevention measures, and the name, address, and telephone of the manufacturer, importer, or supplier. Different pipelines are separated by colors so that employees can understand the substances in the pipelines and enhance safety awareness.

Chemical Management in the Supply Chain Phase Description Choose qualified transport contractors and distribute the tank trucks that have passed the high-pressure test according to the process requirements. The driver must receive regular education and training from the factory, and all materials are Transportation transported with special barrels. In addition, vehicles and drivers transporting supplier selection hazardous chemicals must obtain the necessary qualification certificates and relevant licenses in accordance with the law. Each transportation contractor provides GPS of the vehicle to keep track of its movement. When the raw materials are filled from the port to the tank truck, special joints, flanges, and pipelines are used for filling. The operators wear complete protective Chemical loading equipment to prevent the escape of ammonia gas during filling and the possibility of personnel coming in contact with it. After the tank truck enters the factory and is weighed, it must be driven to the operation area according to the designated route. After the on-site employees confirm that the weighing note is correct, the operators wear appropriate protective Unloading in the equipment for unloading according to the standard operating procedures (SOP) and factory work instruction (WI) regulations. Different materials use special joints, flanges, and discharge arms, and gas detectors are also installed on site according to different material needs to maintain safe operation. For different chemicals in the storage area, if there is incompatibility, there shall be a proper distance between them, and they should not be mixed. The storage place shall be far away from fire source, maintain ventilation, prohibit fire and smoke, and Chemical storage prepare appropriate safety protective equipment. Both storage tanks and process pipelines are required to install gas detectors, fire sprinkler systems, and instrument systems and monitor values such as liquid level, temperature, pressure, etc. When the product is sold, special dry joints are used in the filling station. There is a Product special pipeline between the tank truck and the storage tank so there is no problem transportation with leakage or personnel coming in contact with it. We also appointed qualified, heavy duty, and anti-collision tank trucks to transport products.

Chemical Management Education and Employees Health Management CPDC uses a lot of chemicals in the R&D and production process. Therefore, we have continued to implement chemical management education since our employees first reported for duty. The factory's occupational and environmental team has compiled chemical training materials regarding the characteristics of toxic chemicals. Through classes and tests, we ensure that employees are familiar with the characteristics and knowledge of related chemicals, and the exam pass rate in 2020 was 100%. In addition, we arrange practical training on the use of antidotes for toxic chemicals and AED first aid to enhance employees' response ability in the event of an emergency disaster. In July 2020, CPDC’s Dashe Plant cooperated with the Ren Da Industrial Park Service Center, Industrial

92 Development Bureau, Ministry of Economic Affairs to conduct a regional joint emergency response drill to stop the leakage of AN filling stations and tank trucks due to the crash of tank trucks caused by the driver feeling ill. The Dashe Plant belongs to the operation place of toxic chemical substances. In addition to arranging special physical examinations in accordance with regulations, we arrange for all employees in the factory to conduct detailed medical examinations every year with the highest frequency of medical examinations in the industry. By comparing the health check results with the list of diseases that are not suitable for operation announced by the competent authority, we revise the suitability of worker's selection.

Toxic Chemical Reduction CPDC contributes to reducing the use of hazardous chemicals and the generation of hazardous chemical waste and waste liquid. Existing hazardous wastes are treated by incineration. Through the good operation of the wastewater concentration system, the amount of hazardous business waste incinerated in 2020 was effectively reduced by about 2,000 tons compared to the previous year. In addition, we estimate the possibility of improving the conversion rate of AN and reducing the conversion rate of hazardous waste liquid through a new type of catalyst, so as to achieve the effect of controlling the generation of hazardous substances from the source.

93 Chapter 4 Communication and Dialogue 4.1 Sustainable Supply Chain Management As globalization and specialization in international trade continue, the risk management of suppliers and the supply chain sustainability is now a key component of CPDC's sales and production. Raw material and equipment procurement costs represent 89.54% of total costs & expenses, demonstrating the importance of supply chain management to CPDC. In supply chain management strategy, CPDC hopes the relationships with suppliers and customers are based on stable, profitable, long-term partnerships. During the operational process, we jointly take on the responsibility for CSR, lower the impact on the environment, and create a balance between economy and social benefits. We bring our suppliers partners together to draw their attention and work on major issues of human rights, workplace safety, environmental protection, and sustainable governance.

4.1.1 Profile of Supply Chain Management CPDC Industrial Supply Chain Overview CPDC is located in the upper-middle stream of the petrochemical industry value chain. We purchase raw materials needed for production from upstream suppliers to produce AN, CPL, PA6, and OPP products through manufacturing plants. These are then used by downstream customers to produce end petrochemical products. For upstream raw materials, CPDC depends on foreign imports for 100% of its primary raw materials of liquid ammonia and coal. The rest comes from domestic suppliers, to support local procurement and reduce carbon emissions from the transportation of product. For downstream customers, a stable, long-term sales relationship is maintained. Some of our customers have signed supply and sales contracts.

Supply Chain Management Responsible Department The two main procurement departments at CPDC are the Raw Materials Procurement Office and Joint Procurement Office. The Raw Materials Procurement Office oversees the procurement of upstream primary and auxiliary raw materials to ensure the smooth operation of the company's production. This involves market research and analysis for key raw materials as well as supplier development, screening, assessment, and relations management. Joint Procurement Office is in charge of all purchasing outside of raw materials, including production machinery and spare parts, instrumentation, catalysts, and chemical agents. It is also responsible for the contracting of engineering construction projects.

Standards for the Selection of Suppliers The three key indicators of "supply performance and capability", "environmental management", and "ethical business management" described below are used by CPDC when selecting suppliers: 1. Supply Performance and Capability: CPDC selects suppliers based on supply capacity, price, quality, and safety. We also conduct prior visits to suppliers to ensure the stable quality and source of raw materials. Long-term supply contracts have also been signed with suppliers throughout the supply chain. These are supplemented by searching for a greater variety of stable supply chains to reduce the risk of supply chain disruption.

94 2. Environmental Management: CPDC devised the "Supplier/Contractor Environmental Management Questionnaire" because we attach great importance to suppliers' environmental management. Questions are asked (including the adoption of ISO14001, presence of dedicated industrial safety and environmental protection personnel, wastewater and exhaust from processes, etc.) to evaluate supplier performance in the two key aspects of environmental management and environmental protection. Risk assessment is also conducted for the raw material and production process of vendors to ensure that the procurement will not have a major environmental or social impact on the source community. The response rate of the environmental management questionnaire for new suppliers/cooperative factories in 2020 reached 90%. We will continue to promote it to new suppliers in the future. 3. Ethical Business Management: Before a business relationship is established between CPDC and a potential supplier, an ethical business check is conducted to ensure that the other party is a legitimate business that does not engage in unethical behavior, and does not demand, provide or accept bribes.

Supplier CSR Declaration & Commitment Letter For supplier CSR management, CPDC and our main suppliers all make compliance with local laws and regulations a basic requirement. All suppliers must comply with local regulations on corporate governance, environmental protection, labor, and human rights. CPDC hopes that partners can embrace the same sustainable development goals and commitments as we do by respecting the local society, obey national laws, understanding, complying with CPDC's Standards of Ethical Conduct and Company Business Integrity Code during their service delivery. We also hope that they can actively respond to environmental protection, industrial safety, and social issues by embracing accountability and continuous improvement. Since 2016, CPDC has urged suppliers and contractors to sign the "Supplier CSR Declaration &Commitment Letter" and has incorporated the Supplier and Contractor CSR Declaration & Commitment Letter as part of the vendor contracts. Through a voluntary declaration, we hope that vendors will accept, implement and support the ESG (environmental, social, and governance) principles, so as to establish the concept of sustainability in our partners. All of the Company's 827 suppliers signed the CPDC Supplier CSR Declaration & Commitment Letter in 2020.

Supplier Evaluation A supplier evaluation system has been defined by CPDC and an annual evaluation plan is developed each year. The Company conducts visits and evaluations on vendors that completed higher turnover during the year, transportation contractors, and new suppliers; for engineering contractors, the project owner department conducts a supplier comparison once construction is completed for performance tracking and management. Contractors are also required to enforce safety management in accordance with the relevant regulations to ensure that the procurement strategy of CPDC balances the five goals of quality, price, environmental protection, safety, and health. Supplier assessment methods include telephone, email, and on-site audit. In 2020, a total of 19 on-site audits of transportation suppliers were performed, and the rest were communicated by telephone and email. In addition to visiting suppliers to conduct annual evaluations, CPDC also regularly communicates with suppliers and contractors on major industrial safety and environmental protection issues. If there is any negligence, then an incident analysis is conducted to identify the cause and push for continuous improvement. No supplier violations that impact human rights, the environment, labor, or society were reported to the CPDC in 2020.

96 Training for Purchaser and Selection of New Suppliers The Joint Procurement Office regularly implements buyer education and training to enhance the professional procurement skills of the buyers and their knowledge and understanding of the production equipment in the three CPDC plants, so as to make the case handling process smoother and at the same time achieve the goal of saving procurement costs. In the first half of 2020, the course schedule was suspended due to the COVID-19 pandemic. In the second half of the year, two international trade courses were arranged. In addition, in order to avoid excessive reliance on existing suppliers and weaken the ability to control costs and manage risks, new suppliers are introduced, and relationships are established every year. Such measure not only can achieve the effect of controlling costs and improving efficiency, but also allow the Company through new suppliers to learn about new products, without being limited by the fixed transactions and cost models of existing suppliers. By introducing 46 new suppliers, the Joint Procurement Office saved approximately NTD92.37 million in procurement costs in 2020.

Green Procurement and Local Procurement CPDC actively promotes green procurement within the enterprise. We follow the guidelines on the EPA's Green Life Information Website and give priority in purchasing products with Type 1 and Type 2 environmental protection labels. By supporting products that meet the characteristics of reduction, reusable, recyclable, low pollution, energy saving, resource saving, or environmental friendliness, CPDC provides the most substantial support to manufacturers that invest in green manufacturing. In addition, CPDC responds to local procurement and minimizes carbon emissions caused by product transportation. In the future, we will continue to aim at increasing green procurement and the local procurement ratio.

Definition of friendly charity procurement: Purchase gift boxes, fruits, and products from non-profit organizations, social enterprises, disadvantaged groups, and local farmers

Transportation Safety Management To prevent serious environmental and social impacts from improper transportation safety management by suppliers, CPDC conducts regular transportation safety evaluations on transportation contractors. Any areas of poor performance are investigated by CPDC to identify the main cause. CPDC also notifies transportation contractors of relevant results. A re-evaluation is conducted by CPDC at the transportation contractor's next job. If no corrective action is taken, then penalties up to contract termination may be imposed. The evaluation of transportation suppliers in 2020 used 80% as a passing grade. Those who fail to meet a passing grade shall be subject to re-evaluation in the current year. If they fail the re- evaluation, they will not be able to participate in the tendering in the following year. A total of 18 transportation contractors were evaluated in 2020, and 1 failed in the initial evaluation. CPDC has

97 asked suppliers to thoroughly investigate the results and make improvements to any areas of deficiency. Their performance will be used as the basis for supplier selection in the future. In 2020, we added humanitarian action in the evaluation, and improvements to the previous evaluation will be recorded in the future. We also added management indicators and reward and punishment mechanisms for transportation suppliers and require transportation suppliers to purchase additional third-party liability insurance and establish reward and punishment mechanisms, to ensure the stability and sustainability of the supply chain.

4.1.2 Supply Chain Sustainability Risk Evaluation In recent years, it is reported that suppliers and contractors violated human rights, environmental protection, and other laws and regulations, which caused negative impact on companies' reputation. In order to enhance the understanding of supply chain risks, CPDC will continue to strengthen sustainable supply chain management. In 2019, CPDC conducted supply chain risk assessments for suppliers whose annual purchase amount reached NTD15 million or suppliers with high irreplaceable raw materials or equipment, in order to identify the current status of suppliers' sustainable promotion, understand the risk points and be able to respond to them in advance (please refer to the 2019 Corporate Social Responsibility Report for the assessment results). The following lists the supply chain sustainability risk identification process. In addition to the implementation in 2019, we will continue to conduct questionnaire surveys on supply chain sustainability risks and analyze the high- risk aspects of the questionnaire results to understand the sources of risks and strengthen internal management in order to reduce the impact of the risks.

Procedures of Supply Chain Sustainability Risk Identification Phase Description Based on international best practices and industry examples, we designed a self- assessment questionnaire on sustainability risk, the content covers sustainable Survey Design governance and disclosure, occupational safety and health, environmental protection, moral integrity, labor and human rights, etc. Formulate Considering the importance, the first phase of the self-assessment questionnaire was Questionnaire & conducted for the risk of raw materials and equipment suppliers with an annual Dispensing purchase amount of more than NTD15 million, or that is highly irreplaceable Principles 99 Phase Description The number of questionnaires dispensed and collected was used to calculate the Dispensing and percentage of the total annual procurement amount, which were used as the basis for Recovering whether to gradually expand the threshold of questionnaire dispensation in the future, Questionnaire with a view to gradually and completely implement the supply chain sustainability risk assessment Analysis Results Analyze the better and worse aspects and analyze the reasons According to the questionnaire score of each supplier, divide into high-risk, medium- Supplier Rating risk, and low-risk suppliers Strengthening Incorporate ESG ratings into the existing supplier selection criteria, gradually Internal integrate with the supplier scoring mechanism, and require medium- and high-risk Management Act suppliers to continuously improve ESG performance

4.2 Customer Relationships Management 4.2.1 Customer Communication CPDC has set up the "After-Sale Service and Customer Complaint Procedure" to continuously follow up on products after sales to ensure that the quality of products meets customers' needs and maintain customer relations. Therefore, we regularly distribute questionnaires to our customers at the end of each year to conduct customer satisfaction surveys, with a 100% customer coverage rate. The scope of questionnaire survey includes product quality, delivery status, after-sales service, product image, etc. We communicate with the customer to determine what improvements should be made for areas that score below 70. We then review and develop strategies for improving product quality and services. CPDC has also set up an open channel for communication with the customers and established internal procedures for handling customer complaint and improvement to ensure that customer feedback is fully conveyed and reviewed, and proper actions are taken to rectify the situation. In 2020, CPDC received three customer complaints cases related to quality management improvement, improvement on all of them have been completed after thorough communication with customers. We will continue to maintain good relationships with our customers in the future. According to the results of the 2020 customer satisfaction survey conducted by CPDC's Toufen, Hsiaokang, and Dashe plants, all achieved a customer satisfaction rating of over 85 points, indicating that customers were generally very satisfied with the products and services we provide. Among them, the satisfaction level of AN slightly declined compared to 2019. The actual survey revealed that there was an increase in the total number of customers, and the scores of each category reached 90 or above.

4.2.2 Product Quality Management Comprehensive quality management and control procedures are implemented by CPDC at every step from the acquisition of raw materials to their storage, production, and product transportation to ensure that quality products are delivered to the customer. Rigorous internal requirements are enforced to maintain product quality. Safety labels and instructions, as well as the transportation process employs the"5S Workplace Organization" method (Sort, Set in order, Shine, Standardize and Sustain), Total Production Management (TPM), Total Quality Management (TQM), and Hazard and Operability Study (HAZOP) to meet customer expectations to the highest standards. For product safety labeling, hazard labels are applied for CPL, AN, and Nylon Chip products in accordance with domestic regulations. Material Safety Data Sheets have also been produced so that product safety information can be effectively communicated to customers. The quality-first management philosophy at CPDC meant there were no violations relating to the provision and use of our products in 2020, nor any violations relating to product safety labels.

4.3 Social Communications CPDC's three main production plants at Toufen, Dashe, and Hsiaokang are located in Miaoli County and Kaohsiung City. The Qiaotou Plant, completed in late 2020, is also located in Kaohsiung City. We appreciate the importance of securing the support and acceptance of local residents and competent authorities. A variety of communication channels and community relations-building activities are employed by each plant to maintain a positive relationship with their local communities.

4.3.1 Community Communication The most important goal in communication for CPDC is to maintain a symbiotic relationship with local communities surrounding the plants. As far as CPDC is concerned, community communication is the mission of every employee at all times, and every contact with local residents is an important opportunity for communication. As each plant is located in different counties and cities, communication with local communities and residents takes geographic location, customs, traditions, and events into account in order to use the most appropriate method to communicate in the most effective manner. All CPDC plants have a defined "Quality, Safety and Health, Environment and Energy Management Consulting and Communication Procedure" in place to govern the principles and process of stakeholder communications and dialogue. At the same time, complaints can also be made at each plant over the phone or in person. Each plant has a standard operating procedure in place for dealing with telephone complaints or local residents visiting in person. If any improvements are necessary, then actions are taken by the responsible department based on the content of the complaint with follow-up conducted by the General Administration Section.

Complaint Handling SOP at each Plant

Take Effective Action Record, Review, and Complaint Received Verify Complaint and Pollution Control Improve

Inform the complainant the If a telephone complaint or Notify Manufacturing If a pollution complaint is result of action taken. a resident visits in person, section of the complaint to true, then corrective action Record matter in the record the subject of the check if it is true. Go out of is taken by the "External Communication complaint and their contact the plant to check, if Manufacturing section Log" for further review and details necessary immediately improvement

102 In addition to complaints by phone or in person, local residents can also submit their feedback to the local arbitration committee for the plant's location. CPDC plants actively coordinate with the relevant departments and cooperate with their investigations. No complaints were received by the three CPDC plants in 2020.

External Communication by Dashe Industrial Area The CPC's Kaohsiung Plant was closed or relocated in 2015. In Letter Fu-Chien-Tu-Tze No. 211694 dated November 7, 1998, issued by the Kaohsiung County Government regarding "Motions for Changing Dashe Urban Plan (3rd overall review)", the conditions of Motion No. 7 required production plants in Dashe Petrochemical Industrial Park where the Company's Dashe Plant is located to move elsewhere by 2018, and the county government to change it to Class B industrial area according to the legal procedures. The content of the "Motions for Changing the Dashe Urban Plan (4th overall review)" submitted in Letter Kao-Shih-Fu-Tu-Fa-Kuei-Tze No. 10130250600 dated January 13, 2012 by Kaohsiung City Government to the Ministry of the Interior remained unchanged. On March 22, 2019, the Kaohsiung Urban Planning Commission deliberated to change the Dashe Industrial Area from special industrial area to Class B industrial area. Production can still continue in the area, but expansion and rebuilding cannot. Kaohsiung Petrochemical Industry General Union established a self-help association on December 14, 2020 to continuously communicate with the government to degrade to Class A industrial area. At the same time, we request the government to formulate a sunset clause and supplementary measures, so that manufacturers can respond to and relocate the factory in a timely manner. In addition, the establishment of the petrochemical program at Renwu Senior High School as a joint effort between CPDC and other petrochemical companies further enhanced local students and their parents' understanding of the petrochemical industry. A campaign to boost local understanding of the petrochemical industry was also developed to continue strengthening local communication, resolve differences and promote harmony. We hope this will lead to the continued production and sustainable development of the factories within the industrial area.

Adoption of Air Quality Purification Zones and Public Spaces CPDC participates in government environmental protection related activities to promote the development of petrochemical business to the neighboring communities, and also actively invests in environmental improvement and maintenance, which not only can enhance the excellent corporate image and visibility but also achieve a triple win situation for the community, the enterprise, and the government. The Environmental Protection Bureau of Kaohsiung City has been promoting the greening and beautification of exposed earth and subsidizing the establishment of air quality purification zones (hereinafter referred to as “APZ”) for many years. It is hoped that the adoption mechanism by the private sector can enhance and maintain the overall quality and environment of APZ through businesses, maintenance units, or communities working together. In 2020, through the cooperation of the Environmental Protection Bureau of Kaohsiung City and related units, we continued to maintain the APZ. The Dashe Plant continued with the adoption of the APZ of the Yo- Chung Elementary School in Nanzih District. The Hsiaokang Plant continued with the adoption of part of the Kaohsiung Municipal Social Education Center. Both Dashe Plant and Hsiaokang Plant were awarded the 2019 outstanding enterprise for "Air Quality Purification Zone Maintenance". In 2020, the Toufen Plant continued with the adoption of the public space in the Toufen Industrial Area 103 and carried out greening management and maintenance adoptions to improve the landscape and environmental quality, and was awarded a Certificate of Appreciation .

Adoption of Dongxing Wetland Park To protect environmental sustainability and fulfill our corporate social responsibility, Toufen Plant began adopting the Dongxing Wetland Park in Toufen, Miaoli County, in 2013. The wetland is part of the Zhonggang River - Dongxing Bridge Remediation Project administered by the Environmental Protection Bureau of Miaoli County. The Toufen Plant sponsored and adopted the artificial wetland established as part of the project to support its maintenance and management, and the planting of wetland plant species to fulfill the goal of environmental friendliness. CPDC will continue to take an interest in environmental issues in the future.

4.3.2 Remediation and Development of Anshun Site Background Information Anshun site was an alkali-chlorine factory owned by Kagakude Negai O Ka Corporation during the Japanese Period that was later taken over by Taiwan Alkali Industrial Corp. ("Taiwan Alkali"), state owned enterprise. A Pentachlorophenol (PCP) factory was constructed, and production operations continued. When the factory was closed in 1979, around 5,000 kg of PCP was left in the storage on the site. After extended exposure to rainwater, the soil and surface water were polluted by PCP, mercury, and dioxin. In 1983, Taiwan Alkali was merged into CPDC, which was also state- owned at the time, under the directive of the MOEA. Its contaminated land, therefore, became the responsibility of CPDC as well. The contamination is a product of history, but CPDC has worked actively to take responsibility for site remediation. Extensive investment was made into a long-term remediation plan that will gradually rehabilitate the contaminated site. Remediation of the Anshun site is based on the concept of the Remediation Train. The program was launched in 2009 and stage 1 was completed in 2014. Stage 2 of pollution remediation began in 2015 and is expected to be completed by 2024. Between the start of planning and the present day, CPDC has sunk a massive amount of funding into laboratory research, pilot plant testing, project review, and actual plant construction and operation. Local and foreign experts were also invited to review the remediation technologies. CPDC engaged in long-term development of related technologies with an attitude of transforming challenges into growth. Substantial progress has been achieved under the current project timetable and it has now become a model for other international remediation projects.

Main Remediation Methods Heat Treatment Decontamination Technology Wet Treatment Reduction Technology Used for treating soils contaminated with high levels Used for soil with dioxin and mercury of dioxin and mercury. Heat is used to evaporate contamination less than 200 mg/kg. Contaminants contaminants in the soil. Dioxin is broken down by are separated through differences in particle size the high temperature while mercury vapor is and specific weight. Level of contamination can recovered through condensation. The contaminated be reduced by 70%. soil can be 100% decontaminated.

104 Remediation Progress and Procedures On the administrative level, the remediation plan for the Anshun site is supervised by the Environmental Protection Bureau of the Tainan City Government. In terms of its execution, remediation efforts are supervised by the Environmental Protection and Pollution Prevention Center of the CPCD Taipei Office. A joint remediation team is responsible for the implementation of the remediation task. Our personnel regularly produce daily, weekly, monthly, and semi-annual reports on the site, and perform internal inspection through daily sample taking, monitoring, and recording of relevant indicators. Once data indicates abnormal conditions, we will immediately troubleshoot and resolve the deficiency. Also, to effectively communicate to the local government and local community the progress and status of the Anshun site remediation, CPDC performs a construction audit every 2 months, and holds a community town hall meeting and report every 6 months. We invite government and local leaders to participate in the verification of factory testing audits and other opportunities, to ensure the Anshun site remediation information remains open and transparent. The Anshun site has both mercury and dioxin pollutants, which is unique in the world, and the remediation technology is very difficult. CPDC has overcome the difficulties encountered in remediation one by one since the remediation started in 2009. By the end of 2020, a total of 292,400 tons of contaminated soil had been treated and certified by the Environmental Protection Bureau, which was a glorious milestone and a model for contamination remediation technology that can serve as a benchmark for future domestic and international contamination remediation. In addition, CPDC also cooperates with several universities and colleges to conduct research on mercury and dioxin removal technology in soil and has filed patents and published papers. We are also committed to environmental education, guiding the next generation to use this as a reference to care for the environment. Since 2009, 64,100 tons of highly contaminated soil have been treated by the heat treatment on site, and 228,300 tons of medium to low contaminated soil have been treated by the wet treatment on site. According to the third revision of the pollution remediation plan approved by the Tainan City Government, a target of 59,000 tons of contaminated soil shall be treated at the site in 2020, and a total of 59,751 tons of contaminated soil were treated at the Anshun site in 2020, with an achievement rate of 101.3 %.

Environmental Monitoring An environmental monitoring program has been set up by CPDC for the plant and its surrounding environment to effectively control environmental pollution factors and reduce environmental risks, and regularly take and analyze samples, such as air quality, groundwater quality, river water quality, noise, and vibration to track all changes in environmental quality. In addition, other data such as temperature, humidity, mercury vapor, and dioxin are monitored round the clock. The exhaust gas from the heat treatment (rotating kiln) plant and its surrounding environment are monitored as well. Monitoring work can be divided into three categories according to the nature of the work: 107 1. Site environmental monitoring: regular monitoring of environmental quality, such as groundwater, air, noise and vibration, surface water (including river and site drainage), and drainage ditch sediment at the site perimeter or contaminated area 2. Environmental monitoring of treatment units: periodic monitoring of the perimeter environment, exhaust, and drainage of each treatment unit, e.g., when the heat treatment and wet treatment plants are in operation, the perimeter air and wastewater emission values need to be checked 3. Autonomous quality control testing of treatment units: monitor the effectiveness of the treatment process of each treatment unit. For example, the soil after heat treatment and wet treatment has to be verified by autonomous quality control, autonomous verification, and government verification before it can become qualified soil

The environmental footprint of the Anshun site in 2020 was similar to that of 2019. The main reason for the increase in water consumption is to assist the neighboring residents and the Luermen Matsu Temple with watering and irrigation; the main reason for the increase in energy consumption is the reheat operation of the heat treatment equipment after stoppages.

Environmental Footprint of Anshun Site over the Past 3 Years 2018 2019 2020 Electricity consumption (kWh) 1,787,000 3,038,400 3,249,000 Water consumption (KL) 26,811 47,476 82,048 Diesel (KL) 671.2 1,936.621 1,860.9 Waste (Metric Tons) 1.55 2.113 1.074

The water resource management at Anshun site is based on the relevant management regulations as well as the approved remediation plan and water pollution prevention plan. The water sources of Anshun site are provided by the Taiwan Water Corporation. Main purposes include sprinkling water to prevent air-bone dust, irrigating landscaping plants, domestic water, cooling water for factories, etc. In addition, due to the suspension of the ecological pool since 2018, there is no wastewater recovery, and the wastewater discharge is 2,860 metric tons. The quality of the discharged water has been tested. The SS is lower than 25mg/L and the total mercury is lower than 0.002mg/L, which has a higher standard of water quality than Category C water bodies. In the future, water will continue to be reclaimed and reused through RO technology (for irrigation and topping up the eco-pond) at Anshun site to reduce the consumption of water resources. Energy conservation measures will continue to be promoted at Anshun site in the future. The greening rate of the site will also be increased to reduce GHG emissions. Green vegetation remediation technology will be developed and implemented at the same time to reduce or avoid the use of heat treatment. Low-carbon technologies have been listed as a potential remediation solution. Remediation use advanced, low-carbon techniques will allow the remediation goals to be met with a smaller environmental footprint.

Organizational structure and resource allocation 1. Organizational Structure In order to enhance the implementation of the Anshun site remediation and management mechanism, CPDC established a more complete organizational structure of the Anshun Site and set 108 up the "Anshun Plant Pollution Remediation and Management Team" in October 2020, which is led by the Chairman of CPDC Corporation, with the goal of strengthening the Anshun remediation. In addition to the regular discussions at the monthly meeting chaired by the Chairman, we are committed to establishing a supply of environmental protection, social responsibility, human rights, safety, and sustainable development to ensure that the remediation is completed on time and with quality. 2. Resource Allocation In order to strengthen the organizational structure and functions of the "Anshun Plant Pollution Remediation and Management Team", the team gathers CPDC's talents from all levels, such as the Administrative Department, Occupational Safety and Health Center, Environmental Protection and Pollution Prevention Center, etc., to be stationed at Anshun Site to provide supervision, management, technology, communication, and consultation services. In addition, in order to ensure the internal control of all aspects of Anshun Site, the audit unit of the Taipei Office has also upgraded its auditing mechanism to ensure compliance with laws and regulations, as well as focusing on the working environment, employee rights and benefits to fulfill corporate social responsibility. Approximately NTD2.956 billion has been spent on the remediation of soil contamination at the Anshun site between the start of remediation efforts in 2009 and the end of 2020. Remediation funding over previous years is tabled below.

Stakeholder Engagement Multiple communication channels are set up according to the needs of the stakeholders in order to understand the expectations and needs of each party and respond appropriately. 1. Government agencies: mainly the Environmental Protection Bureau of Tainan City Government. The main demands are the progress of remediation and secondary pollution prevention. There are staff from the Occupational Safety and Environmental Protection Center stationed at Anshun site to ensure the safety of the project and prevent secondary pollution and to respond to government agencies' questions immediately in addition to daily inspections of the plant. 2. Neighborhoods: The main targets are the residents of Luermen Matsu Temple, Xiangong Village, Luer Village, and Sicao Village. In order to respond to the needs of neighborhood stakeholders, CPDC has a dedicated staff to respond to and handle the demands of neighbors, while the Luermen Matsu Temple mainly conducts temple fairs and cultural activities. The Company has agreed to lend the parking lot to the temple unconditionally based on the principle of public welfare and good neighborliness. 3. Contractors: Contractors handle the construction of the site according to the contract. In order to ensure the smooth progress of the project, the project is handled by a dedicated person, who is responsible for discussing with the contractors and the Environmental Protection Bureau from time to time

Social Impact 1. Promotion of Academic Development at Local Universities

109 Since the remediation effort was launched in 2009, CPDC has cooperated with 13 local professors in environmental engineering, biological science, and soil science to carry out 16 research projects. More than 30 research experts were cultivated between 2010 and 2013 during Phase 1 of the "Integrated Rehabilitation of Vegetation at Site of Toxic Contamination - Development of Green Technology for Dioxin Contamination at Anshun site" research project. The patent for "Microbial reagents for scavenging dioxin pollutants present in a contaminated medium and methods of using the same" was also licensed to CPDC through technology transfer, resulting in 3 domestic patent applications, a total of 22 domestic and foreign research papers and publications. We provided the tertiary education in Taiwan with the perfect place to put theory into practice. We hosted 2 visits from universities in 2020. The visitors included 50 teachers and students.

2. Best Venue for Environmental Education CPDC hopes that more K-12 students can learn about the story of this land and inspire them to protect the environment. In previous years, Anshun site was opened for schools in the vicinity that applied for environmental education visits. However, due to the impact of the COVID-19 pandemic, many group visits were declined in 2020 due to environmental safety and the seriousness of the pandemic. With the cooperation of many parties, there was no outbreak of the pandemic at Anshun site, fortunately. In the future, the site will be opened gradually, according to the situation of the COVID-19 pandemic, so that people can understand the history of the park and environmental education, and more younger generations on the land can understand the importance of environmental conservation.

3. Landscaping and Carbon Sink Benefits Since the remediation of Anshun site began in 2009, CPDC has invested a lot of resources to remove the contaminated soil and reduce the contaminated area. Since 2011, we have successively completed the renovation of the forest area, single vegetation area, and grass area, and conducted green construction on the 3.3 hectares' forest area. In addition to the native plants in the reserved area, waterways, and building sites, we also added turf and shrub plants, turning the forest area into an environmental education park. The renovated grass area and single vegetation area are all under continuous greening. CPDC hopes to create a sustainable local environment through our efforts.

4. Filming of the Benchmark Achievement of Pollution Remediation Anshun site is contaminated by a number of pollutants and is the only site in the world to be contaminated with mercury and dioxin simultaneously. The difficulty of site remediation is well- known globally. In order to record the brilliant remediation results, the Soil and Groundwater Pollution Remediation Funds commissioned TAIYI Advertising Inc. to visit the Anshun site to film the completed remediation area and the remediation process to facilitate the release of the video of the soil remediation achievement.

The green space is recorded as area, and the formula for estimating carbon sinks is the green area (m2) x20kg- CO2e/m2-yr 2. For the shrub, if survey data is available, the species, quantity, and total planting area shall be recorded (the green space included can be calculated in m2); if not, the total planting area can be recorded, and the formula for estimating carbon sinks is total area (m2) x 300kg-CO2e/m2-yr 3. For the arbor, if survey data is available, the species, quantity, and total planting area shall be recorded (the green space included can be calculated in m2); if not, the total planting area can be recorded, and the new planting can be regarded as small trees. The formula for estimating carbon sinks is total area (m2) x 600kg-CO2e/m2-yr 4. The planting volume also increases or decreases each year. The figures in the above table are the general situation of planting in that year. If the above tree planting figures times carbon sinks, there will be a slight difference from the total annual carbon sinks.

5. Provide Employment Opportunities and Care for Local Residents During the remediation of Anshun site (formerly Taiwan Alkali Corporation), we spend about NTD 2 million per year to hire local residents for remediation work, increase job opportunities and income for local residents, and promote many programs with the city government to drive and improve the local economy. In addition, by holding public welfare activities in Tainan City, CPDC invites local authorities to act as co-organizers, and community groups in Luer, Sicao, and Xiangong villages to set up stalls to sell their products, for public and welfare organizations to join in the fun. CPDC also actively invests in local communication and local operations, establishes good interactions with neighboring villages' offices and community development associations, and actively participates in local community activities. In 2020, we invested NTD43,200 in community activities. CPDC personally promotes living together and prospering with the locals, as well as contributes in the celebration of festivals (Mother's Day, Father's Day, Mid-Autumn Festival, Double Ninth Festival), participation in the Sicao Community Development Association, promotion of the concept of sanitation and pandemic prevention, and care of elders living alone and the elderly in the community. In addition, CPDC allocates an additional NTD 1.5 million to the designated account of the Annan District Office, Tainan City each year as the health care fees for the residents of Sicao, Luer, and Xiangong villages. We hope the local community will recognize CPDC's efforts and together build a sustainable local development for Anshun.

111 Chapter 5 Corporate Care 5.1 Talent Development Teamwork and execution are the two branches of the Company's sustainable development, and talents are the root systems that support the growth of the branches. In recent years, with the development of the dual core businesses of petrochemical and land development and the retirement of senior employees, CPDC's talent recruitment and cultivation strategy has also been adjusted. We actively recruit elite talent with international thinking and transnational capabilities and started an MA program and manager's succession plan. By continuously expanding the talent pool, we strengthen our management capabilities of outstanding talents and accumulate energy for the sustainable development of the Company. The proportion of internal promotion in 2020 reached 34%.

5.1.1 Human Resources Structure CPDC promotes local employment, creates local employment opportunities, and further thrives local development. Furthermore, we care about human rights and prohibit child labor. The total number of employees in 2020 was 1,349, including 1,344 full-time employees and 5 contract employees Due to the industrial characteristics and the current status of domestic talent development, male employees constitute the majority of full-time employees, with a male to female ratio of 5.08: 1 (1,123 male employees; 221 female employees). In order to balance the ratio of male and female in the traditional petrochemical industry, CPDC has actively increased the number of female employees, which has increased by 49.3% compared to 2015 (from 148 to 221). In the future, we will continue to contribute to the women empowerment issue in traditional industries through recruitment and improving human rights and gender equality systems.

Female-friendly workplace CPDC has mostly male employees, and female employees only account for 16.38%. On Women's Day 2020, the chairman sent flowers and small gifts to each level and department to thank the petrochemical female elites. We thank female personnel for their dedication to the Company and family and create a female-friendly workplace.

Annual New Employees and Resigned Employees Statistics CPDC goes to campus and deepens the brand recognition among young students through industry academia cooperation and job exhibitions at colleges and universities. With the petrochemical industry's shift to high-value products and intelligent factory in recent years, and the rapid growth of the land development business, the demand for talents has become increasingly diverse, including chemical industry, land asset management, risk management, reinvestment management, circular economy, big data, AI, and other fields. At the same time, in response to CPDC's overseas business strategy, we promote overseas talent recruitment and training programs and build a frontline battle team to gradually strengthen CPDC's talent pool. Through the inheritance of experience from senior personnel, newly recruited employees can quickly learn in a safe manner to make up for the impact of the retirement wave on CPDC to demonstrate a new atmosphere of sustainable development.

113 Mentorship System for New Employees In order to provide appropriate guidance for new recruits, assist new recruits to adapt to company system and organizational culture as early as possible, help new recruits stabilize work and develop interpersonal relationships, and reduce discomfort with unfamiliar environments, assist new recruits in achieving self-achievement, and improve retention rates, CPDC has a mentorship system for level 2-6 of new non-management employees. The mentors are excellent and qualified senior employees. The term of the mentorship is 3 months and the mentors must be evaluated by the unit supervisor after the end of mentoring task, so as to ensure that the mentors complete the tasks and perform the expected function.

Remuneration System and Performance Management CPDC hopes that our employees will pursue a long-term career development. Therefore, the establishment of a fair, just, and competitive salary structure is the key for the Company. In 2020, the starting salary of CPDC's basic level personnel is NTD30,000, and the starting salary of new graduates from college is NT$35,000, which is 1.26 times and 1.47 times the Taiwanese base salary of NTD23,800, respectively. This means that we provide good competitive salary. CPDC, employees' remuneration structure, includes basic salary, subsidies, additional pay, bonuses, and other payments required by laws and regulations. In order to appreciate the employees' hard work, according to CPDC's "Articles of Incorporation", CPDC distributes 3% of the annual profit as employees' compensation, sharing the sweet results with employees. In addition to the annual festival bonuses, there are also performance bonuses, which can be divided into year-end bonus, monthly bonus, quarterly bonus, and attendance bonus. The achievement of individual performance, departmental performance, plant-wide performance, and other indicators are used as a basis for bonuses distributions. We encourage all employees to work together with CPDC and make efforts in the increase of income source, reduction in costs, and quality maintenance of the Company.

CPDC values equal rights for male and female and equal pay for equal work. We have clear salary, salary scale, and food allowance, which do not differ according to gender. At present, the calculation of the male-female salary ratio adopts the actual full salary as the calculation basis and includes variable salary, such as overtime pay, night pay, shift allowance, performance bonus, attendance bonus, etc. Differences in job function or performance will cause difference in payment. CPDC has more male employees who mainly serve as technicians and do shift works, and fewer 114 females who mainly serve as administrative staff. Therefore, even if the job grades are the same, there are some differences in the salary composition structure, which is the reason for the difference in salary ratios.

CPDC encourages employees to participate in goal setting and performance management. Employees and their direct supervisors together set up departments and individuals key performance goals for business and occupational functions. In addition to the usual business communication and feedback which employees can follow at any time, the direct supervisors shall conduct performance evaluation and performance feedback every six months as a basis of incentive and promotion or an opportunity to help solve difficulties. The proportion of employees receiving performance evaluation in 2020 reached 100% (excluding those who are on leave without pay, contract employees, temporary staff, and those who have been employed for less than 9 months). The performance evaluations of new employees, trainees, and current employees are governed by CPDC regulations such as "Plant Regulations Governing Monthly Performance Evaluations and Incentive", "Regulations Governing Departmental Performance Evaluations and Incentives for the Taipei Office", "Guidelines for New Employee Training and Evaluations", and "Employee Evaluation Regulations". To encourage a proactive approach by employees, outstanding employees from each unit are selected by CPDC in accordance with the "Guidelines for Selection and Recognition of Outstanding Personnel" each year. Such outstanding employees are rewarded with overseas field trips.

5.1.2 Education and Training Extensive resources are invested by CPDC every year into providing employees with a variety of education and training. The training provides employees with the basic skills they need for their work and builds up a pool of expertise for future development and promotion. In addition to on-the- job training, other training includes self-run training courses, external training, and subsidizing employees for self-education. CPDC encourages employees to self-enrich when they are off duty. Therefore, we set up encouragement measures for employees' self-education, which includes job- related courses, foreign languages, public and private universities and colleges, and government- approved training institutions. The number of subsidies in 2020 reached NTD90,000.

5.2 Happy Workplace 5.2.1 CPDC Human Rights Policy The international community is paying more and more attention to the issue of human rights. Inactive actions on human rights will cause the risk of sustainable operation. In order to protect the basic human rights of employees and create a respectful, equal, safe, and friendly working environment, CPDC endorses the “International Human Rights Convention”, "The Ten Principles of the UN Global Compact", "United Nations Guiding Principles on Business and Human Rights", International Labour Organization “Declaration of Fundamental Principles and Rights at Work” and other internationally recognized guidelines, and follows the regulations to establish “CPDC Human Rights Policy” in 2020 as a reference standard for ourselves and related enterprises. In addition to our own employees, we also value the labor rights of suppliers and contractors in each operating base and require external partners not to use child labor. In 2020, there was no cases of child labor in related units. In the future, we will strengthen human rights education training and advocacy both internally 117 and externally, implement our high regard for people, and conduct human rights due diligence procedures.

CPDC Human Rights Policy

In order to fulfill our corporate social responsibility and human rights commitments, CPDC has planned a human rights due diligence process to identify human rights risks and potential issues by reviewing relevant domestic and international issues and domestic labor laws and regulations, identifying groups and stakeholders (such as suppliers, all employees, customers, the general public, etc.) that may be impacted, and conducting questionnaire surveys with relevant units to assess the probability of occurrence and impact of each issue. Based on the results of the questionnaire, we conduct risk assessments on issues with high risk and impact, propose measures to respond to the assessment results, and conduct regular follow-up reviews and timely optimization of human rights policies in an attempt to effectively reduce the impact and influence of human rights risks and improve human rights protection on various issues. In the future, we will conduct human rights due diligence on a regular basis as and when appropriate.

5.2.2 Labor-Management Relations Labor-Management Communication CPDC has established a number of labor-management communication channels to ensure smooth and open communication. These channels are used to listen to our employees to speed up coordination, communication, and response. In addition to the plant and company-level unions that 120 serve as the primary official channel for communication with employees, employees can also submit their feedback and suggestions through the Employee Welfare Committee, employee grievance channels, and other less formal, routine channels of communication to the company depending on the nature of the incident.

Labor-Management Communication Channels Communication Description Channels Plant- and company-level labor-management meetings are held every quarter for Union two-way communication between labor and management representatives.

Grievances Channel mailbox: [email protected]

Union Membership and Operation CPDC has established four unions in Taipei Office, Toufen Plant, Dashe Plant, and Hsiaokang Plant in accordance with the Trade Union Act. The unions act as the spokesperson for all employees. The union presidents are elected from among the 9 directors. A supervisory committee made up of 3 supervisors elected separately by the union is responsible for supervising the operation of the union. The four unions at CPDC operate independently of each other. The Toufen, Dashe, and Hsiaokang unions have also set up a joint committee chaired by union representatives from each plant in rotation. The committee convenes directors' and supervisory meetings at each plant for sharing and studying legislative information as well as promoting harmonious labor-management relations. Regional and company-level labor-management meetings are convened every quarter between union and management representatives at CPDC. The company-level labor-management meetings are chaired in rotation by labor and management representatives. In 2020, CPDC hosted 4 labor- management meetings to discuss issues such as the performance evaluation system, group insurance, employee bonuses, and food allowances. After each labor-management meeting, CPDC issues a response to every motion passed at the meeting and tracks their subsequent progress to ensure that every item is implemented in full. Employees are also notified of any important announcements. At present, except for the appointed managers, 100% of the employees of the three CPDC plants are covered by the collective bargaining agreement.

Routine Communication and Grievance Channels CPDC management uses meetings or other suitable occasions to keep employees up to date on current developments in the company and Taiwan's petrochemical industry as well as future business opportunities. If mass layoffs are required due to a major change in the business, advance notice exceeding the minimum notice period will be given in accordance with the" Labor Standards Act" and "Act for Worker Protection of Mass Redundancy". The CPDC policy and spirit of "putting people first" means that nobody should be subjected to discrimination or harassment. Employment will be terminated in accordance with Article 57 of the "Work Rules" for any serious incidents involving discrimination or gender equality. Sexual harassment cases will be handled in accordance with the rules and process set down in "Guidelines for Establishing Measures of Prevention, Complaint and Punishment of Sexual Harassment in the Workplace". Sexual harassment committees dedicated to the handling of sexual harassment cases have been established at the Taipei Office and each plant. Under the CPDC's "Guidelines for Dealing with Employee Complaints", employee complaints and feedback are the responsibility of the management section at each plant and the HR unit of Taipei Office. Once a complaint is received by the responsible unit, it is forwarded to the appropriate unit to take action if necessary or be reported up the chain of command. In 2020, CPDC had one labor grievance case in which an employee was paid insufficient wages for unpaid compensatory time off

122 when leaving the Company. CPDC had paid back wages to the employee after inspection. (For details, please refer to 2.3.2 Response to Major Violations)

5.2.3 Employee Benefits Group Insurance In addition to providing every employee with mandatory Labor Insurance and National Health Insurance as required by law, CPDC provides group insurance policies for employees as well to protect their lives and enhance their welfare. Group insurance includes life insurance, accident insurance, cancer insurance, and medical insurance. To show compassion and care for our employees' families, we also provide our employees' parents, children, and spouses with group medical insurance at a reduced cost.

Health Examination As employees are the company's most important asset, employees' health reflects the company's business performance. Annual health examinations are organized by CPDC for employees to help them understand their own health. If an employee must engage in work with higher levels of risk, then special health examinations are arranged by CPDC to avoid assigning employees work that their health is unsuitable for. In 2020, the cost of health examinations was up to NTD 5,544,250.

Employees who meet the qualifications for retirement can apply according to the procedure. CPDC provides a complete retirement system to take care of the lives of retired employees. In addition to pension payments from the national labor insurance, we set up a labor retirement reserve supervision committee according to the law and allocate monthly retirement reserves. Employees who are employed after the implementation of the Labor Pension Act in 2005, or choose to work under the system, monthly contributions are made to the Labor Retirement Reserve Supervision Committee Bank of Taiwan Bank's old system retirement reserve account in accordance with the law. For employees covered by the new pension system, CPDC makes monthly contributions equal to 6% of the employee salary to their individual labor pension account with the Bureau of Labor Insurance. In addition to corporate monthly 6% contribution, personnel can choose to allocate 0~6% of their salary to the retirement fund account. In addition, CPDC encourages employees to save and has set up the "Employee Shareholding Trust Procedure ". Through joint trust, employees can invest in the company's stocks, hold them for a long time, and work together for the company's operation and profit to achieve a win-win goal for both labor and management. Employees can contribute up to 10% of their salaries and bonuses each month as personal deposits. CPDC will also make equivalent deposit amount to the employees' shareholding trust as rewards. The trust holding fund account is used by the trustee to purchase CPDC shares. After a certain period of time, employees can apply for partial withdrawal or continue the trust in accordance with the provisions of the trust contract.

CPDC's Exercise Culture "People" are the most precious assets of an enterprise and the key to its sustainable operation. To promote the healthy development of employees, CPDC actively creates a quality environment for employees to work and be healthy at the same time. In addition to the establishment of sports clubs of different nature in each plant, some plants are equipped with badminton courts, softball fields, fitness equipment, etc. Every year, four major healthy activities are held regularly across plants, including table tennis tournaments, badminton tournaments, softball tournaments, and joint hiking. This also helps to enhance the interaction and communication between the employees and the officers in different plants, and build up the team spirit. In 2020, CPDC spent a total of NT$1.063 million on health promotion activities (including physical fitness and external sports competition subsidies).

CPDC and CPDC Dashe Plant were jointly selected as 【2020 i-Sports Company】 The Sports Administration, Ministry of Education has been promoting the i-Sports Certification since 2017 in order to promote a disciplined exercise culture among the general public and employees. CPDC passed the review for the first time this year, and CPDC and CPDC Dashe Plant (which applied separately) were jointly selected as the 【2020 i-Sports Company】.

5.2.4 Occupational Health and Safety An occupational safety and health management system has been put into place by CPDC to continue maintaining, improving, and promoting the working environment and health of employees. The system covers all operational activities, products, and services involving each CPDC plant and occupational safety. At present, there is an Occupational Safety and Health Committee (hereinafter referred to as "OSH Committee") at the Taipei Office and each production plant. Each quarter, an OSH Committee meeting is held. 4 meetings were held by each committee in 2020. The OSH Committee is made up of both labor and management representatives as required by law and chaired by either the president or plant chief. Labor representatives, who jointly review, coordinate, and establish occupational safety and health-related matters, account for more than one-third of each OSH Committee. The president sets the annual industrial safety goals each year. The goals for each plant 125 are announced so that they can focus on promoting key parts of the industrial safety policy. The OSH committees are also responsible for tracking occupational injuries and diseases within the Company. Such incidents must be reported to the OSH committee during the quarterly meeting and adhere to reporting procedures. Any corrective actions should be done and publicized as soon as possible to prevent similar incidents from happening again. The newly established Qiaotou Plant and Douliou Plant will also establish an OSH committee in accordance with the regulations.

Hazard identification and risk assessments have been conducted at the three CPDC plants. The identification of high-risk factors and processes was used to manage the risks and opportunities of occupational safety and health so that CPDC can obey the related rules, and lower the impact on our employee's health and safety. CPDC develops response strategies and corresponding improvements to continue strengthening employee risk awareness and reinforcing the importance of safety protection.

Industrial safety and environmental protection are major issues for CPDC. In addition to the Plant Chiefs of the three CPDC plants reporting the progress of the industrial safety and environmental protection project in the monthly business report, the promotion of supervisors at all levels must also pass the assessment of industrial safety items. Besides, any material news or changes, discussion of resolutions and resolutions related to occupational safety and health shall be regularly communicated with employees through the OSH Committees and labor-management meetings. The collective bargaining agreement signed between CPDC and the plant unions also provides protection for employees' workplace health and safety.

Industrial Safety Risk Management The Occupational Safety and Health Center is in charge of safety and risk management at CPDC. The Industrial Safety and Environmental Protection Section at the Hsiaokang Plants, and the Industrial Safety Section at the Toufen Plant and Dashe Plant all cooperate with the Occupational Safety and Health Center to promote and implement the relevant policies and measures. The three CPDC plants have received the ISO 9001, ISO 14001, ISO 45001, and TOSHMS and ISO 50001 certifications. In 2019, the Hsiaokang Plant received the Kaohsiung City Government approval as a high-performing safety and health unit (valid until June 2021). Hazards identification and risk assessment methods are also in place for environmental protection and occupational safety and health. These along with the corresponding management, monitoring, and improvement measures are used to prevent environmental, safety and health-related disasters within our plants. Emergency Notification Procedure and Emergency Preparation and Response Control Procedure have been established at the Taipei Office and each plant as well to ensure that response measures can be activated in time when there is an accident, for damage control and post-disaster recovery.

127 Process Safety Management CPDC has applied AI image intelligence analysis technology to high-risk industrial safety operations and environmental issues to optimize human-machine collaboration and reduce hazard risks. "Process Safety Management" has been designated by CPDC as a key focus area of industrial safety over the past few years. In 2016, CPDC began leading the push to integrate the system of "Process Safety Management" into existing EHS systems and gradually established an integrated PSM system for the three CPDC plants by promoting 14 PSM work tasks. Through problem identifying, procedure documents drafting, training and promotion plan activities executing, and regular reviewing by PDCA cycle, CPDC could achieve process safety, stable production, and protection of personnel from any accidents, such as fire, explosions, leaks, or any other major incidents due to procedural mistakes. In accordance with the requirements of the International Council of Chemical Association's (ICCA) Global Process Safety Indicator Reporting Guidelines, CPDC has incorporated the Tier II process safety leakage threshold limit value of API 754 standard for process safety events to be reported into the Company's Emergency Notification Procedure. Each plant has also set the Tier II process safety leakage threshold limit value for chemicals. If an excess of Tier II process safety leakage threshold limit value occurs at each plant, a quick report must be made.

Process Safety Management Promotion Procedures Process Description Taipei Office and the three CPDC plants separately establish the PSM Establish promotion team and PSM executive team and establish dedicated personnel Organization in charge for each project promotion Evaluate Evaluate and inventory current conditions, using industry peers as Current benchmarks Conditions Implement assessment and testing system for employees in process hazard Strengthen analysis (PHA), management of change (MOC), and pre-startup safety Training review (PSSR) to enhance the ability of the performing employees The designated supervisor is responsible, and the PSM executive secretary Execute Plan of the plant area assists in the implementation of various PSM projects The plant area holds a monthly PSM promotion review meeting, a Regular quarterly PSM promotion meeting convened by the vice president of the Verification petrochemical production department, and conducts compliance audits on the process safety management of the three CPDC plants, annually Connect PSM with performance assessment indicators to establish a Link to KPIs corporate culture of valuing process safety

Expected Benefits of PSM Implementation  Can effectively prevent fire, explosion, leakage, and other major disasters.  Establish the company's PSM organizational structure and related management procedures and methods and meet the requirements of the US Occupational Safety and Health Administration's (OSHA) regulations and domestic laws, with the possibility of on-site implementation.  Implement Mechanical Integrity, establish equipment and pipeline deterioration assessment mechanism, analyze the occurrence and failure probability of various damage mechanisms and further calculate the remaining life of equipment pipelines, formulate detection strategies, and

128 implement reliable and effective inspection and maintenance methods for critical pipeline equipment.  When the factory is equipped with hazardous equipment (such as the first type of pressure vessel, high-pressure gas specific equipment) which contains catalyst, molecular sieve, or other special substance, it is necessary to apply for an extended internal inspection period for review. Promoting the implementation of the PSM system can meet the auditing conditions of the labor inspection agency.  Continue to promote the Hazard and Operability Study (HAZOP). In 2019, the Class A hazardous workplace of the three CPDC plants has been reported in accordance with the Ministry of Labor’s “Enforcement Regulations Governing the Regular Implementation for Process Safety Assessment” (in accordance with Article 8 of the regular implementation regulations of the process safety assessment of the Ministry of Labor, it shall be reported to the labor inspection agency for recording every five years).

Pipeline Safety Management The Company provides chemical safety data sheets (SDS) at the operation site for the operators to check, and the management of each chemical is in accordance with international and national regulations. In addition, there are many pipelines on the site for the process. To avoid confusion in identification, we have posted the Global Hazardous Substances (GHS) icons on chemical storage tanks, containers, and pipelines in accordance with international regulations to enable employees to clearly understand pipeline fluid substances. In addition, in order for on-site operators to identify hazardous fluid pipelines in a clearer and easier way, we collect and refer to the foreign industry practices. For flammable, explosive, toxic, and other dangerous fluid pipelines, CPDC strengthen the labeling on pipeline flanges and valve outlets, top and bottom of the inspection, risk of fluid splashing, and other operations that need to identify the location of the pipeline fluid so as to enhance operators' hazard potential identification on pipelines.

Underground Pipeline Maintenance and Management To strengthen the transportation of underground pipelines, effectively manage underground pipelines outside of the plants, and establish a sound management procedure, in 2015 CPDC began submitting an annual pipeline maintenance plan for the following year to the Kaohsiung City Government for review at the end of each year. Confirmations have also been obtained from Kaohsiung City Government. The four main risk indicators of pipeline design, corrosion, improper operation, and third-party damage along with factors such as leakage and impact are used for assessment and classification of overall risk. To effectively monitor and manage the transmission safety of regional underground pipelines as well as carry out continuous maintenance, CPDC Dashe Plant and other related petrochemical companies set up the Regional Defense Organization for Underground Pipelines of Kaohsiung City. Dashe Plant serves as the administrative liaison for the No. 6 Conduit Organization, responsible for internal and external administration, correspondence, and coordination. CPDC Hsiaokang Plant became the Vice President and emergency response representative for the No. 2 Conduit, responsible for promoting the sharing of emergency response and joint defense experience for its pipeline cluster as well as the organizing of education, training, and drills. Most of CPDC's external underground 129 pipelines have now been shut down and scrapped. Only one backup AN pipeline running from CPC to the Dashe Plant is left. The pipeline has been preserved by nitrogen sealing and cathodic anti- corrosion prevention. Nevertheless, the Dashe Plant and the Hsiaokang Plant continue to play a supporting role for each conduit to fulfill our social responsibility.

Coal Bunkers and Anoxic Workplaces Management Coal bunker is a statutory anoxic operation place, and isolation measures are taken. CPDC posts precautions for anoxic operations at the entrance of the coal bunker, and provides on-site equipment such as breathing protective gear, ladders, safety belts, or lifelines to ensure the safety of the operators. In order to strengthen the safety of coal bunker operations, we conducted work contact before construction to confirm the health status, operation content, and safety protective equipment of the workers on the day. All operations must follow standard operating procedures, hazard identification, and risk assessment results, and plan related operational processes to reduce the possibility of occupational accidents. CPDC strengthens environmental management in the field of confined space operations and also installs ventilation equipment in places that may be lacking oxygen. Personnel or contractors must wear oxygen, hydrogen sulfide, methane, or other harmful gas concentration measuring instruments during operation, and monitor with surveillance at all time to avoid the disaster of coal pile collapse. In addition, CPDC regularly arranges personnel to conduct workplace inspections and audits. Abnormalities shall be immediately improved or reviewed to avoid the recurrence of abnormalities.

Risk Monitoring and Management CPDC uses the PDCA method to evaluate the industrial safety risk management mechanisms. The Occupational Safety & Health Center regularly establishes " Quality, Environment, OSHA Management System internal audit annual plan and checklist", and "industrial safety and environmental site visit audit plans". Personnel from the Taipei Office and the three CPDC plants, who have passed internal audit training and earned certificate, execute quarterly audits and annual overhaul audits of plant and R&D center, and China Business Division audits. Targeting deficiencies and providing rectification plans until all deficiencies are improved.

Industrial Safety Incident Response and Actions In addition to regular monitoring and review of environmental, industrial safety and health management systems at the plants, an incident notification, response, and investigation process has also been developed by CPDC. If there is an environmental or industrial safety accident such as leakage, fire, or explosion at a plant, the incident must be reported to the Audio/Visual Command Center of Taipei Office in accordance with the Emergency Notification Procedure. The Taipei Office must also act and issue a public response immediately.

130 Each CPDC plant has its own "Emergency Preparation and Response Control Procedure" and "Emergency Response Plan". This enables the most effective emergency response and management that is tailored to their local conditions in the event of a disaster or accident. CPDC divides emergencies and disasters into three levels based on their severity and scope. The extent of response and notifications changes according to the level to ensure that communication and cooperation can be maintained with plant employees, nearby plants in the industrial area, and local competent authorities. An "Incident Investigation and Follow-up Management Process" was also developed for all types of incidents in order to investigate in detail, report and record the incidents of all environmental safety and health at the plants. The "Corrective and Preventive Action Procedure" then ensures the effective execution of corrective actions to prevent the accident from happening again. In 2020, CPDC has no contractor deaths, and the contractor's LTIFR is 1.66. In 2020, Dashe Plant suffered 1 major safety incident. The follow-up examinations, discussions, and improvements are as follows:

Statement of Dashe Major Safety Incident The safety incident was caused by an instantaneous high-temperature arc generated by the arc energy, resulting in high-temperature burns to two construction workers. The injured were immediately classified and treated for burns on site, and ambulances were contacted to take them to the Naval General Hospital for medical treatment. During their hospitalization, the plant nurses provided necessary medical consultation and assistance. The Dashe plant conducted a review of the incident and commenced a comprehensive inventory of the drawer-type switchboard and fixed switchboard in the plant. Fixed switchboards should be specifically marked and warned of power-off operations while establishing relevant control measures. On the management side, it is required to clearly classify the scope of operation of the plant operators and contractors, strengthen the education and training of plant personnel to enhance the safety awareness and alertness of personnel. It is also necessary to require the project contracting unit to list specific information and preventive measures to be taken according to the environmental conditions, main hazard contents, and hazard factors of the operation projects. For high-risk operation projects, contractors are required to provide work safety analysis (JSA) and implement education and training for hired employees or subcontractors and keep records. On the institutional level, we should establish the relevant implementation regulations for electrical live line operations, and make clearer definitions for electrical live line operations and related personnel, so that all personnel have the same awareness and implement relevant regulations.

In addition to management and maintenance from the source and risk assessment, emergency response drill is conducted at different times each year. A suitable plan of emergency response drill is designed for each plant based on their requirements to effectively manage the risks from industrial safety, long-distance underground pipelines, and emergency events, improve the emergency response capabilities of our personnel, and implement a multi-faceted risk management policy. CPDC has determined, in accordance with the list of occupational diseases defined by the Labor Insurance Act, that occupational diseases with potential risks from our routine operations include: AN poisoning and related complications, occupational hearing impairment, Benzene/Benzene homologue poisoning, and related complications, Hydrogen Chloride/chlorine compound poisoning and related complications. CPDC continues to provide our personnel corresponding health

131 examination for occupational diseases, so that we can ensure all personnel are protected from the harm of occupational hazards.

Recordable occupational injury refers to the injury of the victim without loss of working hours or loss of working hours for less than one day 7. CPDC has set the threshold for reporting process safety incidents in the " Emergency Notification Procedure, in which, the threshold for reporting is reached with the injury or death of a person or the loss of working hours reaches more than one day, or when any employee inside or outside the plant needs to be hospitalized for treatment 8. The boundary of this report is the Taipei Office and the three CPDC plants (Toufen, Dashe, and Hsiaokang Plant plants). As the new Qiaotou Plant has occupational safety and health performance result, it is included in the statistics (Qiaotou Plant started operation in October 2020)

Employee Caring and Support Plans CPDC commits to providing employees with medical and health services, such as resident doctors and nurses to handle on-the-spot services, and the promotion of mental and physical wellness programs. The plants are equipped with an infirmary and basic first-aid facilities are located at the sites. Automated External Defibrillator (AED) devices have been installed at the Taipei Office and all three plants. Annual health examinations are arranged for all personnel along with related health guidance and education. To ensure the health of our employees, CPDC provides annual health examinations. The content of the health examination depends on the manufacturing process and use of chemical materials by plant. Employees at the Toufen Plant undergo additional checks for Benzene, dust, n-Hexane, noise, and ionizing radiation; employees at the Dashe Plant undergo additional checks for Mercury, Nickel, ionizing radiation, and Chromic Acid; employees at the Hsiaokang Plant undergo additional checks for Benzene, noise, ionizing radiation, Formaldehyde, and Potassium Dichromate. The results from the three CPDC plants have been reported to the local authority and Workforce Development Agency, Ministry of Labor. The regular and special health examinations are used to understand the mental and physical health of employees so that the optimal arrangements can be made at work. (For regular employee health checkups, please refer to 5.2.3 Employee Benefits) We also provide pre-service health examinations for new employees and use this as a basis for suitable work assignments. If an employee must perform work with special health hazards, then

133 special health examinations are organized by the Company, and the relevant information is submitted to the competent authorities for reference. Besides, health classification and management have been implemented by each plant in accordance with the Regulations of the Labor Health Protection issued by the Ministry of Labor of Executive Yuan. We monitor the physical health of every employee and track those with health issues.

As new plants (Qiaotou Plant and Douliou Plant) have conducted employee health activity management, the new plants are included in the statistics (Qiaotou Plant started operation in October 2020, and Douliou Plant is currently managed by Toufen Plant)

Workplace safety is another important potential risk factor at CPDC. These are due to an inadequate understanding of each plant's internal operating procedures and safety management regulations by external contractors. For the effective management of contractor safety and to reduce the risk of joint operations, contractors' contracts at all production plants must include Work Instructions and Contractor Safety Management Procedure as attachments. Contractors are required to carry out safety management in accordance with the relevant regulations. Contractors are also required by CPDC to convene a preparation meeting before the start of work to ensure the personal safety of all internal and external personnel during joint operations.

134 To help familiarize contractors with the plant environment as well as industrial safety, health, and environmental protection regulations, the three CPDC plants conduct industrial safety seminars and training for contractors during routine operations or annual overhauls. In 2020, contractor training was conducted for 5,422 persons across the company and the percentage of trained personnel reached 100%. To ensure that all contractors are properly trained before the start of work, CPDC maintains a registry of trained personnel and produces certificates with the holder's photo attached. The training certificate and registry are used as the basis for the issuance of access passes.

5.3 Social Charity Participation 5.3.1 Social Charity Approach Guided by our founding vision of “giving back to the community,” CPDC is also committed to “community engagement for symbiotic growth” for social care. We make our operating locations the starting point to work together towards the three axes of “petrochemical education,” “support for rural schoolchildren” and “elderly care.” We are in alignment with the United Nations Sustainable Development Goals of No Poverty (SDG1), Good Health & Well-being (SDG3), Quality Education (SDG4), Reduced Inequalities (SDG10). CPDC's social welfare investment strategy is carried out in two ways: the Corporate Relations Section of CPDC Taipei Office is responsible for coordinating the planning and organizing CSR activities every quarter, including accompanying the elderly and caring for the disadvantaged, combining the theme of "sending love to the rural areas" and integrating environmental education issues, such as understanding the chemical industry, environmental coexistence, energy saving and carbon reduction into public welfare activities; the other part is evaluated and handled by each plant, giving priority to serving the surrounding neighborhood and disadvantaged units, or actively responding to CSR activities organized by the competent authorities. CPDC continues to set up a budget for social welfare investment every year. In 2020, a total of 152 CSR activities were held, with an expenditure of approximately NTD15.722 million. The volunteer culture that has been gradually established since 2017 has attracted more personnel to the volunteer services in 2020, with approximately 425 participating volunteers and approximately 2,487 people being served in a single year.

136 5.3.2 Petrochemical Education Through an industry-academia partnership, CPDC has continued to develop and secure the future petrochemical talent pool. In 2020, CPDC cooperated with Taiwan University's Department of Chemical Engineering, Petrochemical Class of Renwu High School, and other educational units to organize petrochemical-related professional courses and camps, providing young students with the opportunity to get in touch with the operation practices of the petrochemical industry, and to understand the industry content, importance, and CPDC's corporate characteristics and development visions.

Industry-Government-Academia Strategy Alliance at Renwu Senior High School A strategic alliance was formed between CPDC and other petrochemical plants in the Dashe and Renwu regions to establish a partnership with Renwu Senior High School. The first Renda petrochemical program was launched in 2015 to bring together school, industry, and government resources for motivating student interest in learning, expanding industry knowledge, and cultivating future job skills. In 2020, the Petrochemical class special workshop "Green Energy and Circular Economy" follows international trends and demonstrates to students the transformation for the petrochemical industry due to environmental topics, which received the CommonWealth Parenting magazine's attention and reporting. This program was well received by external parties, and in 2018 held a renewal ceremony, extending the industry-academic partnership program to 2022. In an effort to actively attract talent to enter the petrochemical industry, CPDC established a priority employment pathway for students that graduated from the "Renda Petrochemical Program" to the Dashe Plant as a full-time engineer. In addition, the CPDC's Dashe Plant also provides 1~2 graduates with internship opportunities every year, hoping that such practical experience can enhance their understanding of the petrochemical industry and accumulate the competitiveness for future employment.

Hosted the NTU Chemical Summer Science Camp plant visit In order to fulfill corporate social responsibility and cultivate chemical talent, CPDC has been cooperating with the NTU Chemical Summer Science Camp for a long time. In 2020, for the seventh time, we assisted in arranging the group to visit CPDC 's Toufen Plant. Through detailed explanation and introduction, a total of 113 high school and university students had a better understanding of chemical plant operations, products, processes, and production technologies, and learned to wear safety protection equipment for practical experience. We hope that after the visit, the students could strengthen their interest in the chemical industry and move toward the chemical industry in the future.

5.3.3 Local Engagement The Corporate Relations Section of CPDC is responsible for planning and organizing at least one social welfare activity per quarter. In 2020, due to the impact of the COVID-19 pandemic and the government's pandemic prevention measures, the activities were suspended in the first half of the year, while CSR activities such as the "Free Gifts" and the "CPDC Public Welfare Bus" were

137 conducted in the second half of the year, attracting enthusiastic responses from all employees (including employees from the plants). The three CPDC plants of Toufen, Dashe, Hsiaokang, and the Tainan Anshun site (formerly Taiwan Alkali Corporation) also voluntarily organize or co-host community events according to local needs. During the pandemic, CPDC even cooperated with or hosted donation of materials and other related charity activities. Through donations, participation, and scholarships, the Company has been able to bring residents closer, and establish friendly interaction and communication with local village chiefs, unit responsible person, community, school teachers and students. CPDC set up the “1314 Anshun Neighborhood Scholarship” at Siangong Elementary School and Jhenhai Elementary School near Anshun site (formerly Taiwan Alkali Corporation) that is under remediation by the Company. CPDC also subsidized after-school care at the two schools. A total of NTD320,000 was invested for the year, hoping to motivate students to continue learning, boost their confidence and sense of achievement, as well as enhance their character and academic performance through the scholarships and after-school care classes. This has earned us the gratitude and appreciation of the schools, students, and parents for many years. In 2020, CPDC invested a total of NTD15,722,242 in local participation, including rural care, community networking, donations to communities, donations of pandemic prevention materials, and sponsorships for activities held by local governments.

Joint pandemic prevention through love and care CPDC Toufen Plant donated two batches of sodium hypochlorite to Toufen City Office and Miaoli County Council and discussed with local authorities and public representatives on pandemic prevention issues to contribute to the prevention of the pandemic. CPDC Dashe Plant cooperated with the Dashe District Office and joined hands with the manufacturers in Dashe Industrial Park to support the "Warm Hearts for the Future" campaign promoted by the Kaohsiung City Government and sent the collected products to the disadvantaged people in the Dashe District through buying pre-orders products from multiple stores in the Dashe District. It has brought a lot of warmth to the community affected by the of the pandemic. In collaboration with the Blood Donation Center, the Toufen Plant held its first blood donation event in the plant. In an active response to such activity, a total of 43 employees donated 16,500 c.c. of blood.

1314 free gifts mobilization CPDC cooperated with "Give-Circle" for the first time to hold the "Love Box Delivery" public welfare activity and launched a donation campaign at 5 office locations. The campaign's goal of 30 boxes was reached within half a month, with a total of 480 kilograms and 1,260 items donated, reducing 988.8 kilograms of carbon emissions for the earth. The materials went to 10 counties and cities across Taiwan, and 19 public welfare organizations and schools benefited. The campaign met five SDGs goals, including Reduced Inequalities (SDG 10), Sustainable Cities and Communities (SDG 11), Responsible Consumption and Production (SDG 12), Climate Action (SDG 13), and Partnerships for the Goals (SDG 17).

138 Christmas Charity Bus On Christmas Eve 2020, CPDC held the second "CPDC Charity Bus" activity. Our employees volunteer to buy the gifts from the wishlists of the children of two rural elementary schools in Bao Lai Elementary School, Liouguei District, and Neimen District, Shi-Men Elementary School in Kaohsiung City, which triggered enthusiastic response within the Company, and all 69 gifts were collected within 4 hours. On December 17 and 18, the Corporate Relations Section took the teachers and students from the two schools to experience astronomy and watch a 3D astronomy film at the Tainan Astronomical Education Area and gave the collected Christmas gifts to the children in person. This event is now in its second year and will be held at the end of every year to become a regular event so as to fulfill our CSR and bring warm wishes from our partners in CPDC to the children in rural areas.
