2009 Case Studies and Supplementary Information

Environmental Annual Report Honda 2009 Case Studies and Supplementary Information Environmental information disclosure Honda discloses its environmental policies and practices in the CSR Report, in the Honda Environmental Annual Report and on its website (http://world.honda.com/environment/). The CSR Report outlines Honda’s environmental initiatives in an easy-to-understand way. The Environmental Annual Report presents in greater detail Honda’s fundamental policies and future direction with respect to the environment, as well as the results of the year’s environmental initiatives. In addition to covering both general and specific environmental information, the website presents the history of Honda’s environmental initiatives. Starting this year, Honda is presenting the report in two parts: “Honda Environmental Annual Report 2009” and “Hon- da Environmental Annual Report 2009: Case Studies and Supplementary Information” are both available on the website, and “Honda Environmental Annual Report 2009” is also available in printed form. As restructured, the printed Report will play an even stronger role in our Plan, Do, Check and Act (PDCA) process for environmental initiatives. The Case Studies and Supplementary Information document supplements the information con- tained in the printed Report, introduces additional initiatives in each domain and presents Substances of Concern output data for each Honda facility and product area. Honda produces the Honda Environmental Annual Report based on internal guidelines. By disclosing a wide range of information, we hope to facilitate communication and feedback, thereby strengthening our environmental conservation initiatives going forward.

Global Operations and Marketplace Advancing operations in six regions Driven by its philosophy of building products close to the customer, Honda manufactures its products in six different regions worldwide. In FY2009 we delivered 23 million units to customers around the world. Always conscious of the environmental impact of its operations, Honda is working hard to take environmental responsibility to ever higher levels around the world. In 2006 Honda became the world’s first automaker to announce

global CO2 reduction goals for its products and production activities. It also implemented a proactive strategy to help stabilize climate change, taking efforts to even higher levels. As a global manufacturer, Hon-

da strives to develop products with the lowest in-use CO2 emissions

manufactured at plants with the lowest per-unit CO2 emissions. Honda Group companies worldwide continue to advance a wide range of initiatives for the reduction of environmental impact.

4 Honda Environmental Annual Report 2009: Case Studies and Supplementary Information Reduction of in-vehicle VOCs

Since October 2007, all Honda automobiles sold in Japan have met the guidelines for in-vehicle VOC content man- dated by Japan’s Ministry of Health, Labor and Welfare. Honda is the first automaker to achieve these standards for all automobiles, including commercial vehicles.

Case Studies

Exhaust emissions

Even cleaner Odyssey emissions The completely redesigned, fourth- generation Honda Odyssey was released in

October 2008. It is available with a 2.4-liter Integrated cylinder head i-VTEC engine that combines reduced exhaust manifold

precious metals content with enhanced Linear A/F sensor emissions performance. The latest model High-heat-resistanct O2 sensor features a newly developed integrated catalytic converter

cylinder head exhaust manifold and an Under-the-floor catalytic converter extremely heat-resistant catalytic converter located directly beneath the manifold. Together, these technologies maintain a highly efficient system for purifying exhaust emissions with reduced use of rare precious metals. The Odyssey features a linear air-fuel ratio sensor, an oxygen sensor and an air-flow sensor for high-precision air-fuel ratio control, while a high-atomizing fuel injector helps reduce exhaust emissions. These technologies give the Odyssey enhanced emissions performance, allowing certain types to be certified as very low-emission vehicles by Japan’s MLIT. Introduced in 1994, the Odyssey reached cumulative sales of one million units in Japan in February 2009.

Designing the 3R’s (reduce, reuse, recycle)

Resin intake manifold in Insight Honda sought to maximize fuel efficiency and environmental performance in every detail of the 1.3-liter gasoline engine that serves as the Insight’s main source of power. Be- tween the cylinder heads and the intake manifold, Honda placed an EGR plate with highly efficient exhaust pathways. The implementation of this technology allowed for the use of a lightweight composite-resin intake manifold, helping to reduce overall vehicle weight.

Sales results for compact household cogeneration systems

A cogeneration (heat and electricity) system generates electricity with a gas engine and uses the exhaust heat to supply hot water. Overcoming the challenge of creating a system compact enough for household use, in March 2003, Honda began sales of a cogeneration unit that combined the GE160V—the world’s smallest natural gas engine—with an electrical generation system featuring Honda’s original sine wave inverter technology. In Japan, a cogeneration system that incorporates Honda’s compact household cogeneration unit has been sold through utility gas companies under the brand name ECOWILL. In October 2006, Honda introduced a new unit featuring power generation efficiency of 22.5% and total energy efficiency of 85.5%. In FY2009, in Japan Honda sold 20,021 units of the ECOWILL cogeneration system. Cumulatively, Honda has sold 86,285 units since its release.

Noise reduction

In December 2008, Honda launched the Yukios SB800, a compact and lightweight snow thrower that clears snow with a blade in an easy-to-use fashion. In addition to exceptional fuel economy, the Yukios SB800 features low noise. When the user releases the throttle lever, engine rpms automatically decrease for enhanced fuel economy and reduced noise during idling. The use of a resin engine cover further reduces noise to facilitate early morning snow removal. In February 2009, Honda introduced the Pianta FV200 gas-powered mini-tiller, which runs on home-use butane gas canisters. As with the Yukios SB800, when the user releases the throttle lever, engine rpms automatically decrease to reduce noise. In addition, noise is reduced through the use of a large silencer, provided as standard equipment, along with a plastic engine cover.

Other initiatives

Alternative energy

Advances in solar cell production and sales In October 2007 Honda Soltec began commercial production of non-silicon CIGS (copper, indium, gallium and selenium) thin-film solar cells developed by Honda Engineering. The width of the energy-generating layers of CIGS solar cells is approximately 2.4 micrometers, roughly 1/80th the width of polycrystal silicon cells. Produced with fewer processes and less energy than polycrystal silicon cells, CIGS solar cells have an approximately 1/3 shorter energy payback time (the time it takes to recover the energy used in cell production) of 0.9 years. One challenge faced in the development of CIGS solar cells concerns the ho- mogeneity of the energy-generating layer. Whereas polycrystal silicon has a maximum cell size of 15 cm, Honda can produce CIGS substrates that measure as much as 73×92 cm. To accomplish this, Honda implemented such original technologies Installation at Kumamoto Factory as in-plane temperature distribution with high-temperature processing exceeding 500°C and doping technology based on automotive coating technology. Honda thin-film solar cells have a highly efficient 11.15% energy-conversion rate. Honda Soltec has begun selling the cells throughout Japan.

Recycling of used molds

Since most molds are made of metal, they are recycled. However, since some molds are used for many different service replacement parts, it can be difficult to determine when they can be recycled. In FY2003 Honda began sharing guidelines with suppliers on mold recycling, leading to standardization of procedures and more proactive recycling.

Results for FY2008 Results for FY2009

• 10,119 molds recycled • 9,760 molds recycled • 1,410 tons of molds recycled • 1,360 tons of molds recycled

Transportation

Reducing packaging in the transportation of component parts sets

Completed motorcycles importation and power products transportation By using returnable cases when importing scooters from China, Honda is continuing to maintain zero landfill disposal of shipping materials. By eliminating the use of cardboard and introducing returnable steel containers, Honda continues to reduce packaging use. In addition, through the use of returnable steel cases for transporting medium and large marine outboards in Japan, Honda is continuing to reduce steel and cardboard use.

The Honda Beach Clean-up Project As one of our community initiatives, Honda developed the Beach Cleaner, which is used to clean up the seashore. A group of current and retired associates assembled a volunteer caravan to work with municipal authorities to put this inno- vative device to work. The towable Beach Cleaner has a simple structure based on the functions of a rake and a sieve. As it churns up the sand, buried litter is collected for proper disposal. In FY2009 the Beach Cleaner Caravan visited 32 sites in Japan and with the help of more than 1,600 current and retired associates some 6,000 bags of litter were collected. Starting in FY2010, the associates working for dealers in local communities will also participate, further expanding the scope of the initiative.

Honda Environmental Annual Report 2009 : Case Studies and Supplementary Information 13 Honda Group companies case studies Maximizing the use of microgrid-generated energy

• Automobile R&D Center, Honda R&D Co., Ltd.

Aiming to be an R&D center with the world’s smallest environmental footprint the Automobile R&D Center implements advanced environmental initiatives in three categories: reducing greenhouse gas emissions, reducing output of harmful chemicals and using resources efficiently. In particlar, to combat

the worldwide problem of CO2 emissions, the Automobile R&D Center is working to reduce its CO2 emissions to 85% of the FY2001 baseline by 2010. One advanced alternative energy technology the company is using to accomplish this goal is its microgrid power generation and storage system.

Microgrid management leads to high efficiency

With its 2.5 million m2 campus, the Automobile R&D Center is as big as a small town. Here the company performs engine burn-in tests and other lifespan testing, as well as driving tests, and some machines run 24 hours a day. The Automobile R&D Center makes each element of its operations as environmentally responsible as possible and constantly implements a wide variety of environmental initiatives.

Among its initiatives to reduce CO2 emissions, the Center runs an advanced microgrid power generation and storage system. A microgrid is a network of multiple, distributed power generation sources man-

aged to provide stable power on demand and capable of reducing both CO2 emissions and energy costs. With a view to maximizing energy efficiency, the Center implements centralized monitoring, management and operation of the generation and delivery of electricity and heat. In 2008, the company connected existing drive power sources, HVAC systems, electrical equipment and power generation systems including the microgrid with a local area network (LAN), establishing a comprehensive management system on the Center’s intranet. Visually intuitive, the system allows the associate in charge to view the energy production and use status in real time and make appropriate decisions.

One of the world’s largest NaS battery systems

The microgrid system of the Center comprises two cogeneration systems, two sodium-sulfur (NaS) battery systems, an alternative energy production system that derives power from waste fuel VOCs (volatile organic compounds) and a solar power generation system. The two NaS battery systems are particularly advanced: adding to the capacity of the 1,500 kW NaS Battery System No. 1, the 12,000 kW NaS Battery System No. 2 began operation in September 2007 and, as of June 2009, is the world’s largest NaS battery system. These two systems are especially helpful during the frequent power outages that occur due to the region’s numerous electrical storms. Among energy storage batteries, NaS batteries have an especially high charge and discharge efficiency. They efficiently store power during those times of day when energy is cheaper and help provide a consistent supply of power. This system also helps stabilize the Center’s power supply during times of peak demand in the summer while reducing the burden on the local power infrastructure,

14 Honda Environmental Annual Report 2009: Case Studies and Supplementary Information thereby contributing to society. An NaS battery system may also be used as a back up to solar-power generation systems and other renewable energy sources, which typically have large fluctuations in the amount of power they generate. Added to the 1,253 kW Cogeneration System No. 1 in April 2008, Cogeneration System No. 2 uses a gas turbine to generate up to 7,000 kW. In addition residual fuel is used for power generation in VOC processing. The Center has also increased solar power generation from 112 kW to 156 kW, allowing the microgrid to provide an optimal power supply with low CO2 emissions. The total amount of power the Center uses is equivalent to the amount used by 30 to 40 thousand typical house- holds; of this amount, the Center purchases 90% from the public utility and generates 10% in-house through alternative energy. Going forward, the Center will continue to develop its microgrid system, aiming for the most environmentally responsible method of operation possible.

Thanks to advanced devices, original innovations and Honda’s own patented technologies, Honda Engineering has developed a proprietary water treatment system that is highly effective. Leading the way in solving environmental problems and using water resources effectively, Honda Engineering is aiming to recycle 100% of the water it uses and produce zero wastewater by 2010.

Aiming for Japan’s cleanest wastewater and 100% recycling

In 1990, when Honda Engineering began its move from Saitama Prefecture to Tochigi Prefecture and submitted a proposal for its water treatment facility, the company had the idea of producing wastewater that was even cleaner than the water of the Shimanto River on the island of Shikoku, a river famous in Japan for its cleanliness. The future site of the company was in the town of Haga near the Nomoto River, an area of great natural beauty where people make the river part of their everyday lives. Tochigi Prefecture, where local water needs to be appropriate for agricultural uses, has one of the strict- est wastewater quality standards in Japan. Since Honda Engineering is engaged in the research and development of manufacturing technologies, the wastewater it produces changes on a daily basis and contains a wide variety of chemical substances. To deal with this uniquely challenging set of circumstances, Honda Engineering has created a leading-edge water treatment system. Expanding its operations and increasing its water usage since its move from Saitama Prefecture, Honda Engineering has adopted a new policy of recyling wasterwater instead of discharging it. Rather than discharge wastewater into the Nomoto River, the company decided to make the water cleaner and reuse it in its own facility. Participating in the Green Factory project, Honda Engineering established the goal of producing zero wastewater by the year 2030 in order to conserve water resources. Since then, Honda Engineering has accelerated its efforts, introducing higher-level treatment equipment for both ordinary (sewage, etc.) and industrial wastewater. Currently, the company is aiming for 100% recycling of water by 2010. In pursuing this goal, in FY2009, Honda Engineering purchased 61,500 m3 of water and exceeded the target to recycle 56,216 m3. Thanks to the savings achieved by purchasing less water and treating less wastewater, the investment in additional equipment was recovered in two years. In February 2009, Honda Engineering stopped purchasing water for industrial uses and discharging ordinary wastewater and expects additional savings to result.

Using membranes for industrial wastewater treatment

In processing ordinary wastewater, Honda Engineering uses a biological treatment method that utilizes 3,000 species of bacteria instead of treatment methods based on physical chemistry. The company processes wastewater and sludge using proprietary technologies, for which the company has registered over 10 patents. Honda Engineering manages the bacteria with precision control, adding oxygen and nutrients with precision. To select and control the bacteria that will help achieve the necessary water quality, the company has established a treatment management and testing regime built upon many years of testing and experimentation. In 1990, the company added two underground tanks to the No. 1 Plant capable of processing 140 m3 of ordinary wastewater per day. This system was ahead of its time in the use of iron contactors, only the third private facility in Japan to implement the technology. In 2004, Honda Engineering built a second ordinary

16 Honda Environmental Annual Report 2009: Case Studies and Supplementary Information wastewater treatment facility capable of processing 420 m3 per day, adding an ultrafiltration membrane separation process to the biological process. Water made clean by the ultrafiltration membrane is further treated with activated charcoal, making it appropriate for use as coolant water and for other uses in the factory. Honda Engineering’s industrial wastewater treatment facility is capable of handling the wide variety of substances produced by the company’s ever-changing research and development operations. Completed in 1997, the No. 1 Industrial Wastewater Treatment Facility treats wastewater from electroplating machines. A water treatment product called Fabios was implemented, in which microorganisms adhere to a fine fiber medium that may be exchanged. Completed in 2005, the No. 2 Industrial Wastewa- ter Treatment Facility was one of the first private treatment facilities in Japan to deploy membrane technology. At the time, it was believed that membranes could not be used to treat wastewater containing heavy metal ions, but Honda’s experiments proved that if reaction processing, nitrification and denitrification were performed in advance, separation with ultrafiltration membranes could be used. The system that Honda Engineering created transformed steps that had conventionally taken place in the latter half of the treatment process into pre-processing steps. This industrial wastewater treatment facility has a daily processing capacity of 160 m3. Today, to recycle industrial water, Honda Engineering further treats the water from this process with reverse osmosis, which prevents small particles and ionized matter from passing through the filter, turning it into salt-free water suitable for human consumption. Honda Engineering uses this water as coolant or toilet water.

Maturing technologies in Japan and introducing them to Honda facilities throughout the world, Honda engages in Green Factory initiatives that advance the level of manufacturing technology and environmental responsibility. Completed in March 2009, the new plant of the Tochigi Factory features solar power generation, plant-based thermal insulation, waste heat recycling, heating via a geothermal heat pump and other environmentally responsible technologies that contribute to its status as an environmentally responsible facility.

Solar power generation and green roof

At the Tochigi Factory, primarily responsible for manufacturing automobile engine and powertrain parts, a new facility for research, development and manufacturing of powertrain components was completed on March 20, 2009. Known as the L10 Plant, the new 10,000 m2 facility contains a production area on its first floor and offices, meeting rooms and research laboratories on its second floor. A unique, next-generation facility with a wide variety of environmental innovations, the L10 plant is designed to be hospitable to associates and the local community and the planet. The new plant features a Honda-developed 12 kW solar power generation system installed on a frame on the facility`s second floor—the second such system in the Tochigi Factory complex. Powering the lights of the office and meeting rooms, Solar panels the system includes a display for real-time monitoring of the amount of sunlight received and power generated. In addition, in two areas totaling approximately 400 m2, the roof is covered with Phyla nodiflora growing in white sand, providing an attractive green appearance and thermal insulation.

Plants growing on roof

18 Honda Environmental Annual Report 2009: Case Studies and Supplementary Information Environmentally responsible HVAC and lighting

The L10 Plant uses both a geothermal exchange pump and recycled waste heat from production to provide heat for the HVAC system. The geothermal heat pump takes advantage of constant underground water temperatures to provide heat, and additional heat is derived from the used coolant water of the forging press. Combined in a hybrid configura- tion, these two heat sources help reduce the energy consumed by the facility’s HVAC system. Lighting in the L10 Plant has also been designed for optimal efficiency. Sunlight is captured on the roof and directed via prisms down a tube to provide natural light to the offices below. LEDs light the meeting rooms, using less energy and providing a longer lifespan than incandescent or fluorescent lighting. The processing of water used in production for reuse in toilets is another example of the environmental initiatives implemented at this plant. The L10 Plant is designed for efficient conservation of energy and resources. Its attractive green roof, natural lighting system and people-friendly logistics help make it a hospitable environment for all associates. The environmentally responsible design of the new L10 Plant makes it a welcome addition to the Tochigi Factory and the company.

Honda Environmental Annual Report 2009 : Case Studies and Supplementary Information 19 Honda Group companies case studies Solar power generation system performance boosted 15%

• Tsuzuki Manufacturing Co., Ltd.

Tsuzuki Manufacturing Co., Ltd. is a Honda affiliate engaged in manufacturing of transmission components and other important components for automobiles and motorcycles. In 1999, the company achieved ISO 14001 certification and is implementing ongoing initiatives to help conserve the global environment. After installing in November 2006 a solar power generation system, which produces electricity with zero

CO2 emissions, the company went on to modify the system to maximize its performance.

Tsuzuki enhances solar power generation system

The headquarters and factory of Tsuzuki Manufacturing are located about 30 min- utes by car from Ueda Station in Sakaki, Hanishina District, Nagano Prefecture, in a mountainous area near the Chikuma River. The company’s three plants in Nagano mainly produce front suspensions, lower arms, damper forks, stator shafts and other components for Honda automobiles, as well as gear shift spindles for Honda motorcycles. In November 2006, Tsuzuki Manufacturing installed a solar power generation system on the roof of its No. 3 Plant, which produces the rotor shaft for the Insight

hybrid vehicle. The company is aiming to reduce CO2 emissions by 16.7% from the FY2000 baseline by FY2011, and decided to make solar power generation part of their strategy. In 2006, Honda became the first automaker to enter the solar panel industry, making the move an even more natural fit. In addition, as a company seeking to gain the appreciation of local society, Tsuzuki believed solar power was an ideal form of energy, since its use can contribute to environmental conservation. In October 2006, Tsuzuki installed a 40 kW solar power generation system but ran into a problem that winter: snow tended to linger on the panels, preventing them from generating electricity. Comparing the installation to others in the region and analyzing the problem, Tsuzuki associates determined that they actually faced two problems. First, sunlight being blocked by the surrounding mountains led to limited exposure of the panels to the sun and the resulting relatively persistent snow accumulation. Second, at temperatures above 30°C, the panels were comparatively less efficient. The associates decided to enhance the system to achieve more efficient powergeneration.

The orchard next to the factory provides a hint

To improve the performance of a solar power generation system, it is necessary to concentrate sunlight. The hint that led to part of the solution of Tsuzuki Manufacturing`s problem came in the form of reflective sheets lying in an apple orchard behind the factory. Apples farms are numerous in Sakaki, and farmers put out silver sheets in great numbers on the ground to reflect light onto the apples and enhance their color. Tsuzuki Manufacturing associates thought to use these same sheets to reflect light onto the solar panels. After deciding on the angle to use and the overall design, in August 2007, associates created a frame to hold the sheets un- derneath the four rows of panels. In addition, they added a reflective panel to the wall whose angle could be adjusted on the spring equinox, summer solstice, autumn equinox and winter solstice to take advantage of the different angles of the sunlight. When light hits this movable panel, it is reflected onto the reflected sheets and from there onto the solar panels, and this dual reflection further concentrates the light. The use of these reflective surfaces improves the performance of the system by 12%. On the wall with the movable panel, associates changed the windows from frosted glass to glass with reflective film, to maximize the light reaching the solar panels.

20 Honda Environmental Annual Report 2009: Case Studies and Supplementary Information To combat the panels’ lower performance at higher temperatures, Tsuzuki devised and installed a system of hoses that wrap around the panels, distributing water through small openings. The hose system provided the benefit of melting the snow and keep- ing the panels in operation. The hose system provides water in the summer when the temperature is above 30°C to cool the panels and in winter when snow falls to prevent accumulation. Although on average in Sakaki it snows only 9.6 days per year, the snow tends to accumulate, preventing the panels from operating for extended periods. Thanks to this system, the amount of electricity generated during the hottest time of day (12:00 noon to 2:00 p.m.) went up 3.8%. To improve the performance of the cooling process, associates added anti-clouding agents and surfactants to the water to prevent it from run- ning only in narrow paths across the panels.

New ideas inspired by environmental initiatives based on ISO 14001

As a result of these innovations, from December 2006 to November 2007, Tsuzuki Manufacturing saw a 34% increase in power generation over the rated level of the solar panels, resulting in a reduction of approximately

22 tons of CO2 emissions per year. In 2008, two years after implementing the changes, the performance profile for the system had risen 20% as com- pared to the previous year. In the months in which performance decreases the most, June to October, the Tsuzuki Manufacturing system achieved a 9% increase in efficiency. In contrast, comparable systems in the region logged a decline in performance for the same period of 0.9%. In the Tsuzuki Manufacturing system, the increase in performance attributable to the cooling system was 1.6%, to the reflective panels 12.0% and to the reflective window film 1.4% for a total of 15.0%. To enhance the performance of the solar panels themselves would have required a significant investment in R&D. Instead, Tsuzuki Manufacturing demonstrated the viability of enhanc- ing system efficiency through innovations after installation. Within the factory, associates can easily track the power generation status of the rooftop panels via a monitor. The innovations used to enhance system performance made an impression on the associates particularly because their impact is readily appreciable. At Tsuzuki Manufacturing, each department develops energy and resource conservation and other environmental initiatives based on ISO 14001, involving all associates in these efforts. Pursuing challenging goals to conserve the environment can lead to new innovations, and the enhancement of solar panel performance by Tsuzuki Manufacturing associates is an example of how simple ideas can lead to significant results.

Associates at Honda automobile dealerships play an important role in reducing the environmental impact of dealer operations through their ongoing efforts to reduce usage of electricity and gasoline. In order to raise awareness of the importance of environmental footprint reduction measures among its associates, Honda Cars Aichi has since 2006 participated in Team Minus 6%, a Japanese Ministry of the

Environment-supported initiative. All dealership associates are working together to reduce CO2 emissions.

Posters with participating company’s names printed on them provided by 2,216 2,171 2,010 Electricity the Ministry of the Environment are displayed in showrooms to help promote public

awareness of the initiative. Associates’ business cards also display the Team Minus 2006 2007 2008 6% logo as part of the effort to promote awareness of this environmental conservation initiative.

Introduction of cool biz, warm biz practices

Cool biz, warm biz, a Team Minus 6% campaign, encourages businesses to create an environment in which people feel comfortable working with the air conditioner set at a higher temperature in summer and the heating set at a lower temperature in winter. At first, some thought it would be difficult to implement this program in the dealer showroom, as it would mean not only setting air conditioners to eco mode in areas where customers are negotiating a purchase or waiting for their cars to be serviced, but also allowing sales and front office staff to go without neckties. However, Honda Cars Aichi used its enrollment in Team Minus 6% as an opportunity to promote the importance of environmental conservation to its customers, who in turn praised the company for its environmental stance. These measures, once considered

difficult to implement, are now broadly accepted. Team Minus 6% poster

Eco Drive workshops

Honda dealerships’ environmental impact reduction initiatives go beyond merely reducing their own environmental footprint. They also take the opportunity presented through their safe driving workshops to teach Eco Drive workshops, in which customers are instructed on efficient

driving practices that help reduce CO2 output by reducing fuel consumption. In FY2008, Honda Cars Aichi held two safe driving workshops at each of its 52 dealerships, totaling 104 workshops. Of the customers who participated in these workshops, 506 were also taught the key points of efficient driving in Eco Drive classes.
