Strategic Directions Expanding Renewable Energy Projects Response to Climate Since the government-led National Greenhouse Gas Reduction Roadmap in 2030 was established In 2018, the government-led National Greenhouse Gas Reduction Roadmap 2030 was Change in 2018, companies are facing stronger demands to disclose information regarding their established and publicly announced. In order to achieve the GHG reduction target of 37% against obligations to reduce greenhouse gas (GHG) emissions. In response, we systematically manage the BAU* baseline by 2030, the importance of developing and mass-distributing innovative data regarding fuel consumption by all corporate vehicles and energy consumption in corporate renewable energy technologies is being highlighted. Against this backdrop, KEPCO KPS, as a buildings by recording them on the National Greenhouse Gas Inventory and Research Center. leading company creating eco-friendly energy, is using its outstanding maintenance technology We also make continuous efforts to reduce GHGs by building an eco-friendly renewable energy and knowhow accumulated over decades in developing and supplying renewable energy resource business portfolio. systems. In particular, we provide O&M service for renewable energy facilities, such as solar, wind, and small hydro power facilities, and energy storage system (ESS) projects, utilizing our technical Reduction Activities of Greenhouse Gas Emissions expertise in engineering.

As a result of these efforts, we reduced GHG emissions by 23.5% against our baseline, a reduction ratio adding a remarkable 20.7% to the 2017 ratio (2.8%). Our GHG emissions are on the rise because the number of corporate vehicles has increased due to an expansion of business areas. However, we continuously reduce our energy consumption by practicing energy reduction and efficiency improvement activities in our corporate buildings. Energy reduction and other efforts in the Human Resource Development Center were recognized as highly efficient eco-friendly measures, leading us to win the Grand Prize at the Korea Ecological Architecture and Environment Award 2018 in the Architecture Section.
