Climate Change

We create a sustainable future where people, society and the environment will coexist.


SK ecoplant’s climate polices are equal to its business strategies. We have recognized that a proper response to climate change is a top priority and have committed to resolving this issue. To this end, we have restructured and transitioned our business model to an environmental business to promote a circular economy, as well as to an energy business for carbon emissions reductions. In 2021, we announced our commitment to achieving our 2040 Net Zero Target, which was a testament to our strong determination to address climate change, as well as developing more detailed plans for attaining the net zero target based on the SBTi methodology and guidelines in 2022. Our net zero implementation plan is disclosed in accordance with the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD). In addition, we have voluntarily participated in the Carbon Disclosure Project (CDP) and achiev grade A- in 2021.
Beginning in 2022, to promote our company-wide net zero commitment, we set up the Net Zero Transition Council in line with the revision of environmental policies and changes to the business environment while establishing reduction targets for greenhouse gas (GHG) emissions and connecting them with KPIs of each organization. In the mid- and long-term, SK ecoplant is planning to transition 30% of our electric power to renewable energy by 2025, gradually increasing this proportion in order to achieve our own RE100 target by 2030.
Furthermore, in 2020, we included climate change as a key risk assessment factor in the process of business model transition. The ESG Promotion Division, the body in charge of climate-related issues at SK ecoplant, identifies and manages climate-related risks across our entire operations, including new projects and investments.


SK ecoplant is determined to contribute to the net zero commitment by transitioning to an environmental-friendly enterprise, which will, in turn, lead to the development of infrastructure suitable for supplying and consuming new renewable energy. Having set 2021 as a base year, we established a 2040 Net Zero target and roadmap for all of our domestic business sites and submitted our SBTi target in 2022. Based on the 1.5 ℃ scenario, we aim to reduce Scope 1 and 2 carbon emissions by 42 % by 2030 and 100% by 2040. We are establishing a Scope 3 reduction target and plan that complies with the 2℃ or less scenario.

01. Net Zero Transition Council

SK ecoplant set up the Net Zero Trans Council to create momentum company-wide and expedite decision making and its application for the achievement of the 2040 net zero target. The council, which consists of six business units including SK ecoengineering and three centers, strengthens our net zero management system by holding company-wide monthly meetings and reporting meeting results to the CEO on a quarterly basis. For more efficient energy management, we run environmental efficiency indicators, taking into account the characteristics of each business site while focusing on managing reduction activities for carbon, water, waste and energy. Further, we are involved in a wide variety of reduction activities such as RECs, installing Roof-PV at business sites, participating in the K-EV 100 initiative, and operating a carbon reduction program for employees to purchase low-carbon products.

02. Greenhouse Gas Emissions

To manage Scope 1, 2, and 3 emissions, SK ecoplant began expanding our verification to cover Scope 3 emissions starting in 2021. We verified eleven categories (1, 2, 3, 4, 5, 6, 7, 8, 11, 12, and 15) in total in 2022. Our Environmental Management Information System (EMIS) is linked to the company-wide resource and financial management system to transparently measure greenhouse gas (GHG) emissions. Our emissions in 2021 amounted to 33,242 tons, a slight drop from 33,623 tons in 2020.

03. Employee Carbon Reduction Program

SK ecoplant launched an employee carbon reduction program starting 2022, aiming at reducing 12 kg of carbon emissions per employee annually. They accumulate SV points and participate in emissions reduction by joining various sub-programs, such as Monthly Challenge, and the amount of emissions reduced through their activities are collected in real time. Moreover, the accumulated points are donated to the installation of Solar Cow, a solar charging station for youth in Africa. Other programs to be implemented in the first half of 2022 include Eco-friendly Promise, a Carbon Literacy Course, use of tumblers, low-carbon diet, zero food waste, email diet, and an in-house second-hand market. As of May, 2022, we have reduced 26 tons of carbon emissions in total, or 5.5 kg per employee.

04. Reduction Activities

In March 2022, to achieve our company-wide commitment to Net Zero, we launched a Net Zero Transition Council that consists of executives in every business division. Aimed at reducing GHG emissions in 2022 by 2.75 % or more compared to that of 2021, SK ecoplant is making efforts to improve on-site environmental efficiency indicators, including installation of more than one Roof-PV at each BU site, in order to manage demands for energy as well as facilitating efficient energy operation. Furthermore, the company’s transition to electric vehicles via the K-EV100 initiative contributed to reducing five tons of GHG emissions in 2021 and 3 tons in 2022 (up to March), while the solar power generators installed on the rooftops of our field offices helped reduce 50 tons and 24 tons of emissions in 2021 and 2022 (up to March) respectively. Going forward, we will be continuously engaged in reduction activities, including the purchase of RECs in 2022 to reduce about 700 tons in GHG emissions and the installation of at least 4 solar power generators on the rooftops of field offices to directly reduce about 200 tons in emissions. Further, we aim to manage Scope 3 emissions by establishing a carbon reduction roadmap and purchasing low-carbon products, and are even establishing our subsidiaries’ GHG inventory as part of our efforts to enhance their ESG management.

05. RE100

SK ecoplant used 2.9 GWh of renewable energy in 2021, which included 2.8 GWh of Green Premium and 0.1 GWh of solar power. Renewable energy accounted for about 5% of our total power consumption, and we are planning to increase its proportion to more than 8% in 2022.

Roadmap to 2040 Net Zero

SK ecoplant is preparing for innovation and changes in business and corporate management in order to achieve 2040 Net Zero. We will mitigate greenhouse gas emissions by purchasing RECs, transitioning to pollution-free vehicles (K-EV 100), installing roof-PV, purchasing low-carbon materials, applying CCU and CCUS to incinerators, and building zero-energy buildings with improved energy efficiency. We are pursuing step-by-step mitigation activities to reduce Scope 1 & 2 and Scope 3 GHG emissions by 42% and 17%, respectively, in 2030 compared to 2021, and reach Net Zero by 2040. We plan to verify the short-term and mid- to long-term goals based on the 1.5°C and 2°C degrees GHG mitigation scenarios of the Science-Based Reduction Target Initiative (SBTi), and continue to mitigate and manage GHG emissions accordingly.
