Carbon Emissions

Carbon Emissions Reduction Management Policy

SK discovery and subsidiaries proactively respond to climate change to help long-term sustainability. We are working to reduce Scope 1 emissions generated by direct energy sources in our business sites and buildings. At the same time, in line with government policies, we are promoting effective carbon reduction while minimizing the impact of changes in energy policy at home and abroad.

In addition, we are striving to reduce carbon emissions in a variety of ways, including: constructing eco-friendly buildings, transitioning to green energy sources, incinerating waste, using biomass and utilizing waste heat from neighboring factories. In order to manage carbon emissions and systematically operate business, our managers in charge of this task at each site regularly monitor carbon emissions.

SBTi 기반 Net Zero Roadmap

SK디스커버리는 기후변화 문제에 적극적으로 대응하고 지속 가능한 사회로의 전환을 앞당기기 위해 2035년 Net Zero 목표를 수립하였습니다. SK디스커버리는 지구의 기온 상승을 1.5℃로 제한하기 위한 파리협약의 목표를 지지하고 이에 협력하고자 과학기반 감축목표 이니셔티브인 SBTi(Science Based Target Initiative) 권고안에 따라 Net Zero Roadmap을 수립하였습니다.

SK디스커버리의 온실가스 배출량은 기준연도인 2021년 기준 49,653 tCO2e이며, 이 중 57%인 28,494 tCO2e가 Scope 1, 43%인 21,159 tCO2e가 Scope 2에서 발생하였습니다.

SK디스커버리는 SBTi 방법론에 따라 2030년을 Near-term Target으로 설정하였으며 연평균 14%의 온실가스 배출량을 감축해 나갈 계획입니다. 2030년 이후에도 온실가스 감축을 위한 노력을 지속하여 2035년 Net Zero 목표를 달성하고자 합니다.
