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.
