Water/Energy Efficiency

SK discovery and subsidiaries strive to improve the efficient use of resources in production and procurement. This allows us to build a business model with a harmonious ecosystem and more stakeholders that creates both economic and social values.

Water Risk Assessment

SK chemicals actively responds to long-term water risks. These risks are twofold: “Physical water stress,” based on the intensive use of water for product development; and “water quality risk,” which can result from chemical emissions, such as catalysts. We rely on the World Resources Institute Aqueduct tool* to analyze and manage water risk exposures.

Water and Wastewater Management Policy

While ample water resources are essential for plant production and operation, using water resources also carries the risks of natural disasters, such as drought and floods. In response to such possible climate disasters, our subsidiaries are continuously identifying and applying measures to reuse and recycle water.

We continue to save water by reusing some water that was previously discarded after use.

Energy Management Policy

While interest in green energy is rising fast, the world remains heavily dependent on fossil fuels. To help reduce that energy use, SK discovery manages subsidiary usage and progress by streamlining their operations. Recognizing the importance of reducing greenhouse gases and improving operational efficiencies, we incorporate sustainability and environmental impact factors into the decision-making processes of our investment and business expansion.

Energy Consumption

SK디스커버리 및 멤버사가 보유한 유형자산을 활용한 재생에너지 자가발전과 재생에너지로 생산한 전력 구매를 통해 재생에너지를 사용하고 있습니다. 지속적으로 재생에너지 사용을 확대하기 위해 자가 발전량을 높이고, 신재생에너지 관련 투자를 늘려 나갈 계획입니다.
