2021 Owens Corning Sustainability Report | Reducing Our Environmental Footprint | Combating Climate Change | 147 By 2030, our goal is a 50% reduction in absolute Scope 1 and Scope 2 market-based greenhouse gas emissions from the base year of 2018. ■ Scope 1 refers to the direct emissions from our own manufacturing operations. ■ Scope 2 refers to indirect emissions from the generation of purchased energy. 2030 GOALS FOR COMBATING CLIMATE CHANGE Owens Corning has reduced absolute Scope 1 and Scope 2 GHG emissions by 12% from the 2018 base year, in part due to efforts related to our renewable energy strategy as well as energy efficiency and process improvements. Our increase in metric tons of GHG emissions in 2021 was driven by a large increase in production. We also have a goal to reduce absolute Scope 3 emissions by 30%. ■ Scope 3 refers to other indirect emissions, primarily those from our supply chain. OUR APPROACH In our Climate Change Statement, we acknowledge the following points: ■ Both governments and businesses worldwide are expressing widespread support for the scientific findings regarding human activity’s impact on climate change. ■ There is a need for us to reduce energy use, water use, and greenhouse gas emissions as part of our efforts to combat climate change. Recognizing the significant scope of our operations and activities, we include energy and climate change in our risk register. We are committed to accelerating improvements to our energy efficiency and reducing our overall energy use. In addition, we continue to accelerate our shift toward renewable energy. We seek opportunities to expand our portfolio of renewable energy sources and have designated a cross-functional team of internal and external subject matter experts to evaluate all potential opportunities — including both on-site renewable programs and larger off-site installations. Owens Corning has reduced absolute Scope 3 GHG emissions by 8% from the 2018 base year. The reduction in Scope 3 emissions is due primarily to a decrease in emissions from Purchased Goods and Services, the category of emissions which reflects the impact of raw materials and use of recycled content in our products as reflected in our transparency efforts, specifically life cycle assessments.
