2021 Owens Corning Sustainability Report | Reducing Our Environmental Footprint | Combating Climate Change | 154 Scope 3 Emissions Recognizing the variety of activities both upstream and downstream of our operations, we follow multiple approaches to determine the amount of GHG emissions generated throughout our value chain. In 2021, our Scope 3 emissions totaled 3,345,559 metric tons of CO 2 e. More information about emissions across our value chain can be found on page 315 in Appendix C. We have reduced absolute Scope 1 and Scope 2 CO 2 e emissions by approximately By cutting those emissions in half over the next decade, our 2030 absolute Scope 1 and Scope 2 CO 2 e emissions will be approximately since our peak emissions year of 2007. 60% 75% lower than the peak emissions year of 2007. 2021 Scope 3 GHG Emissions  Purchased goods and services ^ 48%  Capital goods + 3%  Fuel- and energy-related activities (not included in Scope 1 or 2) ^ 12%  Upstream transportation and distribution ^ 4%  Business travel ^ <1%  Employee commuting ^ 1%  Downstream transportation and distribution ^ 12%  Processing of sold products + 14%  End of life treatment of sold products ^ 7% ^ Assured to a high level by SCS Global Services + Assured to a moderate level by SCS Global Services Photo submitted by: Abigail Sprague | Wabash, Indiana, U.S. Sunrise at the Wabash plant.
