2021 Owens Corning Sustainability Report | Overview | Summary & Highlights | 20 Supply Chain Sustainability By 2030, 100% of our suppliers will meet our Supplier Code of Conduct requirements, with special attention to human rights issues such as safety and forced labor. We will continue to prioritize supply chain partners that share our commitment to sustainability in all its forms. In line with the Supplier Code of Conduct, in 2021, 100% of new suppliers were evaluated for a range of criteria, including environmental and social factors (e.g., human rights and labor practices). In 2021, Owens Corning enhanced our approach to prioritizing suppliers, empowering us to further emphasize the importance of sustainability throughout our value chain. This approach provides additional consideration of our suppliers’ environmental, social, and governance (ESG) risk exposures. The environmental, social, and governance risk scoring framework is based on S&P Global Rating’s ESG Risk Atlas. A sector risk score, which encompasses associated environmental and social risk rationales, is assigned based on the supplier’s commodity. A regional risk score, which embodies governance rationales, is assigned to a supplier’s country. The overall ESG Risk Score is then tallied for each supplier by adding the 3 E, S, and G risk scores. For suppliers who provide multiple commodities to Owens Corning, and therefore potentially have multiple ESG risk scores, we selected the highest ESG risk score to conservatively represent these suppliers.
