2021 Owens Corning Sustainability Report | Expanding Our Product Handprint | Supply Chain Sustainability | 123 2030 GOALS FOR 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. As we discuss in the Combating Climate Change chapter , we have a 2030 goal to reduce absolute Scope 3 emissions — indirect greenhouse gas emissions such as those from our supply chain — by 30%. + Our suppliers will play an active role in achieving this goal. More information about our progress toward this goal can be found beginning on page 154. OUR APPROACH Owens Corning uses a variety of materials, including minerals, chemicals, energy, and packaging to manufacture our range of products. Our global manufacturing facilities perform processes that convert raw material inputs into finished products (or, in the case of composites, finished input materials to be used by another business). With operations in 33 countries, we manage inbound and outbound freight transport via truck, ship, and rail. Most of our supply spend goes toward material suppliers, with the next greatest amount going to transportation companies. In addition, we work with distributors and service suppliers for capital goods, machinery, and myriad technical, consultative, and management services. Our total base of suppliers consists of more than 19,000 organizations with an approximately $6.5 billion spend. We have active management processes in place to evaluate, segment, and engage with all top- spend suppliers. Through our segmentation process, 775 vendors comprise 74% of our sourcing managed spend. We determine appropriate action items related to each supplier based on the supplier’s specific profile, as described in the Management of Suppliers and Risk section later in this chapter.
