2021 Owens Corning Sustainability Report | Our Approach | UN SDG Alignment | 42 MATERIAL TOPIC EXPLANATION 2030 GOALS MOST RELEVANT SDGs CIRCULAR ECONOMY A circular economy is one in which virgin raw materials, waste, energy, and emissions are minimized through intelligent design, renewable and recyclable input, energy- efficient production, and enabling the recycling of products at the end of their life cycles. We are committed to supporting the global transformation to a circular economy. Establish viable circular economy business models involving our materials and how they are used by collaborating up and down the supply chain with customers, suppliers, communities, academics, policy makers, government entities, and other organizations. Increase recycled content and decrease virgin raw materials used in our products. Develop technical solutions and practical business models for our product materials and packaging to continuously be used for beneficial purposes even after they are no longer used for the original purpose. PRODUCT INNOVATION & STEWARDSHIP We work to utilize innovation in the principles of product stewardship to ensure that our products are fundamentally safe and sustainable in their design, creation, use, and eventual end of life. We also seek to drive continuous improvement in the sustainability of the products we offer, both in their creation and in their ability to help the world meet its sustainability needs. Offer the most recognized and preferred products for sustainability. SUPPLY CHAIN SUSTAINABILITY We strive to hold our suppliers to the same high standards we hold ourselves. We see our suppliers as a key contributor to our overall sustainability vision and seek to ensure all our suppliers fully comply with all applicable legislation, regulations, and legal requirements on human rights, labor, the environment, anti-corruption, and trade and customs. Collaborate with suppliers to increase transparency around the raw materials we use in our products. Reduce the greenhouse gas emissions related to our purchased materials and services by collaborating with our suppliers to cut these emissions by 30%. Our target has been validating and approved by the Science-Based Target Initiative. 100% of our global sourcing team will be trained and recertified annually of sustainability.
