2021 Owens Corning Sustainability Report | Our Approach | UN SDG Alignment | 43 MATERIAL TOPIC EXPLANATION 2030 GOALS MOST RELEVANT SDGs AIR QUALITY MANAGEMENT As a manufacturer, we have the opportunity to improve our processes and, in doing so, reduce our impact on air quality in the areas where we operate. Reduce the aggregate intensity of our emissions of volatile organic compounds (VOCs) and fine particulate matter (PM2.5) by 50%. COMBATING CLIMATE CHANGE Owens Corning understands the importance of climate action, and we take our role in the fight against climate change seriously. We have embraced a science-based target for greenhouse gas emissions in line with the most stringent standard, designed to limit global warming to 1.5° Celsius. We also have a target to reduce our Scope 3 emissions, in line with well below the two degrees Celsius methodology, representing emissions from our supply chain. Achieve 50% reduction in absolute Scope 1 and Scope 2 greenhouse gas emissions from the 2018 baseline, in line with what is needed to limit global warming to 1.5° C. Our target has been validated and approved by the Science-Based Target Initiative. We also have a goal to reduce absolute Scope 3 emissions by 30%. WASTE MANAGEMENT Our ambition is to mitigate the waste that we produce by redesigning the process to avoid its creation, then repurposing it whenever possible. We are committed to redefining waste, continuously looking for beneficial uses for our byproducts and other waste materials. Send zero waste to landfill by cutting the amount of waste we generate in half and recycling the rest. ENERGY EFFICIENCY AND SOURCING RENEWABLE ENERGY We are determined to continue decreasing our dependence on fossil fuels, both by improving efficiency in our operations and by meeting more of our energy demands through renewable sources. Source 100% renewable electricity. Switching to 100% renewable electricity and purchasing energy from renewable sources are essential to our effort to halve our greenhouse gas emissions. We will also work to reduce emissions from our processes and improve energy efficiency. This will put us on the path to eventually eliminating our use of fossil fuels. RESPONSIBLE WATER SOURCING AND CONSUMPTION We are committed to using water in an intelligent, sustainable way across the company. We operate in a number of different regions across the world, some of which are in areas of higher water stress than others. Through reuse, recycling, and efficiency, we strive to consume less water in our operations. We also must understand where our water use is most impactful, to set informed targets for water reduction. Cut in half the amount we take from the local water supply in places where water is limited in quantity or quality, while other facilities remain at the same water intensity as our base year of 2018 or lower when aggregated. PROTECTING BIODIVERSITY Biodiversity describes the variety of life that keep nature’s ecosystem in balance. Owens Corning is committed to preserving and enhancing biodiversity and the natural habitats that surround our operations around the world. We seek to understand and manage the biodiversity impact of all our own operations, as well as gain insights into the impacts of our supply chain on biodiversity. Develop biodiversity goals based on an understanding of the full impact of our operations and supply chain on biodiversity by 2025. REDUCING OUR ENVIRONMENTAL FOOTPRINT Guiding Aspiration: Cut the negative impact of our operations in half.
