2021 Owens Corning Sustainability Report | Overview | Introduction | 3 BUILDING A SUSTAINABLE FUTURE Thank you for your interest in Owens Corning and the sustainability efforts that are at the heart of our operations. This is our 16th annual report, and we hope you find it to be a valuable resource in understanding our all-encompassing approach to sustainability. Our theme this year is inspired by Owens Corning’s refreshed mission statement, which was adopted in 2021: Building a sustainable future through material innovation. Throughout this report, we demonstrate how we are working to fulfill that mission, as well as the many ways our people and our products are helping make the world a better place. Our emphasis on a sustainable future is especially appropriate this year, as this is the first report to be completely focused on our 2030 sustainability goals. This ambitious slate of objectives underscores our aspiration to be a net-positive company, one whose positive impacts far outweigh any negative impacts. Our sustainability goals are built on three key pillars: ■ Expanding our product handprint. We endeavor to increase the positive impacts our products have on the world. ■ Reducing our environmental footprint. We seek to limit the negative impact our operations have on the environment. ■ Increasing our social handprint . We work to safeguard people’s safety and help ensure that they live with health, happiness, and human dignity. The report is structured around 16 Sustainability Materiality Topics, which our stakeholders have indicated are most meaningful to them, and we have arranged the topics based on their relevance to these three pillars. We have prepared this report in accordance with the Global Reporting Initiatives (GRI) Comprehensive option. This is the more extensive option for GRI reporting, requiring additional disclosure related to our strategy, ethics and integrity, and governance. This report has been independently verified, including data and descriptions of all the ways our commitment to sustainability manifests itself. The chapters include explanations of our overall approach to each material topic, descriptions of the various initiatives we have in place to achieve our goals, and overviews of our progress to date. Additional supporting data can be found in the appendices at the end of the report, as well as indices reflecting information in response to the GRI standards, the United Nations Global Compacts (UNGC), Advanced- Level Communication on Progress, the Task Force on Climate-related Financial Disclosures (TCFD) and the Sustainability Accounting Standards Board (SASB) reporting requirements. Throughout the report, we also spotlight some of the employees who are helping to drive our efforts in each of our material topics. These Speaking of Sustainability interviews reveal the personal side of our endeavors and underscore the idea that our work in general — and our sustainability goals in particular — are global in scope and human in scale. Owens Corning is building a more sustainable future on a solid foundation, one that is based on years of successful innovation and dedication to our goals. As we continue to make progress on a new slate of goals — our most ambitious to date — we hope you will be inspired to join us on our sustainability journey.
