2021 Owens Corning Sustainability Report | Appendices | 339 UN GLOBAL COMPACT COMMUNICATION ON PROGRESS Appendix E The progress we have made on our sustainability journey serves as a baseline for our next steps. We are currently working toward an ambitious slate of 2030 sustainability goals, which will require us to innovate and collaborate among all stakeholders as we work to make a difference in the world. In one key example, we have set a target to reduce greenhouse gas emissions to the levels needed to limit global warming to 1.5° Celsius — a target that has been approved by the Science Based Targets initiative. In addition, we are implementing contextual water use targets based on the WRI Aqueduct Indicators that address the risks to water supply in high water-stress areas. This year we also completed two power purchase agreements for renewable energy around the world. The full story of our 2030 sustainability goals — and our ongoing efforts to achieve them — in the attached report demonstrates our progress and current efforts in areas related to the 10 principles of the Global Compact. An index highlighting the relevant sections in the report is also included. We are proud of what we have achieved in pursuit of our sustainability goals, even as we acknowledge that every accomplishment represents an opportunity upon which to build. It is in this spirit that I, on behalf of everyone at Owens Corning, reaffirm our commitment to the Global Compact and our dedication to conducting business responsibly throughout the world.
