2021 Owens Corning Sustainability Report | Expanding Our Product Handprint | Supply Chain Sustainability | 132 SPEAKING OF SUSTAINABILITY Born in Taiwan and raised in Malaysia, Jelling Lai grew up immersed in island environments, and the natural beauty of those places inspired her to pursue sustainability as a career. That passion led to degrees in environmental science, chemistry, and environmental policy, as well as two MBAs. Jelling brings this science-based focus to Owens Corning as sustainability standards and compliance leader for our global sourcing and supply chain. Her background gives her a unique perspective on the ways corporate responsibility and business imperatives intersect, as well as how Owens Corning’s supply chain touches all aspects of our efforts to increase our product handprint.

The landscape is very new as companies out there are trying to figure out the how we materialize sustainability within our own footprint and within our entire value chain. I think this then alludes to the circular economy model where we really engage suppliers in terms of end of life solutions and our ability to recycle or reuse some of the things we have manufactured. The landscape is emerging; as companies figure out how to materialize sustainability within the entire value chain, circular economy and end of life solutions are essential elements to enable our journey toward a more sustainable future. On the role our suppliers play in our sustainability efforts Our suppliers are critical partners in our sustainability journey in that their Scope 1 and 2 emissions translate into our Scope 3 emissions — and that’s just one facet. It’s really important that we build on these partnerships. For example, by having their greenhouse gas emissions inventoried, we’re able to gain visibility into what their emissions account for them and for ourselves as well. Seeking innovative ways to work together and finding sustainable alternatives are also a part of that journey. An example of that is sourcing alternatives to virgin materials. That’s an area where our sourcing leaders are working hard, looking at what those alternatives will be, and our suppliers are a key part of helping us find those options. On approaching Owens Corning’s goals with confidence We’re taking tangible steps towards achieving the goals we set in front of us, and that assures me about where we’re heading. We also align ourselves to very stringent standards and expectations. We not only align to the U.N. Sustainable Development Goals, but we also have set science-based targets along with other frameworks and standards. We know this is a journey with guidance, guard rails, peer review, and third-party verification. That enhances the robustness of the journey that we have been on. In addition to the rigorous bar we’ve set and will continue to measure ourselves against, I’ve experienced the openness, the curiosity, and the passion of my colleagues to want to discover the new and want to think about what sustainability means in their fields of expertise. That, to me, really fuels the energy and the promise of what we can do. Our suppliers are critical partners in our sustainability journey. ” “ Jelling Lai Sustainability, Standards, and Compliance Leader
