2021 Owens Corning Sustainability Report | Overview | Our Sustainability Aspirations | 15 Top Areas of Focus The work we’re doing toward our 2030 sustainability goals is described in more detail in the chapters of this report. There are several key areas of work that will support the goals. In some cases, multiple goals will be affected by one focus area. Accountability for progress on these critical priorities rests with our top business executives, ensuring broad engagement across the company in our sustainability work. These 11 areas represent a wide range of projects, initiatives, and opportunities for Owens Corning — our progress toward these priorities is chronicled in this report. Blowing agent. Solve the technical, business, and commercial puzzles in both our global foam insulation operations and our products to eliminate blowing agents that have high global warming potential.
