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. Biodiversity Biodiversity describes the variety of life that keeps nature’s ecosystems 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. Circular Economy A circular economy is one in which virgin raw materials, waste, energy, and emissions are minimized through intelligent design, renewable and recycled inputs, energy-efficient production, and enabling the recyclability of products at the end of their life cycles. We are committed to supporting the global transformation to a circular economy. 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 our greenhouse gas emissions in line with the most stringent standard, designed to limit global warming to 1.5 degrees Celsius. We also have a target to reduce our Scope 3 emissions, representing emissions from our supply chain. Inclusion & Diversity We aim to foster an environment which represents people with various racial, ethnic, gender, religious, language, socioeconomic, family and cultural backgrounds, as well as people with different lived experiences, lifestyles, and interests, engaged and working together to create a fair, healthy, and high-performing organization. Inclusion enables employees to feel valued, understood, and inspired to bring their whole selves to work. Living Safely As a company, we are committed to promoting safety for all. We believe that all accidents are preventable, at work and at home. Product Innovation & Stewardship We work to utilize innovation and the principles of product stewardship to ensure that our products are fundamentally safe and sustainable in their design, creation, use, and eventual disposal. We also seek to drive continual improvement in the sustainability of the products we offer, both in their creation and in their ability to help the world meet its sustainability needs. Responsible Water Sourcing & 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.
