2021 Owens Corning Sustainability Report | Reducing Our Environmental Footprint | Protecting Biodiversity | 197 BIODIVERSITY PERFORMANCE We are still developing our specific goals for protecting biodiversity, and the assessments we are performing are an essential part of that process. Using what we learn here will provide us with the knowledge we need to establish management plans that safeguard species around the world. Integrated Biodiversity Assessment Tool Findings The Integrated Biodiversity Assessment Tool (IBAT) provides us with greater awareness of our proximity to areas with high biodiversity value. As we continue to implement IBAT, we will be able to act with greater transparency. By expanding our biodiversity screenings to include Key Biodiversity Areas, we see where the potential for adverse impact exists if left unchecked, which in turn gives us cause to explore further. As our understanding grows, we are committed to developing management plans to mitigate our impact on species in the areas where we operate. The chart below contains information derived from the Biodiversity Management Plan, which is discussed on page 191. Sites within a KBA’s boundaries receive priority for mitigating action.
