2021 Owens Corning Sustainability Report | Our Approach | UN SDG Alignment | 49 SDG Target 12.5 | By 2030 substantially reduce waste generation through prevention, reduction, recycling and reuse. Our goal is to send zero waste to landfill by 2030. We have a two-part plan to achieve this. First, we aim to reduce waste intensity by 50% through improvements to efficiency and process design. We will then repurpose or recycle the remaining waste. In 2021, we achieved a 17% reduction in waste/byproducts generated over the base year of 2018, and a 62% overall waste diversion rate compared to 2018. SDG Target 12.6 | Encourage companies, especially large and transnational companies to adopt sustainable practices and to integrate sustainability information into their reporting cycle. We disclose sustainability performance on a number of different platforms. Due to timing and data collection requirements, we have not yet published simultaneous financial and sustainability reports, but we are considering what we would need to do to make that possible. SDG Target 12.7 | Promote public procurement practices that are sustainable in accordance with national policies and priorities. We believe suppliers are critical partners in our sustainability efforts. We discuss our commitments, goals, and expectations in the Supply Chain Sustainability chapter in this report. Climate Change To reduce the impact of our operations and activities on global climate change, we focus on accelerating energy efficiency improvements, renewable energy deployment, and greenhouse gas (GHG) emission reductions. SDG Target 13.1 | Strengthen resilience and adaptive capacity to climate related hazards and natural disasters in all countries. We participate with builders, architects, and engineers to provide technical information and product innovations for resilience in building construction and infrastructure. We work with industry associations and consortia to advance understanding of how our materials help combat the effects of climate change — and help support quality of life as people face climate- related challenges. In consultation with experts in the field, Owens Corning began work with The Ohio State University in 2020 to expand our efforts to assess the resilience of our strategies against a range of climate-related scenarios and time horizons. These scenarios will focus on risks and opportunities globally and at business level. SDG Target 13.3 | Improved education, awareness raising and human and institutional capacity on climate change mitigation, adaptation, impact reduction and early warning. We provide education throughout the company. Our 2021 Sustainability Summit featured presentations on our sustainability strategies regarding our product handprint and environmental footprint, the circular economy model, embodied carbon, healthy living strategies, inclusion and diversity ambitions and metrics, employee engagement, and safety. Partnerships for the Goals Collaboration within our supply chain is key to meeting our ambitious 2030 goals. It will require the participation of every stakeholder in our value chain, from suppliers to customers and end users, as well as policymakers, external researchers, and many others. SDG Target 17.3 | Mobilize additional financial resources for developing countries from multiple sources. In 2021, Owens Corning and the Owens Corning Foundation distributed over $5 million in cash contributions to nonprofit organizations. A portion of this funding was used for the OC Cares Fund, which is managed by an independent nonprofit. For details about our community engagement initiatives, please see our Community Engagement chapter. SDG Target 17.6 | Enhance North-South, South-South and triangular regional and international cooperation on and access to science, technology and innovation and enhance knowledge sharing on mutually agreed terms, including through improved coordination among existing mechanisms, in particular at the United Nations level, and through a global technology facilitation mechanism. SDG Target 17.16 | Enhance the global partnership for sustainable development, complemented by multi-stakeholder partnerships that mobilize and share knowledge, expertise, technology and financial resources, to support the achievement of the sustainable development goals in all countries, in particular developing countries.
