Nature-based solutions Industrial-process emissions reductions Protecting nature is one of the strongest Traditional building insulation is applied using a high emissions spray foam which defenses against climate change and by release hydrofluorocarbons (HFCs), a very potent class of greenhouse gases. This conserving and restoring habitats, we are project supports the voluntary transition from spray-foam insulation to low- also preserving biodiversity. Our portfolio emitting board stock, which prevents HFCs from entering the atmosphere. includes integrated forest management and reforestation projects in the US and the Rimba Raya Biodiversity Reserve REDD+ project in Indonesia. Clean cooking and water technology In parts of the world without access to safe drinking water or efficient and affordable cooking technology, women and children are largely responsible for collecting fuel to cook and boil water. When the fuel is burned, it releases smoke and emissions. In 2022, we supported clean cookstove and water- filtration projects in Guatemala, Ghana and Bangladesh. This not only reduces emissions but improves indoor air quality and allows individuals to spend less time collecting fuel and water. Overview Environment Social Governance Appendix 2022 ESG REPORT 14
