2021 Owens Corning Sustainability Report | Reducing Our Environmental Footprint | Energy Efficiency | 139 Our Energy Roadmap Owens Corning’s plan to increase energy efficiency and source renewable electricity includes the following strategies: Short-term Strategies ■ Increase renewable electricity consumption across the grid through additional wind Virtual Power Purchase Agreements (VPPAs) in Sweden and Finland. ■ Continue reducing the energy intensity of our operations through energy efficiency projects. Medium-term Strategies ■ Consider additional renewable energy opportunities on a global basis, including longer-term agreements, and consider PPAs in the other regions where we operate, such as Latin America and Asia Pacific. ■ Drive continued electrification of processes where feasible to reduce fossil fuel usage. ■ Through projects and sourcing, switch to 100% renewable electricity and improve energy efficiency by 20% by 2030. Long-term Strategies ■ Drive innovation within our research and development portfolio to enable further conversion from fossil fuels to carbon neutral and renewable energy to power our processes. ■ Explore new renewable fuel technologies and opportunities, working towards an aspiration of using 100% renewable energy. Outreach and Accountability Owens Corning ensures accountability and encourages further progress toward our sustainability goals. ■ We believe that rewarding our employees for their dedication to sustainability is essential, and we recognize teams that help us meet our energy goals with companywide performance awards. In addition, sustainability goals are a factor in incentive compensation for our management team. For example, we incentivize our composites energy teams with cash rewards and recognition. ■ Owens Corning partners with over 250 like-minded organizations in the U.S. Department of Energy’s Better Plants Program, which provides our energy leaders with tools, training and technical assistance. In addition, we have expanded our commitment to this program by entering the Better Plants Challenge described on page 141. ■ We use a number of external platforms, including our website and this sustainability report, to publicly disclose our environmental performance. We invite comments and feedback from all our stakeholders. Power Purchase Agreements To expand our renewable energy platform, we have entered long-term power purchase agreements (PPAs), which support the development of large renewable energy projects. The PPAs signed in 2015 enabled wind capacity in Texas and Oklahoma, with the potential to generate 1.1 million megawatt hours (MWh) of electricity each year, from a capacity of 250 megawatts (MW) of renewable electricity. This includes 125 MW of wind energy in Texas and another 125 MW in Oklahoma. Owens Corning aspires to have contracts in place covering 75% of our global enterprise electricity demand through renewable agreements which will drive additionality to the grid over the next two years. Within the United States today, for every MWh of electricity generated by the renewable installation, we receive one energy attribute certificate (EAC), which we then apply to the manufacturing of our products. We retire all the EACs generated from our PPAs, which reduce our environmental footprint and the embodied carbon of our products. While it’s possible for a company to reduce its footprint simply by purchasing EACs, Owens Corning believes that we should also be directly responsible for bringing more renewable electricity into the grid through power purchase agreements or virtual power purchase agreements (VPPAs). The (VPPAs) that Owens Corning entered in 2021 will add 91 MW of renewable capacity to the grid. We have entered into two wind VPPAs, one in Finland and one in Sweden, which will bring in 43 MW and 48 MW of renewable electricity capacity, respectively. The VPPA in Sweden reached its commercial date of operation in 2021, while the VPPAs in Finland will reach its commercial date of operation in 2022.
