2021 Owens Corning Sustainability Report | Reducing Our Environmental Footprint | Energy Efficiency | 138 By 2030, we will be sourcing 100% renewable electricity. Purchasing electricity only from renewable sources is a key part of our effort to halve our greenhouse gas emissions. We’ll also work to reduce the emissions from our processes and improve energy efficiency. We will also reduce energy use by 20% over our baseline year. Over our goal cycle, we will work to reduce energy use from both renewable and non-renewable electricity, as well as other forms of non-renewable energy* by 20% from our baseline year of 2018. These two approaches — along with fuel switching and low-carbon or no-carbon fuels and technologies — will put us on the path to eventually eliminating our use of fossil fuels. * Non-renewable energy includes, but is not limited to, natural gas, fuel oil, gasoline, diesel, propane, and LPG. 2030 GOALS FOR ENERGY EFFICIENCY & SOURCING RENEWABLE ENERGY OUR APPROACH In support of the 2030 goals described above, Owens Corning has identified a number of other approaches to help us achieve our 2030 goal for energy efficiency and the sourcing of renewable energy. Other strategies that will help us achieve our overarching goals for energy can be found in our Combating Climate Change chapter . Tracking and Monitoring Our Performance Owens Corning has robust systems in place to track and monitor our performance against key energy-related indicators. Each month, our plants report performance on our goals and targets, which helps us stay current on data and spot variations that may require corrective action. Across our network of plants, designated energy leaders oversee the implementation of energy management activities and help identify areas for improvement. In addition, Owens Corning has energy managers who conduct assessments, facilitate Kaizen and Total Productive Maintenance activities, develop projects, and provide technical support. Several plants with medium and high energy usage also have energy teams that meet monthly. 2030 Energy Efficiency (MWh) GOAL: 20% REDUCTION 2030 Renewable Electricity GOAL: 100% R ENEWABLE 51% 2021 201 8 BASE YEAR 48% 50% 2019 52% 2020 2% 10,499,961 2021 201 8 BASE YEAR 10,719,236 4% 10,274,193 2019 10% 9,658,731 2020
