OUR PURPOSE PIONEERING SCIENCE COMMUNITY REPORTING 83 ADVANCING HEALTHY CLIMATE, HEALTHY LIVES™ BIOGEN 2021 YEAR IN REVIEW PATIENTS OUR PEOPLE ENVIRONMENT Collaborating with suppliers Responsible supply chain and procurement We are building on our near-term supplier engagement goals with ongoing efforts to develop a robust responsible sourcing program, and we established a Steering Committee to advise on sustainable sourcing. We are developing a process for evaluating supplier ESG risk against our maturity model and plan to begin direct engagement with key suppliers to accelerate their transition to renewable energy, transparent ESG reporting and science-based targets. Þ READ MORE ABOUT OUR RESPONSIBLE SUPPLIER PROGRAM We recognize that there are significant opportunities yet to be realized and are committed to progress. Advancing net zero supply chain goals Our supply chain accounts for more than 85% of Biogen’s greenhouse gas (GHG) emissions, and we have set net zero supplier targets, which are pending approval by the Science Based Targets initiative ( See “program progress” chart ). At COP26, Biogen was one of 10 global pharmaceutical and biotech companies to launch Energize, a new program to increase access to renewable energy for the sector’s supply chain. A program initiated by Schneider Electric and Carnstone, Energize includes AstraZeneca, GSK, Johnson & Johnson, Merck, Novartis, Novo Nordisk, Pfizer, Sanofi and Takeda, alongside Biogen. Together, we aim to work toward value chain decarbonization. Through Energize, pharmaceutical suppliers have the opportunity to learn more about the renewable energy market, receive guidance on power purchase agreements (PPAs) and access and contract for renewable energy. In January 2022, Biogen became one of the inaugural customers for United Airlines Eco-Skies Alliance program and for JetBlue’s Sustainable Travel Partners Program . These partnerships enable Biogen to reduce business travel emissions and provide a customized analysis for more accurate emissions reporting and tools for planning and target setting to support more sustainable travel decisions. SPOTLIGHT Carbon-Free Challenge: Japan reduces CO 2 emissions by 3.2 tons In 2021, Biogen’s Japanese affiliate launched a Carbon-Free Challenge to see how much carbon emissions they could reduce in April, which is Earth Month. They began with a virtual discussion on how making small changes to their habits and behaviors could make a big impact for the environment. More than 150 employees got involved, deciding to walk instead of taking a bus, eliminating single-use plastics and eating a lower-carbon diet, as examples. By the end of the Carbon-Free Challenge, employees reduced their combined carbon emissions by 3.2 tons, the same amount of carbon captured by 50 trees over 10 years. If participating employees maintain their new habits, it could reduce 38 tons of carbon in one year – equivalent to providing energy for about 15 houses annually. For this work, Biogen Japan won the Top Sustainability Advocate in Asia Award from the Asian Corporate Excellence and Sustainability Awards. Grew our electric vehicle program to 12 COUNTRIES
