In 2024, Biogen reported total carbon emissions of approximately 324,178,000 kg CO2e, with significant contributions from Scope 1, 2, and 3 emissions. Specifically, Scope 1 emissions accounted for about 56,611,000 kg CO2e, while Scope 2 emissions were approximately 507,000 kg CO2e (market-based) and 32,858,000 kg CO2e (location-based). The majority of emissions stemmed from Scope 3, totalling around 267,059,000 kg CO2e, which includes categories such as purchased goods and services (approximately 184,441,000 kg CO2e) and business travel (about 18,067,000 kg CO2e). Biogen has set ambitious climate commitments, aiming for a 55% reduction in absolute Scope 1 and 2 emissions by 2032 from a 2019 baseline. Furthermore, the company is working towards achieving net-zero emissions across its entire value chain by 2045. This includes a long-term goal of eliminating Scope 1 and 2 emissions entirely by 2040 and reducing Scope 3 emissions by 90% by 2045. These targets align with the Science Based Targets initiative (SBTi) and reflect Biogen's commitment to sustainable practices within the pharmaceutical and biotechnology sector.
