- The increase is due to a temporary shutdown of on-site steam-generating equipment at the Cambridge site, during which Biogen purchased steam externally to meet operational needs.
- Scope 3 Categories 10, 11, 13, 14 and 15 were determined to be not applicable or negligible.
- The metric reflects data from 90% of top suppliers; emissions increased due to higher spend driven by business priorities.
- The increase is due to an increase in emissions from air transportation.
- The increase is due to the expansion of the Early Access Program, requiring greater product distribution to reach more patients.
- This metric represents our top 80% of suppliers by 2025 spend and is inclusive of near- and long-term targets.
- Energy Attribute Certificates (EACs) are used to claim use of renewable electricity. The decrease in Power Purchase Agreement (PPA) reflects Cambridge’s transition from a PPA to Renewable Energy Certificates (RECs).
- RECs retired include bundled and unbundled EACs, including Green-e certified Renewable Energy Certifications, Guarantees of Origin, J-Credits, Australian RECs and I-RECs to match Biogen’s electricity usage in the U.S./Canada, Europe, Japan, Australia and other global affiliate locations, respectively.
- Because we are a member of RE100, our 100% renewable energy goal covers our imported electricity, which we continue to maintain through acquiring EACs. We take a global approach to calculating the percentage of electricity consumed by our global operations matched by aquiring EACs. We aim to procure EACs in the same grids where we consume electricity. In certain cases, we may procure renewable energy in other locations. The residual emissions from these regions represent 0.07% of Global Renewable Electricity.
- This metric represents our top 50% of suppliers by 2025 spend.
- This metric represents the amount of water reused/recycled, comprised of reclaimed water on-site, harvested rainwater and municipal gray water, as a portion of total water use.
- The reduction in freshwater withdrawal and discharge was largely attributable to the transition of operations from Biogen’s Weston, Massachusetts, site.
- All waste disposal methods are covered in these metrics; no waste is disposed of by other methods. Data include non-hazardous waste generated by Biogen operations (e.g., non-hazardous solid waste and trucked off wastewater). Waste derived from construction and demolition debris, incinerator ash and other contractor activities is not included.
- The increase in waste reused was driven by the closure of Biogen’s Weston, Massachusetts, site and the donation of furniture from sites in Weston, Massachusetts, and Cambridge, Massachusetts.
- See the Environment section for details on the increase in composting.
- This metric represents food waste diverted to anaerobic digestion, a process that converts food waste into renewable biogas.
- Biogen uses both co-processing programs and non-hazardous waste with energy recovery, which is generated by incineration.
- This metric represents the percentage of total non--hazardous waste generated that is diverted from waste-to-energy, incineration or landfill through reuse, recycling, composting and anaerobic digestion.
- Total hazardous and biohazardous waste increased as a result of continued enhancements to our data collection and categorization processes.
- Corporate giving includes global medical grants and patient education grants, general grants, infrastructure grants, donations, in-kind donations, fellowships and sponsorships.
- Includes grants awarded by the Biogen Foundation exclusive of the Foundation’s Employee Matching Gifts Program.
- Employee Matching Gifts consists of Foundation giving through 1:1 and 2:1 donation campaigns.
- Includes data covering all permanent global employees and is adjusted for the number of women and men at each level within the organization and within the same country, for base compensation only. Permanent employees include total employees and exclude limited-term contractors and educational employees/interns. The pay ratio is calculated by averaging the mean base pay for women to mean base pay for men within the same country and level.
