10 years of 100% renewable electricity via VPPAs, hydropower PPAs and RECs Biogen has sourced 100% renewable electricity in all markets where it operates since 2014 and joined RE100 in 2015. In 2020 it added multi-year direct hydropower contracts for Cambridge, MA and Solothurn, Switzerland. In 2024 its first Virtual Power Purchase Agreement (Liberty Solar, Texas, ~100 MW total with Biogen taking a 20 MW position) came online, and Biogen signed two additional VPPAs expected operational by 2027. Once all three VPPAs are operational they are expected to cover 100% of Biogen's North America electricity use. Renewable electricity is currently maintained through bundled and unbundled Energy Attribute Certificates (Green-e RECs, Guarantees of Origin, J-Credits, I-RECs).

Biochar-based durable removals via Puro.earth CORC credits To address residual emissions and achieve net-zero market-based Scope 2 emissions, Biogen invested in permanent carbon removals via biochar projects. Biochar is a charcoal-like material created by burning carbon-rich biomass in a low-oxygen environment. In 2024 Biogen retired 45 tCO2e of Puro.earth-certified CORC 100+ credits to offset municipal steam emissions. This is explicitly distinguished as durable removals rather than avoidance offsets.
