In 2025, Biogen consumed a total of 1.61 million Gigajoules of energy across its operations. Of this total, 31.53% was sourced from renewable energy, either derived from natural resources like biofuels, biomass, or biogas, or generated using renewable technologies such as solar or wind power. The remaining 68.47% was classified as non-renewable energy, coming from fossil-based fuels such as coal, natural gas, or crude oil, or from non-renewable generation technologies like nuclear power.a
In 2025, Biogen consumed a total of 1.61 million Gigajoules of energy, of which 31.53% was derived from renewable sources, including biofuels, biomass, biogas, solar, and wind power.a
This moderate level of renewable energy adoption indicates that Biogen is transitioning toward cleaner energy sources, though a significant share of its energy mix still relies on non-renewable inputs.
Since 2022, Biogen's total energy consumption decreased by 5.65%, and remained stable in 2025, suggesting earlier reductions may have leveled off.a
Over the same period, the share of renewable energy increased by 9.64%, while holding steady in 2025, indicating past gains that have recently stabilized.a
Overall, Biogen’s energy trends reveal a complex picture, with variations in total consumption and renewable sourcing. A closer examination of operational drivers and sourcing strategies is needed to fully assess the company’s environmental impact.
