In 2025, Biogen completed a corporate carbon footprint assessment and publicly disclosed its greenhouse gas (GHG) emissions according to the GHG Protocol, covering Scope 1 (direct emissions from owned or controlled sources), Scope 2 (indirect emissions from purchased energy) and Scope 3 (indirect emissions across the value chain).
Biogen has also provided a category-level breakdown for 10 out of 15 Scope 3 emissions categories, offering greater transparency into its value chain emissions.

In 2025, the total operational greenhouse gas (GHG) emissions of Biogen amounted to 89,766 metric tons of CO2 equivalent. This figure includes both direct emissions from owned or controlled sources (Scope 1) and indirect emissions from purchased energy (Scope 2).a
Compared to 2024, the total operational greenhouse gas (GHG) emissions of Biogen increased by 0.33%, suggesting that the company faced challenges in reducing its emissions from its core operations.a
In 2025, the total Scope 1 emissions of Biogen were 56,948 metric tons of CO₂ equivalent (tCO₂e).a
Since 2019, Biogen's Scope 1 emissions have decreased by 15.04%, reflecting a declining long-term trend in Scope 1 emissions over time.ab
Compared to the previous year (2024), Biogen's Scope 1 emissions remained relatively stable, indicating that Biogen's emissions have plateaued with no significant change in its operational footprint.a
In 2025, Biogen reported Scope 2 greenhouse gas (GHG) emissions of 1,507 tCO₂e using the market-based method and 32,818 tCO₂e using the location-based method.a
Since 2019, Biogen's Scope 2 greenhouse gas (GHG) emissions (Location-Based) have decreased by 12.98%, reflecting a declining long-term trend in Scope 2 emissions over time.ab
Compared to the previous year (2024), Biogen's Scope 2 emissions (Location-Based) have remained relatively stable, indicating that Biogen's emissions have plateaued with no significant change in its energy consumption footprint.a
In 2025, Biogen reported its Scope 2 emissions using the market-based method and using the location-based method.a
In 2025, Biogen reported 297,768 metric tons of CO₂ equivalent (tCO₂e) of Scope 3 greenhouse gas (GHG) emissions, representing indirect emissions across its upstream and downstream value chain.a
The 2025 disclosure of Biogen includes a breakdown across 10 of the 15 Scope 3 categories defined by the GHG Protocol, matching the level of disclosure in 2024, demonstrating consistent Scope 3 emissions reporting coverage year over year.a
In 2025, Biogen reported total Scope 3 emissions of 297,768 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 98.65% of these emissions originated from upstream activities such as purchased goods and capital goods, while 1.35% came from downstream activities like product use, distribution, and end-of-life treatment.a
Since 2019, Biogen's Scope 3 emissions have decreased by 29.87%, reflecting a declining long-term trend in Scope 3 emissions over time.ab
Compared to the previous year (2024), Biogen's Scope 3 emissions increased by 11.5%, suggesting that the company faced challenges in reducing emissions across its value chain.a
In 2025, Biogen reported emissions for 10 out of the 15 Scope 3 categories defined by the GHG Protocol.a
This reflects a high level of granularity and transparency in the company's emissions reporting.
In 2025, the largest contributors to Biogen's Scope 3 emissions were:a
In 2025, Biogen reported Scope 1 greenhouse gas (GHG) emissions of 56,948 tCO₂e and total revenues of USD 9,891 millions. This translates into an emissions intensity of 5.76 tCO₂e per millions USD.a
In 2025, Biogen reported a Scope 1 emissions intensity of 5.76 tCO₂e per millions USD. Compared to the peer group median of 4.98, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2025, Biogen ranked 16 out of 25 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Biogen is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, Biogen reported a total carbon footprint of 387,534 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 8.7% increase compared to 2024, suggesting a rise in emissions across its operations or value chain.a
The largest contributor to Biogen's total carbon footprint was Scope 3 emissions, accounting for 76.84% of the company's total carbon footprint, followed by Scope 1 emissions at 14.69%.a
