Since 2023, Insmed's Scope 1 emissions have increased by 136.43%, reflecting a rising long-term trend in Scope 1 emissions over time.ac
Compared to the previous year (2024), Insmed's Scope 1 emissions increased by 57.38%, suggesting that the company faced challenges in reducing emissions from its directly owned or controlled operations.ab
In 2025, Insmed reported Scope 2 greenhouse gas (GHG) emissions of 2,069 tCO₂e using the market-based method and 2,264 tCO₂e using the location-based method.a
Compared to the previous year (2024), Insmed's Scope 2 emissions (Location-Based) rose by 11.25% in 2025, suggesting that the company faced challenges in reducing emissions from purchased electricity and energyab
In 2025, Insmed reported its Scope 2 emissions using the market-based method and using the location-based method.a
In 2025, Insmed reported 96,057 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 Insmed includes a breakdown across 8 of the 15 Scope 3 categories defined by the GHG Protocol, up from 7 in 2024, reflecting improved emissions accounting practices and greater transparency across the company's value chaina
In 2025, Insmed reported total Scope 3 emissions of 96,057 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 100% of these emissions originated from upstream activities such as purchased goods and capital goods, while 0% came from downstream activities like product use, distribution, and end-of-life treatment.a
Compared to the previous year (2024), Insmed's Scope 3 emissions increased by 43.84%, suggesting that the company faced challenges in reducing emissions across its value chain.ab
In 2025, Insmed reported emissions for 8 out of the 15 Scope 3 categories defined by the GHG Protocol.a
This partial disclosure allows for some insight into the company's indirect impacts.
In 2025, the largest contributors to Insmed's Scope 3 emissions were:a
In 2025, Insmed reported Scope 1 greenhouse gas (GHG) emissions of 2,622 tCO₂e and total revenues of USD 606 millions. This translates into an emissions intensity of 4.32 tCO₂e per millions USD.a
In 2025, Insmed reported a Scope 1 emissions intensity of 4.32 tCO₂e per millions USD. Compared to the peer group median of 2.76, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2025, Insmed ranked 14 out of 21 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Insmed is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, Insmed reported a total carbon footprint of 100,943 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 43.22% increase compared to 2024, suggesting a rise in emissions across its operations or value chain.ab
The largest contributor to Insmed's total carbon footprint was Scope 3 emissions, accounting for 95.16% of the company's total carbon footprint, followed by Scope 1 emissions at 2.6%.a
