In 2025, the total operational greenhouse gas (GHG) emissions of Thermo Fisher Scientific amounted to 754,174 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 Thermo Fisher Scientific decreased by 0.65%, showing that the company has made progress in taking action to reduce the climate impact of its operations.a
In 2025, the total Scope 1 emissions of Thermo Fisher Scientific were 324,463 metric tons of CO₂ equivalent (tCO₂e).a
Since 2019, Thermo Fisher Scientific's Scope 1 emissions have increased by 6.71%, reflecting a rising long-term trend in Scope 1 emissions over time.ab
Compared to the previous year (2024), Thermo Fisher Scientific's Scope 1 emissions increased by 1.66%, suggesting that the company faced challenges in reducing emissions from its directly owned or controlled operations.a
In 2025, Thermo Fisher Scientific reported Scope 2 greenhouse gas (GHG) emissions of 150,583 tCO₂e using the market-based method and 429,711 tCO₂e using the location-based method.a
Since 2019, Thermo Fisher Scientific's Scope 2 greenhouse gas (GHG) emissions (Location-Based) have remained relatively stable, indicating that Thermo Fisher Scientific's emissions have plateaued with no significant change in its energy consumption footprint.ab
Compared to the previous year (2024), Thermo Fisher Scientific's Scope 2 emissions (Location-Based) have remained relatively stable, indicating that Thermo Fisher Scientific's emissions have plateaued with no significant change in its energy consumption footprint.a
In 2025, Thermo Fisher Scientific reported its Scope 2 emissions using the market-based method and using the location-based method.a
In 2025, Thermo Fisher Scientific reported 7,148,147 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 Thermo Fisher Scientific includes a breakdown across 9 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, Thermo Fisher Scientific reported total Scope 3 emissions of 7,148,147 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 82.15% of these emissions originated from upstream activities such as purchased goods and capital goods, while 17.85% came from downstream activities like product use, distribution, and end-of-life treatment.a
Compared to the previous year (2024), Thermo Fisher Scientific's Scope 3 emissions remained relatively stable, indicating that Thermo Fisher Scientific's emissions have plateaued with no significant change in its value chain footprint.a
In 2025, Thermo Fisher Scientific reported emissions for 9 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 Thermo Fisher Scientific's Scope 3 emissions were:a
In 2025, Thermo Fisher Scientific reported Scope 1 greenhouse gas (GHG) emissions of 324,463 tCO₂e and total revenues of USD 44,557 millions. This translates into an emissions intensity of 7.28 tCO₂e per millions USD.a
In 2025, Thermo Fisher Scientific reported a Scope 1 emissions intensity of 7.28 tCO₂e per millions USD. Compared to the peer group median of 4.38, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2025, Thermo Fisher Scientific ranked 18 out of 24 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Thermo Fisher Scientific is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, Thermo Fisher Scientific reported a total carbon footprint of 7,902,321 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 3.18% decrease compared to 2024, indicating progress in reducing its overall greenhouse gas output.a
The largest contributor to Thermo Fisher Scientific's total carbon footprint was Scope 3 emissions, accounting for 90.46% of the company's total carbon footprint, followed by Scope 2 emissions at 5.44%.a
