In 2025, the total operational greenhouse gas (GHG) emissions of Biomerieux amounted to 61,000 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 Biomerieux decreased by 1.61%, 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 Biomerieux were 24,000 metric tons of CO₂ equivalent (tCO₂e).a
Since 2019, Biomerieux's Scope 1 emissions have decreased by 7.69%, reflecting a declining long-term trend in Scope 1 emissions over time.a
Compared to the previous year (2024), Biomerieux's Scope 1 emissions increased by 9.09%, suggesting that the company faced challenges in reducing emissions from its directly owned or controlled operations.a
In 2025, Biomerieux reported Scope 2 greenhouse gas (GHG) emissions of 22,000 tCO₂e using the market-based method and 37,000 tCO₂e using the location-based method.a
Since 2019, Biomerieux's Scope 2 greenhouse gas (GHG) emissions (Location-Based) have increased by 12.12%, reflecting a rising long-term trend in Scope 2 emissions over time.a
Compared to the previous year (2024), Biomerieux's Scope 2 emissions (Location-Based) have remained relatively stable, indicating that Biomerieux's emissions have plateaued with no significant change in its energy consumption footprint.a
In 2025, Biomerieux reported its Scope 2 emissions using the market-based method and using the location-based method.a
In 2025, Biomerieux reported 1,103,000 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 Biomerieux 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, Biomerieux reported total Scope 3 emissions of 1,103,000 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 86.13% of these emissions originated from upstream activities such as purchased goods and capital goods, while 13.87% came from downstream activities like product use, distribution, and end-of-life treatment.a
Since 2019, Biomerieux's Scope 3 emissions have increased by 23.79%, reflecting a rising long-term trend in Scope 3 emissions over time.a
Compared to the previous year (2024), Biomerieux's Scope 3 emissions remained relatively stable, indicating that Biomerieux's emissions have plateaued with no significant change in its value chain footprint.a
In 2025, Biomerieux 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 Biomerieux's Scope 3 emissions were:a
In 2025, Biomerieux reported Scope 1 greenhouse gas (GHG) emissions of 24,000 tCO₂e and total revenues of USD 4,785 millions. This translates into an emissions intensity of 5.02 tCO₂e per millions USD.a
In 2025, Biomerieux reported a Scope 1 emissions intensity of 5.02 tCO₂e per millions USD. Compared to the peer group median of 4.56, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2025, Biomerieux ranked 15 out of 23 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Biomerieux is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, Biomerieux reported a total carbon footprint of 1,164,000 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 4.12% decrease compared to 2024, indicating progress in reducing its overall greenhouse gas output.a
The largest contributor to Biomerieux's total carbon footprint was Scope 3 emissions, accounting for 94.76% of the company's total carbon footprint, followed by Scope 2 emissions at 3.18%.a
