In 2025, the total operational greenhouse gas (GHG) emissions of ALS amounted to 90,482 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 ALS increased by 5.91%, suggesting that the company faced challenges in reducing its emissions from its core operations.a
In 2025, the total Scope 1 emissions of ALS were 36,970 metric tons of CO₂ equivalent (tCO₂e).a
Since 2020, ALS's Scope 1 emissions have increased by 14.87%, reflecting a rising long-term trend in Scope 1 emissions over time.ab
Compared to the previous year (2024), ALS's Scope 1 emissions increased by 9.25%, suggesting that the company faced challenges in reducing emissions from its directly owned or controlled operations.a
In 2025, ALS reported Scope 2 greenhouse gas (GHG) emissions of 1,603 tCO₂e using the market-based method and 53,512 tCO₂e using the location-based method.a
Since 2020, ALS's Scope 2 greenhouse gas (GHG) emissions (Location-Based) have remained relatively stable, indicating that ALS's emissions have plateaued with no significant change in its energy consumption footprint.ab
Compared to the previous year (2024), ALS's Scope 2 emissions (Location-Based) have remained relatively stable, indicating that ALS's emissions have plateaued with no significant change in its energy consumption footprint.a
In 2025, ALS reported its Scope 2 emissions using the market-based method and using the location-based method.a
In 2025, ALS reported 289,326 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 ALS includes a breakdown across 7 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, ALS reported total Scope 3 emissions of 289,326 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
Since 2020, ALS's Scope 3 emissions have increased by 22,121.66%, reflecting a rising long-term trend in Scope 3 emissions over time.ac
Compared to the previous year (2024), ALS's Scope 3 emissions remained relatively stable, indicating that ALS's emissions have plateaued with no significant change in its value chain footprint.a
In 2025, ALS reported emissions for 7 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 ALS's Scope 3 emissions were:a
In 2025, ALS reported Scope 1 greenhouse gas (GHG) emissions of 36,970 tCO₂e and total revenues of USD 1,875 millions. This translates into an emissions intensity of 19.72 tCO₂e per millions USD.a
In 2025, ALS reported a Scope 1 emissions intensity of 19.72 tCO₂e per millions USD. Compared to the peer group median of 0.64, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2025, ALS ranked 22 out of 23 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
This places ALS among the least efficient performers, with one of the highest emissions intensities in its sector.a
In 2025, ALS reported a total carbon footprint of 379,808 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 3.82% increase compared to 2024, suggesting a rise in emissions across its operations or value chain.a
The largest contributor to ALS's total carbon footprint was Scope 3 emissions, accounting for 76.18% of the company's total carbon footprint, followed by Scope 2 emissions at 14.09%.a
