In 2025, Ecolab 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).
Ecolab has also provided a category-level breakdown for 11 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 Ecolab amounted to 400,909 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 Ecolab decreased by 6.47%, showing that the company has made progress in taking action to reduce the climate impact of its operations.ab
In 2025, the total Scope 1 emissions of Ecolab were 255,784 metric tons of CO₂ equivalent (tCO₂e).a
Since 2019, Ecolab's Scope 1 emissions have decreased by 19.86%, reflecting a declining long-term trend in Scope 1 emissions over time.ac
Compared to the previous year (2024), Ecolab's Scope 1 emissions decreased by 5.3%, highlighting the company's efforts to lower direct emissions from assets it owns or controls.ab
In 2025, Ecolab reported Scope 2 greenhouse gas (GHG) emissions of 29,159 tCO₂e using the market-based method and 145,125 tCO₂e using the location-based method.a
Since 2019, Ecolab's Scope 2 greenhouse gas (GHG) emissions (Location-Based) have remained relatively stable, indicating that Ecolab's emissions have plateaued with no significant change in its energy consumption footprint.ac
Compared to the previous year (2024), Ecolab's Scope 2 emissions (Location-Based) have remained relatively stable, indicating that Ecolab's emissions have plateaued with no significant change in its energy consumption footprint.ab
In 2025, Ecolab reported its Scope 2 emissions using the market-based method and using the location-based method.a
In 2025, Ecolab reported 54,484 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 Ecolab includes a breakdown across 1 of the 15 Scope 3 categories defined by the GHG Protocol, down from 10 in 2024, indicating a decline in reporting granularity and reduced insight into the company's full value chain emissions.a
In 2025, Ecolab reported total Scope 3 emissions of 54,484 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 2019, Ecolab's Scope 3 emissions have decreased by 99.35%, reflecting a declining long-term trend in Scope 3 emissions over time.ac
Compared to the previous year (2024), Ecolab's Scope 3 emissions decreased by 99.62%, highlighting the company's efforts to lower indirect emissions from its value chain.ab
In 2025, Ecolab reported emissions for 1 out of the 15 Scope 3 categories defined by the GHG Protocol.a
The limited disclosure restricts visibility into specific emission sources across the company's value chain.
In 2025, the largest contributors to Ecolab's Scope 3 emissions were:a
In 2025, Ecolab reported Scope 1 greenhouse gas (GHG) emissions of 255,784 tCO₂e and total revenues of USD 16,081 millions. This translates into an emissions intensity of 15.91 tCO₂e per millions USD.a
In 2025, Ecolab reported a Scope 1 emissions intensity of 15.91 tCO₂e per millions USD. Compared to the peer group median of 64.44, this places the company below its industry benchmark, indicating it is more carbon-efficient than most competitors.a
In 2025, Ecolab ranked 6 out of 25 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Ecolab is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, Ecolab reported a total carbon footprint of 455,393 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 96.92% decrease compared to 2024, indicating progress in reducing its overall greenhouse gas output.ab
The largest contributor to Ecolab's total carbon footprint was Scope 1 emissions, accounting for 56.17% of the company's total carbon footprint, followed by Scope 2 emissions at 31.87%.a
