In 2025, Abb 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).
Abb has also provided a category-level breakdown for 12 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 Abb amounted to 374,000 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 Abb decreased by 7.65%, 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 Abb were 119,000 metric tons of CO₂ equivalent (tCO₂e).a
Since 2019, Abb's Scope 1 emissions have decreased by 69.95%, reflecting a declining long-term trend in Scope 1 emissions over time.ac
Compared to the previous year (2024), Abb's Scope 1 emissions remained relatively stable, indicating that Abb's emissions have plateaued with no significant change in its operational footprint.a
In 2025, Abb reported Scope 2 greenhouse gas (GHG) emissions of 15,000 tCO₂e using the market-based method and 255,000 tCO₂e using the location-based method.a
Compared to the previous year (2024), Abb's Scope 2 emissions (Location-Based) fell by 10.84% in 2025, showing that the company has made progress in taking action to reduce the climate impact of its energy consumption.a
In 2025, Abb reported its Scope 2 emissions using the market-based method and using the location-based method.a
In 2025, Abb reported 425,310,000 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 Abb includes a breakdown across 12 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, Abb reported total Scope 3 emissions of 425,310,000 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 2.55% of these emissions originated from upstream activities such as purchased goods and capital goods, while 97.45% came from downstream activities like product use, distribution, and end-of-life treatment.a
Since 2019, Abb's Scope 3 emissions have increased by 237.46%, reflecting a rising long-term trend in Scope 3 emissions over time.ac
Compared to the previous year (2024), Abb's Scope 3 emissions remained relatively stable, indicating that Abb's emissions have plateaued with no significant change in its value chain footprint.a
In 2025, Abb reported emissions for 12 out of the 15 Scope 3 categories defined by the GHG Protocol.a
This reflects a high level of granularity and transparency in the company's emissions reporting.
In 2025, the largest contributors to Abb's Scope 3 emissions were:a
In 2025, Abb reported Scope 1 greenhouse gas (GHG) emissions of 119,000 tCO₂e and total revenues of USD 33,220 millions. This translates into an emissions intensity of 3.58 tCO₂e per millions USD.a
In 2025, Abb reported a Scope 1 emissions intensity of 3.58 tCO₂e per millions USD. Compared to the peer group median of 6.74, this places the company below its industry benchmark, indicating it is more carbon-efficient than most competitors.a
In 2025, Abb ranked 10 out of 25 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Abb is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, Abb reported a total carbon footprint of 425,684,000 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 8.4% increase compared to 2024, suggesting a rise in emissions across its operations or value chain.a
The largest contributor to Abb's total carbon footprint was Scope 3 emissions, accounting for 99.91% of the company's total carbon footprint, followed by Scope 2 emissions at 0.06%.a
