In 2025, ACS 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).
ACS 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 ACS amounted to 2,354,974 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 ACS increased by 32.4%, suggesting that the company faced challenges in reducing its emissions from its core operations.a
In 2025, the total Scope 1 emissions of ACS were 2,249,245 metric tons of CO₂ equivalent (tCO₂e).a
Since 2019, ACS's Scope 1 emissions have decreased by 25.06%, reflecting a declining long-term trend in Scope 1 emissions over time.ad
Compared to the previous year (2024), ACS's Scope 1 emissions increased by 35.1%, suggesting that the company faced challenges in reducing emissions from its directly owned or controlled operations.a
In 2025, ACS reported Scope 2 greenhouse gas (GHG) emissions of 105,167 tCO₂e using the market-based method and 105,729 tCO₂e using the location-based method.a
Compared to the previous year (2024), ACS's Scope 2 emissions (Location-Based) have remained relatively stable, indicating that ACS's emissions have plateaued with no significant change in its energy consumption footprint.a
In 2025, ACS reported its Scope 2 emissions using the market-based method and using the location-based method.a
In 2025, ACS reported 6,137,180 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 ACS includes a breakdown across 10 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, ACS reported total Scope 3 emissions of 6,137,180 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 95.49% of these emissions originated from upstream activities such as purchased goods and capital goods, while 4.51% came from downstream activities like product use, distribution, and end-of-life treatment.a
Since 2019, ACS's Scope 3 emissions have increased by 141.79%, reflecting a rising long-term trend in Scope 3 emissions over time.ae
Compared to the previous year (2024), ACS's Scope 3 emissions remained relatively stable, indicating that ACS's emissions have plateaued with no significant change in its value chain footprint.a
In 2025, ACS reported emissions for 10 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 ACS's Scope 3 emissions were:a
In 2025, ACS reported Scope 1 greenhouse gas (GHG) emissions of 2,249,245 tCO₂e and total revenues of USD 58,604 millions. This translates into an emissions intensity of 38.38 tCO₂e per millions USD.a
In 2025, ACS reported a Scope 1 emissions intensity of 38.38 tCO₂e per millions USD. Compared to the peer group median of 16.94, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2025, ACS ranked 22 out of 24 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
This places ACS among the least efficient performers, with one of the highest emissions intensities in its sector.a
In 2025, ACS reported a total carbon footprint of 8,492,154 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 12.08% increase compared to 2024, suggesting a rise in emissions across its operations or value chain.a
The largest contributor to ACS's total carbon footprint was Scope 3 emissions, accounting for 72.27% of the company's total carbon footprint, followed by Scope 1 emissions at 26.49%.a
