In 2025, ACC 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).
ACC 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 ACC amounted to 14,162,230 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 ACC decreased by 8.05%, 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 ACC were 13,488,976 metric tons of CO₂ equivalent (tCO₂e).a
Since 2019, ACC's Scope 1 emissions have decreased by 19.6%, reflecting a declining long-term trend in Scope 1 emissions over time.ab
Compared to the previous year (2024), ACC's Scope 1 emissions decreased by 8.86%, highlighting the company's efforts to lower direct emissions from assets it owns or controls.a
In 2025, ACC reported Scope 2 greenhouse gas (GHG) emissions of 625,212 tCO₂e using the market-based method and 673,254 tCO₂e using the location-based method.a
Compared to the previous year (2024), ACC's Scope 2 emissions (Location-Based) rose by 11.88% in 2025, suggesting that the company faced challenges in reducing emissions from purchased electricity and energya
In 2025, ACC reported its Scope 2 emissions using the market-based method and using the location-based method.a
In 2025, ACC reported 4,789,976 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 ACC includes a breakdown across 11 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, ACC reported total Scope 3 emissions of 4,789,976 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 97.45% of these emissions originated from upstream activities such as purchased goods and capital goods, while 2.55% came from downstream activities like product use, distribution, and end-of-life treatment.a
Since 2019, ACC's Scope 3 emissions have increased by 636.82%, reflecting a rising long-term trend in Scope 3 emissions over time.ab
Compared to the previous year (2024), ACC's Scope 3 emissions remained relatively stable, indicating that ACC's emissions have plateaued with no significant change in its value chain footprint.a
In 2025, ACC reported emissions for 11 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 ACC's Scope 3 emissions were:a
In 2025, ACC reported Scope 1 greenhouse gas (GHG) emissions of 13,488,976 tCO₂e and total revenues of USD 2,452 millions. This translates into an emissions intensity of 5,502.11 tCO₂e per millions USD.a
In 2025, ACC reported a Scope 1 emissions intensity of 5,502.11 tCO₂e per millions USD. Compared to the peer group median of 7,582.69, this places the company below its industry benchmark, indicating it is more carbon-efficient than most competitors.a
In 2025, ACC ranked 12 out of 24 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
ACC is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, ACC reported a total carbon footprint of 18,952,206 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 4.46% decrease compared to 2024, indicating progress in reducing its overall greenhouse gas output.a
The largest contributor to ACC's total carbon footprint was Scope 1 emissions, accounting for 71.17% of the company's total carbon footprint, followed by Scope 3 emissions at 25.27%.a
