In 2025, ArcelorMittal reported its Scope 2 emissions using the market-based method and using the location-based method.a
In 2025, ArcelorMittal reported 98,700,000 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 ArcelorMittal includes a breakdown across 5 of the 15 Scope 3 categories defined by the GHG Protocol, up from 0 in 2024, reflecting improved emissions accounting practices and greater transparency across the company's value chaina
In 2025, ArcelorMittal reported total Scope 3 emissions of 98,700,000 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 31.25% of these emissions originated from upstream activities such as purchased goods and capital goods, while 68.75% came from downstream activities like product use, distribution, and end-of-life treatment.a
Since 2020, ArcelorMittal's Scope 3 emissions have increased by 1,008.99%, reflecting a rising long-term trend in Scope 3 emissions over time.ab
Compared to the previous year (2024), ArcelorMittal's Scope 3 emissions increased by 1,075%, suggesting that the company faced challenges in reducing emissions across its value chain.a
In 2025, ArcelorMittal reported emissions for 5 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 ArcelorMittal's Scope 3 emissions were:a
In 2025, ArcelorMittal reported Scope 1 greenhouse gas (GHG) emissions of 93,700,000 tCO₂e and total revenues of USD 61,352 millions. This translates into an emissions intensity of 1,527.25 tCO₂e per millions USD.a
In 2025, ArcelorMittal reported a Scope 1 emissions intensity of 1,527.25 tCO₂e per millions USD. Compared to the peer group median of 940.54, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2025, ArcelorMittal ranked 17 out of 25 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
ArcelorMittal is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, ArcelorMittal reported a total carbon footprint of 198,150,000 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 78.67% increase compared to 2024, suggesting a rise in emissions across its operations or value chain.a
The largest contributor to ArcelorMittal's total carbon footprint was Scope 3 emissions, accounting for 49.81% of the company's total carbon footprint, followed by Scope 1 emissions at 47.29%.a
