In 2025, the largest contributors to Alten's Scope 3 emissions were:a
In 2025, Alten reported Scope 1 greenhouse gas (GHG) emissions of 7,741 tCO₂e and total revenues of USD 4,819 millions. This translates into an emissions intensity of 1.61 tCO₂e per millions USD.a
In 2025, Alten reported a Scope 1 emissions intensity of 1.61 tCO₂e per millions USD. Compared to the peer group median of 0.4, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2025, Alten ranked 23 out of 24 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
This places Alten among the least efficient performers, with one of the highest emissions intensities in its sector.a
In 2025, Alten reported a total carbon footprint of 156,998 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 2.65% decrease compared to 2024, indicating progress in reducing its overall greenhouse gas output.a
The largest contributor to Alten's total carbon footprint was Scope 3 emissions, accounting for 89.33% of the company's total carbon footprint, followed by Scope 2 emissions at 5.74%.a
