In 2025, the largest contributors to DIA's Scope 3 emissions were:a
In 2025, DIA reported Scope 1 greenhouse gas (GHG) emissions of 195,469.95 tCO₂e and total revenues of USD 6,719 millions. This translates into an emissions intensity of 29.09 tCO₂e per millions USD.a
In 2025, DIA reported a Scope 1 emissions intensity of 29.09 tCO₂e per millions USD. Compared to the peer group median of 8.2, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2025, DIA 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 DIA among the least efficient performers, with one of the highest emissions intensities in its sector.a
In 2025, DIA reported a total carbon footprint of 4,535,103.5 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 3.25% decrease compared to 2024, indicating progress in reducing its overall greenhouse gas output.ab
The largest contributor to DIA's total carbon footprint was Scope 3 emissions, accounting for 91.64% of the company's total carbon footprint, followed by Scope 1 emissions at 4.31%.a
