In 2025, Leonardo 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).
Leonardo has also provided a category-level breakdown for 9 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 Leonardo amounted to 373,101 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 Leonardo decreased by 7.15%, 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 Leonardo were 185,262 metric tons of CO₂ equivalent (tCO₂e).a
Since 2020, Leonardo's Scope 1 emissions have decreased by 48.5%, reflecting a declining long-term trend in Scope 1 emissions over time.ad
Compared to the previous year (2024), Leonardo's Scope 1 emissions remained relatively stable, indicating that Leonardo's emissions have plateaued with no significant change in its operational footprint.a
In 2025, Leonardo reported Scope 2 greenhouse gas (GHG) emissions of 53,090 tCO₂e using the market-based method and 187,839 tCO₂e using the location-based method.a
Since 2020, Leonardo's Scope 2 greenhouse gas (GHG) emissions (Location-Based) have decreased by 24.55%, reflecting a declining long-term trend in Scope 2 emissions over time.ad
Compared to the previous year (2024), Leonardo's Scope 2 emissions (Location-Based) fell by 13.19% in 2025, showing that the company has made progress in taking action to reduce the climate impact of its energy consumption.a
In 2025, Leonardo reported its Scope 2 emissions using the market-based method and using the location-based method.a
In 2025, Leonardo reported 5,627,192 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 Leonardo includes a breakdown across 9 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, Leonardo reported total Scope 3 emissions of 5,627,192 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 56.47% of these emissions originated from upstream activities such as purchased goods and capital goods, while 43.53% came from downstream activities like product use, distribution, and end-of-life treatment.a
Since 2020, Leonardo's Scope 3 emissions have increased by 2,612.88%, reflecting a rising long-term trend in Scope 3 emissions over time.ad
Compared to the previous year (2024), Leonardo's Scope 3 emissions remained relatively stable, indicating that Leonardo's emissions have plateaued with no significant change in its value chain footprint.a
In 2025, Leonardo reported emissions for 9 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 Leonardo's Scope 3 emissions were:a
In 2025, Leonardo reported Scope 1 greenhouse gas (GHG) emissions of 185,262 tCO₂e and total revenues of USD 22,929 millions. This translates into an emissions intensity of 8.08 tCO₂e per millions USD.a
In 2025, Leonardo reported a Scope 1 emissions intensity of 8.08 tCO₂e per millions USD. Compared to the peer group median of 5.39, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2025, Leonardo ranked 18 out of 24 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Leonardo is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, Leonardo reported a total carbon footprint of 6,000,293 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 7.74% increase compared to 2024, suggesting a rise in emissions across its operations or value chain.a
The largest contributor to Leonardo's total carbon footprint was Scope 3 emissions, accounting for 93.78% of the company's total carbon footprint, followed by Scope 2 emissions at 3.13%.a
