In 2025, Fortum reported its Scope 2 emissions using the market-based method and using the location-based method.a
In 2025, Fortum reported 11,202,600 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 Fortum includes a breakdown across 15 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, Fortum reported total Scope 3 emissions of 11,202,600 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 87.47% of these emissions originated from upstream activities such as purchased goods and capital goods, while 12.53% came from downstream activities like product use, distribution, and end-of-life treatment.a
Since 2019, Fortum's Scope 3 emissions have increased by 92.84%, reflecting a rising long-term trend in Scope 3 emissions over time.ac
Compared to the previous year (2024), Fortum's Scope 3 emissions remained relatively stable, indicating that Fortum's emissions have plateaued with no significant change in its value chain footprint.ab
In 2025, Fortum reported emissions for 15 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 Fortum's Scope 3 emissions were:a
In 2025, Fortum reported Scope 1 greenhouse gas (GHG) emissions of 757,800 tCO₂e and total revenues of USD 5,865 millions. This translates into an emissions intensity of 129.2 tCO₂e per millions USD.a
In 2025, Fortum reported a Scope 1 emissions intensity of 129.2 tCO₂e per millions USD. Compared to the peer group median of 34.86, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2025, Fortum ranked 15 out of 25 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Fortum is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, Fortum reported a total carbon footprint of 12,139,800 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 5.84% decrease compared to 2024, indicating progress in reducing its overall greenhouse gas output.ab
The largest contributor to Fortum's total carbon footprint was Scope 3 emissions, accounting for 92.28% of the company's total carbon footprint, followed by Scope 1 emissions at 6.24%.a
