In 2025, Outokumpu reported 2,237,699 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 Outokumpu includes a breakdown across 8 of the 15 Scope 3 categories defined by the GHG Protocol, up from 6 in 2024, reflecting improved emissions accounting practices and greater transparency across the company's value chaina
In 2025, Outokumpu reported total Scope 3 emissions of 2,237,699 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 94.06% of these emissions originated from upstream activities such as purchased goods and capital goods, while 5.94% came from downstream activities like product use, distribution, and end-of-life treatment.a
Since 2021, Outokumpu's Scope 3 emissions have decreased by 29.13%, reflecting a declining long-term trend in Scope 3 emissions over time.ab
Compared to the previous year (2024), Outokumpu's Scope 3 emissions remained relatively stable, indicating that Outokumpu's emissions have plateaued with no significant change in its value chain footprint.a
In 2025, Outokumpu reported emissions for 8 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 Outokumpu's Scope 3 emissions were:a
In 2025, Outokumpu reported Scope 1 greenhouse gas (GHG) emissions of 1,027,622 tCO₂e and total revenues of USD 6,429 millions. This translates into an emissions intensity of 159.85 tCO₂e per millions USD.a
In 2025, Outokumpu reported a Scope 1 emissions intensity of 159.85 tCO₂e per millions USD. Compared to the peer group median of 653.13, this places the company below its industry benchmark, indicating it is more carbon-efficient than most competitors.a
In 2025, Outokumpu ranked 11 out of 25 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Outokumpu is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, Outokumpu reported a total carbon footprint of 3,701,094 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 2.25% decrease compared to 2024, indicating progress in reducing its overall greenhouse gas output.a
The largest contributor to Outokumpu's total carbon footprint was Scope 3 emissions, accounting for 60.46% of the company's total carbon footprint, followed by Scope 1 emissions at 27.77%.a
