In 2025, the total operational greenhouse gas (GHG) emissions of Voltalia amounted to 48,815 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 Voltalia increased by 35.4%, suggesting that the company faced challenges in reducing its emissions from its core operations.a
In 2025, the total Scope 1 emissions of Voltalia were 42,810 metric tons of CO₂ equivalent (tCO₂e).a
Since 2022, Voltalia's Scope 1 emissions have increased by 38.9%, reflecting a rising long-term trend in Scope 1 emissions over time.a
Compared to the previous year (2024), Voltalia's Scope 1 emissions increased by 26.18%, suggesting that the company faced challenges in reducing emissions from its directly owned or controlled operations.a
In 2025, Voltalia reported Scope 2 greenhouse gas (GHG) emissions of 6,005 tCO₂e using the market-based method and 6,005 tCO₂e using the location-based method.a
Since 2022, Voltalia's Scope 2 greenhouse gas (GHG) emissions (Location-Based) have increased by 616.59%, reflecting a rising long-term trend in Scope 2 emissions over time.a
Compared to the previous year (2024), Voltalia's Scope 2 emissions (Location-Based) rose by 182.72% in 2025, suggesting that the company faced challenges in reducing emissions from purchased electricity and energya
In 2025, Voltalia reported its Scope 2 emissions using the market-based method and using the location-based method.a
In 2025, Voltalia reported 629,466 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 Voltalia includes a breakdown across 9 of the 15 Scope 3 categories defined by the GHG Protocol, down from 10 in 2024, indicating a decline in reporting granularity and reduced insight into the company's full value chain emissions.a
In 2025, Voltalia reported total Scope 3 emissions of 629,466 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 95.76% of these emissions originated from upstream activities such as purchased goods and capital goods, while 4.24% came from downstream activities like product use, distribution, and end-of-life treatment.a
Since 2022, Voltalia's Scope 3 emissionshave remained relatively stable, indicating that Voltalia's emissions have plateaued with no significant change in its value chain footprint.a
Compared to the previous year (2024), Voltalia's Scope 3 emissions increased by 31.25%, suggesting that the company faced challenges in reducing emissions across its value chain.a
In 2025, Voltalia 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 Voltalia's Scope 3 emissions were:a
In 2025, Voltalia reported Scope 1 greenhouse gas (GHG) emissions of 42,810 tCO₂e and total revenues of USD 691 millions. This translates into an emissions intensity of 61.94 tCO₂e per millions USD.a
In 2025, Voltalia reported a Scope 1 emissions intensity of 61.94 tCO₂e per millions USD. Compared to the peer group median of 7.92, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2025, Voltalia ranked 17 out of 24 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Voltalia is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, Voltalia reported a total carbon footprint of 678,281 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 31.54% increase compared to 2024, suggesting a rise in emissions across its operations or value chain.a
The largest contributor to Voltalia's total carbon footprint was Scope 3 emissions, accounting for 92.8% of the company's total carbon footprint, followed by Scope 1 emissions at 6.31%.a
