In 2025, Proximus reported 355,380 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 Proximus includes a breakdown across 6 of the 15 Scope 3 categories defined by the GHG Protocol, down from 7 in 2024, indicating a decline in reporting granularity and reduced insight into the company's full value chain emissions.a
In 2025, Proximus reported total Scope 3 emissions of 355,380 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 36.54% of these emissions originated from upstream activities such as purchased goods and capital goods, while 63.46% came from downstream activities like product use, distribution, and end-of-life treatment.a
Since 2019, Proximus's Scope 3 emissions have decreased by 52.13%, reflecting a declining long-term trend in Scope 3 emissions over time.ab
Compared to the previous year (2024), Proximus's Scope 3 emissions decreased by 10.98%, highlighting the company's efforts to lower indirect emissions from its value chain.a
In 2025, Proximus reported emissions for 6 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 Proximus's Scope 3 emissions were:a
In 2025, Proximus reported Scope 1 greenhouse gas (GHG) emissions of 19,757 tCO₂e and total revenues of USD 7,345 millions. This translates into an emissions intensity of 2.69 tCO₂e per millions USD.a
In 2025, Proximus reported a Scope 1 emissions intensity of 2.69 tCO₂e per millions USD. Compared to the peer group median of 2.79, this places the company below its industry benchmark, indicating it is more carbon-efficient than most competitors.a
In 2025, Proximus ranked 13 out of 24 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Proximus is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, Proximus reported a total carbon footprint of 405,046 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 11.84% decrease compared to 2024, indicating progress in reducing its overall greenhouse gas output.a
The largest contributor to Proximus's total carbon footprint was Scope 3 emissions, accounting for 87.74% of the company's total carbon footprint, followed by Scope 2 emissions at 7.38%.a
