In 2025, Swisscom 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).
However, Swisscom has not published a category-level breakdown of its Scope 3 emissions, limiting visibility into specific value chain sources.

In 2025, the total operational greenhouse gas (GHG) emissions of Swisscom amounted to 144,158 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 Swisscom increased by 167.34%, suggesting that the company faced challenges in reducing its emissions from its core operations.ab
In 2025, the total Scope 1 emissions of Swisscom were 16,688 metric tons of CO₂ equivalent (tCO₂e).a
Since 2019, Swisscom's Scope 1 emissions have increased by 1.46%, reflecting a rising long-term trend in Scope 1 emissions over time.ac
Compared to the previous year (2024), Swisscom's Scope 1 emissions increased by 52.72%, suggesting that the company faced challenges in reducing emissions from its directly owned or controlled operations.ab
In 2025, Swisscom reported Scope 2 greenhouse gas (GHG) emissions of 1 tCO₂e using the market-based method and 127,470 tCO₂e using the location-based method.a
Since 2019, Swisscom's Scope 2 greenhouse gas (GHG) emissions (Location-Based) have increased by 162.01%, reflecting a rising long-term trend in Scope 2 emissions over time.ac
Compared to the previous year (2024), Swisscom's Scope 2 emissions (Location-Based) rose by 196.46% in 2025, suggesting that the company faced challenges in reducing emissions from purchased electricity and energyab
In 2025, Swisscom reported its Scope 2 emissions using the market-based method and using the location-based method.a
In 2025, Swisscom reported 799,740 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 Swisscom includes a breakdown across 0 of the 15 Scope 3 categories defined by the GHG Protocol, down from 11 in 2024, indicating a decline in reporting granularity and reduced insight into the company's full value chain emissions.a
In 2025, Swisscom reported total Scope 3 emissions of 799,740 metric tons of CO₂ equivalent (tCO₂e).a
Since 2019, Swisscom's Scope 3 emissions have increased by 135.67%, reflecting a rising long-term trend in Scope 3 emissions over time.ac
Compared to the previous year (2024), Swisscom's Scope 3 emissions increased by 149.24%, suggesting that the company faced challenges in reducing emissions across its value chain.ab
In 2025, Swisscom reported Scope 1 greenhouse gas (GHG) emissions of 16,688 tCO₂e and total revenues of USD 18,994 millions. This translates into an emissions intensity of 0.88 tCO₂e per millions USD.a
In 2025, Swisscom reported a Scope 1 emissions intensity of 0.88 tCO₂e per millions USD. Compared to the peer group median of 3.54, this places the company below its industry benchmark, indicating it is more carbon-efficient than most competitors.a
In 2025, Swisscom ranked 6 out of 25 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Swisscom is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, Swisscom reported a total carbon footprint of 943,898 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 151.85% increase compared to 2024, suggesting a rise in emissions across its operations or value chain.ab
The largest contributor to Swisscom's total carbon footprint was Scope 3 emissions, accounting for 84.73% of the company's total carbon footprint, followed by Scope 2 emissions at 13.5%.a
