Our number one goal

To become climate neutral in Switzerland

We aim to be climate neutral across the entire value chain by 2025. We’ll achieve this through avoidance, reduction and offsetting residual emissions. And by 2035, we are committed to becoming net zero for the entire Swisscom Group according to SBTi. *

*The target boundary includes land related emissions and removals from bioenergy feedstocks.   

Direct emissions: -90%

Graphic CO2 emissions

We have already reduced over 80% of our direct emissions since 1990. By 2025, we will have reduced them by a further 10%. We offset the unavoidable residual emissions. We want to further reduce our carbon footprint.

Scope 2 emissions in 1990 and 2000 are based on calculations.

Renewable energies

Since 2010, all of the energy we use has come from renewable sources. Certifications of origin attest to the CO2-free production of the purchased energy. We also operate 114 photovoltaic plants, with which we produce our own electricity.


Efficient infrastructure

To reduce emissions from the consumption of thermal energy, we are systematically replacing all of our heating systems that need updating with heat pumps, wood heaters and heat recovery from our own operations.

Electric vehicle charging

Sustainable mobility

Swisscom has one of the largest company fleets in Switzerland - mobility is a key driver of our direct CO2 emissions. In order to travel sustainably, we have set ourselves the goal of halving direct CO2 emissions from mobility by 2025 and eliminating them completely by 2030.

Indirect emissions: -50%

Graph indirect emissions

At 306 kt CO2, indirect emissions account for by far the largest share of our carbon footprint. By 2025, we aim to reduce this by 50% and offset the rest.

Start of indirect emissions measurement in 2013.

Our second goal

To save 1 million tonnes of CO2

We want to make an additional contribution to climate protection by 2025 by helping our customers save annually one million tons of CO2 with sustainable products and services.

Saving CO2 with ICT services

Today, we are already enabling our customers to reduce their carbon footprint by more than 1.1 m tonnes of CO2 eq through innovative ICT solutions. We want to ramp up this positive contribution to climate protection by 2025, helping to save the equivalent of 2% of all CO2 emissions in Switzerland.

Work Smart services

We are helping to avoid unnecessary travel through video communication and online collaboration. The COVID pandemic in particular revealed the emissions-reducing potential of these solutions.


IoT technologies

By facilitating the IoT-based remote monitoring and control of equipment such as heaters, tanks and containers, we are helping to reduce unnecessary journeys and, in turn, CO2 emissions.

Data center

Cloud services

By moving processing power and data storage to our highly efficient data centres, we are contributing to climate protection through energy savings while also reducing costs and improving security.

Swisscom Shop


From till receipts and paper billing to brochures and manuals, paperless digital solutions allow us to reduce emissions while improving usability and service quality.

Old smartphones

Circular economy

By supporting the circular economy, we are helping to give used smartphones and laptops a new lease of life. Extending service life helps to conserve resources and save energy.

How we offset emissions

Swisscom’s operations have been climate neutral since 2020. Since 2022, subscriptions, network and devices have also been climate neutral. Our customers enjoy climate-neutral surfing, streaming and calls without additional costs or waivers. We offset unavoidable CO2 emissions through high-quality climate protection projects selected according to strict criteria.
