Swisscom’s CO2 emissions

Swisscom maintains a greenhouse gas inventory and publishes its emissions according to recognised standards (ISO 14064). In accordance with the Greenhouse Gas Protocol, the company classifies its CO2 emissions as Scope 1 (direct emissions resulting from burning fossil fuels for heating and mobility or from refrigerants), Scope 2 (indirect emissions caused by purchased energies) and Scope 3 (all other indirect CO2 emissions resulting, for example, throughout the supply chain).


Carbon footprint based on Scope 1, 2 and 3 of the Greenhouse Gas Protocol (GHG)

  • Scope 1 emissions: Direct consumption of fossil fuels accounted for 17% of Swisscom’s total direct energy consumption in 2015 (prior year: 16.6%). Scope 1 CO2 emissions from fossil fuels have fallen by 5.9% since 1 January 2010 to 20,115 tonnes of CO2 eq in 2015, without adjustment for the number of heating days. Vehicle fuel accounted for 53% of this, and heating fuel for 47%. In addition, emissions from refrigerants included under Scope 1 were 503 tonnes (prior year: 271 tonnes).Swisscom does not include emissions from SF6 losses in electrical transformers and stations, as these systems are not controlled by Swisscom.
  • Scope 2 emissions: Swisscom now presents its Scope 2 emissions before and after offsetting. The CO2 emissions from electrical energy consumption before offsetting amounted to 9,271 tons of CO2 eq in 2015 (location-based approach) and 0 tons of CO2 eq after offsetting with market instruments (certificates, market-based approach). Under Scope 2, Swisscom therefore did not emit any CO2 as a result of electricity consumption in 2015, but had a share of 765 tonnes of CO2 from district heating.
  • Scope 3 emissions: Swisscom determined its greenhouse gas emissions in accordance with all Scope 3 categories (1, 2 and 4 supply chains; 3 provision of energy; 5 waste generated in operations; 6 business travel; 7 employee commuting; 8 leased sales outlets; 9 transport to customers; 11 use of the products; 12 decommissioning of the handsets; 15 investments), excluding the following categories: Processing of sold products (cat. 10), downstream leased assets (cat. 13) and franchises (cat. 14). These categories were not relevant, as in 2015 Swisscom did not manufacture any products, did not operate any distribution centres (downstream leased assets) and did not operate any franchises. Swisscom’s Scope 3 CO2 emissions amounted to 437,516 tonnes (prior year: 449,589 tonnes).

Swisscom publishes a climate report and has the report and the related greenhouse gas inventory externally verified. This report is structured in accordance with the ISO 14064 standard. This report not only provides information on CO2 emissions, but also on the effects of the reduction measures implemented. It also calculates the CO2 emissions that can be avoided by companies and residential customers – if they use these myclimate-certified sustainable ICT servicesFinally, the climate report includes a balance sheet of CO2 emissions and savings among customers. The ratio of savings among customers to emissions at the end of 2015 is 0.81, which is slightly better than that of the previous year (0.77).


Swisscom is also involved each year in the Carbon Disclosure Project (CDP). The information gathered through the CDP regarding emissions and Swisscom’s commitment to climate protection can be viewed on the CDP platform. Swisscom continued to be listed in the Carbon Disclosure Leadership Index (CDLI) in 2015. Its score was 98A.
