Swisscom’s CO2 emissions

Swisscom maintains a greenhouse gas inventory, publishes its emissions according to recognised standards (ISO 14064) and has these verified externally. 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 15% of Swisscom’s total direct energy consumption in 2016 (prior year: 17%). Scope 1 CO2-equivalent emissions from fossil fuels have fallen by 22.0% since 1 January 2010 and totalled 19,837 tonnes of CO2-equivalent in 2016, without adjustment for the number of heating days. Vehicle fuel accounted for 55% of this, and heating fuel for 45% . In addition, emissions from refrigerants included under Scope 1 were 220 tonnes (prior year: 503 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-equivalent emissions from electrical energy consumption before offsetting amounted to 9,576 tonnes of CO2-equivalent in 2016 (location-based approach) or 0 tonnes of CO2-equivalent after offsetting with market instruments (i.e. certificates, market-based approach). Under Scope 2, Swisscom therefore did not emit any CO2 as a result of electricity consumption in 2016, but had a share of 826 tonnes of CO2-equivalent 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 (category 10), downstream leased assets (category 13) and franchises (category 14). These categories were not relevant, as in 2016 Swisscom did not manufacture any products, did not operate any distribution centres (downstream leased assets) and did not operate any franchises. Swisscom’s CO2-equivalent emissions according to Scope 3 amounted to 439,791 tonnes (prior year: 437,516 tonnes).

Swisscom publishes a climate report and has the report and the related greenhouse gas inventory externally verified. The report is structured in accordance with the ISO 14064 standard. The report not only provides information on CO2 emissions, but also on the effects of the reduction measures implemented within the company. It also calculates the CO2 emissions that can be avoided by corporate customers and residential customers if they use myclimate-certified sustainable ICT ­services. Finally, the climate report includes a balance sheet of CO2emissions and savings among customers. The ratio of savings among customers to emissions improved slightly over the previous year (0.81) to end the year at 0.99.


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 was again listed on the A-List and in the Carbon Disclosure Leadership Index (CDLI) in 2016.
