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

Swisscom follows a clear policy to combat the consequences of climate change and applies the internationally recognised definitions of the Greenhouse Gas Protocol (GHG). It 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).


Swisscom maintains a greenhouse gas inventory according to the ISO 14064 standard:

  • Scope 1 emissions: Direct consumption of fossil fuels accounts for 17.9% of Swisscom’s total direct energy consumption (prior year: 19.9%). Scope 1 CO2 emissions have fallen by 17.5% since 1 January 2010 to 21,380 tonnes in 2014, without adjustment for the number of heating days. Vehicle fuel accounts for 51% of this, and heating fuel for 49%. Scope 1 also factors in emissions from refrigerants of 271 tonnes (prior year: 226 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: The electricity mix used in Switzerland by Swisscom is not generated from fossil fuels and so is free from CO2 emissions. Under Scope 2, Swisscom therefore does not emit any CO2 as a result of electricity consumption, but has a share of 794 tonnes of CO2 from district heating.
  • Scope 3 emissions: Swisscom determined its greenhouse gas emissions in 2014 in accordance with all Scope 3 categories, excluding the following categories: 10 processing of sold products, 13 downstream leased assets and 14 franchises. These categories are not relevant, as Swisscom does not manufacture any products, does not operate any distribution centres (downstream leased assets) and does not operate any franchises. Swisscom’s CO2 emissions according to Scope 3 amount to 449,589 tonnes.

Swisscom publishes its greenhouse gas inventory and has it externally certified in a climate report. This report is structured in accordance with the ISO 14064 norm. This report not only provides information on CO2 emissions, but also on the effects of implemented saving measures. It also calculates the CO2 emissions that can be avoided by companies and residential customers if they use the myclimate-certified ecologically friendly ICT services. Finally, the climate report includes a balance sheet of emissions and reductions. The ratio of reductions to emissions at the end of 2014 is 0.77, which is slightly better than that of the previous year (0.72).

Swisscom is also involved each year in the Carbon Disclosure Project (CDP). The information gathered through the CDP regarding emissions and Swisscom’s work in the protection of our climate is available on the CDP platform. This year, Swisscom was included in the Carbon Disclosure Leadership Index (CDLI) and the Carbon Supplier Climate Performance Leadership Index (SCPLI).
