With around 34,200 employees, SBB transports people and goods, providing access to and connecting the country’s centres and regions. A train journey in Switzerland is six times more energy-efficient and produces twenty-seven times less CO2 than a car journey over a comparable route.

Energy and climate

SBB aims to halve its greenhouse gas emissions by 2030. Its comprehensive programme for achieving this includes cutting energy use, using renewable energy and replacing climate-damaging industrial gases, for example in air-conditioning systems. In 2022, SBB increased its energy efficiency by 17 per cent compared to 2010, saving 539 gigawatt hours of energy, equivalent to the electricity demand of over 130,000 households. In order to underline its commitment, in 2022 it joined the Science Based Targets initiative (SBTi).


Under the EEC initiative, SBB has pledged to meet the following targets:

1. Increasing energy efficiency

Benchmark: 2018/2019

  • Target for 2026: +6%
  • Target for 2030: +10%

2. Switching to renewable energies

Thermal energy and fuels

  • Target for 2026: 32% renewables
  • Target for 2030: 50% renewables


  • Target for 2026: 100% from renewable sources

3. Producing green power


  • Production in 2021: 2.3GWh
  • Target for 2026: +17.7GWh
  • Target for 2030: +10GWh


Like all the participants, SBB has undertaken to implement the joint measures. In addition, SBB is also implementing the following individual measures:

1. FLIRT rolling stock energy-saving package
2023: –6,700MWh/year

2. More efficient production at Ritom hydroelectric power station
2024: 1,300MWh/year electricity production

3. Modernisation of IC2000 cars
2024: –12,500MWh/year

4. Optimisation of railway access and track area lighting
2025: –10,100MWh/year

5. Use of up to 25% HVO biodiesel (synthetic diesel made from hydrogenated vegetable oils)
2025: up to –5,100t CO2/year

6. Energy-optimised stabling of RV-Dosto regional double-decker trains
2026: –4,500MWh/year

7. Refurbishment of Am843 shunting locomotives
2029: –8,800t CO2/year

8. Modernisation of ICN cars
2027: –2,300MWh/year

9. Use of natural coolants
2030: –500t CO2/year

10. Conversion of gas point-heating systems to renewable solutions
2030: –2,600t CO2/year

11. Replacement transformers for traction power supply
2030: –15,600MWh/year
