PostBus is the largest public transport bus company in Switzerland. In 2022 it had around 3,000 employees and transported 156 million passengers country-wide. PostBus’s vehicles run on 911 different lines, service around 11,270 stops and each day cover a distance equivalent to nine times the circumference of the globe.

Energy and climate

In the area of energy and climate, PostBus is working on switching its fleet to alternative, fossil-free drive systems. By the end of 2024, PostBus plans to put a total of 100 electric buses on the roads. By 2030 this number should increase to 1,000, and by 2040 at the latest, PostBus’s entire fleet, which currently numbers 2,300 vehicles, should be climate-friendly. In order for this transformation to happen, PostBus is dependent on the cantons continuing to purchase its services.


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

1. Increasing energy efficiency

Benchmark: 2021

  • Target for 2026: +5%
  • Target for 2030: +20%

2. Switching to renewable energies

Thermal energy and fuels

  • Target for 2026: 3% renewables
  • Target for 2030: 6% renewables


All PostBus’s electricity already comes from renewable sources.

3. Producing green power


  • Production in 2021: 8.8GWh
  • Target for 2030: 26MWp

This data applies to the entire Swiss Post Group.


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

1. Net zero from 2040
Group target for 2030: Swiss Post’s in-house operations to be climate-neutral (emissions to be reduced by 42 per cent compared with 2021, the remaining emissions to be offset)

2. Buses using alternative drive systems
2030: +900 battery buses and fuel-cell buses
