Operation and Vehicle Optimisation

PostBus consumes about 42 million litres of diesel annually in Switzerland, which is why it supports easing the burden on the environment from fuel emissions and promotes the reduction of fuel consumption. Examples of this include:

  • Pioneering work with carbon-neutral fuel cell Postbuses
  • Procurement of hybrid vehicles
  • Efficient turnaround cycles
  • Training of drivers in eco-drive techniques
  • Support for drivers through regular monitoring by eco-coaches

Emission standards

Since January 2014, only vehicles that meet the emission standard EURO 6 can be operated in Switzerland. In mid-2014, the proportion of Postbuses that meet the strict emission standards Euro 5, EEV or Euro 6 is already 44% of the total fleet. The older vehicles that do not meet modern emission standards are primarily replacement vehicles and are mainly used in exceptional situations. The majority of passenger services are provided with vehicles that meet at least Euro 3.

Accompanying measures

Since the end of 2013, 16 eco-coaches have been at work accompanying drivers in their everyday work, analysing their driving style together with them, and making suggestions for improvement on the road. Before they can receive coaching, drivers must have already taken an Eco-Drive course and be familiar with the principles of eco-driving. The Eco-Drive courses are offered by the PostBus driving school, and almost all drivers have attended this one-day course in the last five years.

As a further measure, fuel consumption figures are evaluated periodically.  To encourage positive consumption trends, the evaluations are regularly presented to staff, and a portion of the savings are passed on to the drivers.
