Actually the first 32 public transport buses are taken in operation with upgraded biogas (green certificates), an other 13 buses will follow this summer. Until early 2010, a total of approx. 70 gas driven buses should be in operation. The final goal is the replacement of all 100 diesel buses currently in operation.

On top, a program will be initiated to promote the utilisation of private light duty gas vehicles and taxis. The actions will include education of car workshop collaborators and sales managers. Subsidies will be given for the additional cost of a NGV and for the support of the installation of pumping stations. Five pumping stations are already in operation (actually on natural gas). Two more are planned in Berne and some additional ones in the seven regions where ewb provides gas until 2008.

The gas produced by the WWTP is not enough to operate the 70 buses available in 2010. It is planned to increase gas production with two measures: In a first step kitchen and restaurant waste will be fed to the digester of the WWTP. In a second step an additional digester for source separated waste might be built.

In the nineties a first approach to introduce selective collection of source separated waste has failed due to pure separation quality in the inner city. It will be a challenge to re-introduce the collection system to operate a special digester.
