CNG buses on test

Natural gas is a fuel that has advantages over diesel or petrol: It emits less CO2, less particulate matter and is, by the way, also quieter. For all these reasons, the urban municipality of “Porte de l'Isère” (CAPI) will put gas-powered buses into service. In the long term, this type of vehicle could be the only one with combustion engine to be allowed in cities having low emission zones.
