Kerry County Council has become the first local authority to trial the use of a carbon neutral truck.
The vehicle, supplied by T Nolan and Sons Scania dealership in Castleisland, was powered by compressed natural gas from Gas Networks Ireland.
During the two-week trial, Kerry County Council used the zero carbon, heavy goods vehicle to move road salt from Tipperary to Listowel.
Gas Networks Ireland has also announced a €2.9m CNG Vehicle Grant scheme to support the purchase of gas-powered vehicles for use in the transport sector.
Declan O'Sullivan, CNG Program Delivery Manager at Gas Networks Ireland, says natural gas is 20% cleaner and 35% cheaper than diesel.
