Replacing Swansea Council's vans and lorries with electric or other low emission power vehicles could cost as much as £55 million, a meeting was told. The council has 945 vans, lorries and other vehicles, of which 105 are fully electric and 12 hybrid.
The authority is aiming for a "net zero" fleet by 2030. This would mean its vehicles would almost entirely be ultra low-emission, with the emissions from diesel ones offset in other ways.
Mark Barrow, the council's fleet manager, told councillors on a scrutiny panel that the scale of the challenge was "very, very significant" and that the "diesel by exception" approach was becoming incredibly difficult due to volatile market conditions. He said the £55 million price tag was very much an indicative estimate, though.
