Motorists turning their backs on petrol and diesel contributed to a 40 per cent national rise in the number of newly registered ultra-low emission vehicles last year.
The RAC said the rise proves an "electric revolution" is underway across the UK – but the Green Party says more needs to be done to ensure a switch to electric motoring is sustainable long-term.
Department for Transport data shows 917 Ultra-Low Emission Vehicles (ULEVs) were licensed to addresses in West Lothian as of September – an 83 per cent increase from 500 a year earlier. Of those, 144 (16 per cent) were registered to companies based in the area, while 773 were privately owned.
In the Falkirk Council area there was a 76 per cent increase from 409 a year earlier. Of those, 176 (25 per cent) were registered to companies based in the area, while 542 were privately owned.
The figures show 83,000 ULEVs made up 15 per cent of all new registrations nationally between July and September last year, when registrations of petrol and diesel cars fell 41 per cent and 66 per cent respectively.
Designed to emit less than 75g of carbon dioxide from the tailpipe for every kilometre travelled, they include battery electric, plug-in hybrid electric and fuel cell electric vehicles.
The sharp year-on-year rise in ULEVs, which incorporated a record 48,000 registrations made in September alone, came despite an overall drop in new car registrations nationally.
Simon Williams from the RAC said the figures were proof of an "electric revolution" accelerating electric vehicles becoming more mainstream.
Mr Williams added: "If petrol and diesel prices continue to stay at near record levels those who can afford to will be increasingly tempted to go electric."
The Government has committed to ending the sale of new petrol and diesel cars and vans by 2030, and ensuring all new sales are "zero emissions at the tailpipe" by 2035.
But Caroline Russell, the Green Party's spokeswoman for transport and healthy streets, said the Government and councils must do more to provide a better network of charging points to ensure switching to electric vehicles is viable and efficient.
She added: "It doesn't matter how cars are powered, they still contribute to traffic deaths, congestion and dangerous air pollution from tyre wear."
Of the ULEVs registered in West Lothian as of September, 534 were battery powered – defined as zero emission. A further 365 were plug-in hybrid electric models, which combine an electric motor with a petrol or diesel engine.
At the same time in Falkirk 468 were battery powered – defined as zero emission.
A further 238 were plug-in hybrid electric models, which combine an electric motor with a petrol or diesel engine.
A Government spokesman said the statistics show drivers are increasingly confident in switching to electric vehicles, adding: "We look forward to seeing this trend continue as we work towards the UK's ambitious net-zero targets."
In 2021, the total number of public chargepoints increased by a third.
The address a vehicle is registered to does not necessarily reflect where it is located, especially for large fleets kept by companies for leasing or rentals.
