The sale of new petrol or diesel cars will be banned in 2030, Boris Johnson is set to announce.
According to a report in the Financial Times, the Prime Minister will bring forward the ban as part of a wider range of green initiatives due to be unveiled this week.
The policy was initially due to come into force in 2040 and had already been brought forward to 2035.
The new development will put enormous pressure on the car industry, according to Nicholas Lyes, head of roads policy at the RAC.
He said firms now faced a “monumental challenge” to change their production lines and charging infrastructure for electric vehicles will need to be expanded at “incredible pace” to cope with the surge in demand.
Figures published last week by the Department for Transport showed there are now nearly 20,000 charging points in the UK, an 18 per cent increase this year.
Mr Lyes said: “We believe many more rapid charging devices are needed in order to give drivers the confidence that they can make longer journeys in a convenient and time efficient manner.
“While many people, especially those with off-street parking, will charge their vehicles overnight at home, this won’t be possible for everyone so access to a reliable national charging network is vital to make the process of recharging simple and convenient.”
He added that the cost of electric vehicles remains prohibitively high for most people to afford when compared to conventional vehicles.
This will begin to change as more come into the second-hand market.
The Department for Transport declined to comment on the reports, but the Transport Secretary is understood to have been supportive of bringing the ban forward from 2040.
