The move is part of UK government efforts to meet a legally binding aim of achieving "net zero" by 2050. That means not emitting more greenhouse gases than are removed from the atmosphere.
Domestic transport – including cars, buses and trains - was responsible for more than a quarter of emissions in 2023, making it the largest emitting sector.
Ministers have committed to banning the sale of new petrol and diesel cars in 2030.
That means all new cars will have to be electric, or hybrid - with both an internal combustion engine and electric motor.
UK drivers will be able to buy new hybrids until 2035.
The EU won't ban sales of new fossil fuel-powered cars until 2035.
