The British government wants to ban the sale of new diesel and petrol cars as early as 2030. Prime minister Boris Johnson announced in February that he would ban new cars with an internal combustion engine by 2035. According to the British business newspaper, however, this ban will be in place five years earlier.

Johnson is expected to announce the revised plans next week at a speech focusing on sustainability policy.

The ban would not apply to hybrid cars by 2030, which are likely to be banned five years later.

The sale ban would have a huge impact on car sales in the UK. At present, diesel and petrol cars account for almost three quarters of the total new car sales.
