Owners of cars emitting more than 225g/km of carbon dioxide will pay a £25-a-day congestion charge to enter London from October 27.
In addition, if you drive a car registered before September 2001 with an engine bigger than 3000cc, you’ll also be charged £25.
London mayor Ken Livingstone also confirmed that owners of cars that emit less than 120g/km of CO2 will have the congestion charge waived.
Just two per cent of cars using the zone at present are in tax bands A and B, which will be free, although this figure is expected to rise significantly.
'Nobody needs to damage the environment by driving a gas-guzzling Chelsea Tractor in central London,' said Livingstone. 'The CO2 charge will encourage people to switch to cleaner vehicles, or public transport.'
'Those who choose to carry on driving the most-polluting vehicles will help to pay for the environmental damage they cause. This is the "polluter pays" principle.'
Livingstone is the architect of the Mayor’s Climate Change Action Plan, which aims to reduce London’s CO2 emissions by 60 per cent by 2025.
