Cars made before 2005 may have to pay an additional charge for entering the congestion zone in London, under proposals put forward by the mayor.
Diesel cars could have to pay an additional charge to come into inner London by 2019 and buses should be retrofitted to meet European standards.
The mayor said they must act because nearly "9,500 Londoners" a year were dying from respiratory problems.
[...]Announcing his plans on the 60th anniversary of the Clean Air Act, the mayor also wants to:
Charge £10 for the most polluting vehicles in the Congestion Charge Zone. This will be on top of the current congestion charge
Bring in the Ultra Low Emission zone - where all vehicles must meet exhaust emission standards or face a charge - a year earlier in 2019 and extend it to the North and South Circular by 2020
Operate the cleanest buses in the dirtiest parts of London by creating "clean bus corridors"
