London is about to have the world’s largest pollution charging area, as the capital’s outer suburbs are added to the inner city Ultra Low Emission Zone - ULEZ. Drivers of vehicles that don’t meet emissions standards will be charged £12.50 a day – with motorists facing the threat of a £180 fine if they don’t comply.ULEZ expansion was widely regarded as a key factor in the Conservatives holding onto Boris Johnson’s old Uxbridge seat in a recent by election; and unlike in other English cities the government is refusing to fund a scrappage scheme for non compliant cars. That's led to claims by London Mayor Sadiq Khan that they are weaponising air pollution.
