Yet again the low paid who cannot afford a modern car get hit in the pocket.
Drivers of older, more polluting vehicles will have to pay almost twice as much to drive in central London.
Mayor Sadiq Khan's ã10 T-Charge, which mainly applies to diesel and petrol vehicles registered before 2006, has come into force.
It covers the same area as the existing congestion charge zone, bumping up the cost to ã21.50 for those affected.
Opponents said the scheme would "disproportionately penalise London's poorest drivers".
The measure is the latest attempt by Mr Khan to improve air quality in the capital and according to the mayor's office, will impact 34,000 motorists a month.
