In a welcome move, Richmond has extended it's variable CO2-based parking charges to all car parks and parking spaces in the London borough.
Charges will rise by 25% for vehicles producing more than 180g of CO2 per km, and reduced for the cleanest cars.
BBC News transport correspondent Tom Symonds said the move "is the most radical attempt so far to link parking charges to carbon emissions. "
In a recent RAC poll, drivers overwhelmingly favored higher penalties for the most polluting cars, while they also welcomed more incentives for less polluting cars.
