CO2 based CPZ charges

Barking & Dagenham Council is considering tiered CPZ parking charges based on the CO2 emission rating of cars, following the lead from a few other London councils. The Barking & Dagenham Post (25 April) quoted interviews with two people - one in favour of protecting the planet whilst not being against "gas-guzzlers" as such and another vehemently against, on two grounds, one of which was that "it's a free country" and the council shouldn't tell people what car to drive. Not a terribly convincing argument as it ignores the council's role in trying to protect the planet.
