Richmond, a borough in southwest London, has approved a parking-permit pricing scheme based on the carbon-emissions profile of the vehicle being parked. "The new plan would cut charges for owners of compact cars and raise them for drivers of larger vehicles," according to a report from Bloomberg News. "London Mayor Ken Livingstone is considering a similar pay scale for the city's traffic-congestion charge zone."

Hey Toronto, what about testing this out here????

I first wrote about this back in October, when Richmond council was first considering the new sliding-scale parking fee. It's nice to see that they followed through.
