After writing about the new “low-emission” zone in London, I was fascinated to read about a scheme for normal cars to make the Congestion Charge variable according to the car’s emissions.

The idea is, that the current charge of 8GBP could rise up to as much as 25GBP for vehicles that have high emission rates, but on the other hand the charge could be reduced down to nothing for low-emission cars.

I’m note sure that everyone will approve, but I’ll be keeping an eye on the new tariffs to see whether bio-ethanol cars belong to the “free” category!
