There is an interesting thread here, CM:

This deals with another of the Mayor's wonderful plans and I referred to the "Low Emissions Zone" in one of my responses.
Many people may not realise just how far out the "Low Emission Zone" stretches. Unlike the so-called Congestion Zone it encompasses almost all of the Greaer London Area, which reaches out near enough as far as the M25 in most directions.
I'm afraid that your concerns will fall on deaf ears (if they fall upon any ears at all).
