By what percentage would the worst legal breaches of EU limit values for each of PM10 (daily) and NO2 (annual and hourly) be reduced if a current Berlin-style low emission zone was implemented for each of: (a) the central and western congestion charging zone; and (b) inner London defined as being inside the north and south circular roads?

Modelling shows that measures already underway, including the London-wide LEZ, will allow PM10 limit values to be achieved across Greater London by 2011. However, NO2 is a problem across much of Greater London, not just central and inner London. That is why my draft Air Quality Strategy includes proposals to reduce NOx emissions across the Capital, including the introduction of a NOx standard to the current London-wide LEZ from 2015, though this will require assistance from the Government.

Given that my focus is on reducing emissions across the whole of London, I do not consider that inner or central London schemes would represent good value for money due to the high set-up and operating costs for TfL and compliance costs for vehicle owners.
