Asked Of: 
The Mayor


How much in percentage terms would an inner London low emission zone (covering the current area of the central and western congestion charging zone) set at a standard equivalent to Phase 3 of the currently proposed London low emission zone, if introduced in 2012, reduce the number of people otherwise exposed in that year to concentrations of nitrogen dioxide (NO2) above the EU annual limit value for NO2?

TfL has not carried out any detailed assessment of the costs and impacts of inner London Low Emission Zones at a standard equivalent to Phase 3 in 2012.

The option of a Low Emission Zone at the proposed Phase 3 standard for either inner London or the extended central London congestion charging zone is not contained within the current consultation draft of the Air Quality Strategy. I am aware that this is one suggestion arising from the consultation and TfL is considering all responses received in the course of assembly and functional body consultation. TfL does not have an estimate of the population exposure reduction in respect of the NO2 Limit Value that would arise from such a proposal. Any such analysis would involve further detailed and complex modelling.
