In your answer to my question 2216/2010 you once again fail to address the problem of meeting the nitrogen dioxide margins of tolerance, despite recognising the scale of the problem in your answer to my question 2218/2010. What emergency measures did you consider and what action did you take to meet the margins of tolerance at the 20 sites which provisional six-monthly figures suggested could be in breach of that target?

It is expected that next year the Government will submit an application to the European Commission for a time extension to 2015 for the NO2 limit values. The GLA will assist the Government in preparing that application. Should the Commission approve the time extension, the Government will have a requirement to meet a margin of tolerance in the period up to 2015. The measures included in my draft Air Quality Strategy will help ensure that the margin of tolerance is met, though NO2 is a problem in urban areas across the country, so the Government will also have to put in place measures that will improve air quality in London. Since NO2 concentrations are high across much of Greater London, the measures in my draft Strategy aim to reduce emissions across the capital. However, TfL and the GLA will work with boroughs to develop possible measures to reduce concentrations at NO2 priority locations.
