Answered By: 
The Mayor

Written response from the Mayor The focus areas are a sub-group of locations estimated to exceed the NO2 limit values in 2011 and 2015 (based on modelling for the Mayor's Air Quality Strategy) and are areas with high levels of human exposure.

To understand the causes of the high concentrations various data was collated. The average concentration was not included as this did not provide any additional information to help target action in these areas. However, as part of the publication of the London Atmospheric Emissions Inventory 2010 emissions data, GIS files, images and the full concentration modelling datasets are available on the London Datastore. This gives individuals and organisations access to the information needed to answer questions relating to air pollution in London.
