Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, what information his Department holds on the mean average value for nitrogen dioxide levels by parliamentary constituency in 2015; and if he will make a statement.

We do not hold the specified information by Parliamentary constituency. Information on modelled annual mean nitrogen dioxide concentrations for 2015 by local authority is available via the UK Ambient Air Quality Interactive map on our website at: uk-air.defra.gov.uk/data/gis-mapping.
