2015 NO₂ projections data (2013 reference year)

« Return to NO₂ Air quality plans

Projections for concentrations of nitrogen dioxide (NO₂) and oxides of nitrogen (NOx) across the UK in 2020, 2025 and 2030 have been calculated as part of a Pollution Climate Mapping (PCM) model assessment for the development of the 2015 Air Quality plan: Improving air quality in the UK: Tackling nitrogen dioxide in our towns and cities.

The baseline projections represent the projected concentrations assuming no further action beyond the air quality measures that were committed by the reference year (2013). A GIS shapefile containing baseline projected roadside NOx and NO₂ concentrations for approximately 9,000 road links may be downloaded via the link below. This file also includes background NOx and NO₂ concentrations, which have been modelled at a 1x1km resolution for each of the road links.

The plan scenario projections represent the projected concentrations assuming additional measures are implemented, as outlined in the 2015 Air Quality Plan for NO₂. A GIS shapefile containing projected roadside NOx and NO₂ concentrations based on the 2015 plan for NO₂ at approximately 9,000 representative roadside locations may be downloaded via the link below.

The projected annual mean NOx source apportionment for the projected baseline situation is also available to download for each zone via the links below.
