The Government notes the high reading for nitrogen dioxide concentrations from the monitoring station in Hillingdon. It cannot be concluded from the report that Hillingdon has the second highest concentrations of nitrogen dioxide in the EU, only that it has the second highest reading of the urban and suburban monitoring stations analysed. It should be noted that the placement of monitoring stations can greatly affect the reading levels. The Hillingdon urban background station is located 30 metres from the M4 motorway and is therefore affected by traffic emissions from this very busy road.
We have noted the conclusions of the Air Quality in Europe report published by the European Environment Agency. We are committed to working towards full compliance with European Air Quality Standards and are investing significantly in transport and other measures that will contribute to reductions in local air pollution.
