Question to the Department for Transport:

To ask the Secretary of State for Transport, what steps Highways England is taking to reduce levels of nitrogen dioxide on the strategic road network which exceed statutory limits.

Highways England are supporting the uptake of electric vehicles by working to ensure that 95 per cent of the strategic road network will have a chargepoint every 20 miles.

Highways England have also been exploring and testing a range of measures and innovative products as part of their programme of air quality research. They have evidence that tall barriers can reduce concentrations of NO2 for the residents closest nearby, and they are progressing with work to see how these could be installed on the network. This work is underpinned by their £100m Air Quality Designated Fund.
