To ask the Secretary of State for Transport, what steps he is taking to ensure local highway authorities are tackling roadside air pollution generated by motor vehicles.

The Government published its plan for tackling roadside nitrogen dioxide (NO2) concentrations in 2017. This has been underpinned with £883m of dedicated funding to help local authorities develop and implement local NO2 air quality plans and support those affected by these plans. This sits alongside significant investment to support the transition to cleaner, more sustainable transport, including funding to kickstart a cycling and walking revolution and £320 million invested so far to support zero emission buses as part of a step-change in investment into bus services.
