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

To ask the Secretary of State for Environment, Food and Rural Affairs, what assessment he has made of the potential merits of devolving powers to the Greater London Authority on the regulation of emissions from non-road mobile machinery.

Defra officials regularly have discussions with the Mayor’s office on a range of issues relating to air quality, including their experience of regulating emissions from non-road mobile machinery in London.

We will publish a Clean Air Strategy this year setting out how we will work towards meeting our ambitious targets for reducing air pollution by 2020 and 2030, and are considering a range of options as part of that work.
