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 implications for his policies of the Mayor of London’s report entitled London-wide Ultra Low Emission Zone One Year Report, published on 7 March 2025.

Poor air quality continues to be the biggest environmental risk to human health. Whilst responsibility for air quality and transport is devolved in London, we welcome the progress made there to address air pollution and improve people’s health. Local and devolved authorities are best placed to determine the most effective route to improving air quality in their cities. We are committed to working with them to improve the air we breathe.
