To ask the Secretary of State for Health and Social Care, what steps his Department is taking to help tackle the public health risks associated with high levels of nitrogen oxide pollution from diesel vehicles.

Despite significant progress, air pollution remains a significant environmental threat to human health. Leading our Health Mission, the Department of Health and Social Care is working across Government, including with the Department for Transport, to promote a reduction in the health harms of air pollution.

Tackling the public health risks associated with air pollution involves reducing concentrations of pollutants where people live, work and play. Local authorities have an important role in identifying and implementing the local measures needed to achieve legal air quality limits and clean up the air we breathe. The NO2 programme has provided £575 million to support local authorities to address nitrogen dioxide pollution and achieve compliance with legal limits in the shortest possible time, supporting measures such as Clean Air Zones, traffic management improvements and vehicle upgrade schemes, and recently agreeing Greater Manchester’s £86 million Clean Air Plan.
