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

To ask the Secretary of State for Environment, Food and Rural Affairs, what recent assessment his Department has made of the potential merits of aligning the UK's PM2.5 air quality targets with the World Health Organisation’s 2021 guidelines.

The revised Environmental Improvement Plan is due to include further details on the PM2.5 air quality targets set under the Environment Act 2021. The World Health Organisation (WHO) air quality guidelines will continue to inform our evidence when considering future targets.
