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

To ask the Secretary of State for Environment, Food and Rural Affairs, when she expects the Joint Air Quality Unit to issue evaluation guidance to Local Authorities on how NO2 compliance will be determined for the purpose of clean air zones.

The Joint Air Quality Unit is working closely with local authorities that are part of the NO2 Programme. A comprehensive suite of guidance has already been issued to Local Authorities on 28 June, covering a range of issues including how JAQU will determine the success of Local Authority NO2 Air Quality Plans. The Joint Air Quality Unit has also held a workshop with Local Authorities to go through this guidance on 5 July 2023.
