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

To ask the Secretary of State for Environment, Food and Rural Affairs, pursuant to the Answer of 21 January 2025 to Question 23346 on Property Development: Air Pollution, how many new developments and dwellings currently undertake air quality assessments; and when such are assessments required.

All developments subject to an Environmental Impact Assessment are required to undertake air quality assessments. Air quality assessments may also be required for developments where national assessment indicates that relevant limit values for air pollutants have been exceeded or are near the limit, or where the need for emissions reductions has been identified.

The information regarding how many new developments and dwellings currently undertake air quality assessments is not collated centrally.
