Air Pollution: Pollution Control

Question: To ask the Secretary of State for Environment, Food and Rural Affairs, what assessment her Department has made of whether examples of best practice exist in England to achieve compliance with legislation and regulation to improve local air quality in each of (a) ambient air and (b) indoor air.

Answer: Defra supports local authorities in implementing their statutory air quality duties by providing both resources and practical tools. A key example is the Air Quality Hub, which enables local authorities to collaborate, share best practice, and access guidance, case studies, and training materials. This platform strengthens alignment between local delivery and national objectives by ensuring that evidence, lessons learned, and emerging policy priorities are shared consistently across the local authority network.
