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

To ask the Secretary of State for Environment, Food and Rural Affairs, if he will require developers of construction sites to conduct detailed air quality monitoring to assess compliance with legal and safe levels of (a) air pollution, (b) NOX, (c) PM10, and (d) PM2.5, in response to the findings of the London Assembly Environment Committee’s recent Clean Air for All Londoners report.

Defra currently supports a network of over 500 monitoring sites covering the whole of the UK, measuring concentrations of 13 air pollutants.

In addition to the national UK Air Quality monitoring networks, local authorities, businesses and academics carry out monitoring and modelling of air quality which may pick up more localised air pollution. We have no plans to require construction sites to monitor air quality. However, we continue to encourage all industries to consider improving their practices around air quality.
