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 he has made of the adequacy of air quality levels in Maidenhead constituency.

Local authorities review and assess air quality in their areas and publish an annual report on their actions to improve local air quality including local monitoring data.

The Royal Borough of Windsor and Maidenhead have reported continued reductions in concentrations of NO2 and PM10 over recent years and continued compliance with the Air Quality Objectives set by central Government. The council has begun to monitor local concentrations of PM2.5 and are likely to report on this pollutant later this year; Defra’s modelling for PM2.5 shows that background concentrations are also well below the annual mean Air Quality Objective in this council’s area.

The most recent national air quality compliance assessment for 2023 presented air quality modelling data and measurements from national air pollution monitoring networks across the UK. The assessment was published in September 2024 on Defra’s UK-AIR website. No exceedances were reported of the limit and target values for NO2, PM10 or PM2.5 in the Royal Borough of Windsor and Maidenhead.
