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

To ask the Secretary of State for Environment, Food and Rural Affairs, which local authorities have breached legal air quality limits in each of the last seven years.

We do not hold compliance data at a local authority level. Defra assesses compliance against EU air quality limit values for 43 regional zones and agglomerations across the UK. World Health Organization guidelines and EU limits are the same for nitrogen dioxide (NO2), but differ for all other pollutants. The compliance assessment is contained in the annual compliance reports which are accessible on the UK-Air Air website:

Air quality data from Defra's national monitoring network is routinely published on the UK-Air website and can be searched by location. In addition, many local authorities monitor air quality at local level and make this data available
