How we check air quality

We have a legal obligation to review and assess air quality across the county, as set out in Section 82 of the Environment Act 1995.

How is air quality reviewed and assessed?

We complete an annual review and assessment to determine whether specific areas of the county meet national air quality standards and EU limits for various pollutants such as carbon monoxide and nitrogen dioxide and particulates (pollutants from road traffic emissions). A full list of pollutants which are reviewed and assessed and the National Air Quality Objectives is available:

Reporting air quality standards

We must carry out an air quality review and assessment and report on the status of air quality across the county to the Department for Environment, Food and Rural Affairs (DEFRA) annually. The Annual Air Quality Status report will provide:

  • A summary of progress of the implementation of the air quality improvement measures within an Air Quality Action Plan (AQAP);
  • The details of air quality monitoring data for the previous year.

The most recent air quality review and assessment report can be downloaded here:

What happens if air quality standards are exceeded?

Once we are satisfied that the outcome of monitoring and detailed assessment work and there is a likely breach of an air quality objective, then we must declare an Air Quality Management Area (AQMA).

Once declared, we must then work with local residents, partners and others such as transport users and providers, to agree an action plan to improve air quality in the area covered by the AQMA. The action plan is a detailed document that sets out proposals to improve air quality in a variety of ways. These may include transport planning, land use, energy management, healthy living and environmental initiatives.
