Air Quality Reports for Government
Under the Environment Act 1995, we have a duty to review air quality within the district to ensure it meets the objectives set out in the Air Quality (England) Regulations 2010.
As part of that duty, we produce regular reports for the Department for Environment, Food and Rural Affairs (DEFRA) for approval. You can download and read each of these reports on the right-hand side of this page.
Where compliance with such objectives is unlikely, then, as a local authority, we're required to declare an Air Quality Management Area (AQMA). You can find out more about AQMAs on DEFRA's website.
The Winchester Town area was subject to an AQMA from 2003 to 2025 and, as part of that, we were required to produce an Air Quality Action Plan (written in 2006 and updated in 2017), which you can download and view to the right of this page. Following the lifting of the AQMA in 2025, there are currently no AQMAs active in the Winchester district.
