Air quality

Air quality management areas

Air quality in Warrington is generally good but there are areas close to major roads that do exceed the national limit for mean annual nitrogen dioxide.  

Where there's a potential risk that this limit might be exceeded, an Air Quality Management Area (AQMA) must be declared.

Approximately 1.8% of the population in Warrington live in AQMAs.

There are current two AQMAs in Warrington:

  • Motorway AQMA around the M56, M6 and M62
  • Warrington AQMA, around the town centre and main arterial roads
