UK Air Quality Regulations

Air Quality Management Areas

Local authorities must declare AQMAs where pollution exceeds national objectives. Over 700 AQMAs exist across the UK, primarily for NO2 from road traffic.

Clean Air Zones

Several UK cities have introduced Clean Air Zones charging high-polluting vehicles. London's ULEZ, Birmingham, Bristol, and Bradford all have active zones.

National Objectives

UK targets include annual mean NO2 of 40 µg/m³ and PM2.5 of 10 µg/m³ by 2040. Many urban areas currently exceed these limits.
