UK Air Quality Legislation

Part IV of the Environment Act 1995 required the Government to produce a National Air Quality Strategy containing standards and objectives for improving ambient air quality in the UK. This strategy was published in January 2000 and updated in 2003 and is included within the Air Quality Regulations 2000 & (Amendment) Regulations 2002.

This strategy was set up to enable the government to review air quality and to assess whether the air quality standards and objectives it sets out are being met. The strategy uses health based standards as a framework to control the levels of seven designated air pollutants that are known to have adverse health effects. These are: Benzene, 1,3 Butadiene, Carbon Monoxide, Lead, Nitrogen Dioxide, Particles (PM10), and Sulphur Dioxide, to be achieved between 2003 and 2008. These levels also ensure the UK meets its responsibilities under the European Union's Air Quality Framework and Daughter Directives.
