Overview

London Eye at Night

The London Air Quality Network (LAQN) was formed in 1993 to coordinate and improve air pollution monitoring in London. At the end of 2007, thirty one London Boroughs were supplying data to the LAQN.

Increasingly, these data are being supplemented by measurements from local authorities surrounding London, thereby providing an overall perspective of air pollution in South East England.

The LAQN is facilitated by the Association of London Government on behalf of the thirty-three London Boroughs and is operated and managed by the Environmental Research Group (ERG) at King's College London. Each borough funds monitoring in its own area.

The core LAQN activities are funded by ERG itself. The Department of Environment, Food and Rural Affairs (Defra) funds ERG to operate the Marylebone Road site and to maintain eight of the LAQN sites as affiliate sites to the UK Automatic Urban and Rural Network (AURN). This Defra support assists the operation of the overall LAQN.

To understand air pollution in London it is necessary to understand air pollution in the surrounding area, and vice-versa. The LAQN contains sites in Essex, Kent and Surrey. A more complete picture of air pollution in South East England can be obtained from the combined results of the LAQN and other regional monitoring networks in the south east.
