What is the LAQN?

LAQN stands for the London Air Quality Network which was formed in 1993 to coordinate and improve air pollution monitoring in London. The network collects air pollution data from London boroughs, with each one funding monitoring in its own area. Increasingly, this information is being supplemented with measurements from local authorities surrounding London in Essex, Kent and Surrey, thereby providing an overall perspective of air pollution in South East England, as well as a greater understanding of pollution in London itself.

• You can see reports about London air quality from 1993 onwards.
• This network is operated by the Environmental Research Group (ERG) of Imperial College London.
