Environmental Research Group

The Environmental Research Group (ERG) is part of the School of Biomedical and Health Sciences at King's College London and is a leading provider of air quality information and research in the UK. In 1993, ERG created the London Air Quality Network (LAQN) in conjunction with the London Boroughs and Regional Health Authorities - this was the UK's first regional monitoring network. LAQN compiles information about air quality in and around Greater London. Measurements are collected either hourly or twice daily from continuous monitoring sites, processed and checked then placed on the LAQN website with an hourly update, which shows the latest pollution levels across the capital.
