London Atmospheric Emissions Inventory (LAEI) 2019 Air Quality Focus Areas

According to the LAEI 2019, there are 160 Air Quality Focus Areas in London. The Focus Areas are locations that not only exceed the EU annual mean limit value for NO2 but are also locations with high human exposure. They were defined to address concerns raised by boroughs within their Local Air Quality Management (LAQM) review process and forecasted air pollution trends. This is not an exhaustive list of London’s hotspot locations, but where the GLA believe the problem to be most acute.
