Air quality monitoring and reports

Monitoring the air quality in Brent allows us to understand where pollution is worst, and which actions are most effective at reducing it. It is also a legal requirement for us to monitor pollutants in the borough and compare the levels against the UK objectives. You can view pollution data where you live by exploring the below links.

The data collected each year is published in our Annual Status Reports. The most current, and historical reports are available to download below.

Air quality status reports

This is a statutory document which is reported to the GLA each year where the council are required to use a specific format. Please contact us for an accessible version of these reports. You can also download the data via spreadsheet:

Air quality monitoring locations across Brent

To keep track of pollution in the borough, we currently operate a monitoring network made up of four automatic monitoring stations and diffusion tubes across 45 locations. We use these to keep track of nitrogen dioxide, PM2.5 and PM10.

All four of the automatic stations monitor NO2 and PM10. Two of the monitors also monitor PM2.5. The 45 diffusion tube locations monitor NO2 only.  This map shows the location of all active continuous monitoring stations and NO2 diffusion tubes across Brent.
