Air quality

Data, reports and Bristol's plans for clean air.

Clean air is essential for health and helps to make the city a pleasant place to live. We monitor air quality around the city and are working to improve it.

Clean Air Zone

We launched a Clean Air Zone (CAZ) in November 2022 to help lower nitrogen dioxide pollution to safer, legal levels. For more information, visit Bristol's Clean Air Zone.

Since the introduction of the CAZ, average annual nitrogen dioxide levels have fallen by 20% inside the zone and almost 17% outside of the zone.

Monitoring and reporting on air pollution

Every year we must tell the Government what we’re doing to reduce pollution and meet legal limits. Most places in Bristol now meet those limits, except for a few locations in the city centre.

Find the most recent results and all the place where we measure air pollution on our Air Quality Dashboard.

The documents we submit to the Government about air quality in Bristol are called Annual Status Reports. Our latest Annual Status Report (2025) contains a summary of all air pollution monitoring data for 2024. 2024 was the second full year the Clean Air Zone was in operation.

The document also includes data from the previous 5 years as well as:

  • information on how air pollution harms our health
  • what we’re doing to reduce air pollution in Bristol
  • ways people in Bristol can reduce how much air pollution they make and how much they breathe in
