Todays Air Quality In Liverpool
Here is todays air quality in Liverpool along with monitoring data and information about the current and historic levels of air pollution.
What have the air pollution levels been in Liverpool 2025
The weather has the biggest influence on NO2 concentrations in the short term and the weather in January 2024 and February 2024 was relatively cold. Therefore, the monthly average nitrogen dioxide (NO2) concentrations have remained high between January and February 2025.. Warmer weather in spring and summer results in NO2 levels decreasing slightly. T
The legal limit for NO2 is 40 µg/m3 when averaged over one year. The sites at Edge Lane, Speke Road, Everton Valley, Clayton Square and the Speke AURN are all significantly below this limit so far in 2025. They were also below this limit in 2024. .
At Walton Vale and Hunter Street, the monthly averages for 2025 are currently around the annual limit value for NO2. This is likely due to the large amounts of traffic at these location. Liverpool City Council is currently implementing traffic control measures in these locations as part of the Liverpool Clean Air Plan.
.At Lime Street and Pembroke Place, the monthly averages for 2025 are currently exceeding the annual limit value for NO2. This is likely due to the large amounts of traffic at these location. Liverpool City Council is currently exploring different options to reduce air pollution in these locations as part of the Liverpool Clean Air Plan.
The table below shows the nitrogen dioxide concentrations in microgrammes per metre cubed (µg/m3)

Why is pollution often classified as low everywhere?
Often air pollution levels in most areas of Liverpool are sufficiently small to be classified as low according to the Air Quality Index. When this index was created these levels were considered unlikely to cause any adverse health effects. There is currently debate about whether there is any safe level for these pollutants and the Air Quality Index may be revised in the future. Liverpool City Council do not believe that the Air Quality Index is the best way to classify air pollution level but we have included it on this website because it is used at a national level and by other local authorities
Why is there no data from one of the monitoring stations?
The following issue has been noted on the monitoring network and Liverpool City Council and its partners are working to restore data as soon as possible:
- Edge Lane – Electrical Power Failure – July 2025
