Air pollution

We monitor air quality throughout the Borough at 12 roadside sites and at 3 monitoring stations.

Our 3 monitoring stations are at:

  • Eaglescliffe School, monitoring for NO2, PM2.5 and PM10
  • Nelson Terrace, monitoring for NO2 and PM2.5
  • Cowpen Depot, monitoring for NO2

During the 2021 monitoring period, we did not report any NOover the annual mean objective at any monitoring location across the Borough.

The most recent data shows that levels have generally increased in 2021 compared to 2020, likely due to the easing of COVID-19 pandemic travel restrictions. However the levels recorded in 2021 are lower across most monitoring locations than those recorded prior to the pandemic demonstrating a continual improvement in air quality levels throughout the Borough.   

This data and analysis has been fully ratified and confirmed by Defra.

Clean Air Day

The campaign is focusing on the fact that cleaning up our air is good for us in many ways: it not only benefits our physical health and the environment, but can also protect our mental and brain health.
