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 2020 monitoring period, we did not report any NO2 over the annual mean objective at any monitoring location across the Borough. The highest amount that was recorded for 2020 was also lower than that of 2019.

The general trend for air quality in Stockton-on-Tees is that levels have improved year-on-year from 2018 to 2020. This data and analysis has been fully ratified and confirmed by Defra who note the assessments as examples of best practise.
