There are two automatic monitoring stations in Newport:  

  • A - St Julians - monitors for nitrogen dioxide, nitrogen oxides, polyaromatic hydrocarbons (PAH), benzene, PM10 and PM2.5
  • B - M4 unit - (operated by Welsh Government) monitors for nitrogen dioxide, nitrogen oxide and ozone.

Find data from these units on the Welsh Air Quality website 


If you are considering to submit a planning application in Newport, you may need to consider air quality - a detailed air quality assessment is rarely needed.

View our Supplementary Planning Guidance for Air Quality for further information.

We encourage sustainable travel principles in all development schemes from concept to build.

Cycle paths and storage, pedestrian routes, electric vehicle charging points and much more could be considered to help reduce carbon emissions, reduce road traffic noise and improve air quality.

Look at how people travel into and out of your development and not just by car.
