More monitoring is always beneficial and the existing monitoring network was expanded at the start of 2018 to support monitoring and evaluation of the Clean Air Plan. However, we already have a good picture of the existing air quality problem in Bristol from the extensive monitoring network in the city, which includes real-time monitoring and diffusion tubes. The evidence we have already makes it quite clear that action is needed to tackle poor air quality. Details of the existing data are provided in the Air Quality Annual Status Report which can be found here.

Citizen sensing, where citizens use low-cost monitors to take their own measurements of air quality,  can often be to raise awareness about air pollution, but the data gathered cannot be used by BCC because the quality of the data is not high enough.
