Truro Air Quality

Truro Air Quality Management Area

We have been monitoring nitrogen dioxide levels in Truro for several years.  The biggest source of nitrogen dioxide is the exhaust gases from cars and lorries travelling on the A390.

Our monitoring has showed that air pollution levels in Truro are higher than they should be and a Detailed Assessment of air quality was commissioned. This report confirmed poor air quality at several locations along the A390, primarily at Highertown and Tresawls Road as well as the B3284 Kenwyn Road.  

It was therefore concluded that an Air Quality Management Area (AQMA) should be declared. Following a public consultation in early 2015, the AQMA was formally declared on 1 July 2015. The Council has decided that the entire city should be declared as an AQMA due to higher pollution levels being found in several ‘hotspots’. The Map of the Truro Air Quality Management Area shows the boundary.

We have worked with our colleagues and partners to develop an action plan which sets out steps which could improve air quality in Truro.  We consulted the public and interested parties to get their views on the draft action plan, and the final version now forms part of the Clean Air for Cornwall Strategy.
