It is well known that air pollution from traffic sources increases when traffic is congested and also when there are more motor vehicles travelling along a given stretch of road. One indication of this can be seen in the reduction of air pollution concentrations measured in 2020 during lockdown periods of the COVID-19 pandemic (see Air Quality Expert Group report).
HLRA remains committed to scrutinising air pollution data to act in the best interests of local residents.
In spring 2022, it is expected that a Clean Air Zone (CAZ) will be introduced in Greater Manchester. It is hoped this will result in reduced heavy traffic and cleaner-running HGVs. (The charges would not affect private cars.)
