The Environment Act 1995 (Part IV) requires that all local authorities carry out periodic reviews of the current and likely future air quality in their area. These reviews follow Government guidance that set health-based air quality objectives for a number of key pollutants and target dates for their achievement. The main pollutants of relevance currently for East Suffolk are nitrogen dioxide (NO2 ) and particulate matter (PM2.5 and PM10 ).
The main sources of the pollutants in the East Suffolk district are emissions from road traffic, industrial processes, biomass combustion, construction sites and significant local commercial operations such as the Port of Felixstowe.
