Cleaner, greener, safer - our transport vision for Portsmouth 

The council performs an annual review and assessment of pollution in Portsmouth  to meet our statutory obligations, according to the Department for Environment Food and Rural Affairs (DEFRA) Local Air Quality Management Technical Guidance. To achieve this, we monitor air quality with the help of continuous monitoring stations at key locations across the city which provide us with real-time air quality monitoring data.

In Portsmouth, the main pollutants which may impact on human health are principally the products of combustion from road  traffic - mainly nitrogen dioxide. There are currently five Air Quality Management Areas (AQMAs) predicted to exceed the annual nitrogen dioxide National Air Quality Objective (NAQO) - their locations are represented in red on the 'AQMA Locations' map, available in the documents section below.

Every year we publish all of our results in the Annual Statement Report. The 2018 Annual Statement Report on air quality is available below, along with a summary document detailing the locations of our monitoring sites, and results. The 2019 report will be published during the summer.
