What are we doing to lower air pollution

Clean Air Zone

In November 2021, Portsmouth City Council launched a Clean Air Zone following central government identifying Portsmouth as one of 60 local authorities where air pollution was in excess of legal limits. A ministerial directive was issued to the Council in March 2020 to introduce a Clean Air Zone in the south-west of the city, with £3.4 million funding1 offered to install and promote the Zone and build volumes of new electric vehicle charging stations.

Additionally, £3.2 million was awarded for the Clean Air Fund to assist in upgrading non-compliant vehicles. In the first three months of the CAZ2, funding supported the upgrade of 66 HGVs, 162 buses and coaches, and 119 taxis and private hire vehicles including 26 which are wheelchair accessible.

Engine idling

A city-wide multimedia marketing campaign launched in December 2022 to educate residents that one minute of engine idling equals 150 balloons worth of harmful emissions3 released into the air with the campaign: When you stop, engine stops.

To support the campaign, Portsmouth City Council launched an engine idling reporting tool.
