Winchester City Council Air Quality Supplementary Planning Document

Closed 12 Apr 2021

Opened 15 Feb 2021


Under its environmental duties set down with the Environment Act 1995, Winchester City Council declared an Air Quality Management Area back in 2003.  Although there has been a steady improvement, air quality remains an issue of concern in the city.  In 2017 the Council adopted a new Air Quality Action plan, which set out a number of actions which collectively seek to reduce nitrogen dioxide levels within the city centre, in order to protect public health.  One such measure is to adopt an Air Quality Supplementary Planning Document (AQ SPD) which, through the planning regime, aims to ensure that developments with the defined AQ SPD area, deliver on a set of clear air quality impact standards and in certain locations reduce exposure to pre-existing poor air quality.  As a secondary benefit, the proposed AQ SPD also aims to support the Council’s carbon reduction objectives.  

This public consultation seeks the views of developers, planning agents, lobby groups and the public on the proposed AQ SPD, which will be used to fully inform the council’s decision on adoption going forward. 

In participating, all consultees should read the proposed AQ SPD in full before responding to the consultation, which is expected to take 15 – 20 minutes.

Thank you for your valued participation.
