Air quality

Our aim is to improve air quality in the borough for the health and benefit of our residents, businesses and visitors.

This is done by:

monitoring the environment,
controlling pollution emissions,
giving advice,
and where possible, taking enforcement action.

Information within this site has been divided into four sections:

'Air pollution and complaints' provides detailed information for residents who are having problems related to air pollution. There are contact details and links to register complaints and report problems.
'Air quality projects and campaigns' provides information on what we are monitoring and why, what we are doing to help improve local air quality, as well as what you can do to get involved.
'Advanced Information on Air Quality' contains information for professionals seeking to support planning applications or review our monitoring data.
Air quality and planning contains information about managing development work to avoid a negative impact on people and the environment.
