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.

London Healthy Waterways Boat Dweller Survey 2025

Rust-Ryan Research and Training Consultancy is conducting a study to explore how air pollution, fuel usage, and energy options affect boat dwellers across London. The research aims to gather insights into boaters' awareness of air pollution and its health impacts, their access to energy sources, challenges in switching from solid fuels, and their attitudes toward sustainability and the climate emergency.

We invite all London boat dwellers, including continuous cruisers and those on permanent moorings, to participate by completing a brief online survey or taking part in face-to-face interviews at key mooring locations.

For more information, please check out the Preamble about boat dweller survey for waterways agencies and organisations.

Change of NRMM LEZ standards

The Non-Road Mobile Machinery (NRMM) Low Emission Zone (LEZ) policy is key to the mayor's plan to improve London's air quality. It aims to reduce pollution for millions of Londoners near construction sites.

From 1 January 2025 the Central Activities Zone (CAZ), Opportunity Areas and Greater London zones will no longer have different emission standards. The standards will be EU Stage IV across Greater London.

Details are on the Non-Road Mobile Machinery (NRMM) website.
