Welcome to the LAQM Support Website
The Local Air Quality Management (LAQM) Support Website is provided by Defra and the Devolved Administrations. It contains a variety of support functions for local authorities and practitioners of LAQM.
Specifically, it is designed to support local authorities in carrying out their duties under the Environment Act 1995, the Environment (Northern Ireland) Order 2002, and subsequent regulations.
This diffusion tube data processing tool has been developed to assist local authorities in processing their NO2 diffusion tube monitoring data. It allows annual mean NO2 concentration results to be calculated from NO2 diffusion tube raw monthly data including bias factor adjustment, annualisation and distance correction calculations.
In order to assist local authorities in undertaking their Review and Assessment duties, a generic report template is available, which should be used when submitting LAQM Reports.
In order to assist local authorities in undertaking their Air Quality Action Plan duties, a generic Report Template is available, which should be used when submitting AQAPs

The LAQM Process
The LAQM process places an obligation on all local authorities to regularly review and assess air quality in their areas, and to determine whether or not the air quality objectives are likely to be achieved.
Local authorities and LAQM practitioners can use this site to:
- Access templates, good practice and technical/policy guidance for LAQM reporting.
- View and download tools to assist with the assessment of air quality.
- View information related to Air Quality Management Areas (AQMA).
- Access the LAQM Portal.
The Devolved Administrations and Greater London Authority also host supplementary air quality information on separate pages:
- The Scottish Government.
- Llywodraeth Cymru Welsh Government.
- Northern Ireland Department of Agriculture, Environment and Rural Affairs.
- Greater London Authority.
Further air quality information can also be found on the UK-AIR website. In addition, the Air Quality Hub is a free, online knowledge sharing resource for those working in the field of local air quality management.
