Local Authorities are required to review and assess air quality and where there are air quality issues, work towards achieving the objectives through development and implementation of an Action Plan. Defra and the Devolved Administrations have produced technical and policy guidance for local air quality management as well as practice guidance notes. The UK LAQM webpages provide additional information on all aspects of LAQM including reporting, tools for assessment, action planning, helpdesk details and more.
This group provides details on some of the tools available to assist with Local Air Quality Management and allows users to review them, adding to the user experience. Tools for LAQM can be considered to assist with three distinct phases of the process:
Tool descriptions contain references to these three categories where possible to give the user an idea of when they may be most helpful.
Users of the tools should also consider impacts of measures and developments on carbon emissions and noise and should seek win- win policies wherever possible. These tools are also widely used for assessment of air quality for the purpose of Development Control. Tools to assess impacts on carbon are available through this website.

This is a simple screening tool for road traffic emissions. The tool was designed to be used for air quality assessments of road schemes multi-modal studies and by local authorities carrying out their
The tool is an Excel spreadsheet which reproduces the graphs for biomass burning published in LAQM.TG(09). The use of biomass to generate energy has potentially significant benefits for the reduction
The EXEMPT Model is in two parts; both parts are an evolution of the previous TRAMAQ3 EXEMPT Model 4. The models can be used as simple tools for assessing the effects of certain types of developments
The Travelfootprint tool assesses the impacts of the main modes of passenger travel in the UK. The analysis includes an assessment of the environmental impacts associated with the fuel cycle (primary
This tool is part of a suite of tools developed for Local Air Quality assessments. It estimates the annual mean nitrogen dioxide concentrations at one distance from a road using measurements made
The Local Air Quality Management (LAQM) technical guidance (TG09) provides factors for predicting pollutant concentrations in future years. Please note that the NO2 factors have since been updated and
This spreadsheet tool (also known as the Supplementary Assistance spreadsheet for stack height calculation) estimates the chimney height required for sulphur dioxide emissions from small boilers. A report
The tool provides a step by step template to easily calculate the estimated monetary value (Net Present Value) of the air quality impacts of a tested policy. The tool uses the methodology as set out in
Many Local Authorities are now carrying out diffusion tube co-location studies. A spreadsheet has been developed to assist diffusion tube users in calculating the precision and accuracy of their results
A database of bias adjustment factors determined from Local Authority co-location studies throughout the UK has been collated by the Local Air Quality Management Helpdesk. Using orthogonal regression
MS Excel spreadsheets which reproduce the graphs published in LAQM.TG(09).
This website provides the National Trip End Model (NTEM) forecasts and the TEMPRO software. These are used for transport planning purposes. The forecasts include population employment households by
This website provides Annual Average Daily Flow (AADF) and traffic data for every junction-to-junction link on the 'A' road and motorway network in Great Britain. It enables the user to search view
The EFT toolkit allows the user to calculate vehicle emissions for multiple road links based on vehicle fleet composition traffic speeds and road type. EFT Version 5.1 allows the calculations of vehicle
This calculator allows NO2 concentrations to be derived from NOx wherever NOx is predicted by modelling emissions from roads. The calculator can also be used to calculate the road component of NOx
Background maps are provided to assist UK Local Authorities with their Review and Assessment of air quality where local monitoring data is not available. Background concentrations are provided for
The NO2 background sector tool is compatible with the 2010 based background maps and allows users to remove NOx sectors from the NOx background maps and recalculate background NO2 concentrations.
The tool was developed to assist local authorities in the calculation of CO2 emissions from their estates and operations in accordance with the reporting requirements of National Indicator 185. The
