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
Provides an independent estimate of the UK’s GHG emissions for reporting to the UNFCCC and is updated annually. Information from a wide range of sources is collected and analysed from national
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 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
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
A database containing emission factors used in the UK emissions inventory as well as factors speficially designed for Local inventories. In addition 1*1km emission maps for the UK are available
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
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 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
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
MS Excel spreadsheets which reproduce the graphs published in LAQM.TG(09).
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
These conversion factors are produced by the UK Government to help companies calculate greenhouse gas emissions from a range of activities including energy use and transport activities. These
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
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
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
