EMIT 3.4 Released


A new version of EMIT is now available. EMIT is a simple, fast and comprehensive tool for compiling, editing and analysing emissions inventories. EMIT is invaluable in many situations, for example when carrying out emission calculations across large urban areas when dispersion modelling with ADMS-Urban, and when predicting the impact of Low Emission Zones on emissions of toxic pollutants and greenhouse gases.

The new features in EMIT 3.4 include:

  • Updated road traffic emission factors and fleet data based on the UK National Atmospheric Emissions Inventory 2014 and Defra's Emission Factor Toolkit version 6.0.
  • Source apportionment: quantifying the contributions from particular road vehicles, such as diesel cars, to emissions and concentrations (when used with ADMS-Urban). The apportionment is fully user-defined; for example emissions can be apportioned by EURO class or vehicle size.
  • Greatly improved speed: large calculations now take minutes rather than hours.

For more information about the new features please see the What's New in EMIT 3.4? guide. EMIT users with current support contracts will shortly receive the new version free of charge. Further information and prices can be found on our website.
