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 emissions for NOx, PM10, PM2.5, Carbon Dioxide and Hydrocarbons. It incorporates updated vehicle exhaust emission factors, and includes consideration of brake and tyre wear and road abrasion for PM10 and PM2.5.
This tool can be used to justify the process i.e. help assess emissions or air quality impacts.http://laqm.defra.gov.uk/review-and-assessment/tools/emissions.html
