The European Environmental Agency (EEA) publishes an Emission Inventory Guidebook whichprovides emission factors for different vehicle types. In this emission inventory, passenger cars are defined as vehicles carrying up to nine passengers, whereas light duty vehicles (LDVs) are defined as vehicles with a gross weight of up to 3500 kg. LDV emission factors of total suspended particles (TSP), PM10 and PM2.5 were 57% higher than those of passenger cars for both tyre and brake wear, but road surface wear was the same for both.
