The main aim of this research effort is to assess the impact of the different circulating vehicle fleets on PM10 pollution, comparing the results from the ten most populated metropolitan cities in Italy. Circulating diesel vehicles have been categorized in different groups depending on the vehicle type (car or Light Commercial Vehicle - LCV) and European emission standard. The annual mileage and the total PM10 emission for each category has been determined based on several data sources.

Although in many developed countries the green transition towards sustainable mobility is going faster and faster towards low or zero emission vehicles, road traffic is so far one of the key PM10 pollution source in urban areas. This research compares and analyses correlations between PM10 pollution trends in urban areas and the following parameters: vehicles fleet, rain precipitations and diesel fuel sales. The city of Rome has been selected as pilot area, analysing data gathered by its PM10 monitoring network between 2006 and 2017.
