Nowadays, real-world emissions and consumption behaviour of Light Duty (LDV) and Heavy Duty (HDV) vehicles are key factors in achieving greenhouse gas (GHG) targets. With the introduction of EURO VI in 2013 there were already low emission levels and real fuel consumption of new HDV vehicles. Furthermore, the available public literature regarding fuel consumption of European HDV vehicles is not very extensive. Hence, the development of an experimental activity related to HDVs real consumption measurement and the subsequent data analysis can be considered in this field. To this end, the fuel consumption data of four rear-loader garbage Diesel trucks, managed by a multiservice company in the Southern Italy, were collected during real use. Vehicles in pairs have different technical characteristics (i.e. engine capacity and maximum load capacity of the garbage).

The LCA (Life Cycle Assessment) methodology is nowadays considered fundamental for the estimation and analysis of the economic and social impacts coming from the CO2 (Carbon Dioxide) footprint. It is a methodology for evaluating the “environmental footprint” of the product, “from cradle to grave” and it is carried out by quantifying the impacts deriving from both the use of resources and emissions into the environment. The aim of this study is to contribute to environmental assessment in the context of the sustainability of vehicular transport in urban areas. For this reason, through a comparative analysis of the LCA it is possible to evaluate the CO2 emissions deriving from cars during real use and relating to the entire life of the vehicles. Three comparisons were made considering pairs made up of an electric vehicle and an internal combustion vehicle of the same segment and category: small city cars, mid-size and SUV.
