In the present study, I have evaluated the carbon footprint of road freight transport of different technologies to understand what the benefits and further development of each of them can be. I carried out the study according to the international GHG Protocol standard and the principles expressed by ISO 14067 following the APOS model and evaluating the impact in terms of CO2 eq / ton * kilometer. The environmental impact for transport with a traditional Euro VI vehicle of one ton of goods per kilometer turns out to be 0.218 kg of CO2 eq/tkm while for Euro IV vehicles this value increases by 3%. On the other hand, if we consider refrigerated vehicles these impacts increase by 12%. Electric vehicles produce 0.189 kg of CO2 eq/tkm but could be reduced by 16% if energy from renewable sources is used. Hydrogen-powered vehicles emit 0.169 kg CO2 eq/tkm if the hydrogen comes from electrolysis and 0.329 kg CO2 eq/tkm if the hydrogen comes from natural gas. Finally, I stressed the importance of using a vehicle throughout its useful life, in fact if you decide to decommission an electric vehicle after five years, it will have impacted more than a conventional Euro VI vehicle used for six years.
Nel presente studio ho valuta l’impronta carbonica del trasporto merci su strada di diverse tecnologie in modo da capire quale possono essere i vantaggi e gli ulteriori sviluppi di ognuna di queste. Ho svolto lo studio secondo lo standard internazionale del GHG Protocol e i principi espressi dalla ISO 14067 seguendo il modello APOS e valutando l’impatto in termini di CO2 e / tonnellata * chilometro. L’impatto ambientale per il trasporto con un veicolo tradizionale Euro VI di una tonnellata di merce per un chilometro, risulta essere pari a 0,218 kg di CO2 e/tkm mentre per i veicoli Euro IV questo valore aumenta del 3%. Se invece consideriamo veicoli refrigerati questi impatti aumentano del 12%. I veicoli elettrici producono 0,189 kg di CO2 ed/tkm ma potrebbero essere ridotte del 16% se viene utilizzata energia proveniente da fonti rinnovabili. I veicoli alimentati ad idrogeno emettono 0,169 kg di CO2 eq/tkm se l’idrogeno proviene da elettrolisi e 0,329 kg di CO2 eq/tkm se l’idrogeno proviene dal gas naturale. Infine, ho sottolineato l’importanza di utilizzare un veicolo per tutta la sua vita utile, infatti se si decide di dismettere un veicolo elettrico dopo cinque anni, questo avrà impattato più di un veicolo tradizionale euro VI utilizzato per sei anni.

Abstract
In the present study, I have evaluated the carbon footprint of road freight transport of different technologies to understand what the benefits and further development of each of them can be. I carried out the study according to the international GHG Protocol standard and the principles expressed by ISO 14067 following the APOS model and evaluating the impact in terms of CO2 eq / ton * kilometer. The environmental impact for transport with a traditional Euro VI vehicle of one ton of goods per kilometer turns out to be 0.218 kg of CO2 eq/tkm while for Euro IV vehicles this value increases by 3%. On the other hand, if we consider refrigerated vehicles these impacts increase by 12%. Electric vehicles produce 0.189 kg of CO2 eq/tkm but could be reduced by 16% if energy from renewable sources is used. Hydrogen-powered vehicles emit 0.169 kg CO2 eq/tkm if the hydrogen comes from electrolysis and 0.329 kg CO2 eq/tkm if the hydrogen comes from natural gas. Finally, I stressed the importance of using a vehicle throughout its useful life, in fact if you decide to decommission an electric vehicle after five years, it will have impacted more than a conventional Euro VI vehicle used for six years.File | Dimensione | Formato | |
