7. 10. Identification and evaluation of solutions for long-haul electric road freight.

   Master-uppsats, Linköpings universitet/Logistik- och kvalitetsutveckling

   Författare :Amanda Lundström; Gustav Lindén; [2023]
   Nyckelord :Electric road freight; long-haul; TCO; Tripple bottom line;

   Sammanfattning : Road freight transportation is important for the development of the global economy and, at the same time, one of the most destructive businesses when it comes to the environment and human health. As societies evolve, the need for freight transportation increases and the transport demand cannot in a sustainable way be fulfilled with the use of diesel trucks as it is done today. LÄS MER
