1. 1. Enabling a sustainable transition of a waterborne transport system : By identifying essential aspects and actors

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Julia Apelgren; Sara Kronvall; [2023]
   Nyckelord :Sustainable transition; Waterborne transport system; Transport system; Public transport system; Fossil free fuels; System theory; Passenger ferry; Commuter ferry; Electric ferry; Hållbar omställning; Vattenburet transport system; Transport system; Kollektivtrafik; Fossila bränslen; Systemteori; Passagerarfärja; Pendelbåt; Elektrisk färja;

   Sammanfattning : In light of the emerging consequences of climate change, there is a need for a sustainable transition of the marine sector, including waterborne transport systems, towards implementation of fossil free fuels and technologies. The thesis limits its scope to solely include passenger ferries that are suitable for calm waters and often operates on shorter distances, which are often incorporated in a public transport system and/or archipelago traffic.
