A Decision Support GIS Framework for Establishing Zero-Emission Maritime Networks: The Case of the Greek Coastal Shipping Network

Abstract Sustainability of maritime operations is a topic widely considered in recent years, as the shipping industry attempts to limit its environmental impact and meet decarbonization goals set by International Maritime Organization (IMO). As alternative fuels newer ship technologies are gaining interest, shift more environmentally friendly fleets quickly becoming reality. In this context, potential areas for such shifts need be determined, expedite efforts provide passengers with sustainable way travel. Greece an insular country, complex coastal network connecting mainland islands being paramount importance their economic growth. Recognizing accessibility needs, paper examines whether Greek (GCSN) can restructured, introducing zero-emission sub-networks operated electric ferries. The aim propose methodological framework spatial analysis evaluation networks, implementation exploratory data (ESDA) methods determination local indicators association (LISA) help geographic information systems (GIS). proposed provides insight on where restructuring possible, introduction new transshipment port hubs from which ferries could operate, thus determining electrification additionally high renewable resource potential. Final conclusions indicate that certain parts GCSN while results GHG emissions reduced calculated.
