The aim of this study is to examine the proposals that they are submitted by the relevant authorities on the pricing of carbon emissions from maritime transport.The goal of zeroing emissions from maritime transport, which it has the highest share in international transportation, constitutes one of the most important environmental movements of today. In this context, by the relevant authorities have been proposed alternative financing approaches in order to raise capital for advanced engineering studies and technological developments that are needed to zero ship-sourced carbon emissions.The IMO, which is the maritime authority, has proposed an international carbon tax approach for pricing carbon emissions in the financial system, on the other hand, The EU Commission has planned to include to EU ETS the emissions from ships associated with the European continent. At the IMO meetings, the participants also proposed a new financing model on an international scale, to be called IMRF and to be financed by fuel tax. In the investigations, it has been concluded that international financing models are more effective approaches for the implementation of zero emission technologies.
