ABSTRACT
The article presents the regulations of the International Maritime Organization aimed at reducing carbon dioxide emissions from international shipping. One of the main objectives is to search the alternative to fossil fuels. The main problem is the lack of indication of the target fuel for shipping. The current changes, forced by international regulations, are made by the decisions of shipowners who themselves are looking for an alternative fuel that will enable them to continue their activities. Attempts have been made to use fuels considered as transient, which will be used in the perspective of about 10 years. However, this is too short a time compared to the life of the ship (20-30 years). This will force another change in the type of fuel used on ships still in operation, which will result in additional costs associated with the adaptation of the ship’s power plant fuel systems to a different type of fuel. The article evaluates the changes that currently taking place. Scenarios of the most likely directions of changes in a perspective of 2050 have been indicated.
