This paper presents a review of the different International Maritime Organization (IMO) initiatives to improve the ship energy efficiency of new and existing ships, which is considered one of the essential tasks to reduce Greenhouse Gas (GHG) in the maritime industry. First, the IMO effort and initiatives and the different indices suggested by the IMO are presented till the last version of the Marine Environment Protection Committee (MEPC), showing the effect of different technologies on reducing the level of indices and the suggested improvement of the terms of indices in the next years. Second, the short- and long-term strategies suggested by the IMO are presented, showing that the effect of indices will be noticed in the short term, while the new fuels will show a significant improvement in the long term. Finally, several examples of cooperation between the different organizations are presented, showing that transferring knowledge and experience will significantly impact the maritime industry and thus lead to the concept of green ships in the near future. This paper shows that the combination of different solutions, the cooperation between stakeholders and the sharing of the data and information are important to achieve the required goal.

Environmental protection is one of the most challenging tasks facing mankind. Reducing CO2 emissions in the global economy, including maritime transport, is being pursued in various ways, one of them being the design work leading to the construction and operation of unmanned ships. Unmanned vessels operating on longer routes will still have internal combustion propulsion. However, they will not have the superstructure and the various systems and equipment necessary for the crew. This will result in an unmanned vessel having less weight, less displacement and, therefore, less size, resistance and propulsion power than a manned vessel for the same transport capacity. Consequently, the unmanned vessel will emit less CO2. This paper presents a novel method for predicting fuel consumption and CO2 emissions for unmanned container ships. The method uses regression relationships of geometric and operational parameters for manned container ships developed for this purpose to determine such relationships for unmanned ships. On this basis, it is shown what the level of CO2 reduction will be compared to manned container ships.
