A key Ecoship deliverable is an estimated 40% C02 reduction in comparison with a cruise ship with conventional propulsion built before 2000; and an estimated 30% reduction compared to a good current design.

These results will be achieved through the combination of the propulsion efficiency, hull forms, accommodation efficiency, hull air bubbles and renewable technologies, as well as by route, speed and management measures.

This calculation has been done according to the International Maritime Organization’s 2004 guidelines on the method of calculation of the attained energy efficiency design index for new ships (EEDI). It is intended to define the C02 produced per transported unit or, in the case of passenger vessels, by gross tonnage. The result may vary slightly depending on operational conditions.
