The EEDI addresses the former type of measure by requiring a minimum energyefficiency level for new ships; by stimulating continued technical development of all the components influencing the fuel efficiency of a ship; and by separating the technical and design-based measures from the operational and commercial ones. It is already being used to enable a comparison to be size that could have undertaken the same transport work (i.e. moved the same cargo).

The amendments to MARPOL Annex VI Regulations for the prevention of air pollution from ships, entering into force on 1 January 2013, add a new chapter 4 to Annex VI on Regulations on energy efficiency for ships to make mandatory the Energy Efficiency Design Index (EEDI), for new ships, and the Ship Energy Efficiency Management Plan (SEEMP) for all ships.

RULES FOR GREEN SHIPS aim to advocate the development and application of green technologies, promote the structural optimization and upgrading of shipbuilding, related manufacturing and shipping industries, promote the use by shipping companies of cost-effective technologies and management measures to new and existing ships so as to increase the green grade in the operation of their fleets and, with safety as the precondition, achieve the goals of low consumption, low emissions, low pollution and comfortable working environment for their ships.

CCS has developed the technical file of guidelines on the method of calculation of the attained energy efficiency design index (EEDI) for new ships, guidelines on survey and certification.

A ship, which has, upon its request, undergone plan approval and surveys by CCS and its compliance with the requirements of these Rules is there by confirmed by a comprehensive assessment of the green elements in the three aspects of environmental protection, energy efficiency and working environment, may be assigned one of the following Green Ship class notations as appropriate: Green Ship I/II/III

CCS offers a range of assessment and classification of green ship.
