Today the International Chamber of Shipping (ICS), association International shipowner representing more than 80% of the fleet world merchant ship, has started its own collection system of data on the Carbon Intensity Indicator (CII), the efficiency index energy of a ship which is expressed in grams of CO2 emitted by ship's carrying capacity and nautical miles traveled by the naval unit. The system based on the CII index entered into force last January and was introduced by the International Maritime Organization (IMO), the agency of the United Nations for the safety of maritime transport and the prevention of pollution caused by ships. The system provides for the assignment to each ship of gross tonnage greater than 5,000 tons of a rating on a scale A (best energy performance) to E conferred on the basis of the CII index on the energy performance of ships in 2023. A ship that will receive a D rating for three years consecutive or an E rating for one year must submit a plan of corrective measures to achieve a C rating or higher.

The ICS has specified that the decision to create its own Data collection system was taken as a result the invitation made by the IMO at its July meeting on own Marine Environment Protection Committee (MEPC) so that the Member States concerned and the organisations concerned collect data and submit information, and Proposals.

The data collection system set up by the ICS has the objective - explained the association - to support the IMO in the its formal review of the CII rating system which should be implemented by 1 January 2026. 'All'International Chamber of Shipping - specified Chris Waddington, director ICS technician and CII data collection system manager of the association - we intend to engage constructively in the current phase of defining the revision of the CII for ensure that the system is fit for purpose and effective. The ICS data collection system offers shipowners and managers of ships the opportunity to provide data that in the future will improve the rating system. We encourage shipowners to use the system to offer first-hand guidance on this that works well and on the possible challenges within the system. This data will be shared with the IMO and will keep the Dialogue on how best to achieve our goals for the 2030, 2040 and 2050 net-zero carbon emissions'.
