As members are aware, CII is a rating system developed by the International Maritime Organization (IMO) to measure the energy efficiency of ships above 5,000 gross tonnage and trading internationally and came into effect on 1 January 2023. It is currently in an experience-building phase, with a formal review running in parallel until 1 January 2026.

Following the IMO’s invitation during the Marine Environment Protection Meeting (MEPC80) in July for interested Member States and international organisations to collect data and submit information and proposals, ICS has developed a system that enables shipowners and managers to submit data, including fuel consumption, transport work, and the trial metrics. Such information will enable a clearer understanding of how fairly and effectively the CII system is functioning and provide the necessary input to the IMO for system improvement.

ICS invites shipowners and relevant stakeholders to utilise the ICS Data Collection System to contribute to a fair and successful CII rating system in the future.

The ICS data collection system can be accessed here.

We request all members participate and, therefore, invite ship owners and ship managers to submit data via the forms on this website for the 2023 reporting period. Updated versions for 2024 will be available via this web page in due course.
