The Carbon Intensity Indicator (CII) is within a formal review, which is due to complete by 1st January 2026. During this period, the International Maritime Organization (IMO) has invited Interested Member States and international organisations to collect data and submit information and proposals for CII system improvements. ICS wishes to engage constructively with this process, and therefore invites ship owners and ship managers to submit data via the below forms, which are for the 2023 reporting period. Updated versions for 2024 will be available via this web page in due course.
In case of any queries on the ICS CII Data Collection System, please contact [email protected]
We thank you for your cooperation on this matter.
ICS CII data collection form – For the 2023 reporting period – Statutory data
The data required to complete this form is very similar to the DCS and SEEMP part III data, which ship owners and managers are already submitting annually. Due to confidentiality restrictions, ICS is not able to recover this data from IMO, and therefore we request shipowners and managers to upload their data via the below form. Please only upload aggregate data to our system after validation and confirmation of your CII rating by your flag administration or Recognised Organisation (RO), which we anticipate will occur around mid-2024.

ICS CII data collection form – For the 2023 reporting period – Additional data
In July 2023 IMO agreed to add additional data fields to the fuel oil data collection system (DCS). These will enable:
– Greater granularity of fuel consumption recording;
– Recording of transport work, shore power and innovative technologies.
ICS anticipate this recording requirement is likely to come into force in late 2025, and hence the first year for mandatory collection of the additional data items will be 2026. Nevertheless, this data is of value within the current review of the CII rating system. Hence, on a voluntary basis, ICS encourages ship owners to also collect this additional data now, and supply unvalidated aggregate data to ICS.
If it has not been possible in 2023 to collect a full year’s data, please provide a part year’s data and state the period over which the data has been collected.
To access this form, please click below.
It is unlikely that ships will already have a system in place that facilitates the continuous recording of this additional data. Therefore, a spreadsheet is also provided to enable ships to record this data voluntarily on a continuous voyage-by-voyage basis. Unvalidated aggregate data should then be transferred from the spreadsheet to the ICS digital form at the end of each calendar year.
