The CII is a rating system for ships that the International Maritime Organization (IMO) developed. This will be a mandatory measure under MARPOL Annex VI, which comes into force in 2023.

The plan must include a description of how the vessel will operate and maintain its fuel efficiency throughout the year in line with its overall objective of reducing CO2 emissions and meeting its CO2 reduction commitments. SEEMP Part III documentation is in addition to SEEMP Part I and SEEMP Part II.
