From 2023, the CII thresholds and reduction requirements will take effect for all cargo, RoPax, and cruise vessels above 5,000 GT and trading internationally, as referred to in regulation 28 of MARPOL Annex VI. The CII ratings and limits are named as A to E. Going forwards these limits will be reduced annually.
Ships that fall into the category from D or E have a high exposure to finance, charter, and regulatory risks and penalties. They will require a plan that will outline how the CII rating will be improved to a rating of C, or higher, as part of its Ship Energy Efficiency Management Plan (SEEMP).
Marine Digital has created an innovative web dashboard indicating the fleet CII, with its historical dynamics and a future forecast. The initial CII assessment is based on historical data and the ships' digital twins.
