CII Calculator

The Marine Environmental Protection Committee, adopted, at its 76th session, by resolution MEPC.328(76), the 2021 Revised MARPOL Annex VI, which will enter into force on 1 November 2022, and contains amendments concerning the mandatory goal-based technical and operational measures to reduce carbon intensity of international shipping. In that direction, through Regulation 28.1 of MARPOL Annex VI, the ships to which the regulation applies, are required to calculate the attained annual operational Carbon Intensity Index (CII), taking into account the IMO Guidelines.

In order to provide guidance for uniform and effective implementation of regulations and to provide sufficient lead time for the industry to prepare, the Committee adopted by MEPC.336(76), the 2021 Guidelines on the operational carbon intensity indicators and calculation methods.

A Dromon approved enhanced Ship Energy Efficiency Management Plan (SEEMP) needs to be kept onboard from January 01, 2023. The enhanced SEEMP part III will require companies to specify the methodology the ship will use to calculate the attained carbon intensity indicator (CII).

DBS has developed a CII Calculator, taking into account the 2022 Guidelines according to all the latest Resolutions of Marine Environmental Protection Committee Meeting 78.

We highly recommend reading through the following guidelines before using the calculator: IMO Resolutions & Guidelines
