The impact on the operational profile of different ship types and solutions for future-proofing existing vessels

From 2023 onwards, all sea-going vessels of 5,000 GT and above will need to monitor and report their real CO2 emissions under a new IMO Carbon Intensity Indicator (CII) assessment programme. 

Every ship will be categorised for its carbon intensity, while owners must document how they will maintain or – if necessary – improve vessel performance. 

This paper explains the basics of CII and that a ship’s CII rank is established on an individual basis. It also evaluates the application of the CII to a typical container ship and a bulk carrier, analysing the impacts of measures to improve performance.  

It emphasises that steps to enhance CII performance must also be ship-specific and continuously monitored, so that a ranking or its planned improvement can be fully documented.
