There is no shortage of fixes to improve a ship’s Carbon Intensity Indicator ratings.

New propulsion systems with alternative fuels, more efficient motors, anti-fouling hull coatings, onboard electric systems, heating and cooling systems, flow meters, rotor sails — the list goes on.

But the most important first step might be better measuring of ships’ actual efficiency and emissions, rather than the basic long-lived exercises of adding up fuel loading figures and sending noon reports.
