With increasing global focus on sustainability, new regulations on emissions and environmental compliance are set to impact the maritime industry. Recognising the importance of regulatory compliance, Britannia P&I, in collaboration with HFW , has developed comprehensive guidance documents covering FuelEU, EU ETS, CII and EEXI regulations . These resources provide shipowners and charterers with clear regulatory overviews and practical compliance guidance. We encourage all members to stay ahead of these changes, and we will continue to provide timely updates and expert insights. These fuel regulations articles were written in consultation with the leading global law firm HFW. Whilst care has been taken to ensure the accuracy of this information at the time of publication, the information is intended as guidance only. It should not be considered as legal advice. Read the full guidance. CII (Carbon Intensity Indicator) Regulations: CII and EEXI (Energy Efficiency Existing Ships Index) have global effect and are imposed by MARPOL in accordance with Marine Environment Protection Committee (MEPC) 328(76). What? An ongoing operational tool used to measure the carbon intensity generated by the operational performance / commercial activities of individual ships (e.g. CO 2 emissions per deadweight ton miles in accordance with the Annual Efficiency Ratio (AER) Metric). When? A ship is required to develop, and keep updated, an enhanced Ship Energy Efficiency Management Plan (SEEMP). Ships collect and report fuel consumption data during annual reporting period. By 31 March in the subsequent verification period, the consumption data is verified. After 30 April in the verification period, the verified consumption data is compared to the required baseline carbon intensity for the ship and an annual CII Rating of “A” to “E” will be allocated to ships. The benchmark for carbon intensity (required CII) reduces by 2% each year until 2026, after which the IMO
