The 2023 EU MRV and IMO DCS reporting period will soon come to an end, whilst the EU ETS regulations are coming into effect from the start of the new year. As we approach year-end, DNV summarizes some important clarifications on the EU MRV, IMO DCS and EU ETS.
IMO DCS/CII
The Carbon Intensity Indicator (CII) is a measure of how efficiently a ship can transport goods or passengers and is given in grams of CO2 emitted per cargo-carrying capacity and nautical mile, based on reported IMO DCS data. The ship is then given an annual rating ranging from A to E, where the rating thresholds will become increasingly stringent towards 2030.
For ships that achieve a D rating for three consecutive years or an E rating in a single year, a Corrective Action Plan (CAP) needs to be developed (and approved) as part of the Ship Energy Efficiency Management Plan (SEEMP) Part III, before the DCS Statement of Compliance can be issued. This functionality will be available in DNV’s SEEMP Part III tool from 1 January 2024:
Upon receiving the uploaded DCS data in early 2024, DNV will inform its customers via email for ships having a CII E rating (where urgent action is needed). Furthermore, our customers will receive a notification of the ship rating during the submission process.
Required and attained CII calculation after change of DWT/GT during 2023
As outlined in MEPC.348(78), permanent alterations to a vessel’s deadweight (DWT) and/or gross tonnage (GT) can be implemented as a measure within SEEMP Part III or as a CAP to enhance the ship’s operational carbon intensity performance. For vessels that underwent changes in DWT and/or GT after 1 January 2023, a new methodology for calculating attained and required CII will apply:
a. For changes listed in the SEEMP Part III or the CAP:
The required CII is calculated based on the original DWT/GT*. For the year of the conversion, the attained CII is calculated and verified based on the average DWT or GT value weighted on distance travelled before and after conversion. For subsequent years, the attained CII is based on the new DWT/GT.
b. For changes not listed in the SEEMP Part III or the CAP:
For the year of the conversion, the required CII and attained CII are calculated and verified based on the average DWT or GT value weighted on distance travelled before and after conversion. For subsequent years, the required CII and attained CII are based on the new DWT/GT.
