We have revised a previously issued ClassNK Technical Information (No. TEC-1250 dated 10 November 2021) related to the survey and Certification for EEXI required by the Amendments to ANNEX VI of MARPOL. This Technical Information supersedes the previously issued No.TEC-1250.

At the 76th session of the IMO Marine Environment Protection Committee (MEPC 76) held in June 2021, further amendments to MARPOL Annex VI were adopted (IMO Resolution MEPC.328(76)) to implement the Energy Efficiency Existing Ship Index (EEXI) as a technical approach to achieve the short-term target for improved transportation efficiency of at least 40% compared to 2008 and will enter into force on 1 November 2022.

EEXI is calculated using the same formula as EEDI and represents "the amount of CO2 emissions from a ship when the ship sail transports one ton cargo for one nautical mile".　Regardless of ship's delivered date, ships of 400 gross tonnage and above engaged in international voyages are subject to the EEXI regulations and the EEXI of each ship is to be calculated.　Ships of a specific size and above subject to the EEXI regulations need to comply with the requirement equivalent to the EEDI requirement as of 2023. Under the EEXI regulations, "Bulk carrier", "Tanker", and "Ro-ro cargo ship (vehicle carrier)" need to comply with the EEXI requirement equivalent to Phase 2 EEDI requirement, while "Containership", "General cargo ship", "LNG carrier", and "Gas carrier" comply with the EEXI requirement equivalent to Phase 3 EEDI requirement.　Therefore, a ship subject to EEDI regulations which comply with the Phase 2 or Phase 3 requirement automatically complies with the EEXI regulations.　If a ship does not meet the EEXI requirement, the ship needs to implement any countermeasures, such as engine power limitation, installation of energy saving devices, etc. to improve the EEXI.
Ships delivered before 1 January 2023 need to comply with the EEXI regulations by the first periodical survey of IAPP Certificate on or after 1 January 2023. On the other hand, ships delivered on or after 1 January 2023 need to comply with the EEXI regulations at the delivery. There are about 7,200 ships registered with ClassNK which are subject to the EEXI regulations and about 6,050 ships will need to implement any countermeasures such as engine power limitation. This is equivalent to about 84% of the total number of ships subject to EEXI regulations, which means that a large number of ships need to comply with the EEXI regulations.
