Resolution MEPC.364(79) adopts 2022 Guidelines on the method of calculation of EEDI for new ships

The International Maritime Organization has published Resolution MEPC.364(79), adopting the 2022 Guidelines on the method of calculation of the Attained Energy Efficiency Design Index (EEDI) for new ships.

This Resolution was published on January 1st, 2023.

"The IMO Marine Environment Protection Committee (MEPC),

Recalling article 38(a) of the Convention on the International Maritime Organization concerning the functions of the Marine Environment Protection Committee (the Committee) conferred upon it by international conventions for the prevention and control of marine pollution from ships,

Noting that regulation 22 (Attained Energy Efficiency Design Index (attained EEDI)) of MARPOL Annex VI, as amended, requires that the EEDI shall be calculated taking into account the guidelines developed by the Organization,  

Noting also that the Committee adopted, at its seventy-third session, 2018 Guidelines on the method of calculation of the attained Energy Efficiency Design Index (EEDI) for new ships (resolution MEPC.308(73)),

Noting further that, at its seventy-fourth and seventy-sixth sessions, it adopted, by
resolutions MEPC.322(74) and MEPC.332(76), respectively, amendments to the 2018 Guidelines on the method of calculation of the attained Energy Efficiency Design Index (EEDI) for new ships,  

Having noted, at its seventy-ninth session, the need to further amend the 2018 Guidelines on the method of calculation of the attained Energy Efficiency Design Index (EEDI) for new ships (resolution MEPC.308(73), as amended),

1. Adopts the 2022 Guidelines on the method of calculation of the attained Energy
Efficiency Design Index (EEDI) for new ships, as set out in the annex to the present resolution;

2. Invites Administrations to implement the 2022 EEDI Calculation Guidelines when developing and enacting national laws which give force to, and implement provisions set forth in regulation 22 of MARPOL Annex VI, as amended;

3. Requests the Parties to MARPOL Annex VI and other Member Governments to
bring  the amendments to the attention of shipowners, ship operators, shipbuilders, ship designers, and any other interested parties;  

4. Agrees to keep these Guidelines, as amended, under review, in light of experience gained with their implementation;

5. Agrees that these Guidelines supersede the 2018 Guidelines on the method of calculation of the attained Energy Efficiency Design Index (EEDI) for new ships (resolution MEPC.308(73), as amended by resolutions MEPC.322(74) and MEPC.332(76))."
