year, using the data collected in accordance with regulation 27 of this Annex,
taking into account the guidelines to be developed by the Organization.
2 Within three months after the end of each calendar year, the ship shall report to
its Administration, or any organization duly authorized by it, the attained annual
operational CII via electronic communication and using a standardized format to be
developed by the Organization.
3 Notwithstanding 1 and 2 of this regulation, in the event of any transfer of a ship
addressed in regulations 27.4, 27.5 or 27.6 completed after 1 January 2023, a ship
shall, after the end of the calendar year in which the transfer takes place,
calculate and report the attained annual operational CII for the full 12-month
period from 1 January to 31 December in the calendar year during which the transfer
took place, in accordance with regulations 28.1 and 28.2, for verification in
accordance with regulation 6.6 of this Annex, taking into account guidelines to be
developed by the Organization. Nothing in this regulation relieves any ship of its
reporting obligations under regulation 27 or this regulation of this Annex.
Required annual operational carbon intensity indicator (required annual
operational CII)
4 For each ship of 5,000 gross tonnage and above which falls into one or more of the
categories in regulations 2.2.5, 2.2.7, 2.2.9, 2.2.11, 2.2.14 to 2.2.16, 2.2.22, and
2.2.26 to 2.2.29 of this Annex, the required annual operational CII shall be
determined as follows:
Required annual operational CII = (1− ) · CIIR
where,
5 The annual reduction factor Zfootnote and the reference value CIIR shall be the
values defined taking into account the guidelines to be developed by the
Organization.
Operational carbon intensity rating
6 The attained annual operational CII shall be documented and verified against
the required annual operational CII to determine operational carbon intensity rating
A, B, C, D or E, indicating a major superior, minor superior, moderate, minor
inferior, or inferior performance level, either by the Administration or by any
organization duly authorized by it, taking into account the guidelines developed by
the Organization. The middle point of rating level C shall be the value equivalent
to the required annual operational CII set out in paragraph 4 of this regulation.
Corrective actions and incentives
7 A ship rated as D for three consecutive years or rated as E shall develop a plan of
corrective actions to achieve the required annual operational CII.
8 The SEEMP shall be reviewed to include the plan of corrective actions accordingly,
taking into account the guidelines to be developed by the Organization. The revised
SEEMP shall be submitted to the Administration or any organization duly authorized
by it for verification, preferably together with, but in no case later than 1 month
after reporting the attained annual operational CII in accordance with paragraph 2
of this regulation.
9 A ship rated as D for three consecutive years or rated as E shall duly undertake
the planned corrective actions in accordance with the revised SEEMP.
10 Administrations, port authorities and other stakeholders as appropriate, are
encouraged to provide incentives to ships rated as A or B.
Review
11 A review shall be completed by 1 January 2026 by the Organization to assess:
-
.1 the effectiveness of this regulation in reducing the carbon intensity of
international shipping;
-
.2 the need for reinforced corrective actions or other means of remedy,
including possible additional EEXI requirements;
-
.3 the need for enhancement of the enforcement mechanism;
-
.4 the need for enhancement of the data collection system; and
-
.5 the revision of the Z factor and CIIR values.
If based on the review the Parties decide to adopt amendments to this regulation,
such amendments shall be adopted and brought into force in accordance with the
provisions of article 16 of the present Convention.
Regulation 29
Promotion of technical cooperation and transfer of technology relating to the
improvement of energy efficiency of shipsfootnote
1 Administrations shall, in cooperation with the Organization and other international
bodies, promote and provide support, as appropriate, directly or through the
Organization to States that request technical assistance, especially developing
States.
2 The Administration of a Party shall cooperate actively with other Parties, subject
to its national laws, regulations and policies, to promote the development and
transfer of technology and exchange of information to States which request technical
assistance, particularly developing States, in respect of the implementation of
measures to fulfil the requirements of chapter 4 of this Annex, in particular
regulations 19.4 to 19.6.
