The IMO said the new measures will require all ships to
calculate their Energy Efficiency Existing Ship Index (EEXI) following
technical means to improve consumption and establish annual operational carbon
intensity indicator (CII) and a subsequent rating.
Carbon intensity links the GHG emissions to the amount of
cargo carried over distance travelled.
Ships will get a rating of their energy efficiency (A, B, C,
D, E – where A is the best). Administrations, port authorities and other
stakeholders as appropriate, are encouraged to provide incentives to ships
rated as A or B also sending out a strong signal to the market and financial
sector.
A ship rated D for three consecutive years, or E, is
required to submit a corrective action plan, to show how the required index (C
or above) would be achieved.
IMO Secretary-General Kitack Lim said the adoption of the
new measures would build on IMO’s previously adopted mandatory energy
efficiency measures, to lead shipping on the right path towards
decarbonisation.
“The path to decarbonization is a long, but also a common
path in which we need to consider and respect each other’s views. We have made
a considerable amount of progress since the start of our journey,” Lim said.
“Your progress will continue to provide the benefit of
experience to be able to make ambitious, and evidence-based decisions for phase
3 of the implementation of the operational measure which will be further
strengthened and developed taking into account the review of the short-term
measure and the latest climate science.”
The amendments to MARPOL Annex VI (adopted in a consolidated
revised Annex VI) are expected to enter into force on 1 November 2022, with the
requirements for EEXI and CII certification coming into effect from 1 January
2023.
This means that the first annual reporting will be completed
in 2023, with the first rating given in 2024.
A review clause requires the IMO to review the effectiveness
of the implementation of the CII and EEXI requirements, by 1 January 2026 at
the latest, and, if necessary, develop and adopt further amendments.
