Report of ISWG GHG 8 - 24 to 28 May 2021
A lot of progress was made on the technical details of the EEXI and CII guidelines during the ISWG G. But the spirit of consensus did not allow the thorniest subjects to be resolved : reduction factors in Guidelines CII G3, correction factors and voyage exclusions in particular.
A lot of progress was made on the technical details of the EEXI and CII guidelines during the ISWG GHG 8 meeting held this week, thanks to the excellent chairmanship of Mr. Sveinung Oftedal (Norway).
But the spirit of consensus maintained by the latter did not allow the thorniest subjects to be resolved (Guidelines CII G3 in particular).
Thus, the discussion on the reduction trajectory by 2030 gave rise to bitter debates and fairly deep divisions have emerged between Member States that do not share the same approaches to climate issues.
Anticipating the serious consequences that the absence of a proposal for the coming decisive MEPC 76, a compromise was nonetheless agreed, thanks to the willingness of some delegations, even unhappy with the proposed reduction rates.
Likewise, the issue of Correction factors and Travel exclusions turned out to be too delicate to be dealt within the space of a few days and was therefore referred to post-MEPC 76 work, within a new Correspondence Group.
Guidelines supporting the EEXI framework
ISWG GHG 8 finalized a new version of the draft Guidelines on the method of calculation of the attained energy efficiency existing ship index (EEXI), for adoption at MEPC 76 (item 1 and annex 1 of this report) :
ISWG GHG 8 finalized a new version of the draft 2021 guidelines on survey and certification of the energy efficiency existing ship index (EEXI), for adoption at MEPC 76 (item 2 and annex 2 to this report).
ISWG GHG 8 finalized a new version of the Draft Guidelines on the Shaft/Engine Power Limitation System to comply with the EEXI requirements and use of a power reserve, for adoption at MEPC 76 (item 3 and annex 3 to this report).
Guidelines supporting the CII framework
ISWG GHG 8 finalized a new version of Draft Guidelines on operational carbon intensity indicators and the calculation methods (CII guidelines, G1) for adoption at MEPC 76 (item 4 and annex 4 to this report).
ISWG GHG 8 finalized the Draft Guidelines on the reference lines for use with operational carbon intensity indicators (CII Reference line guidelines, G2), with a view of adoption at MEPC 76 (item 5 and annex 5 to this report).
Despite an obvious dissatisfaction from many representatives of Member States, ISWG GHG 8 finalized the draft guidelines on the reference lines (G3) with a view to adoption by MEPC 76 (item 6 and annex 6 to this report).
ISWG GHG 8 has finalized the draft Guidelines on the operational carbon intensity rating of ships (CII Rating Guidelines-G4), with a view to adoption by MEPC 76 (item 7 and annex 7 to this report)
ISWG GHG has decided to keep the rating boundaries set by the CG, recalling that the reference lines were already size-dependent but recognized that some adjustments could still be done on this matter.
ISWG GHG agreed that all proposals addressing inequities between ship types (i.e. correction factors, refined reference lines, etc.) should be considered holistically within the CG to be established by MEPC 76.
Regarding the update of the 2016 Guidelines for the development of a Ship Energy Efficiency Management Plan (SEEMP) (resolution MEPC.282(70)),
ISWG GHG has decided to keep the rating boundaries set by the CG, recalling that the reference lines were already size-dependent but recognized that some adjustments could still be done on this matter.
ISWG GHG agreed that all proposals addressing inequities between ship types (i.e. correction factors, refined reference lines, etc.) should be considered holistically within the CG to be established by MEPC 76.
ISWG GHG not agreed to a proposal for the SEEMP guidelines to include an option for compliance at company/fleet level.
Due to time constraints, the ISWG could not consider following items :
Owing to the high amount of work still to be carried-out, a new Correspondence group on carbon intensity reduction should be established by MEPC 76 with some heavy tasks to carry out:
A new ISWG GHG 9 should be held also 18-22 October 2021, before MEPC 77.
