ISWG APEE 1/2/10: Illustrating the overlap of the CII with the mid-term measures, and proposing Z-factors in alignment with the 2023 IMO GHG Strategy targets

ISWG APEE 1/2/10: Illustrating the overlap of the CII with the mid-term measures, and proposing Z-factors in alignment with the 2023 IMO GHG Strategy targets

This document presents evidence for the high potential of energy efficiency to contribute to the achievement of the 2023 IMO GHG Strategy, and includes new calculations that show this would require a supply-based carbon intensity reduction factor of 55% by 2030, compared to 2008, equivalent to a reduction factor of 41% by 2030 compared to 2019. The analysis also shows that it would be possible to quite easily go beyond the 2023 IMO GHG Strategy targets and align shipping emission reductions with a genuine 1.5°C Paris Agreement trajectory.

As this week’s meeting of the International Maritime Organization’s Marine Environment Protection Committee (IMO, MEPC 84, April 27-May 1) closes today, the Clean Shipping Coalition welcomed support from the majority of member states for the IMO’s Net-Zero Framework (NZF) despite pressure from US, Saudi Arabia, UAE, Panama, Liberia, and other petro-states, but called out the threat of further delays to adoption, which is now scheduled for early December.

Ahead of next week’s meeting of the International Maritime Organization’s Marine Environment Protection Committee (IMO, MEPC 84, April 27-May 1), the Clean Shipping Coalition welcomed progress made during this week’s intersessional meeting and called on member states to “hold the line against those looking to once again disrupt and delay” on the IMO’s Net-Zero Framework (NZF).

Member states must use these coming days to build out key guidelines, such as those for incentives for first movers and how to measure the emissions from different fuels, to allow for adoption of the Net Zero Framework later this year.
