Ahead of a big green meeting at the International Maritime Organization next week, John Maggs from the Clean Shipping Coalition writes on how getting a global fuel standard and levy over the line will set us up for the future.
International shipping makes an outsized and growing contribution to the climate crisis. Ships also regularly kill whales and generate underwater noise that compromises the ability of whales and other marine life to forage and reproduce. By going more slowly, ships could slash their climate emissions and reduce both underwater noise and the risk of whale strikes—but as the Clean Shipping Coalition’s John Maggs explains, this shift won’t happen without ambitious regulation.
The International Maritime Organization has been asked to enact a carbon levy of $150 per ton of emissions from large freight and passenger ships. The IMO’s 175 member nations have until next year to vote.

This document builds on document ISWG-GHG 17/3 (CSC) to complement the extensive literature review on the well-to-tank (WtT) GHG intensity of liquified natural gas (LNG) imports in the European Union, including information and literature to determine a WtT value for a global default emission factor.
This document presents information on the current literature about tank-to-wake (TtW) nitrous oxide (N2O) emissions from ammonia dual-fuel engines. Recent studies indicate significant variability in N₂O emissions across engine types, operating conditions, and testing methodologies. This document compiles emission data and findings from the most up-to-date laboratory tests and modeling efforts. The summarized results are presented in g N2O/g NH3 units, without normalization of scenario parameters across studies. The co-sponsors propose that the Committee agree to forward these results to the GESAMP-LCA Working Group to be used as part of their mandate to improve the robustness of GHG accounting for ammonia-fueled ships.
As delegates meet at the International Maritime Organization in London this week, Seas At Risk has released the following infographic to push for a strong Carbon Intensity Indicator (CII), a global greenhouse gas fuel standard and an ambitious levy.
