Shipping's fuel rule slips to October, and 2028 becomes 2029
A session that adjourned instead of adopting
The International Maritime Organization called an extraordinary session of its Marine Environment Protection Committee for 14 to 17 October 2025 with one item on the agenda: adopting the draft amendments to MARPOL Annex VI that carry the IMO Net-Zero Framework. The committee did not adopt them. A majority of 57 member states voted to adjourn the session for twelve months against 49 who wanted it to continue, and the IMO has confirmed the extraordinary session will reconvene in October 2026.
The framework is two instruments bolted together. The first is a global standard for the greenhouse gas intensity of the fuel a ship burns, tightening year by year. The second is a pricing and reward mechanism that charges ships which miss the intensity target and pays those which beat it. The delay stopped the vote, not the drafting: the guidelines working group carried on regardless.
The only date that matters moved by a year
The original plan put entry into force at 1 March 2028 at the earliest. DNV's reading of the adjournment is that the date now moves to 1 March 2029 or later, and how much later depends on what October 2026 produces. The Global Maritime Forum's guide sets out a plausible path in which it is adopted this year, enters into force in 2028 and takes effect in 2029. Both readings sit a full year further out than the industry was planning around eighteen months ago.
For an owner the arithmetic is uncomfortable rather than academic. A 60-metre ordered in the autumn of 2026 is a 2029 or 2030 delivery, which puts her handover on or after the earliest date the rules can apply. The engineering that decides whether she complies is fixed at contract signature: fuel type, tankage, exhaust treatment, and the space left for a retrofit nobody has specified yet. That gap between the decision and the rule belongs to the owner, not the yard.
Where the 5,000 gross tonne line falls
As drafted the framework applies to ships above 5,000 gross tonnes, a threshold that reaches roughly 85 per cent of maritime emissions while catching almost none of the yacht fleet. Nearly every yacht afloat sits below it, and the handful that do not are the largest hulls in the world, whose owners already run compliance as a department. On the face of it the yacht market is a spectator here.
SuperyachtNews argues that treating the threshold as a permanent exemption is a mistake, on the grounds that IMO thresholds have historically scaled downward, as MARPOL's own standards did. Yachts above 500 gross tonnes that trade internationally or charter face scrutiny from port authorities, flag states and charter clients long before any rule reaches them. The pressure lands on charter appeal, resale values and port access first.
The flags on the transom have already agreed a list
The Red Ensign Group held its 37th annual conference in Bermuda from 30 June to 2 July 2026, with more than 70 delegates from its 16 members across the United Kingdom, the Crown Dependencies and the Overseas Territories. It was opened by the Honourable Owen Darrell, Bermuda's Minister for Tourism, Transport, Culture and Sport. The group's own account names the priorities its members agreed on: register growth, long-term planning, practical cooperation, consistent standards across administrations, maritime security and resilience, sanctions coordination, and environmental protection and decarbonisation.
The last item on that list is the one to read twice. The group takes in Cayman, the Isle of Man, Gibraltar, Jersey, Guernsey and Bermuda, the registries whose certificates sit in the paperwork of a great many large yachts. They have put decarbonisation and consistent standards on an agreed agenda three months before the IMO reconvenes. James Way, Guernsey's Harbour Master, told the conference that membership gives the island access to network expertise.
The questions to settle before October
There is nothing to comply with yet, which is what makes the next three months useful. The questions worth putting to a yard now are narrow and answerable. What gross tonnage will this yacht certify at, how much margin sits between that number and 5,000, and what would a retrofit cost if the threshold moved down. A contract can carry those answers as a priced specification rather than an assumption.
The second question belongs to the broker. If a fuel-intensity standard and a price on emissions do arrive in 2029, the brokerage market will begin sorting hulls by how cheaply each can be brought into line, and it will start well before the rule is in force, because buyers price a known risk early. A yacht with tank space, electrical headroom and a documented retrofit path is a different asset from one without, and the difference will show up in the ask.
