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.
What is good, and what to watch
Strong points
- A year of certainty for a build signed nowNothing can be adopted before October 2026 and nothing can bite before March 2029 on the most likely reading. A yacht contracted this autumn will not be overtaken by a new fuel standard during her build, which is the practical worry an owner had eighteen months ago.
- The threshold leaves the yacht fleet outsideAs drafted the framework starts at 5,000 gross tonnes. It captures around 85 per cent of shipping's emissions and virtually none of the yachts afloat. For most owners this is a rule about the ships they share the sea with, not about their own boat.
- The technical work carried on regardlessThe guidelines working group met on schedule the week after the adjournment. Whatever October 2026 produces will arrive with the detail drafted, which lowers the chance of a rushed text with expensive edges in it.
- There is time to make compliance a specification, not a retrofitTank space, electrical headroom and a documented retrofit path can be bought at contract stage for very little and cost a great deal to add later. The delay is the window in which that is a cheap decision.
What to watch
- This was a delay, not a defeat57 to 49 with 21 abstentions is a narrow and contested result driven by pressure on the day, not a settled position. A dozen votes moving in October 2026 adopts the framework, and nothing in the adjournment changes the substance of the text.
- A build ordered this autumn lands inside the window anywayA 60-metre ordered in late 2026 hands over in 2029 or 2030, on or after the earliest date the rules can apply. The engineering that decides whether she complies is fixed at signature, years before the rulebook is finished. That gap belongs to the owner, not to the yard.
- IMO thresholds have historically moved downwardSuperyachtNews argues that reading 5,000 GT as a permanent exemption is a mistake, on the precedent of MARPOL's own standards tightening over time. A 2,000 GT yacht is comfortably outside today and is not guaranteed to be outside in a decade.
- The cost cannot be budgeted, only reservedNo remedial unit price has been adopted, so nobody can put a number on what missing the intensity target would cost per year. An owner can set money aside against it; he cannot yet price it, and neither can the yard quoting him.
- Charter and resale will react before the law doesYachts above 500 gross tonnes that trade internationally already meet scrutiny from port authorities, flag states and charter clients. Buyers price a known risk early, so the brokerage market is likely to start sorting hulls by how cheaply each can be brought into line well before 2029.
Practical detail
| The vote | 57 member states voted to adjourn the extraordinary session for twelve months, 49 voted against, and 21 abstained. Saudi Arabia proposed the motion. The session sat from 14 to 17 October 2025. |
|---|---|
| When it comes back | The extraordinary session of the Marine Environment Protection Committee reconvenes in October 2026. The IMO has confirmed the twelve-month adjournment; it has not published an exact date for the resumed session. |
| Who the framework covers as drafted | Ships above 5,000 gross tonnes. That threshold reaches roughly 85 per cent of maritime greenhouse gas emissions and almost none of the yacht fleet. |
| What it would actually do | Two instruments together: a greenhouse gas fuel intensity standard that tightens year by year, and a pricing and reward mechanism that charges ships which miss the target and pays those which beat it. |
| The earliest it can bite | 1 March 2029 or later on DNV's reading of the adjournment, against 1 March 2028 before it. The Global Maritime Forum sets out a path in which adoption this year gives entry into force in 2028 and effect in 2029. |
| The drafting did not stop | The intersessional working group on the reduction of greenhouse gas emissions from ships met as scheduled from 20 to 24 October 2025. October 2026 resumes a text that has kept moving, not a blank page. |
| Where your yacht sits against the line | 5,000 GT is very large indeed for a yacht: the great majority of the delivered fleet certifies far below it, and the hulls that do not are the largest in the world. Ask the yard for the certified gross tonnage and the margin left to 5,000 before you sign. |
| The three questions to put in the contract | 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. Priced answers in the specification are worth more than assurances. |
| What is NOT published | No date for the resumed session, no final guidelines text, no adopted price for a remedial unit, and no yacht-specific exemption in either direction. Any cost per tonne quoted today comes from a draft, and the draft is what October 2026 is for. |
Questions this story answers
What happened?
The IMO's Net-Zero Framework was meant to be adopted in October 2025. A vote of 57 to 49 adjourned the session for twelve months instead, and the earliest date the rules can bite moved from March 2028 to March 2029. Anyone signing a build contract this autumn is ordering a yacht into a rulebook nobody has finished writing.
What is good about it?
A year of certainty for a build signed now. Nothing can be adopted before October 2026 and nothing can bite before March 2029 on the most likely reading. A yacht contracted this autumn will not be overtaken by a new fuel standard during her build, which is the practical worry an owner had eighteen months ago.
What should an owner or buyer watch?
This was a delay, not a defeat. 57 to 49 with 21 abstentions is a narrow and contested result driven by pressure on the day, not a settled position. A dozen votes moving in October 2026 adopts the framework, and nothing in the adjournment changes the substance of the text.
