The global fallout of the closure of the Strait of Hormuz may create the impression that the world cannot function without fossil fuels. Nothing could be further from the truth. Every single industry can and must decarbonise.

For global shipping, this process would be relatively easy because technological solutions exist and a single United Nations agency can set legally binding rules for all ships. The first steps have already been made.

In 2025, member states of the International Maritime Organization (IMO) agreed on a policy mechanism to cut shipping emissions: the Net-Zero Framework (NZF). But they opted to postpone a decision on formal adoption of this landmark agreement.

This delay is emblematic of obstructive tactics used by countries opposing climate action.

The IMO Framework – the world’s first global carbon price on any international polluter – took years of compromises and watering-down. As it stands, it is the lowest possible bar Pacific Island states like the one I represent can accept. We cannot give in another inch.

While I join the First Conference on Transitioning Away from Fossil Fuels in Santa Marta, Colombia, next week, delegates will gather again at the IMO in London to decide whether to uphold their unanimous commitment to phase out fossil fuels in a just and equitable way.

The delegates of Vanuatu who travel to London have a mandate to push for the adoption of the NZF this year.

Should anyone reopen the framework to water it down, our position is clear: We will revert to our original Pacific demand for a universal levy on emissions of $150 per tonne of carbon dioxide.

Last year my country abstained from the vote on the NZF agreement. We reached that decision because the mechanism is not nearly ambitious enough. Even so, it is a starting point we can work with.

But since then, the tide has shifted dramatically.

After the delay in adoption, a small group of countries is now suggesting further weakening the ambition in the framework to meet the demands of particularly influential states whose current policy positions are not aligned with climate ambition. This strategy is problematic as reducing our collective actions to align with those that want no climate action at all is incompatible with our people’s continued survival.

The world’s poorest countries, and the planet, simply cannot afford anything less than what is already on the table.

The framework, as it is, gives the world and the industry some chance of meeting the climate obligations that IMO countries committed to in 2023, namely reaching net-zero emissions by 2050 in a just and equitable way.

The NZF introduces penalty fees – eg emission pricing for noncompliance with the regulation. This provides the regulation with a “stick” to ensure ships comply or else they must pay.

The penalties also represent revenues, up to $10bn to $12bn a year, to both incentivise industry transition and enable a fair transition for all. This fund is a lifeline for developing – and especially least developed – states to be able to afford clean maritime energy upgrades and compensate for the rising trade costs because of this transition.

Some claim that revenues raised by the NZF will blow out transport costs. This is preposterous.

The penalties charged through this framework come down to less than $1.50 per year for every living human being – although the biggest polluters should pay this cost. If the richest 10 percent of the world’s population foots this bill, it adds up to less than $15 per person. That’s a few coffees a year, which the world’s richest can easily spare.

Losing both financial penalties for noncompliance and financial support for countries like mine in the name of a political compromise with rich oil-producing states is a bad deal. Not just for all climate-vulnerable states but also for the industry that demands and deserves clarity.

If anything, we need more action and more ambition in the framework.

For years, Pacific states have pushed for the IMO regulation to be in the form of a universal levy on emissions, by pricing all emissions. We managed to get the majority of IMO member states on board, including the European Union, South Korea and Japan, as well as important Global South states, such as Panama and Liberia. However, the US has been very effective in exerting its influence in this area, which is resulting in shifts to some positions to the detriment of us all.

Our position was always backed by the best available scientific evidence.

A levy on all shipping emissions is the best way to send an unambiguous signal to the industry: Invest in the future now! The revenues, up to 10 times more than those from the NZF, serve as both a bigger stick for polluters and a bigger carrot for first movers and cash-poor countries.

This is not a handout: Hitting net zero by 2050 is not possible if our countries cannot invest in clean ships.

The bridge we have built in the form of the NZF through years of compromise and evidence is still standing. Let us cross it together by adopting it as agreed without any further dilution.

Pacific states stand ready to fight for what science and justice demand, and we call on our partners to stand with us.
