The new policy adopted by diplomats at the UN’s International Maritime Organization (IMO) on a global framework that will put a carbon price on shipping emissions is expected to generate $30–40 billion in revenues by 2030 roughly $10 billion annually.
The new policy will help the industry decarbonise and encourage the use of cleaner technologies.
The overall policy is expected to be formally adopted in October 2025, though several technical details remain unresolved.
The agreement is projected to deliver at best 10% absolute emissions reduction in the shipping sector by 2030- far short of the IMO’s own targets set in their 2023 revised strategy, which calls for at least a 20% cut by 2030, with a stretch goal of 30%.
The funds will be ringfenced for decarbonizing the maritime sector alone and not go towards climate financing for developing countries.
Starting in 2028, ships will be required either to transition to lower-carbon fuel mixes or pay for the excess emissions they generate. Vessels that continue to burn conventional fossil fuels will face a $380 per tonne fee on the most intensive portion of their emissions, and $100 per tonne on remaining emissions above a certain threshold.
The policy which was backed by 63 countries including Brazil, China, the EU, South Africa, Kenya, Senegal and Namibia, sets a global precedent.
Despite objections from petro-states like Saudi Arabia, the UAE, Russia, and Venezuela – who opposed both the substance and the procedure of the agreement – Norway’s compromise proposal, as the Chair of the IMO, passed in the final vote.
Countries that voted in favour include the EU, China, India, Japan, Korea, South Africa, Singapore, Norway, Kenya,
Namibia and Senegal.
While the petro-states including Saudi Arabia, UAE, Oman, Algeria and Morocco voted against.
*25 abstentions: including Pacific Island states (such as Tuvalu, Kiribati, and Fiji), Seychelles, Egypt, Ghana, Liberia, Madagascar, and Uganda
The US delegation was not present at the time of the vote and stuck to its principle of not engaging in negotiations, after circulating a text encouraging delegations to walk out from negotiations as revealed earlier on Wednesday, 9th April.
Tuvalu, speaking on behalf of Pacific nations, voiced disappointment in the plenary, raising concerns about the lack of transparency in the process, exclusion of vulnerable nations from negotiations, and raised the point that the new plan will fail to incentivise the use of cleaner fuels.
A group of 60+ countries led by the Pacific had pushed for the revenue to go towards broader climate finance use beyond the shipping industry.
The carbon pricing mechanism, based on emissions intensity, will initially allow the use of fossil liquefied natural gas (LNG). However, the regulation will progressively penalize the use of gas by the shipping industry.
Reaction quotes
Minister Antony Derjacques of the Seychelles said: “The developing countries with the greatest need came here and offered a solution. How can the other major economies ask us to take a weak deal home to our people, who are suffering as a result of the climate crisis? And how can they take it back to their constituents?”
Maria Ogbugo, Senior Associate, African Future Policies Hub, said: “In the end, the best possible outcome was achieved. The shipping industry has taken the lead in showing other hard-to-abate sectors that climate action is possible. African delegations must be commended, including Kenya,
Namibia, Senegal, South Africa, and others who rose to the occasion and supported the compromise. Now that the IMO has agreed on measures that would apply on a global level, it is key that the various regional emissions schemes start seriously considering pulling back on their unilateral measures to avoid multiplicity of schemes piling up layer after layer of costs on African consumers.”
Faten Aggad, Executive Director, African Futures Policies Hub, said:
“Reaching consensus on decarbonisation measures was bound to be difficult. But what we clearly saw is a consensus outcome that was supported by many nations including African states like Kenya, Senegal, Namibia, and South Africa. What we have now is a measure that still puts a price on the shipping sector’s emissions, which is an important starting point on which more ambition could be further built, without creating shocks on economically vulnerable countries.”
Eldine Glees, Maritime Policy Advisor at the Micronesian Centre for Sustainable Transport, said: “A universal carbon levy represents a rare opportunity to transform climate risks into sustainable development investment. Several African delegations demonstrated exceptional leadership in the technical negotiations by connecting the levy directly to critical priorities of food security, climate resilience, and equitable revenue distribution. Maintaining this united approach will be essential as implementation discussions begin.”
Laurence Tubiana, CEO at the European Climate Foundation, and Architect of the Paris Agreement, said:“The global carbon pricing scheme agreed today in the IMO is a step forward as it recognises the responsibility of polluters to contribute to climate damages.
“But it is not sufficient. In particular, the lack of a shipping levy is a missed opportunity. We know there is significant public support for levies on polluting, undertaxed industries and the super-rich.
“The world needs more international cooperation, not less, and coalitions of the willing will be more important than ever. Together, progressive partners can still achieve vital breakthroughs for climate and development finance.”
Hon. Minister Ralph Regenvanu, Minister of Climate Change Adaptation, Meteorology, Geo-Hazards, Environment, Energy, and Disaster Management of Vanuatu, said: “Let us be clear about who has abandoned 1.5°C. Saudi Arabia, the US and fossil fuel allies pushed down the numbers to an untenable level and blocked progress at every turn. These countries – and others – failed to support a set of measures that would have gotten the shipping industry onto a 1.5°C pathway. And they turned away a proposal for a reliable source of revenue for those of us in dire need of finance to help with climate impacts.”
Ambassador Albon Ishoda, Marshall Islands Special Envoy for Maritime Decarbonization, said: “We are not done. We will be back. Alongside our friends from the Caribbean, the
Pacific, Africa, Central America, and the UK. Still standing. Still steering.”
