The shipping industry has long charted its decarbonization journey around the International Maritime Organization’s (IMO) Net Zero Framework. However, last Friday, it was dimmed. At least for a year. The IMO’s decision to postpone adoption of the framework signals not just a bureaucratic delay, but a worrying pause at a time when the clock to 2030 is ticking loudly.
According to the Climate Action in Shipping: Progress Towards Shipping’s 2030 Breakthrough report, produced by the Global Maritime Forum with the UCL Energy Institute and the UN Climate Change High Level Champions, progress across the sector’s five levers: technology, demand, finance, policy, and civil society: is uneven. Technology is moving fast: methanol- and ammonia-fueled ships are transitioning from prototypes to pilot fleets.
“We have seen excellent progress over the past year, with methanol and ammonia having now shifted from potential solutions towards initial scale and proof of concept,” said Jesse Fahnestock, Head of Research and Analysis at the Global Maritime Forum.
But without regulatory certainty, these early wins risk losing direction. The IMO’s delay leaves investors, shipowners, and fuel producers in limbo. A year’s pause in global policy alignment can mean years of delay in project financing, vessel orders, and fuel infrastructure, precisely when the sector needs to be pushed further.
The report warns that despite growing electrolyser capacity, fuel production remains far below what’s required for the 2030 target: at least 5% of shipping’s energy use from scalable zero-emission fuels. “Technology for ammonia and methanol vessels is advancing. However, despite growing electrolyser capacity, fuel output is still far below the 2030 target.” Current production pipelines could supply barely a quarter of that. As Fahnestock cautions, “technology readiness is not enough by itself.”
This moment calls for leadership beyond the IMO. Governments, financiers, and major cargo owners must use this pause to double down on commitments, by setting regional carbon-pricing schemes, signing long-term green fuel offtake deals, and supporting first-mover projects that prove viability.
Shipping’s decarbonization story has always been a race between engineering and economics. The technology is here; the rules are not. A delayed framework risks turning 2030’s “climate breakthrough” into another missed horizon.
In the wake of the IMO’s delay, industry frustration has deepened over what many see as politics overtaking pragmatism. Dr. Martin Kröger, CEO of the German Shipowners’ Association (VDR), warned that the failure of the recent IMO Marine Environment Protection Committee (MEPC) session “is not a failure of ambition by the shipping industry — it is the result of politics overpowering pragmatism.” He pointed out that the European Union’s regional measures risk undermining the very global system they claim to support, while countries such as the United States and Saudi Arabia continue to block progress in defense of short-term petro-economic interests. “Shipping sits in the middle — a global industry trapped between regional overreach and geopolitical rivalry,” Kröger said.
If governments remain divided, he argued, the industry itself must lead by rebuilding consensus with international partners and advocating for “one global framework, one fair and simple path forward — centred on practical transition and not political point-scoring.” A straightforward global fuel levy, he suggested, could provide such a mechanism. “Regional systems and national energy politics cannot decarbonise global trade,” Kröger added. “Only the IMO can — if governments let it.”
The decision’s postponement has drawn a more measured response from research and innovation leaders. In a statement, the Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping emphasized that the delay “does not mean the Framework has failed.” The organization noted that the IMO’s 2023 Greenhouse Gas (GHG) Strategy, committing the sector to net-zero emissions by 2050, “remains in place, an impressive achievement then, and even more so today.” Still, the Center acknowledged that without the Net Zero Framework, the industry temporarily loses the clarity it needs to guide global investments and incentives for decarbonization. It urged IMO Member States to use the coming year to rebuild consensus and finalize “a global framework that can deliver certainty for long-term planning and investment, incentives to accelerate innovation, and fairness through a just and equitable transition for developing states.” Despite the setback, the Center reaffirmed its commitment to collaborate with partners to turn ambition into action. “While the decision is postponed,” it stressed, “the urgency remains.”
The IMO may have postponed its course, but the industry cannot afford to wait. The tide for clean shipping is rising. What’s missing is the wind of policy to push it forward.
