The International Maritime Organization (IMO) has kept its flagship shipping decarbonization plan on course following a tense week of negotiations in London, with member states opting to preserve the framework rather than risk another breakdown in talks.

At the close of MEPC 84, the IMO’s Net-Zero Framework (NZF) remained intact as the central basis for continued negotiations, despite sustained pressure from a coalition led by the United States to revisit key elements of the proposal. The outcome broadly aligned with expectations, reflecting both the resilience of the framework and the deep divisions that continue to shape the debate.
IMO Secretary-General Arsenio Dominguez described the talks as being “back on track,” while acknowledging that rebuilding trust among member states will be critical to reaching a final agreement later this year.
The meeting was widely viewed as a crucial political checkpoint following last year’s narrow and contentious delay of the framework, which exposed significant geopolitical fault lines. Those tensions resurfaced at MEPC 84, particularly around the issue of carbon pricing.
The United States, echoing concerns raised by Federal Maritime Commission Chairman Laura DiBella, argued that the framework could impose widespread costs across global supply chains and ultimately burden consumers. Washington pushed for broader negotiations that would reopen the framework and consider alternative approaches.
However, the anticipated collapse of the NZF did not materialize. Instead, a broad coalition—including the European Union, United Kingdom, Australia, and Canada—held firm in support of the framework’s core structure, particularly its carbon pricing mechanism, widely seen as the cornerstone of the proposal.
The divide within the IMO remains stark. While one bloc views carbon pricing as essential for driving emissions reductions and funding the energy transition, another group—including the United States, Saudi Arabia, and the UAE—has advocated for revisions ranging from removing carbon pricing entirely to weakening fuel standards that could prolong reliance on fossil fuels.
The United States framed the outcome as a partial win, with the State Department stating that its coalition had succeeded in expanding negotiations to include competing proposals. According to Washington, this opens the door to alternatives that could eliminate the carbon pricing component altogether—though other delegations maintain that the NZF remains the primary negotiating text.
Faced with the risk of deadlock, delegates chose to move forward without forcing a vote. The framework will now be refined through a series of intersessional meetings scheduled for September and November, with a potential decision expected in December.
Industry stakeholders welcomed the continuation of talks but cautioned that consensus remains elusive. The International Chamber of Shipping noted that while dialogue has been constructive, significant differences persist, warning that prolonged uncertainty could delay critical investment decisions across the sector.
Shipowners are currently weighing billions of dollars in commitments tied to alternative fuels and emerging technologies, making regulatory clarity increasingly urgent.
Reactions from delegates and observers suggest cautious optimism. Representatives from climate-vulnerable nations indicated that the framework remains viable for adoption this year, with Pacific states expressing confidence that it can advance largely unchanged to support a fair and equitable energy transition.
Environmental groups, however, struck a more urgent tone, warning that reopening negotiations risks undermining years of progress and delaying emissions cuts at a critical juncture.
Some observers also challenged the narrative that the framework lacks broad support, pointing instead to a coalition spanning Europe, Africa, Latin America, and small island states that continues to back the NZF as the most practical path forward.
Still, there are concerns that simply keeping the framework alive is not enough. Prolonged negotiations could dilute its ambition or push implementation timelines further into the future.
The debate is unfolding against a volatile global energy backdrop. Ongoing tensions in the Middle East have driven sharp swings in bunker fuel prices, reinforcing arguments from supporters that a global carbon pricing system could bring long-term stability and accelerate the transition to cleaner fuels.
Critics, however, maintain that such measures could increase costs and disrupt trade flows, underscoring the central tension that will shape the next phase of negotiations.
Beyond the climate framework, MEPC 84 delivered several concrete regulatory outcomes. The IMO approved a new Emission Control Area in the Northeast Atlantic, set to tighten limits on sulphur oxides, nitrogen oxides, and particulate emissions from 2028.
The committee also advanced a strategy aimed at eliminating plastic waste discharges from ships by 2030, progressed work on a global code for transporting plastic pellets, and adopted amendments to strengthen ballast water management and address underwater noise pollution.
Reflecting broader geopolitical concerns, the IMO also passed a resolution condemning attacks on commercial shipping in the Strait of Hormuz, highlighting the increased risk of large-scale marine pollution linked to ongoing conflict in the region.
While MEPC 84 stopped short of delivering a final agreement, it avoided a breakdown that could have derailed years of negotiations. The IMO’s Net-Zero Framework remains firmly in play, with carbon pricing still at the heart of discussions.
The coming months will determine whether the framework evolves into the shipping industry’s first global carbon pricing system—or becomes another casualty of geopolitical division.
