Negotiators from the world’s leading maritime nations agreed Friday to preserve a landmark proposal aimed at introducing the first global carbon pricing system for international shipping, but stopped short of finalizing the framework, opting instead to extend negotiations into the coming months amid lingering divisions.
Delegates meeting at the headquarters of the International Maritime Organization in London concluded a week of discussions by adjourning without a final decision, scheduling further talks in the fall ahead of a potential vote on sweeping new environmental regulations for the shipping industry. The proposed rules, collectively known as the “Net-zero Framework,” remain the central foundation for ongoing negotiations, even as countries push for revisions and alternative approaches.
The decision to continue deliberations reflects both the complexity of the proposal and the competing priorities among member states. While a broad coalition of countries supports the framework as a necessary step toward reducing emissions from one of the world’s most carbon-intensive industries, others are seeking modifications that could significantly reshape its structure.
During the session, several nations introduced alternative proposals and called for greater flexibility in the negotiation process. These countries argued that maintaining an open framework would allow for more inclusive discussions and help address economic and regional disparities. Meeting chairman Harry Conway of Liberia emphasized that all options would remain under consideration, confirming that additional proposals can still be submitted ahead of the next round of talks. The working document guiding negotiations was revised to explicitly reflect that openness.
The decision to keep the process fluid drew concern from some participants, including Australia and several other countries, which warned that prolonged debate risks delaying urgently needed action. With the shipping sector under increasing pressure to decarbonize, industry stakeholders have been seeking clearer regulatory signals to guide long-term investments in cleaner technologies.
The global shipping industry accounts for roughly 3% of total greenhouse gas emissions, a figure that has risen steadily over the past decade as international trade has expanded. Most vessels rely on heavy fuel oil, a carbon-intensive energy source that produces significant levels of carbon dioxide and other pollutants. Transitioning away from such fuels will require substantial investment and technological innovation, particularly as ships typically remain in service for decades.
At the center of the negotiations is a proposed pricing mechanism that would effectively impose a fee on greenhouse gas emissions from ships exceeding designated limits. If adopted, it would represent the first worldwide carbon levy applied to an entire industry. Revenues generated from the system would be directed into a fund managed by the IMO, intended to support the development of low-emission fuels, incentivize cleaner vessels and assist developing nations in modernizing their fleets.
The proposal also includes a marine fuel standard designed to gradually tighten emissions limits over time, encouraging the adoption of alternative energy sources. Among the options being explored, ammonia has attracted significant interest due to its lack of carbon content, though challenges remain regarding safety, infrastructure and large-scale deployment.
Despite growing momentum behind the framework, opposition persists. The United States and Saudi Arabia are among the countries that have voiced strong resistance to the idea of a global carbon fee, citing concerns over economic impacts and regulatory overreach. Their stance contributed to the collapse of a previous effort to finalize the agreement last year, when a planned vote was postponed following disagreements and geopolitical tensions.
That earlier setback underscored the difficulty of achieving consensus among nations with divergent economic interests and varying levels of dependence on maritime trade. The current extension of negotiations suggests that while progress has been made, significant hurdles remain before a final agreement can be reached.
IMO Secretary-General Arsenio Dominguez struck a cautiously optimistic tone at the close of the meeting, telling delegates that discussions had returned to a constructive path while urging continued cooperation and trust-building among member states.
Climate advocates welcomed the survival of the framework but stressed that delays could undermine its effectiveness. Em Fenton of Opportunity Green described the outcome as a sign of continued support but warned against allowing the process to drift into prolonged negotiations without resolution.
Industry representatives have also emphasized the need for clarity. The International Chamber of Shipping, which represents the majority of the global merchant fleet, has been a vocal supporter of establishing a predictable regulatory environment, arguing that clear rules are essential for accelerating the transition to cleaner fuels and technologies.
The stakes for the negotiations are high. The IMO has set a target for the shipping sector to achieve net-zero greenhouse gas emissions by around 2050, a goal that will require coordinated global action and early investment decisions. With vessels often operating for 20 to 30 years, choices made in the near term will have long-lasting implications for the industry’s environmental footprint.
As talks resume later this year, negotiators will face the challenge of balancing ambition with consensus, as they work toward a framework that can both drive meaningful emissions reductions and secure the broad international support needed for implementation.
