The International Maritime Organization postpones adoption of its crucial Net-Zero Framework by 12 months amid geopolitical disagreements, delaying global shipping decarbonisation efforts until 2028 and intensifying regulatory uncertainty.
On October 17, 2025, the International Maritime Organization (IMO) chose to postpone by 12 months the much-anticipated adoption of the IMO Net-Zero Framework, a critical regulatory instrument aimed at decarbonising the international shipping industry. The vote delay, decided during an extraordinary session of the Marine Environment Protection Committee (MEPC) held in London, reflects lingering political disagreements and economic concerns among member states, especially outspoken opposition from the United States and several other countries. The rescheduled formal vote is set for October 2026, pushing the earliest potential implementation of the Framework to March 1, 2028, pending the required acceptance period.
The IMO Net-Zero Framework, preliminarily agreed in April 2025 but not yet legally adopted, is designed to drive maritime greenhouse gas (GHG) emissions down to net-zero by around 2050 in line with the IMO’s 2023 Strategy on the Reduction of GHG Emissions from Ships. It primarily seeks to incentivise the transition away from unabated fossil fuels towards renewable and low-carbon alternatives by imposing mandatory limits on the carbon intensity of energy used aboard ships, coupled with a global carbon pricing mechanism. This market-based approach would charge ships based on their emissions intensity, with penalties aimed at encouraging sustainable fuel adoption and funding low-carbon infrastructure.
The Framework’s delay introduces a significant period of regulatory uncertainty for key stakeholders including shipowners, shipbuilders, fuel producers, and financial investors. Many leading shipping companies have already made commitments to fleet decarbonisation, investing in vessels powered by LNG, ammonia, methanol, and various biofuels and e-fuels. These actors need clear, harmonised international rules to underpin further investments, secure long-term fuel contracts, and mitigate substantial retrofit costs associated with alternative fuel compatibility. The postponement also complicates infrastructure planning and financing for emerging fuel supply chains, particularly amid a potentially fragmented regulatory landscape.
One of the central objections contributing to the delay lies in concerns about the Framework’s governance structure. Some member states, including the United States and oil-producing countries like Saudi Arabia and the United Arab Emirates, opposed the delegation of significant discretionary authority to the IMO Secretariat to define further regulatory details post-adoption, fearing insufficient state oversight and potential regulatory expansion without proper controls. The United States government, as declared in a high-profile joint statement by top cabinet officials, rejected the Framework outright due to the perceived economic burden and inflationary pressures it might impose on shipping, commodity prices, and consumers.
In contrast, the European Union and its member states have staunchly supported the Framework as a pivotal step towards greening international shipping. Following the postponement, the EU published its updated Sustainable Transport Investment Plan, underscoring continued commitment to maritime decarbonisation through existing mechanisms such as the EU Emissions Trading System (ETS) and the FuelEU Maritime Regulation, which already apply to about half of the GHG emissions from EU-related voyages. The EU has indicated it will continue enforcing these regulations while boosting financial incentives for renewable fuel production, aiming to reduce dependency on fossil fuels regardless of the IMO’s timetable.
The European Sea Ports Organisation (ESPO) voiced concern that the delay risks stalling the sector’s climate ambitions and prolonging regulatory fragmentation, which could complicate compliance and create an uneven competitive playing field. This fragmentation is a shared concern among shipping stakeholders, as unilateral or regional decarbonisation efforts, without a consensus global framework, generate compliance complexity and political risks that may deter broad investment in low-carbon technologies.
During the extended interim period before the next MEPC session in October 2026, the IMO has indicated that work will continue through its Intersessional Working Group to refine the implementing guidelines crucial for the Framework’s execution. These efforts aim to address outstanding political and technical concerns, potentially reshaping the Framework to foster broader international consensus. The next formal meeting of the MEPC in April 2026 will also serve as an essential milestone to gauge progress in negotiations and alignment among member states.
Industry experts underscore that despite the regulatory delay, the drive toward maritime decarbonisation remains inexorable as global pressures for sustainable shipping intensify. They advise shipping companies, financiers, and fuel producers to use this period strategically: modelling fuel consumption scenarios, adjusting contracts in anticipation of future rules, enhancing emissions monitoring systems, and preparing for more stringent carbon pricing regimes. Early movers embracing low-carbon technologies and robust environmental, social, and governance (ESG) frameworks are likely to gain competitive advantages and improved reputational standing in a sector increasingly scrutinised for its environmental impact.
In summary, the postponement of the IMO Net-Zero Framework reflects a complex geopolitical and economic balancing act amid divergent national interests and concerns over global competitiveness. While the delay creates short-term uncertainty, it also opens a critical window for further diplomatic engagement, technical refinement, and broader stakeholder alignment. The outcome of the upcoming MEPC sessions next year will be pivotal in determining whether the industry can achieve a unified, effective global regulatory approach to maritime decarbonisation or if fragmentation and inconsistency will persist, challenging the sector’s ability to meet urgent climate commitments.

- https://www.imo.org/en/mediacentre/pressbriefings/pages/imo-net-zero-shipping-talks-to-resume-in-2026.aspx – On October 17, 2025, the International Maritime Organization (IMO) announced the postponement of the Net-Zero Framework adoption for one year. The Marine Environment Protection Committee (MEPC) adjourned the extraordinary session, with plans to reconvene in 12 months. During this interim, member states will continue working towards consensus on the framework. The Intersessional Working Group on the Reduction of Greenhouse Gas Emissions from Ships is scheduled to meet from October 20 to 24, 2025, to continue developing implementation guidelines for the Net-Zero Framework. The framework aims to establish international regulations to reduce greenhouse gas emissions from ships, aligning with IMO’s 2023 Strategy for Reduction of GHG Emissions from Ships. It includes two key elements: a global fuel standard and a global GHG emissions pricing mechanism. The delay provides additional time for member states to address concerns and refine the framework before its formal adoption. The IMO emphasizes the importance of continued collaboration among member states to achieve consensus on the Net-Zero Framework, which is considered a significant step towards decarbonizing the maritime industry.
- https://www.reuters.com/legal/legalindustry/what-delay-imos-net-zero-framework-means-maritime-decarbonization–pracin-2025-11-06/ – The International Maritime Organization (IMO) has postponed by one year the adoption of its anticipated Net-Zero Framework, a global regulatory initiative aimed at curbing greenhouse gas emissions in the shipping sector. The proposed framework combines a fuel-intensity standard and a market-based mechanism requiring vessels over 5,000 gross tons to meet emissions targets or pay carbon fees. Revenues, expected to reach $11–12 billion annually, would fund low-carbon infrastructure and support developing nations. The delay places the maritime industry in regulatory uncertainty as companies continue to pursue voluntary decarbonization goals. It jeopardizes investment in alternative fuels like ammonia, methanol, and hydrogen, potentially causing project slowdowns. Furthermore, the absence of a global standard may lead to fragmented regional regulations, increasing compliance complexity for international shippers. Stakeholders are encouraged to use this period to prepare strategically: modeling fuel use, updating contracts, enhancing emissions monitoring, and refining ESG disclosures. Legal and financial teams should also prepare for future scenarios with possibly stricter carbon pricing. Despite the regulatory pause, sector-wide decarbonization remains inevitable, and early adopters of low-carbon technologies and governance upgrades may secure competitive and reputational advantages. The IMO is expected to revisit the framework in late 2026.

This decision was announced in a joint statement by several cabinet members from the Trump Administration—Secretary of State Marco Rubio, Commerce Secretary Howard Lutnick, Energy Secretary Chris Wright, and Transportation Secretary Sean Duffy. The statement emphasized the administration’s unwillingness to support any initiative that would impose increased costs on American citizens, energy producers, shipping companies, consumers, or tourists. The IMO member nations are scheduled to deliberate on adopting the framework in October.
- https://maritimes.gr/en/press-release-press-release-imo-espo-regrets-postponement-of-the-net-zero-framework-for-shipping-postponement-should-not-lead-to-cancellation-of-ambition/ – The European Sea Ports Organisation (ESPO) has expressed serious concern over the International Maritime Organisation’s (IMO) decision to postpone the adoption of the Net-Zero Framework (NZF) by one year. The delay, decided during last week’s Marine Environment Protection Committee (MEPC) meeting in London, risks creating a standstill in global climate ambition and lowering the pace of progress in maritime decarbonisation. The NZF was expected to establish a global regulatory foundation for reducing greenhouse gas emissions from shipping, including a fuel standard and a pricing mechanism. ESPO considers this postponement a missed opportunity to accelerate the sector’s transition to clean fuels and fears it will further prolong the fragmentation and unlevel playing field stemming from regional regulations. This decision is particularly disappointing given the strong calls from across the shipping sector for a unified global approach.
- https://www.europarl.europa.eu/doceo/document/P-10-2025-004296_EN.html – On 17 October 2025, the International Maritime Organisation (IMO) postponed the adoption of the international net zero emissions framework for maritime transport by one year, highlighting a complex scenario marked by geopolitical tensions. This delay creates uncertainty as to the coherence between European regional measures – such as the Emissions Trading System (maritime ETS) and FuelEU Maritime – and future international IMO provisions. The maritime sector has expressed concerns about the possibility of a double regulatory burden arising from the possible co-existence of both systems. In view of the above: 1. The Commission had indicated that it would review European regional measures to bring them into line with IMO decisions. Following this postponement, what plan and strategy does the Commission envisage for this transitional year? 2. If a comprehensive market measure does not enter into force, how does the Commission see the maritime ETS and the FuelEU Maritime regulation evolving in the absence of a global framework? 3. What instruments does the Commission envisage to preserve the competitiveness of the European maritime sector vis-à-vis third countries?
- https://www.velaw.com/insights/imo-postpones-adoption-of-net-zero-framework/ – From October 14–17, 2025, the Marine Environment Protection Committee (MEPC) of the International Maritime Organization (IMO) convened an extraordinary session in London to consider formal adoption of draft amendments to Annex VI of the International Convention for the Prevention of Pollution from Ships, including the IMO Net-Zero Framework. Following intense criticism and pressure from the United States, efforts to move the framework forward stalled, and the session ended with the decision to adjourn for one year without adopting the measures and reconvene in October 2026. This development pauses formal adoption but does not halt work on implementation, as the IMO advises that Member States will continue to work towards building consensus during the interim period. This delay, however, prolongs uncertainty for shipowners, financiers, and fuel suppliers who have been planning around the IMO’s forthcoming global greenhouse gas (GHG) regime and provides additional time for certain Member States to thwart efforts to close the remaining gaps.
