Negotiations at the International Maritime Organization (IMO) have collapsed without consensus on the long-awaited Net-Zero Framework (NZF), leaving the global shipping industry facing renewed uncertainty over the timeline and structure of its decarbonisation pathway.
Delegates meeting at the extraordinary session of the Marine Environment Protection Committee (MEPC) in London were unable to reconcile differing positions on how to implement the framework, which aims to translate the IMO’s 2023 greenhouse gas strategy into a legally binding roadmap.
Stalemate Over Market Measures and Deadlines
The talks reportedly faltered over key elements of the proposed framework, including carbon pricing mechanisms, fuel standards, and the timeline for enforcement. While a majority of member states supported adopting a global levy on shipping emissions, a bloc led by Saudi Arabia, the United States, and several developing countries raised procedural objections and called for further impact assessments before implementation.
Proponents argued that an early adoption of the NZF is crucial for providing clarity and investment signals to shipowners, fuel producers, and port authorities. However, opponents expressed concern that premature regulation could raise operating costs, distort trade competitiveness, and disadvantage developing economies lacking access to green fuels or infrastructure.
Industry Left in Limbo
The delay means that global shipping — responsible for roughly 3% of total greenhouse gas emissions — remains without a unified policy instrument to steer its transition to net-zero emissions by 2050.
Analysts warn that postponing the decision could slow down investment in low-carbon technologies and sustainable fuel production, as the absence of regulatory certainty makes long-term planning difficult for shipowners and financiers.
Regional Measures May Fill the Gap
In the absence of a global agreement, several regions and industry coalitions are expected to advance their own initiatives, such as the EU Emissions Trading System (EU ETS) and green corridor partnerships led by ports and operators. These fragmented approaches, however, risk creating regulatory divergence and uneven costs across the sector.
Next Steps
The IMO has agreed to reconvene formal negotiations at the MEPC 84 session in early 2026, with an intersessional working group tasked with refining technical and economic proposals.
Observers note that the extra year could allow for more extensive modelling and compromise-building but warn that further delays would undermine the credibility of the IMO’s decarbonisation commitments.
Outlook
With climate pressures mounting and regional regulations tightening, the failure to adopt the Net-Zero Framework marks a significant setback for the maritime sector’s global climate agenda. Stakeholders now face a prolonged period of policy ambiguity, testing the industry’s ability to stay aligned with international climate goals while maintaining operational and economic stability.
