Shipping industry braces for prolonged delay in IMO’s Net Zero Framework amid geopolitical divisions

A show of hands at a high‑level Singapore Maritime Foundation New Year Conversations panel made plain the mood in the room: senior Asian shipping executives largely expect a delay well beyond the IMO’s stated one‑year adjournment of its Net Zero Framework. According to Seatrade Maritime, virtually no hands were raised in favour of the framework being merely a one‑year setback, with most attendees anticipating a longer deferral as the industry faces renewed geopolitical friction over the rules that will govern shipping’s decarbonisation pathway.

The extraordinary Marine Environment Protection Committee (MEPC) session in October 2025 ended with a vote to adjourn consideration of the Net Zero Framework for 12 months, and the IMO has said it will reconvene the MEPC in October 2026 while technical work continues in intersessional groups to build consensus. The framework, which the IMO approved in principle at MEPC 83 in April 2025, bundles a global fuel standard with a global greenhouse‑gas emissions pricing mechanism. According to the IMO press briefing, member states will continue working towards consensus and developing implementation guidelines during the adjournment.

Yet the political realities that surfaced in London are unlikely to vanish quickly. Industry observers said the October meeting exposed sustained opposition from influential states. Seatrade Maritime reported that the United States lobbied strongly against adoption at the extraordinary session, and petro‑states led by Saudi Arabia were cited as instrumental in securing the adjournment. Independent reporting of the vote shows the decision passed narrowly, with 57 countries in favour and 49 against, underscoring a deeply divided membership.

For shipowners, operators and their suppliers, the consequences are immediate and practical. Uncertainty over a global standard and a single carbon pricing mechanism increases the risk of fragmented regulatory regimes emerging at national and regional level. Seatrade Maritime noted that China already operates a regulation for domestic trade that could be extended internationally in months, and the panel warned that similar bilateral or regional measures, mirroring the EU Emissions Trading Scheme, may proliferate. The industry risks a “messy” compliance landscape in which operators must navigate overlapping, potentially conflicting rules while capital expenditure choices on new tonnage and fuel systems are deferred or hedged.

Timing for any eventual entry into force has shifted, too. Technical analysts point out that the adjournment pushes the earliest realistic entry date outwards; DNV has estimated that implementation could not occur before 1 March 2028 at the earliest if the framework is adopted when MEPC reconvenes. That horizon matters for chartering strategies, shipbuilding slots and the financing of alternative‑fuel bunkering infrastructure, all of which require multi‑year lead times.

Panel participants, speaking under Chatham House rules, said the framework may need substantive redrafting and that some elements could return to the drawing board, a process that would take several years. At the same time, they stressed the continuing need for standardisation of technical rules for new fuels independent of the economic instruments designed to fund research and development. Legal advisers and industry bodies have likewise emphasised that ongoing intersessional work will focus on practical guidelines for implementation even as political agreement remains elusive.

The practical upshot for industrial decarbonisation professionals is twofold. First, companies must plan for regulatory fragmentation and design compliance and fuel strategies that are resilient to a patchwork of national and regional measures. Second, market actors and financiers should accelerate parallel work on fuel production, supply chains and port‑side infrastructure to avoid lock‑in to fossil‑intensive assets should national measures move faster than the global regime. Industry groups and classification societies continue to publish scenario analyses and technical guidance to help firms manage transition risks during the interregnum.

While the IMO frames the adjournment as an opportunity to build a stronger consensus, the narrow vote margins and public lobbying behaviour signal that geopolitical divisions will shape the pace and form of shipping’s transition for the foreseeable future. As regulatory authority fragments, the industry will need to balance advocacy for a unified global approach with pragmatic investments to comply with an increasingly diverse regulatory environment.
