The decision leaves the global shipping industry facing renewed uncertainty in its decarbonization pathway.

At the extraordinary session of the Marine Environment Protection Committee (MEPC) held in London this week, IMO member states failed to reach consensus—or call a vote—on draft amendments to MARPOL Annex VI, which include the key elements of the proposed Net-Zero Framework.

Delegates voted to adjourn discussions for 12 months, meaning the framework cannot be adopted before late 2026 at the earliest. The delay complicates the implementation of the IMO’s Greenhouse Gas (GHG) Reduction Strategy, adopted in 2023, which targets net-zero emissions from international shipping by 2050.

The Net-Zero Framework, approved in principle at MEPC 83 in April 2025, is designed around two central pillars: a global fuel standard and an emissions pricing mechanism. Together, these are intended to provide the regulatory foundation for the shipping sector’s transition toward zero-carbon operations.

While the main negotiations have been paused, the Intersessional Working Group on GHG Emissions Reduction from Ships—scheduled to meet from October 20 to 24—will continue developing technical implementation guidelines to maintain momentum toward eventual adoption.

Industry groups have expressed deep disappointment over the outcome of the talks.

The Global Maritime Forum described the adjournment as “a serious setback.”

“Delaying for a full year makes delivery of the sector’s decarbonization targets even more challenging,” said Jesse Fahnestock, the Forum’s Director of Decarbonization. “We urge member states to reconfirm their commitment to multilateralism and to continue the urgent work of developing a regulatory framework that can deliver on the IMO’s GHG strategy.”

The International Chamber of Shipping (ICS) echoed this frustration.

“We are disappointed that member states have not been able to agree a way forward,” said Thomas Kazakos, ICS Secretary General. “Industry needs clarity to make the investments necessary to decarbonize in line with the IMO’s goals.”

From Denmark, Anne Steffensen, CEO of Danish Shipping, emphasized:

“We came here to finally conclude a crucial climate agreement for international shipping. This is not the outcome we hoped for—it’s a big disappointment after years of effort.”

The decision to postpone adoption of the Net-Zero Framework until 2026 marks a significant setback in global efforts to decarbonize maritime transport, which currently accounts for around 3% of global CO₂ emissions. Still, many stakeholders remain hopeful that continued technical discussions will preserve momentum and pave the way for a landmark climate agreement in the near future.
