Background to the IMO Net‑Zero Framework

The International Maritime Organization is finalising a Net‑Zero Framework (NZF) that aims to curb greenhouse‑gas emissions from global shipping. While the draft sets out ambitious reduction pathways, it has sparked vigorous debate over which fuels should be permitted under future regulations.

DiBella’s case for LNG and bio‑LNG

Laura DiBella, chair of the United States Federal Maritime Commission (FMC), used a Thursday statement to argue that any workable NZF must retain “the widest possible range of alternative marine fuels”. She highlighted both conventional liquefied natural gas (LNG) and its renewable counterpart, bio‑LNG, as essential to meeting emission targets while preserving fuel security.

DiBella stressed that “fuel diversity does not necessarily equate to fuel availability, stability, and reliability”, warning against a framework that limits options based on narrow assumptions. Instead, she called for emissions reductions to be linked to the “viability, affordability, global availability and scalability” of fuels rather than a rigid implementation date.

Quantifying the potential impact, DiBella asserted that LNG and bio‑LNG together could realistically supply **over 60 % of global maritime fuel by 2050**. She noted that bio‑LNG, derived from organic agricultural waste, can utilise existing LNG bunkering infrastructure, offering a “responsibly sourced, American‑made” pathway for vessels already equipped for gas propulsion.

Addressing cost concerns, the FMC chair rejected the notion that rising demand would inevitably push bio‑LNG prices higher. She explained that such an outcome presumes a static supply curve; a well‑designed global fuel standard, she argued, would create “long‑term demand certainty” and unlock new investment, particularly in the United States where LNG export capacity is projected to **double by 2030**.

Industry reaction and looming IMO discussions

The Loadstar reported that DiBella warned the current NZF draft “risk[ed] restricting the fuel choices available”, describing it as an initiative that “raises more questions than it answers” and must be rethought before international acceptance. This criticism aligns with broader industry concerns about a regulatory regime that could lock out proven alternative fuels.

ship.energy highlighted DiBella’s insistence that inclusion of “market‑proven alternative fuels, such as bio‑LNG”, is key to delivering effective emissions reductions for both the shipping sector and end consumers. The outlet also pointed out that two Intersessional Working Group meetings—scheduled for **1–4 September** and **23–27 November 2026**—will be convened to hammer out remaining details of the NZF.

These sessions follow a technical meeting slated for next month at the IMO, where delegates are expected to address outstanding concerns over fuel standards, market readiness and compliance timelines. The convergence of FMC statements and upcoming MEPC (Marine Environment Protection Committee) workshops signals an intensifying policy dialogue as the sector seeks clarity on permissible fuels.

Implications for supply chains and infrastructure

If DiBella’s forecasts materialise, LNG and bio‑LNG will dominate bunkering demand, compelling ports and fuel suppliers to expand gas handling capacity. The FMC chair underscored that bio‑LNG can be introduced through the same storage and regasification facilities used for conventional LNG, reducing capital outlays for retrofits.

She also highlighted the United States’ emerging role as “the world’s leading LNG exporter”, suggesting that American‑sourced bio‑LNG should receive recognition both domestically and internationally. This positioning could influence trade flows, encouraging operators to source gas from U.S. terminals that are expanding export volumes in line with the projected doubling of capacity.

From a regulatory perspective, DiBella’s call for a “global fuel standard” aims to provide market participants with certainty, thereby incentivising private investment in bio‑LNG production facilities and associated logistics networks. The expectation is that a clear standard will mitigate price volatility by aligning supply growth with demand projections.

What this means for operators

Ship owners and charterers should monitor the outcomes of the September and November Working Group meetings, as any amendment to the NZF could dictate fuel eligibility, documentation requirements and compliance timelines. Operators already equipped for LNG may find a smoother transition if bio‑LNG gains formal recognition, allowing them to leverage existing gas bunkering contracts while diversifying their fuel mix.

In practice, this means reassessing bunker procurement strategies to incorporate bio‑LNG suppliers, especially those linked to U.S. export terminals that are scaling capacity. Forward‑looking operators may also consider investing in dual‑fuel engine retrofits or newbuilds that can seamlessly switch between conventional LNG and renewable bio‑LNG, thereby hedging against future regulatory shifts.

Finally, the emphasis on a stable, affordable supply chain suggests that firms should engage early with fuel standardisation bodies to influence criteria that affect certification and pricing. Early alignment with the emerging global standard could secure more favourable contract terms and reduce exposure to potential fuel‑supply disruptions as the industry moves toward its 2050 decarbonisation goals.
