IMO Intersessional Working Group Reconvenes to Debate Net-Zero Framework
Delegates at ISWG-GHG 22 in London address ongoing divides surrounding fuel pathways, transition costs, and decarbonisation ambition.

The International Maritime Organization has resumed formal discussions on maritime decarbonisation as its 22nd Intersessional Working Group on Reduction of Greenhouse Gas Emissions from Ships convenes in London. Scheduled to run from 1 to 4 September, the four-day meeting brings international delegates together to negotiate the future structure and details of the Net-Zero Framework.
The talks proceed amid persistent differences among member states regarding the ambition and mechanics of the regulatory measures. Central to the agenda is the ongoing effort to align diverse international perspectives on how the maritime sector should structure its midterm decarbonisation policies.
A significant portion of the working group's deliberations focuses on alternative fuel pathways and the associated financial implications for global shipping. Participants continue to navigate divisions over projected compliance costs, the selection and evaluation of viable zero- and near-zero-emission fuels, and the economic instruments designed to support the transition.
As the ISWG-GHG 22 sessions progress, the discussions are anticipated to lay critical groundwork for upcoming regulatory milestones. The negotiations highlight the challenges of establishing unified global rules that balance environmental objectives with commercial and economic feasibility across the international fleet.
