IMO launches global talks on net-zero shipping rules
The International Maritime Organization (IMO) has launched a critical round of negotiations to finalise binding global regulations aimed at achieving net-zero emissions in international shipping by 2050.
Speaking at the opening of the 83rd session of the Marine Environment Protection Committee (MEPC 83), IMO Secretary-General Arsenio Dominguez highlighted the progress made on a draft IMO Net-Zero Framework. The proposed measures include mandatory cuts to ships’ greenhouse gas (GHG) fuel intensity, a global emissions pricing scheme, and the creation of an IMO Net-Zero Fund.
The fund would support the adoption of zero and near-zero emission fuels and technologies, while ensuring that developing countries benefit from a just and equitable energy transition.
Dominguez praised member states for their commitment and collaboration: “I have no doubt you will achieve the necessary compromise so that, by the end of the week, we can take another significant step forward in delivering the goals of the IMO GHG Strategy.”
These measures are set to be integrated into Annex VI of the International Convention for the Prevention of Pollution from Ships (MARPOL), which covers 97% of the world’s merchant fleet. A final draft is expected by 11 April, with legal adoption targeted for October 2025.
Tackling Marine Pollution Beyond Carbon
In addition to climate action, MEPC 83 also addressed wider environmental concerns. Key outcomes include the adoption of a 2025 Action Plan to combat plastic litter from ships, interim guidance on biofuel carriage, and updated guidelines on hazardous materials inventories and ship biofouling.
The committee will continue discussing the designation of new Emission Control Areas (ECAs) and Particularly Sensitive Sea Areas (PSSAs), as well as reviewing the Ballast Water Management Convention.
