The International Maritime Organization (IMO) has announced decisions on several key initiatives following the Marine Environment Protection Committee (MPEC 84) session, which was largely slowed by political maneuvering, as reported by The Maritime Executive on May 1, 2026. A central outcome is the adoption of a new North-East Atlantic Emission Control Area (ECA), described as the world’s largest such zone, expanding upon existing efforts in Northern Europe.

The ECA initiative began with 27 European Union member states and gained momentum as it progressed through IMO procedures. Iceland, the United Kingdom, and the European Commission also endorsed its launch, which was finalized during the committee session. The entry into force is set for September 1, 2027, with the ECA becoming fully effective 12 months later in 2028. The area extends 200 nautical miles offshore and covers a region from Greenland, Iceland, and the Faroe Islands in the north down to Ireland, the mainland of the United Kingdom, France, Spain, and Portugal. It will also connect existing ECAs in the Baltic, North Sea, and Mediterranean, as well as link with recently approved ECAs in the Norwegian Sea and Canadian Arctic.

The adoption introduces stricter emission limits for nitrogen oxides (NOx), sulfur oxides (SOx), and particulate matter. Vessels operating within the ECA will be required to use fuel with a sulfur content not exceeding 0.10 percent.

Among other key initiatives, MPEC adopted a strategy and action plan to address marine plastic litter from ships, focusing on improving port reception facilities and waste processing. This plan updates and replaces earlier efforts from 2021 and 2025. The committee also agreed to develop a mandatory code for transporting plastic pellets, known as nurdles, in freight containers, following several high-profile incidents where these pellets were released into the environment.

Additionally, MPEC adopted a package of amendments to the Ballast Water Management Convention, revising guidelines and requirements for developing ballast water management plans. Progress was also made on underwater radiated noise, with the committee agreeing in principle to extend the experience-building phase by two years, through the end of 2028, to help member states overcome barriers in applying previously adopted guidelines for reducing noise harmful to marine life.
