The 84th session of the Marine Environment Protection Committee (MEPC 84) opened in London with a focus on reducing global shipping emissions and addressing critical marine environmental challenges. The meeting, organized by the International Maritime Organization, brings together Member States to discuss policies affecting international shipping and ocean sustainability.

Focus On Net-Zero Framework And Emissions Reduction

IMO Secretary-General Arsenio Dominguez urged countries to advance the IMO Net-Zero Framework aimed at cutting greenhouse gas emissions from ships. According to IMO data, the carbon intensity of international shipping has declined by over 38% since 2008, based on fuel consumption reporting submitted to the committee.

Delegates are reviewing technical measures such as greenhouse gas fuel intensity guidelines, fuel certification standards, and lifecycle assessment frameworks. Discussions also include emerging technologies like onboard carbon capture, wind propulsion systems, and monitoring of methane and nitrous oxide emissions.

Maritime Safety Concerns In Strait Of Hormuz

The session also highlighted ongoing risks in the Strait of Hormuz, where thousands of seafarers remain stranded due to geopolitical tensions. Officials noted that prolonged instability could increase the risk of maritime accidents and disrupt global trade and food supply chains.

The IMO reiterated the importance of freedom of navigation and called for diplomatic efforts to reduce tensions. The organization emphasized that seafarers should not be impacted by geopolitical conflicts.

Broader Environmental Measures Under Review

The committee is addressing multiple environmental priorities, including ballast water management, biofouling regulations, and marine plastic litter. Member States are expected to consider amendments to the Ballast Water Management Convention and adopt updated guidelines to prevent invasive aquatic species.

A draft 2026 strategy on marine plastic litter from ships is also under review, along with proposals for stricter regulations on the transport of plastic pellets and improved fishing gear marking systems.
