The 84th session of the IMO’s Marine Environment Protection Committee (MEPC 84) held extensive discussions on the Net-Zero Framework (NZF). This was the first opportunity to do so following the adjournment of the extraordinary session in October 2025. Although there were divergent positions on key elements such as establishing a fund, MEPC 84 agreed to continue discussions on a revised framework to ensure consensus. MEPC 84 also progressed on key technical guidelines supporting the NZF. As part of the review of the Ballast Water Management (BWM) framework, amendments to the BWM Convention were approved, strengthening survey and other mandatory requirements.
