The International Maritime Organization (IMO) will hold the 84th session of the Marine Environment Protection Committed in London from April 27 to May 1, 2026. As reported by splash247, the meetings are expected to be a critical step toward finalizing global shipping’s climate framework.
Discussions will again center on the Net Zero Framework (NZF), which failed to secure adoption in October 2025, despite being agreed in principle earlier that year. The IMO has since set November 2026 as the deadline to finalize and adopt a global climate agreement, according to reporting from ShippingWatch.
The most divisive element remains a proposed global carbon pricing mechanism, estimated to generate $10–12 billion annually, according to Splash247. Negotiations have involved 62 countries, with 39 nations focused on how carbon revenues would be managed and distributed.
According to The Maritime Executive, the United States has called on the IMO to halt work on the framework. Japan has proposed removing carbon pricing entirely, while Saudi Arabia, the UAE, Russia, and Argentina have pushed to eliminate carbon taxes and ease fossil fuel phase‑out targets, as reported by splash247.
In contrast, the European Union (EU), along with Norway, Brazil, and several small island states, continues to support the framework and carbon incentives. However, internally, the EU consensus is not complete. gCaptain reported that Greece, Malta, Italy, and Cyprus previously abstained from or declined to support certain negotiating positions.
Shipping industry groups are urging the IMO to deliver a single global regulatory framework to avoid fragmented regional rules. Organizations including BIMCO, the International Chamber of Shipping, the World Shipping Council, and several others are advocating for a single global regulatory approach, warning that overlapping national measures could distort competition, according to The Maritime Executive.
Separately, the world’s three largest flag registries, representing roughly 50% of global shipping tonnage, called on the IMO to consider different approaches alongside the NZF, supported by classification societies Bureau Veritas and RINA, as reported by The Maritime Executive.
Beyond pricing, talks also cover strengthening the Carbon Intensity Indicator (CII) and updating Life Cycle Assessment (LCA) guidelines to better capture methane emissions and broader environmental and social impacts, as reported by the American Journal of Transportation.
These debates carry long-term implications for fleet investment. ShippingWatch reported that commercial vessels typically operate for 20 to 25 years, heightening concerns around regulatory certainty.
