• The IMO’s Net‑Zero Framework up for a London vote would price shipping emissions and establish a Net Zero Fund, with adoption requiring a two‑thirds majority of member states voting.
• The United States, working with Saudi Arabia, is pushing to replace the IMO’s usual “tacit acceptance” with “explicit acceptance,” a shift industry sources say could stall entry into force.
• Major shipping groups, including the UK Chamber of Shipping, have urged governments to back a single global rule to avoid a fragmented patchwork of national and regional regulations.
• Experts say that if the measure passes and the U.S. stays out, participating states could inspect and detain noncompliant foreign vessels, making the system difficult for the U.S. to evade.
