From 1-4 September 2026, the 22nd meeting of the intersessional working group on reduction of greenhouse gases from shipping took place at the IMO Headquarters in London. We were represented throughout the full week. Below is an account of the discussions, potential and hurdles following a week of intensive multilateral negotiations. This was the first working group (WG) meeting during which new terms of reference that were agreed at MEPC 84 in the spring, were up for discussion.

Based on our observations, it appears that there may no longer be universal agreement on the strategy’s ambition and indicative checkpoints. Disagreements on central parts of a future framework are of s
