The Pacific Elders’ Voice (PEV) will be meeting in London on 1st July 2023. The timing of this meeting falls between two important events of the International Maritime Organisation (IMO) – the 15th Intersessional Working Group (ISWG 15) meeting, being held from 26th to 30th June, and the 80th Marine Environment Protection Committee (MEPC80) meeting, being held from 2nd to 7th July. The MEPC80 meeting potentially signifies international shipping’s last chance to ensure a strategy that is aligned with a 1.5°C trajectory, as had been agreed in the Paris Agreement. The PEV meeting is themed “Ramping Up Ambition in IMO: Looking to the Future through the Past.”
