Earlier this month, Panama’s Arsenio Dominguez sat beside Harry Conway as the Liberian chairman of the International Maritime Organization’s Marine Environment Protection Committee announced a historic agreement to target net zero emissions by 2050.

As director of the Marine Environment Division, Dominguez was happy to sit among the leaders soaking up the applause.

He was seen as the key IMO secretariat figure in helping the divergent member states achieve a difficult consensus after a long week of political bickering.
