THE UN's International Maritime Organisation (IMO) is facing difficulties effecting compliance of global shipping with stricter emission rules, reports Bloomberg.
"It's going to be difficult if nothing of substance comes out these meetings," said former IMO emissions chief Edmund Hughes.
IMO state carriers transports more than 80 per cent of the world's internationally traded goods and has a carbon footprint bigger than Germany and the Netherlands combined.
The three Pacific Island nations are calling for the IMO to recognise that international shipping must reach zero greenhouse-gas emissions by 2050.
The IMO's official target is due to be revised in 2023 and is for only a 50 per cent cut by 2050.
