A coalition of Pacific island nations wants to raise $500m (£400m) to make all shipping in the Pacific Ocean zero carbon by the middle of the century.
The Pacific Blue Shipping Partnership, announced on Tuesday by the governments of Fiji, the Marshall Islands, Samoa, Vanuatu, the Solomon Islands and Tuvalu, has set an emissions reduction target of 40% by 2030, and full decarbonisation by 2050.
