Those supporting the deal hope it will raise billions to help poor countries deal with climate breakdown

Brazil has asked the UN to throw out plans for a new levy on global shipping that would raise funds to fight the climate crisis, despite playing host to the next UN climate summit.

The proposed levy on carbon dioxide emissions from shipping will be discussed at a crunch meeting of the International Maritime Organisation (IMO) that begins on Monday. Those supporting the deal, including the UK, the EU and Japan, are hoping the levy will raise billions of dollars a year, which could be used to help poor countries cope with the effects of climate breakdown.
