Countries have agreed a global deal to tackle shipping emissions, after nearly ten years of negotiations.
The agreement covers the vast majority of the world's commercial shipping and means that starting in 2028, ship owners will have to use increasingly cleaner fuels or face fines.
The deal was nearly derailed after Saudi Arabia forced a last minute vote and the US pulled out of talks in London – but it eventually passed on Friday.
Small island states and environmental groups were angry that a blanket tax was not agreed to and called the deal "unfit for purpose".
