The International Maritime Organization has approved a global fuel emissions standard, imposing fees on ships that breach it and rewarding those burning cleaner fuels. Despite US threats to pull out of climate talks, the deal aims to reduce net emissions from international shipping by 20% by 2030 and eliminate them by 2050. The scheme charges $380 per metric tonne for extra CO2-equivalent emissions above a fixed threshold and $100 per tonne for emissions above an even stricter limit, generating up to $40bn in fees by 2030. Industry groups welcome the deal, while critics say it falls short of needed measures.
