US–EU Dispute Over Global Shipping Emission Reductions Escalates Before IMO Vote

Tensions have escalated between the United States and the European Union ahead of a crucial International Maritime Organisation (IMO) vote on a proposal to achieve net-zero emissions from global shipping by mid-century. The EU supports the framework as a vital climate milestone, while the US opposes it, arguing it would effectively impose a global carbon tax and drive up shipping costs by 10%. Washington has even threatened sanctions and port bans against nations backing the plan. The framework would set the world’s first global price on ship emissions, encouraging cleaner fuels and sustainable maritime operations. If approved, it would take effect in 2027, with payments starting in 2029. Shipping, which carries most global trade, contributed 1.4% of global greenhouse-gas emissions in 2024.
