Donald Trump's administration is pressuring vulnerable countries to oppose measures that would require shipping companies to pay for their carbon emissions. US officials have written to supportive nations and made phone calls threatening tariffs, visa restrictions, and other retaliatory actions.
The International Maritime Organization (IMO) is meeting in London this week, where member states are expected to approve new rules levying charges on ships based on greenhouse gas emissions. The pricing mechanism could raise an estimated $10bn annually from 2028, marking the first time shipping firms pay for climate damage.
Although the carbon levy was approved in April, it must be reaffirmed by two-thirds of IMO member states. The US, alongside petrostates like Saudi Arabia, UAE, and Qatar, is working to block the measure. A US diplomatic document lists potential retaliatory measures, including tariffs, port levies, and visa restrictions.
Several countries, including the Philippines, Turkey, Argentina, and Australia, are reportedly reconsidering their positions. The outcome could hinge on a small number of votes, with some nations potentially flipping their support due to US pressure or Saudi offers of economic incentives.
