The United States on Friday threatened to impose sanctions and take other punitive action against any country that votes in favor of a carbon tax on maritime transportation to be implemented through a UN agency.

“We will fight hard to protect our economic interests by imposing costs on countries if they support” the Net Zero Framework, said a joint statement by US Secretary of State Marco Rubio and his counterparts at the departments of energy and transportation.

Members of the London-based International Maritime Organization (IMO) are set to vote next week on the adoption of the Net Zero Framework (NZF) agreement aimed at reducing global carbon emissions from the shipping sector.

Washington, however, described the proposal as imposing “a global carbon tax on the world.”
