The United States has withdrawn support for the IMO's proposed global carbon tax framework, leading a coalition at the 84th Marine Environment Protection Committee (MEPC 84) session to advance pragmatic alternatives within the Net-Zero Framework.

On May 2, the United States officially withdrew support for the global carbon tax under the IMO's Net-Zero Framework during the 84th session of the Marine Environment Protection Committee (MEPC 84). The U.S. State Department led a coalition promoting alternative proposals focused on emissions performance targets and tiered compliance. This shift signals weakening backing for the original plan, described as a market-based regulatory system.
