US blocking tactics delay global shipping carbon levy talks

the us is blocking formal adoption of a global carbon levy on shipping, even though a majority of countries agreed to it a year ago. the levy was meant to be a key step in cutting emissions from international maritime trade. the legal mechanism to adopt the deal is now stuck in limbo. the us hasn't offered a counterproposal — it's just refusing to move forward. the talks are part of the imo's broader effort to price shipping emissions, but without consensus, the timeline keeps slipping. other nations are frustrated but haven't found a way around the us blockade.
