How long has it been Donald Trump returned to occupy the office of president of the United States reiterated its firm no to the draft regulation ( of 9 April and 13 August 2025).

In the run-up to the MECP meeting that is expected to the approval of the regulation, the announcement of the vote against the USA was reaffirmed on Friday in a statement joint letter of the Secretary of State, Marco Rubio, the Secretary of State to Energy. Chris Wright, and the Secretary of Transport, Sean Duffy, with the unequivocal title: "Intervening to defend America from the first global tax on carbon emissions of the United Nations - the Net-Zero Framework of the International Maritime Organization.

"President Trump - reiterated Rubio, Wright and Duffy - made it clear that the United States will not accept any international environmental agreement that unduly burdens or unfairly on the United States or harms the interests of the people American. Next week, IMO members will vote on the adoption of the so-called NZF, aimed at reducing emissions global carbon dioxide emissions of the international maritime sector. This will be the first time that a United Nations imposes a global tax on carbon emissions on Worldwide. The Administration unequivocally rejects this proposal to the IMO and will not tolerate any initiative that increases costs for our citizens, suppliers shipping companies and their customers, or for tourists. The economic impact of this measure could be disastrous, with some estimates predicting an increase in the costs of Global shipping up to 10% or more. We ask you to join to us in rejecting the adoption of the NZF at the October meeting and to work together for our economic and economic security. collective energy system".

As usual for the Trump administration, with the statement, as well as urging the other states to oppose the project of the regulation, it threatens to retaliate against those countries that will support the adoption of the Regulation, a measure that is denounced as a "neocolonial export of global climate change led by Europe". Especially Rubio, Wright and Duffy have announced that several actions starting from the conduct of "investigations and the examination of potential rules to tackle anti-competitive practices in flagged countries and the potential blocking of access to to US ports to ships registered in those countries', by the imposition of "visa restrictions, including an increase in of fees and processing procedures, requirements mandatory new interviews and/or revisions of visa quotas C-1/D for seafaring crew members' and the imposition of 'trade sanctions resulting from U.S. government contracts, including those for new ships Commercial, terminals and natural gas infrastructure liquefied vessels, and/or other financial penalties on ships flying flag of nations in favor of the NZF". In addition, it threatens to "impose additional port fees on ships owned, managed or flying the flag of countries that support the framework" and, "among other measures under consideration, to assess sanctions against officials sponsoring climate policies promoted by activists that would burden American consumers".

"Our fellow members of the IMO - it is the final intimidation of Rubio, Wright and Duffy - should be warned".
