This bill, titled the "UNtaxed Act," establishes significant limitations on the ability of the United Nations and its affiliated bodies to impose financial burdens on the United States. It specifically prohibits any tax, tariff, fee, or penalty from being levied upon United States citizens or companies by the UN unless the Senate has provided its advice and consent to the underlying agreement. The legislation further restricts the use of U.S. funds, preventing their appropriation or availability for contributions to the UN or any UN-affiliated body if those funds would be used to impose a global carbon tax . This also applies to funds intended for the implementation or enforcement of such a tax. A "global carbon tax" is defined as a tax under a global fuel regime that requires vessel owners to reduce greenhouse gas emissions and imposes costs based on those emission levels.
