The main purpose of this legislation, known as the UNtaxed Act, is to limit the ability of the United Nations and its affiliated organizations to impose a global carbon tax on the United States. The bill aims to protect U.S. citizens and companies from being subject to taxes or fees imposed by international bodies without the approval of the U.S. Senate. Key provisions of the bill include a prohibition on any taxes, tariffs, fees, or penalties being levied on U.S. citizens or companies by the United Nations unless these measures are part of an agreement that has been ratified by the Senate.
