who must approve treaties made by the president
Treaty Clause The Treaty Clause is part of Article II, Section 2, Clause 2, of the United States Constitution, that empowers the President of the United States to propose and chiefly negotiate agreements between the United States and other countries, which, upon receiving the advice and consent of a two-thirds supermajority vote of the United States Senate, become treaties under international law.
Kyoto Protocol As of 2016, the US is the only signatory that has not ratified the Protocol.[98] The US accounted for 36% of emissions in 1990. As such, for the treaty to go into legal effect without US ratification, it would require a coalition including the EU, Russia, Japan, and small parties. A deal, without the US Administration, was reached in the Bonn climate talks (COP-6.5), held in 2001.[99]
