when did the us ratify the kyoto protocol
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]
