As of June 2013, there are 192 parties to the Kyoto Protocol to the United Nations Framework Convention on Climate Change, which aims to combat global warming. This total includes 191 states (189 United Nations member states as well as the Cook Islands and Niue) and one supranational union (the European Union).[1][2] Canada renounced the protocol effective 15 December 2012 and ceased to be a member from that date.
With the Protocol's 2008-2012 commitment period expiring, the Doha Amendment to the Kyoto Protocol was agreed to, which establishes new commitments for the period 2013–2020. As of October 2020, 147 states have accepted this amendment.
