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).
