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.
Parties
Signing is optional, indicating an intention to ratify the Protocol. Ratification means that a state is legally bound by the provisions of the treaty. For Annex I parties (e.g. a developed state or one with an 'economy in transition') this means that it has agreed to cap emissions in accordance with the Protocol.
Iceland was the 55th state to ratify, fulfilling the first condition for coming-into-force. With Russia's ratification the "55 percent of 1990 carbon dioxide emissions of the Parties included in Annex I" clause was satisfied and the treaty was brought into force, effective 16 February 2005. As of October 2020, 147 states have accepted the Doha amendment. It will enter into force as of 31 December 2020.
