Definitions & Technical notes:
The UN Framework Convention on Climate Change was adopted on 9 May 1992. Five years later, on 11 December 1997, the Kyoto Protocol established legally-binding constraints on greenhouse gas emissions and "mechanisms" aimed at cutting the cost of curbing emissions.
This table signifies participation in the Framework Convention and Kyoto Protocol. Participation, in this table, means the country or area has become party to the agreements, which is achieved in a variety of ways depending on country circumstances, namely: accession, acceptance, approval, formal confirmation, ratification, or succession. Countries or areas that have signed but not become party to the agreements are indicated as non-participants.
The years refer to the date that participation was formalized. No value, '…', indicates non-participation according to the source at the time of the latest update.
The commitments of Annex 1 and non-Annex 1 participants in the Kyoto Protocol differ significantly. For more detailed country-specific information on the implications of participation, please visit: http://unfccc.int/.
