The United Nations Framework Convention on Climate Change (UNFCCC) entered into force in 1994, aimed at reducing greenhouse gas concentrations in the atmosphere. The Conference of the Parties (COP) was designated as the supreme governing body of the Convention.
To date, 195 countries have submitted their instruments of ratification. These countries meet once a year, during two weeks, in order to evaluate the application of the Convention and develop the negotiation process between the Parties in front of new commitments.
