A U.S.-centric Chronology of the International Climate Change Negotiations
The Copenhagen conference in December 2009 achieved only mandates to continue negotiating toward the next Conference of the Parties (COP) to be held in Mexico City in December 2010. As a background to these proceedings, this document provides a U.S.-centric chronology of the international policy deliberations to address climate change from 1979-2009. Negotiations underway since 2007 have run on two tracks, the Kyoto Protocol the Convention under the Bali Action Plan. Many in the U.S. Congress are concerned with the goals and obligations that a treaty or other form of agreement might embody. For U.S. legislators, additional issues include the compatibility of any international agreement with U.S. domestic policies and laws; the adequacy of appropriations, fiscal measures, and programs to achieve any commitments under the agreement; and the desirable form of the agreement and related requirements, with a view toward potential Senate ratification of the agreement and federal legislation to assure that U.S. commitments are met.
A U.S.-centric Chronology of the International Climate Change Negotiations
The United States is a Party to the United Nations Framework Convention on Climate Change (UNFCCC), but not to its subsidiary Kyoto Protocol. Negotiations under way since 2007 have run on two tracks: one under the Kyoto Protocol, to extend commitments of developed parties beyond 2012, and the second track under the UNFCCC, regarding commitments for all Parties. Both tracks convened in Copenhagen, Denmark, in 2009 under a deadline to agree on steps to address climate change beyond 2012. As background for congressional deliberations, this document provides a U.S.-centric chronology of international climate change policy from 1979 to 2010. This chronology identifies selected external events and major multilateral meetings that influence both the current legal and institutional arrangements, and the contentious choices about future international cooperation.
