Post-Kyoto negotiations refers to high level talks attempting to address global warming by limiting greenhouse gas emissions. Generally part of the United Nations Framework Convention on Climate Change (UNFCCC), these talks concern the period after the first "commitment period" of the Kyoto Protocol, which expired at the end of 2012. Negotiations have been mandated by the adoption of the Bali Road Map and Decision 1/CP.13 ("The Bali Action Plan").
