From June 1 to 12, 2009, delegates from 182 countries met in Bonn, Germany, to discuss key documents that are to provide a basis for international negotiation of a post-Kyoto multilateral climate change treaty in Copenhagen, Denmark, in December 2009. The first document concerns the post-2012 emissionreduction commitments of industrialized countries. The second covers related issues such as the Kyoto flexibility mechanisms, including emissions trading and the Clean Development Mechanism.
