Delegates to the most recent round of United Nations climate talks said September 5 that a new negotiating stance from the United States, with support from China, India, and Russia, for the post-2020 period was emerging that called for flexible and dynamic rather than binding rules. The August 30-September 5 Bangkok talks, designed to set the stage for progress at this year’s 18th Conference of the Parties to the U.N. Framework Convention on Climate Change in Qatar, are the first time proposals for the post-2020 period have been discussed without referring to some type of binding action from all countries as agreed to in the Durban Platform at last year’s climate change summit.
