On November 18, environmental officials from the Major Economies Forum on Energy and Climate - informal climate negotiations initiated by President George W. Bush - ended two days of negotiations at an impasse over how to extend the Kyoto Protocols ahead of November 28 climate negotiations in Durban, South Africa. U.S. Special Envoy for Climate Change Todd Stern said that as of now Japan, Russia, and Canada are unwilling to commit to any substantive extensions, while the EU seems willing to move forward. Stern remained optimistic some kind of deal would be reached, and pointed out that developed nations will account for only 30-35% of greenhouse gas emissions by 2030, with the bulk coming from China, India, and other developing nations.
