China’s top climate negotiator is “not very optimistic” about the results of Durban climate change talks, Reuters reported, citing state radio. The Kyoto Protocol which came into force in 2005 commits most developed countries to binding emissions targets. The latest talks in Durban are the last chance to set another round of targets before the first commitment period expires in 2012. There are widespread differences among the major parties. “Now the prospects are not very optimistic. However, at least in developed countries, the European Union has expressed willingness to consider the second commitment period of the Kyoto Protocol,”said Su Wei, China’s negotiator. Envoys said there may be a political deal struck with a new set of binding targets. China, the world’s top carbon emitter, has said it is unwilling to make any commitments until the US does. Additionally, Russia, Japan and Canada have said that they will not sign up unless the biggest emitters do, too.
