Marked by the failure to achieve a binding agreement in Copenhagen, new polarization in climate diplomacy has emerged out to develop a complementary policy position for a comprehensive and legally binding agreement at the 16th conference of the Parties in Cancun and beyond.It was commonly expected that the Copenhagen Climate Conference would result an equitable, legally binding agreement setting targets of ambitious emission reduction, adequate and predictable finance for adaptation and technology transfer, and would provoke a path of green development to avoid dangerous climate change impacts now and in future. This process has started since 13th Conference of the Parties held in Bali in December 2007, where Bali Action Plan was adopted by the country Parties to progress the negotiation until Copenhagen.
