Warsaw: In a last ditch effort to save climate talks from collapse, heads of delegations of key countries on Friday stepped up behind-the-scenes parleys to commit something on financial assistance so that the goal to Paris for a final deal two years from now remains within reach. It is likely that the Conference of Parties (COP) on climate change, which was scheduled to conclude on Friday, may continue the marathon ministerial round, leaving the floor open till Saturday morning. The Indian side has already made it clear that New Delhi won’t compromise on its position when the final draft of the talks comes for approval on Friday night. Environment minister Jayanthi Natarajan may question the approach of the developed countries more emphatically through her intervention during the marathon round if the rich nations don’t give a definite timeline to fulfill their promise. She had made her intent clear during her formal speech a day before when she said non-capitalization of Green Climate Fund (GCF) was a matter of serious concern and it threatened the “credibility of the global negotiation process”. Delegates of different countries, who have been part of various negotiations, told the TOI that the US stand continued to be quite rigid on setting up a mechanism for loss and damage and giving any definite timeline to begin capitalization of the GCF — a $100 billion annual kitty that is to be filled by rich nations — which is meant for adaptation and reduction of emissions by poor countries to fight the menace of climate change. Natarajan said, “Till now, no roadmap has been agreed to by developed countries to mobilize $100 billion annually by 2020 as agreed in Cancun.” Amid all-round criticism for blocking the crucial matter of finance, the US is, however, likely to move a bit so that the climate talks should not be termed as a failure on the key issue. US special envoy for climate change Todd Stern, while addressing a press conference on Friday, gave such a hint and said capitalization of the fund would start an year from now.
