New Delhi, Feb 05 (ANI): Environmentalists and policy makers met at the 15th Delhi Sustainable Development Summit (DSDS) to set agendas for the 2015 climate change summit in Paris as India plays an influential role in UN climate talks. Paris could mark a shift away from two decades of climate diplomacy toward a more technocratic system that would allow national pledges for action to limit warming to be compared and toughened in coming years. Chairman of UN Intergovernmental Panel on Climate Change (IPCC), Rajendra K Pachauri, said that the three-day Delhi summit will be significant as far as the world's sustainable development goals were concerned.
