Seeking a constructive approach to move forward in the global efforts to combat climate change, Prime Minister Manmohan Singh today said India is willing to do more provided there are credible arrangements from rich nations on financial support and technology transfers. In a statement before his departure for Copenhagen today, Dr Singh said climate change cannot be addressed by perpetuating the poverty of the developing countries. Prime Minister's remarks come as negotiations in Copenhagen have hit a roadblock with no headway being made on agreement on emission cuts, mitigation targets and financing.
