NEW DELHI: Developed countries, particularly the US, should take the lead in cutting emissions as they are mostly responsible for global warming, says environmentalist R K Pachauri who is "cautiously optimistic" about a consensus on combating climate change in the December Copenhagen summit.
Pachauri, the Chairman of Inter-governmental Panel on Climate Change (IPCC), said: "One would like to see much greater initiative from them (developed countries), certainly the US is one of them. All the developed countries would have to collectively do something that is meaningful."
In an interview to PTI, Pachauri said the developed countries are largely responsible for global warming problem and so they have to take the lead in reaching to a consensus on the agreement.
However, he did not see the industrialized world as an "obstacle" in this regard.
"I am cautiously optimistic because there is a lot of political understanding among the leaders of the world that action is essential, so I expect in the end, they will come together," he said about the probability of Copenhagen agreement on Climate Change being held to chalk out a strategy to deal with global warming.
