The summit which is scheduled to take off on Wednesday, Jul 8 in Italy, will bring the world leaders together to deliberate on the global climate change issue and may lead to a new global climate pact.
Noting that the climate is an important issue, Singh said, "What we are witnessing today is the consequence of over two centuries of industrial activity and high consumption lifestyles in the developed world. They have to bear this historical responsibility."
The issue of climate change and a pact on the carbon emissions has been a hot topic between the developing countries and the industrialized nations.
India like China is refusing to commit to emission cuts in a new treaty unless developed countries like United States present their targets on emission cuts.
The same goes for all the G8 nations who want to see others commit to the cuts before they sign a treaty.
