Berlin: As Prime Minister Manmohan Singh prepares to ask the developed world at the G8 summit on Friday to share responsibility for fighting climate change, U.S. President George W Bush on Thursday insisted that efforts to reduce greenhouse gas emissions would not succeed until India and China were involved.

Mr. Bush emphasised the need for creating a bridge between Europe and developing countries such as India and China to ensure reduction of greenhouse gas emissions.

"By 2008, the world's emitters of greenhouse gases should come together," he told journalists.

"Nothing is going to happen in terms of substantial reduction unless China and India participate," he said. "If we want them [India and China] at the table, it is important that we give them the opportunity to set an international goal."

India's stand

India has held that countries responsible for creating the problem should come out in a big way to solve it. It argues that even today the greenhouse gas emissions of developed countries are many times more than that of developing countries.

Dr. Singh is expected to remind the developed countries that as agreed in the U.N. Framework Convention on Climate Change, they should act in accordance with their "common but differentiated responsibilities and respective capabilities." He is also likely to state that climate change concerns should be integrated with development strategies.
