Representatives from think tanks of the BRIC countries (Brazil, Russia, India and China) discussed ways to fight climate change at a seminar here Wednesday.

The seminar, called BRIC Think-Tank Summit, gathered members of think tanks from the BRIC countries to examine the global economic situation and the role of BRIC countries in the post-crisis global transformation.

World countries need to take joint action to fight climate change, said Indian representative Samir Saran from the Observer Research Foundation.

Chinese representative Wu Enyuan, with the Institute of Russian, Eastern European and Central Asian Studies, Chinese Academy of Social Sciences, said the developed countries had a bigger responsibility on carbon emission reduction as the current climate change is a result of some 150 years of industrialization process of the developed nations.

But he said the developing countries, including the BRIC nations, should take their fair share of responsibility as well, and adopt measures to fight global warming.

"China has fulfilled its responsibility by taking practical actions in either energy conservation or environmental protection," he said, adding that other BRIC countries have also committed themselves to carbon emission reduction.

Brazil's representative Eduardo Viola said that implementing these measures is more important than holding discussions.

Russian representative Nikolai Mikhailov said climate change unveiled the notion that human beings can treat nature as they want without caring about the consequences.

Only a radical change in their attitude could make a difference, he said.

The two-day seminar was held on the eve of the second BRIC summit scheduled for Friday in the Brazilian capital.
