Cheng, chairman of the International Finance Forum and former vice chairman of the Standing Committee of China’s National People’s Congress, made the remarks at the onging World Economic Forum’s annual Summer Davos meeting in the northern Chinese city of Tianjin.
China needs to improve fossil energy efficiency and also develop new energy, Cheng said. He cited his research results as saying that pollution cost 34.5 percent of the gross domestic product in 2005.
China is also committed to promoting carbon trade, he said. "The critical problem now is to find the most suitable carbon trading market." The economist also proposed carbon tax to promote sustainable growth.
"We are suggesting imposing carbon tax on thermal power plants and using the revenue to subsidize solar and wind energy development," Cheng said.
China’s wind power installed capacity is expected to hit 40 GW by the end of 2010, and further up to 200 GW by 2020, said Li Junfeng, deputy director with Energy Research Institute.
