An "Green Action Plan", including adopting low carbon technologies and saving resources with new management regulations, had been taken, Li said.

As a sign of the low carbon fervor, the three-day World Low Carbon and Eco-economy Conference, which ended here Sunday, has attracted 500 enterprises from 25 countries and more than 1,300 government officials, business executives, foreign ambassadors and international organization representatives.

The Conference passed a declaration on Wednesday, calling for all nations and businesses to develop low carbon and eco-economy to tackle global warming and other environmental issues.

Despite positive reactions from the public and industrial sectors, Chinese energy experts warned that China's road to industrialization through low-carbon path would be hard.

A report, jointly issued in September by more than 100 Chinese engery experts, said China might reduce the intensity of carbon dioxide emissions with a persistent policy of energy saving and emissions reduction.

But "without long-term sustentive technology transfers and financial support from abroad, it will be difficult for China to significantly reduce total carbon dioxide emissions," the report said.

It admitted uncertainties exist in changing the awareness of both the government and people, technical innovation, investment and international cooperation.

Wang Jianli, director of the Research Department of the Environmental Protection and Resources Conservation Committee, said China needs to borrow international experiences to promote low-carbon development.

Wang said China had solicited suggestions from multinationals when drafting laws and regulations on environmental protection circular economy.

Jiangxi Provincial government announced during the conference that the the province would cooperate with the Finland government to build a low carbon eco-city in Gongqing city by the Poyang Lake, China's largest freshwater lake.

The city covering six square kilometers was designed to accommodate 100,000 residents. The project will begin at the beginning of 2010 and be completed in 2013.

"China's urbanization process will bring millions of rural people into the cities. How to build cities for sustainable development is a challenge to China," said Mauri Tommila, whose company, Finland's DigiEcoCity Ltd, joined the eco-city project.

The company will build another eco-city in east China's Jiangsu Province and had begun negotiation with Shanghai and Beijing Municipal government for more eco-city plans, Tommila said.

Zhang Kunmin, vice president of Chinese Association on Sustainable development said low carbon development is a systematic and complex project, which requires the joint efforts of the Chinese government and companies as well as the international cooperation.

"China has a long way to go on the road of developing low carbon economy," Zhang said.
