China has stated that outcomes from the Copenhagen climate conference to be conducted in December 2009 will be crucial if worldwide reductions in carbon emissions and global warming are to be seen.

The Chinese foreign ministry’s climate-change negotiator Yu Qingtai said the country will remain optimistic regarding the conference outcome.

Qingtai said that the US and other developing nations should set targets for decreasing pollutants, however, China itself is not prepared to fix such a target.

Instead, Qingtai said China’s emissions surge would depend on the availability of natural sources, the adoption of new technologies and economic growth.

The success of the Copenhagen conference hinges on the consent of developed nations for larger carbon emissions reductions and the sharing of eco-friendly technologies with developing countries that should still have a right to grow and prosper, such as China and India, Qingtai said.

He added that China and India’s suggestion for a 40% decrease in emissions was reasonable.

According to Qingtai, China’s five-year goal is to decrease power usage-per-unit of gross domestic product by 20% by 2010. It will do this by increasing power efficiency, reforestation and using renewable sources.

China and the US account for 40% of the world’s greenhouse gas emissions.
