China should set different energy-reduction targets for regions with different energy intensity, a report by the International Low-carbon Economy Institute said on Friday.

"China has made a commitment to reduce energy consumption per unit of GDP by 16 percent by the end of 2015. But it is not fair to ask different provinces to commit to the same target," said Zhao Zhongxiu, director of the ILEI, which was jointly established by the University of International Business and Economics in Beijing and the University of Nagoya in Japan.

To set a reasonable target for various provinces, the report considered regional responsibility and reduction potential.
