Resumen
In November 2009, China pledged a 40?45% decrease in CO2 emissions per GDP by 2020, as compared with the 2005 level. Although carbon intensity (emission) targets by nature are ambiguous, this study demonstrates that China?s pledge is consistent with the current Chinese domestic agenda that simultaneously pursues economic growth and energy security. The target numbers in the pledge seem reasonable, given the technological feasibility and measures, considered along with the assumption that moderate economic growth will occur. However, the study also argues that financial and institutional constraints exist as potential obstacles to achieving the target if the trend of the current economic tendencies continues.
