China's carbon intensity falls over 3.5 percent in 2012

China's carbon intensity, or its emissions relative to economic output, fell more than 3.5 percent in 2012, outperforming its average annual target, China's chief climate change official said on Thursday.

China aims to cut carbon intensity by 17 percent during the 2011-2015 period, which means an annual average target of around 3.5 percent. Intensity is the amount of carbon dioxide emitted per unit of gross domestic product.

"The situation last year was relatively good. Based on a preliminary estimate, China could achieve a more than 3.5 percent fall in carbon intensity," said Su Wei, director general of climate change department of National Development and Reform Commission.

Cutting carbon intensity allows China to meet international demands for it to curb emissions and also keep its priority that development must come first while many Chinese still live in poverty.
