China's investment in renewable energy during the 12th Five-Year Plan period (2011-15) will reach 1.8 trillion yuan ($294 billion) in addition to 2.3 trillion yuan ($375 billion) on energy-saving and emission reduction.

"China has carried out a series of policies to cope with climate change and we have achieved some success after several years of effort," said Xie Zhenhua, Vice Minister of the National Development and Reform Commission, during the Caring for Climate China Summit held by the Global Compact Network China.

From 2006 to 2012, China's energy consumption per unit of the GDP was reduced by 23.6 percent, which equals a reduction of 1.8 billion metric tons of carbon emissions, according to Xie.

However, he admitted China's economic development depends heavily on high-energy consumption and produces high emissions, and that the country's emission per capita is higher than the global average.

"China will continue to make great effort to reduce emissions, improve air quality and accelerate sustainable economic development," Xie said.
