中国承诺“绿色发展”

China is the world's largest emitter of carbon pollution. But Beijing has worked to improve environmental management and reduce emissions in recent years.

China has pledged to embrace a "green development" model over the next five years, increasing the share of non-fossil fuels in the country's energy portfolio. The plan is to lean on wind, solar, biomass, water and geothermal energy. Beijing also says it will find cleaner ways of burning fossil fuels like coal.

China is already the global leader in clean energy investment. According to a newly released government report, the share of non-fossil fuels in primary energy consumption reached 11.2 percent in 2014. That's an increase of 1.4 percent from 2013. China has the biggest solar photovoltaic cell capacity and the largest wind power market. The amount of water power stations in China account for a quarter of the world's. The rapid development of clean energy has helped China's carbon emissions per unit GDP decline.

"From 2005 to 2014, China's energy consumption per unit GDP dropped 29.9 percent, and carbon dioxide emissions per unit of GDP fell 33.8 percent. During this period, the numbers of developed countries only went down about 15 percent, and the world average level did not change much. So it should be said that China has made great achievement in cutting carbon emissions, especially in cutting the emissions per unit of GDP,"  He Jiankun, deputy director of National Experts Committee on Climate Change, said.
