China is the world's largest emitter（发射体） of carbon pollution．But Beijing has worked to improve environmental management and reduce pollution in recent years．
China has made a plan to be a"green development"model over the next five years，increasing the share of non﹣fossil fuels（非矿物燃料）．The plan is to use 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 new government report，the share of non﹣fossil fuels has reached 11.2percent in 2015．That's an increase of 1.4percent from 2014．China has the biggest solar photovoltaic cell capacity and the largest wind power market．The number of water power stations in China is about a quarter of the world's．The rapid development of clean energy has helped China's carbon emissions per unit GDP reduce．
"From 2005to 2014，China's energy use per unit GDP went down 29.9percent，and carbon dioxide emissions（二氧化碳排放） per unit of GDP went down 33.8percent．At that time，the numbers of developed countries only went down about 15percent，and the world average level did not change much．So it should be said that China has achieved a lot in cutting carbon pollution，especially in cutting the pollution per unit of GDP，"He Jiankun，deputy director of National Experts Committee on Climate Change，said．
