A decade in the making, its emissions-trading system is now live
CHINA IS THE world's biggest polluter. Its cars and factories release almost twice as many lung-harming carbon particles each year as in those in America. The country's leadership has certainly been sending strong messages on cutting emissions. But its plan to reduce the carbon intensity of GDP by 65% by 2030 (compared to 2005 levels) and to hit net-zero emissions by 2060 has done little to comfort environmentalists.
