A newly released analysis of Chinese government data by the U.S. Energy Information Administration found over the past decade-plus, China consumed as much as 14% more coal on an energy-content basis than previously reported. Its domestic coal production meanwhile was as much as 7% higher between 2000 and 2013. The upward revisions are also a reminder of just how unreliable Chinese government data can be. It illustrates just how difficult it is to get an accurate historic account of China’s emissions of CO2 into the atmosphere. --The Wall Street Journal, 17 September 2015
