According to a June 10 Nature report, Chinese national and provincial carbon inventory totals in 2010 were 1.4 gigatons apart, about 5 percent of annual global emissions. The report, “The Gigatonne Gap in China’s Carbon Dioxide Inventories,” examined Chinese inventories from 1997 to 2010, and found that emissions grew at an average annual rate of 7.5 percent according to national data and 8.5 percent according to provincial data. The widest gap was in the most recent report, 2010, when there was an 18 percent difference between the two totals.
