The gigatonne gap in China’s carbon dioxide inventories
Dr. Hubacek and his Chinese collaborators found a gap the size of Japan's annual CO2 emissions in China's declared carbon emissions. They compiled the carbon dioxide emission inventories for China and its 30 provinces for the period 1997 - 2010 and found a big difference between official Chinese datasets of the National Bureau of Statistics. One set presented energy use for the nation, the other for its provinces. The paper identifies a 1.4-billion ton emission gap (in 2010) between the two datasets. This implies greater uncertainties than ever in Chinese energy statistics.
