谁的估计更准确?评论Nature发表的中国CO_2排放重估的论文

Which estimation is more accurate? A technical comments on Nature Paper by Liu et al on overestimation of China's emission

从温室气体清单估计的方法、数据及不确定性等几个方面,对刘竹等2015年8月发表在Nature上的论文"Reduced carbon emission estimates from fossil fuel combustion and cement production in China"的主要结论及观点进行了分析,指出了该文在计算与比较中的错误,因而该文有关中国国家温室气体清单高估中国排放的结论并不成立。

Liu et al report an overestimation of carbon emission from fossil fuel combustion and cement production in China. We test the robustness of their findings from various aspects on methodology, data and uncertainty. We found their findings contains serious mistakes and misunderstanding on inventory methodology and energy data. Thus casting daout on their conclusion that previous studies overestimate China＇s carbon emission.
