本研究采用2004年的多区域投入产出模型，对世界范围内化石燃料燃烧引起的二氧化碳排放量进行了实证分析，分成三个超国家联盟，即G7、金砖四国和世界其他地区(ROW)。计算和比较了三个联盟的隐含排放强度，并分别使用市场汇率和购买力平价来考察名义生产效率和实际生产效率之间的差异。对体现在生产、消费、进口、出口等不同经济活动中的排放量进行了相应的计算和分析，具体揭示了与G7(盈余15.3亿吨，占其交易排放量的36%)和金砖四国(赤字13.7亿吨，占其交易排放量的51%)以及与ROW(赤字1.6亿吨，占其交易排放量的3%)相关的显著碳贸易失衡。与产业转移和国际贸易相关的碳泄漏在对全球气候政策的影响方面得到了说明。最后但并非最不重要的是，G7、金砖四国和ROW基于人均消费量的排放量分别确定为12.95吨、1.53吨和2.22吨，并讨论了灵活的减排政策以及人均应得权利的公平性。(C)2011爱思唯尔有限公司。保留所有权利。
Presented in this study is an empirical analysis of embodied carbon dioxide emissions induced by fossil fuel combustion for the world divided into three supra-national coalitions, i.e., G7, BRIC, and the rest of the world (ROW), via the application of a multi-region input-output modeling for 2004. Embodied emission intensities for the three coalitions are calculated and compared, with market exchange rate and purchase power parity separately used to investigate the difference between nominal and real production efficiencies. Emissions embodied in different economic activities such as production, consumption, import, and export are calculated and analyzed accordingly, and remarkable carbon trade imbalances associated with G7 (surplus of 1.53 billion tons, or 36% its traded emissions) and BRIC (deficit of 1.37 billion tons, or 51% its traded emissions) and approximate balance with ROW (deficit of 0.16 billion tons, or 3% its traded emissions) are concretely revealed. Carbon leakages associated with industry transfer and international trades are illustrated in terms of impacts on global climate policies. The last but not least, per capita consumption based emissions for G7, BRIC, and ROW are determined as 12.95, 1.53, and 2.22 tons, respectively, and flexible abatement policies as well as equity on per capita entitlement are discussed.
