Using the multi-regional input-output model (MRIO), the paper distinguishes the carbon emissions embodied in commodities for domestic final consumption (CBEs, consumption-based emissions) and those for export (EBEs, export-based emissions), and then calculates carbon emissions embodied in the demand-supply chains for consumption and export based on technical coefficients matrix of the MRIO for one country. Taking China as an example, we provide a dynamic analysis of CBEs, EBEs, and carbon emissions embodied in consumption and export demand-supply chains at the sub-national level based on the MRIO tables for 1997 and 2007. The results show that, in China, the transferred carbon emissions embodied in demand-supply chains driven by consumption and export both showed rapid growth during [1997][1998][1999][2000][2001][2002][2003][2004][2005][2006][2007]. And the net transferred carbon emissions embodied in the demand-supply chains showed an increasing trend as well. Less developed regions with abundant fossil fuels tend to net flow out carbon emissions.

Abstract:In the era of globalization and international trade, the production-based CO 2 emissions accounting system, proposed by United Nations Framework Convention on Climate Change, can easily lead to a "carbon leakage" issue. Thus, the accounting of consumption-based carbon emissions and carbon emissions embodied in international trade has received considerable research attention. Nevertheless, researchers also indicated that the consumption-based principle has some weaknesses, for example, it leads the producers inert on reducing carbon emissions while gaining economic benefits. To share carbon emissions responsibilities between producers and consumers is widely recognized. So, setting an income-based emissions accounting method as to producer is a necessary complement for accounting national carbon emissions. This study promoted a model, called the value-added-based accounting of CO 2 emissions method, to account for anthropogenic CO 2 emissions within the context of the economic benefit principle. Based on the global multi-regional input-output table and national carbon emissions database, we calculated the national/regional carbon emissions based on the value-added accounting approach as well as the amount of global carbon emissions embodied in value-added chains. If the results are served as a supplement for calculating the amount of CO 2 emissions reduction that a country is responsible for, problems such as carbon leakage and resistance to improving the energy efficiency of exporting sector may be solved, because all the supply chains emissions associated with the economic growth of a country would be considered.
