Carbon emissions embodied in demand-supply chains in China

Using the multi-regional input-output model (MRIO), the paper distinguishes the carbon emissions embodied in commodities for 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 MRIO for one country. Taking China as an example, based on MRIO tables for 1997 and 2007, CBEs, EBEs, and carbon emissions embodied in demand-supply chains for consumption and export at the sub-national level were analyzed respectively. The conclusion is, in China, transferred carbon emissions embodied in demand-supply chains driven by consumption and export both showed rapid growth during 1997-2007. And the net transferred carbon emissions embodied in the demand-supply chains showed an increasing trend also. Less developed regions with abundant fossil fuels tend to be a net outflow of carbon emissions.
