- Abstract
Domestic intermediate input-related carbon emissions (DII-CEs) are present in high amounts and have significant reduction potential. Reducing the DII-CE is becoming a priority as part of decarbonizing China's exports. Previous studies have not addressed the significant heterogeneity of DII-CE components stemming from different inter-sector production linkages. This study applies an integrated analysis framework to characterize the heterogeneous DII-CE components. We identify the composition of sector-level DII-CE responsibilities, and verify the emission hotspots, driving forces, and emission rebound effects across heterogeneous DII-CE components in China's exports from 1997–2017. The study reveals the following key findings: (1) The proportion of DII-CEs increased from 82.27% to 86.29% in China's exports; and Telecommunication and electronic equipment (MS20), Chemicals (MS12), and Electric equipment and machinery (MS19) evolved as the three primary DII-CE contributors. (2) Based on the evolution of sector-level DII-CEs, 11 crucial export sectors are identified. (3) Along with the spillover component, the feedback component is another potential crucial source of sector-level DII-CEs. (4) The role of the emission coefficient in determining DII-CE reduction has been replaced by the production mix, which has not achieved its full reduction potential. (5) Rebound mitigation measures are needed for all DII-CE components of crucial export sectors, particularly for their internal components, which have exhibited a strong backfire effect.
