Abstract:

By using the multi-regional input-output analysis, the agricultural intermediate input greenhouse gas (GHG) emissions in 30 provincial regions of China (Hong Kong, Macao, Taiwan and Tibet excluded ) in 2007 and 2017 were measured. The crucial source sectors and crucial intermediate sectors for agricultural intermediate input GHG emissions were identified and their reduction potentials were further revealed. It was shown that the agricultural intermediate input GHG emission accounted for 73.9%-89.5% of agricultural embodied GHG emissions in 2007-2017. Thirteen crucial source sectors and 13 crucial intermediate sectors for agricultural intermediate input GHG emissions were identified in 2007 and 2017, respectively. The distribution of these identified sectors exhibited decentralization trend. Based on the data of 2017, the 13 crucial source sectors had greater emission reduction potential than that of the 13 crucial intermediate sectors.
