Xia, C., Zheng, H., Meng, J. et al. Outsourced carbon mitigation efforts of Chinese cities from 2012 to 2017. Nat Cities

Objective:

• Investigate outsourced carbon mitigation efforts at city level by comparing carbon mitigation contributions of both local and outsourced efforts in supply chains

Case:

• Cities, China

Methodology:

• Leontief
• Structural decomposition

Data Source

• CEADs: City MRIO
• CO2 emissions: Shan

Findings:

• The increase concentrated in a few super emitters, where are the centers of population and economic activity

• The increase is highly concentrated in service sector, while others decreas.

• Outsourced emissions rising from 78.6% in 2012 to 81.9% in 2017.

• Decrease in carbon intensity drove emissions down; improved production structure led to lower emissions; and the increase in final demand led to an increase in emissions

• The contribution of carbon intensity change in upstream cities was greater than the local mitigation.
