Rewiring Supply Chains Through Uncoordinated Climate Policy
Rewiring Supply Chains Through Uncoordinated Climate Policy
with Emanuela Benincasa, Olimpia Carradori, Miguel Ferreira
Abstract:
We show that climate transition risks can significantly disrupt supply chain networks. Specifically, suppliers affected by the California cap-and-trade program are more likely to lose customer relationships and less likely to form new ones compared to their peers unaffected by the program. The effects are more pronounced among suppliers facing high competitive pressure and producing standardized inputs. Additionally, affected suppliers experience declines in revenues, assets, and profitability. This supply chain rewiring induced by uncoordinated climate policies is consistent with carbon leakage, as customers exposed to the program through production networks show an increase in their supply chain emission intensity.
