New version ! hal.science/hal-05047276 =>Climate regulation bolsters (rather than crowds out) NGOs climate activism against firms. #Econsky
Climate Regulation and Civil Society Activism
This paper investigates how public climate regulation shapes NGO activism against firms. Using monthly data on NGO campaigns across 78 countries (2010–2023), we find that the enact- ment of executive regulations significantly increases firm-targeted climate activism. Event-study estimates show no anticipatory trends and reveal a persistent, rising response. Consistent with our framework, the impact of regulation is larger in weaker enforcement environments and among nationally oriented NGOs with the capacity to act on domestic institutions. Public regulation thus mobilizes civil society as an informal enforcement layer, extending climate governance be- yond formal state action.
