ABSTRACT
The impact of corporate political spending on environmental policy has drawn numerous attention from researchers and policymakers. However, few studies have analyzed the empirical effect of corporate spending on environmental policy in aggregate. In this study, I analyze the impact of corporate independent spending bans on state environmental policy, utilizing the repeal of such bans in 23 states following the 2010 Supreme Court’s Citizens United decision as a research design. Through difference-in-differences tests, I find no evidence that the removal of independent expenditure bans influenced state environmental policy, regulations, or outcomes, or overall policy liberalism. I also find that corporate direct contributions did not increase in treated states, which may explain the lack of environmental policy effects. These results demonstrate that corporations did not utilize the new spending avenue after Citizens United to influence state environmental policy in aggregate and raise questions concerning corporate political spending and environmental preferences.
