This paper explores how firms respond to pressures from both private and public politics in the context of climate change. It examines the conditions under which firms adopt practices consistent with the goals of social movements, particularly in response to shareholder activism and regulatory threats. The study finds that firms are more likely to engage in practices aligned with social movement goals if they or other firms in their industry have been targeted by shareholder resolutions or face regulatory threats. These findings extend existing theories by showing that both activist groups and government actors can influence organizational practices. The paper also highlights the spillover effects of these pressures, where firms not directly targeted may adopt new practices due to the broader context of industry-level changes. The study uses data from the Carbon Disclosure Project (CDP), which collects information on greenhouse gas emissions and climate change strategies from large public companies. The analysis focuses on whether firms disclose this information to the CDP, using a logistic regression model to examine the effects of private and public politics on corporate disclosure practices. The results show that firms targeted by shareholder resolutions are more likely to disclose information, as are firms in industries where other firms have been targeted. Additionally, firms headquartered in states with proposed greenhouse gas regulations are more likely to disclose information. The paper also examines the influence of regulatory threats on corporate behavior. Firms facing potential regulatory changes are more likely to adopt new practices consistent with social movement goals. The study finds that regulatory threats have both direct and spillover effects, influencing not only targeted firms but also other firms in the same industry. The findings contribute to the growing literature on social movements and organizations by showing how both private and public politics can lead to changes in corporate practices. The study also highlights the importance of political context in shaping corporate responses to activism and regulation. Overall, the paper provides empirical and theoretical insights into how firms respond to pressures from social movements and government regulation in the context of climate change.This paper explores how firms respond to pressures from both private and public politics in the context of climate change.
