According to the Task Force on Climate-related Disclosures, firms that compose the polluting sectors might be vulnerable to reputation risk. In this work, we investigated the effect of climate-related announcements of listed companies on their equity performance. Focusing on the major historical greenhouse gas equivalents emitters, we studied the effect of companies’ climate-related social media activity on their daily abnormal returns in general and during climate-related events. Results suggest that climate-related announcements expose firms to abnormally negative returns. Sensitive external events and political rallies coincided with negative stock returns within investor’s expectations.
