Abstract

This study investigates whether biodiversity risk disclosures reduce stock price crash risk, exploiting the Taskforce on Nature-related Financial Disclosures’ (TNFD) early adopter announcement as a quasi-natural experiment. Using a difference-in-differences framework, we find that TNFD adoption significantly reduces crash risk among Japanese firms. Our findings highlight biodiversity risk disclosures’ unique and complementary role, underscoring their importance in enhancing market transparency and mitigating downside risk.
