Abstract

This study examines the association between firm-level biodiversity risk exposure and accounting comparability using a sample of U.S. firms. Our findings yield several important insights. First, we document a negative relationship between biodiversity risk exposure and accounting comparability, indicating that greater exposure to ecological degradation is associated with lower comparability of accounting information. Second, we show that board characteristics and climate change exposure play important moderating roles in this relationship. Specifically, stronger governance structures, reflected in larger boards and greater separation between the roles of CEO and chair, are associated with heightened managerial attention to biodiversity issues, improved internal monitoring, and reduced information asymmetry, thereby mitigating the decline in accounting comparability. In contrast, higher climate change exposure amplifies the adverse effect of biodiversity risk on accounting comparability. Against the backdrop of growing concern over biodiversity risk, these findings offer timely insights for policymakers and corporate leaders seeking to better understand and manage its broader financial and operational consequences.
