When Nature Counts: Corporate Biodiversity Attention and Access to Bank Finance

Business Strategy and the Environment, EarlyView.
ABSTRACT This paper investigates whether corporate attention to biodiversity influences firms' access to bank loans, an overlooked question in the emerging biodiversity–finance literature. Using a novel, text‐based measure constructed from 446 biodiversity‐related keywords and applied to Chinese A‐share listed firms from 2000 to 2023, we show that ...

Business and Biodiversity: Scaling Conservation Enterprises Within and Beyond Place for Transformative Change

Business Strategy and the Environment, EarlyView.
ABSTRACT Transformative change is required to address persistent and systemic drivers of biodiversity loss. There is an urgent need for innovative solutions that tackle root causes in place‐specific contexts. Evidence indicates that small, innovative, purpose‐driven businesses can serve as vehicles for developing place‐based solutions.
