Our study explores the relationship between climate risk awareness and the use of green buildings among corporations. Using a sample of firms from the ESG Active Universe over a 10-year period, the findings indicate that firms which are aware of their climate risk are more likely to adopt green building practices. Additionally, corporate social responsibility (CSR) strategy and the presence of an environmental management team were identified as significant mediators in this relationship, emphasizing the importance of internal corporate mechanisms in driving sustainable initiatives. Policy implications suggest that while regulatory mandates are crucial, voluntary corporate practices motivated by climate risk awareness can significantly complement these efforts, leading to more widespread adoption of green buildings. Policymakers should therefore consider encouraging and supporting such voluntary initiatives alongside mandatory regulations to enhance corporate contributions to sustainable development.
