Integrating Environmental, Social, and Governance (ESG) factors into investment decisions is receiving increasing attention amid global sustainability challenges. Real options theory provides a framework for incorporating ESG into corporate finance under uncertainty. This study conducts a bibliometric analysis of 50 peer-reviewed Scopus articles from the past decade, focusing on ESG and real options in Asia. Using keyword mapping, we identify key research clusters and themes. Findings show a growing but nascent field, highlighting corporate sustainability strategies, ESG metrics in valuation, and regulatory impacts. Insights benefit academics, policymakers, and practitioners navigating ESG uncertainties in Asian markets.
