This study aims to map the intellectual structure of sustainability in financial management decision-making with a focus on environmental considerations, covering thematic evolution, collaboration patterns, and emerging research frontiers. A quantitative bibliometric approach was employed using data retrieved from the Scopus databases, spanning publications from the 2000s to 2026. VOSviewer software was used to conduct co-authorship and keyword co-occurrence analyses. Decision making emerged as the central integrating node across thematic clusters including risk management, investment, and sustainable finance. Co-authorship networks reveal fragmented yet globally connected collaboration, with the United States and United Kingdom as primary hubs. Keyword overlay visualization confirms a decisive research shift from conventional financial approaches toward technology-integrated sustainability, including fintech and artificial intelligence. Practitioners and policymakers should prioritize cross-disciplinary frameworks that combine financial performance metrics with environmental risk assessment to achieve adaptive and sustainable decision-making. This study provides a comprehensive bibliometric mapping of sustainability-finance research, identifying structural knowledge gaps and articulating an agenda for empirical and comparative future inquiry.
