This study conducts a global bibliometric review of research on sustainable finance and ESG investment using data from the Scopus database for the period 2000–2025. Descriptive indicators and science-mapping techniques—co-authorship, co-citation, and keyword co-occurrence analyses—were applied through VOSviewer and Bibliometrix. The results show that “sustainable development,” “ESG,” “sustainable finance,” “finance,” and “investments” constitute the main intellectual core of the field, with strong emphasis on the ESG–financial performance nexus. Density and overlay maps highlight emerging research fronts on green bonds, green innovation, climate change, fintech, and artificial intelligence. Author, institutional, and country networks reveal highly internationalized collaboration patterns, with China, the United States, and several European and Asian countries acting as key hubs. The study offers practical insights for investors and policymakers seeking to align capital allocation with sustainability goals and provides a roadmap for future research on technology-enabled ESG analytics, transition finance, and the experiences of developing economies.
