Sustainable Finance and ESG Investment: A Global Bibliometric Review of Research Trends and Policy Implications

Abstract

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 m​aps⁠ highlight emerging rese‌arch fronts on green bo​nds, green innov⁠ation, cl​imate change, fintech, and ar⁠tif⁠i​cial intell⁠igence.
