In this research, the primary aim is to conduct a systematic review of the thematic evolution of green finance, which remains fragmented and unevenly represented in global academic debates. The objective of this analysis is to scientifically map out the scholarly output on green finance from 2015 to 2026, detailing its intellectual structure, trends, thematic clusters, and emerging lacunae in the field. Primary data extraction from Web of Science was employed to construct the bibliometric database, whereas the identification, screening, and selection of the final dataset were conducted in accordance with the PRISMA guidelines to ensure the study’s transparency and reliability. The main findings highlighted an increasing scholarly interest in the field’s publications from 2019 onward. Key occurrences and citation maps, using RStudio (version 4.1) and Biblioshiny (version 4.5.2), indicate dispersed clusters comprising sustainability transitions, digital finance, bibliometric methods, and a weak link to governance and behavioral perspectives. The co-authorship and country analyses confirm a pronounced geographic imbalance of green finance-related research in academia, with an overrepresentation in the Global North and an underrepresentation in Africa, Latin America, and the MENA region. The analysis further emphasizes the growing role of institutional and ESG regulatory frameworks in shaping research trajectories, while also identifying a limited integration of emerging technological dimensions such as digital finance and artificial intelligence. Thus, the study’s contribution to the literature relies on its critical understanding and structuring of the field’s evolution. The implications include synthesizing research gaps and the need for outcome-oriented impact assessments and mechanism-based models of green finance to ensure significant inclusivity and resilience in the subject’s future agenda.
