ABSTRACT This paper presents a systematic bibliometrics review of green finance literature, examining how financial innovation mechanisms—particularly green bonds, ESG integration, and climate-linked instruments—are driving sustainable development goals (SDGs). Our analysis encompasses 342 peer-reviewed articles published between 2014 and 2025 from Scopus and Web of Science databases. The study addresses three critical research questions: (a) Which green finance instruments are most extensively studied and how has research focus evolved? (b) What theoretical frameworks and quantitative models dominate the assessment of green finance's environmental impact? (c) What are the critical gaps in understanding green finance's effectiveness in bridging the climate finance gap and achieving SDGs? Findings reveal that while green bonds represent 67.3% of research focus, significant research gaps exist in understanding implementation challenges in emerging markets, behavioural finance dimensions of sustainable investing, and standardised impact measurement frameworks. Our bibliometrics analysis identifies ESG integration and climate risk assessment as the fastestgrowing research domains (312% increase 2020—2025), while post-investment impact verification remains critically understudied. The paper concludes with recommendations for developing context-specific green finance frameworks for emerging economies and establishing unified global impact reporting standards.
