Sustainable finance is a rapidly evolving field of finance which has gained prominence for emphasizing investments that guarantee goals for sustainable development. Sustainable finance has become one of the most influential sectors in the world due to its growing modern developments in the financial industry. Although sustainable finance is a popular topic in the literature on sustainability, there is a dearth of systematic bibliometric analysis that offers a thorough evaluation of the area, clarifies the state-of-the-art, analyses new prospects, and offers potential guidelines for additional research. With this view, the study aims to comprehensively examine the sustainable finance as a research field over past twenty years by conducting a bibliometric analysis of 640 publications between 2003-2023 from the SCOPUS database. In order to identify the most significant authors, universities, countries, journals, reference papers, and prominent keywords and to learn about the research topics that researchers have been working on recently, the study intends to highlight collaborations between authors, universities, and countries in the field.
