Mapping Global Research Trends on Green Sukuk and Blue Sukuk: A Bibliometric Analysis Using Scopus Data and Vosviewer

Abstract

This paper is a bibliometric mapping of the research trends on green sukuk and blue sukuk in the world through Scopus-indexed articles and visualized in VOSviewer. One hundred three hundred forty-four (134) documents published in 2016 through 2025 (year-to-date, as of September 2025) were reviewed in order to evaluate the rise in publications, the top-performers, institutions, countries, and direction of the field. The results show there will be a dramatic increase in the rate of scholarly interest, especially in the period of 2022–2025, and that green sukuk will become the most prevalent trend in research. The visualizations of networks and overlays show that the green sukuk, Islamic finance, sustainability, climate change, renewable energy, and the Sustainable Development Goals (SDGs) are strongly interconnected, which proves the tendency towards interdisciplinarity of the studied field. It is also analyzed that the output of the research is highly concentrated in particular countries and institutions with Indonesia as a leading country in issuing and discussing green sukuk academically. Blue sukuk, on the contrary, has a lack of bibliometric presence and is still at an early phase of practice and theoretical discussion. The present study will be useful to the literature in that it demonstrates the systematic knowledge mapping of the field, research frontiers, and strategic potential of green and blue sukuk as new tools of the Islamic sustainable finance.
