Purpose This study aims to explore the potential of Islamic climate finance in Indonesia and to map Islamic climate finance based on Islamic finance instruments, both commercial and social. Design/methodology/approach The analysis was conducted in Jakarta, Indonesia, between October 2022 and June 2023. This study adopted a qualitative interpretive approach in two phases. The first phase was desk-based research which focused on document analysis such as official documents, scientific publications, non-governmental organization publications and company reports in Indonesia. This analysis was conducted to identify significant milestones in developing green and eco-friendly finance that used Islamic financial instruments in Indonesia. The second phase consisted of interviews with essential Islamic climate finance project actors, such as green sukuk publishers, zakat and waqf collection agencies, stakeholders, capital market regulators, Shariah supervisory boards and Islamic finance experts. Findings The main finding of this study is that the development of Islamic green finance in Indonesia can occur through various channels, including greening Islamic capital markets, greening Islamic social finance, Islamic green finance and developing green banking services for the unbanked to support financial inclusion. Green sukuk, or Islamic bonds, are key financial instruments in Islamic green finance. They are used to fund projects in areas such as clean energy, mass transit, water conservation, forestry and low-carbon technology. These green financing initiatives also include socially responsible investments that are designed to improve the lives of people and communities. Research limitations/implications First, the availability of data on Islamic green finance practices in Indonesia may be limited, making it difficult to obtain a comprehensive understanding of the current landscape. Second, cultural and religious factors may play a role in the adoption and implementation of Islamic green finance, and these factors may vary across different regions in Indonesia. Practical implications The exploration and clustering of Islamic climate finance based on Islamic financial instruments in Indonesia can lead to the development of more sustainable and environmentally friendly practices in the financial industry. Originality/value This study serves as a pioneering effort to explore the potential and clustering of Islamic climate finance based on Islamic financial instruments in Indonesia.
