The Indonesia climate change trust fund (ICCTF) is designed as a national climate (trust) fund (NCF), which aims to develop innovative ways to link international finance sources with national investment strategies. National climate finance institutions (NCFIs) are mechanisms that enable governments to strengthen national political and fiscal systems through directing financing towards national climate change projects and programmes. The ICCTF was launched in 2009 and it is the first multi-donor trust fund established and governed by the government of Indonesia. This case study provides insight into the institutional set-up of a NCFI, and an overview of the evolution of Indonesia's climate change policy. The report details ICCTF funding sources, design, governance, administration and current operations. Amongst other key findings, the report notes that government policies need to be in place to lay the groundwork for the establishment of a national climate finance institution.
