This publication is a history of the partnership between Indonesia and the Asian Development Bank (ADB). When Indonesia became a founding member of the bank in 1966, the country faced daunting challenges. In the five decades that passed, both Indonesia and ADB have evolved in remarkable ways. Indonesia developed rapidly through the late 1990s yet faced a difficult time of adjustment after the Asian financial crisis of 1997–1998. The country has since resumed growth in the last decade. For its part, ADB has widened its activities in Indonesia, transforming from a project-oriented bank into a broad-based development institution. This effective partnership reflects Indonesia’s success in working with the international community in the past 50 years.

A large financing need challenges climate-adjusted infrastructure in developing Asia, estimated at $26 trillion till 2030. This necessitates crowding-in private sources to meet financing, efficiency, and technology gaps. However, a lack of bankable projects is a major hurdle. This publication suggests one possible innovative financing approach. The Green Finance Catalyzing Facility (GFCF) proposes a blended finance framework for governments and development entities to better leverage development funds for risk mitigation, generate a pipeline of bankable green infrastructure projects, and directly catalyze private finance. The GFCF provides useful inputs for the current debate on mainstreaming green finance into country financial systems.
