In decision B.37/21, the Board of the Green Climate Fund (GCF) approved the 2024 workplan of the Independent Evaluation Unit (IEU) of the GCF. The workplan includes, among other things, the undertaking of a synthesis on access, the results of which are presented in this report. The synthesis explores the broader context of access, extending beyond mere accreditation. The synthesis aims to develop and present analysis to inform the current discussion on access to the GCF, the strengths and weaknesses of the current approaches taken by the GCF, and, consequently, provide emerging ideas and way forward for improving access to the GCF.
