The Board-approved workplan of the IEU (document GCF/B.34/28) commissioned the independent evaluation of the GCF’s Readiness and Preparatory Support Programme (RPSP) to assess the progress, results and outcomes, effectiveness, and efficiency of its operational processes. This additional deliverable of the evaluation was submitted at B.36 originally as an annex to IEU’s Activity Report (GCF/B.36/Inf.09), and this standalone version was created to enable stakeholders’ direct and easy access to the IEU’s B.36 deliverable under the RPSP evaluation. It is based on key findings from previous evaluations, a preliminary review of the landscape, evidence related to internal structure relevant to GCF’s RPSP, and some strategic reflections.
