This document presents the Executive Summary of the Independent Evaluation of the Green Climate Fund’s Project Preparation Facility (PPF2026), which provides the GCF Board and Secretariat with an independent, evidence-based assessment of whether the PPF, as currently designed and implemented, is fit for purpose, coherent with the Fund’s broader suite of modalities, and positioned to effectively support access to the GCF through high-quality, country-driven funding proposals. It assesses relevance, effectiveness, efficiency, coherence, and emerging impacts. The summary, in particular, outlines the key findings, conclusions, and recommendations of the evaluation.
