Significantly improving access is a core operational commitment of GCF under the updated Strategic Plan for the GCF 2024–2027. Accreditation, as one of the core access modalities, needs to be brought in line with the level of organizational maturity for the second replenishment period of GCF. This document presents the revised accreditation framework in response to the Board mandate in decision B.37/18, paragraph (r), to ensure enhanced access to GCF financing. It also includes critical implementation and transitional measures and outlines system boundaries of accreditation reform.
