The Green Guarantee Group
The Green Guarantee Group (GGG) brings together governments, multilateral development banks (MDBs), the private sector, civil society, and a Wise Persons Group to chart a path toward greater uptake of guarantees.
Our Impact
Since its launch, the GGG has helped raise the visibility of guarantees as a central instrument for mobilizing private capital for sustainable development.
In 2024/2025, the GGG organized several events on green guarantees across three continents in the framework of major international fora, bringing together more than 400 participants.
The GGG has contributed to growing international recognition of guarantees in climate and development finance discussions, supported dialogue on key policy barriers, and launched the GGG Guarantee Directory as a public tool to improve market transparency.
