Green Guarantee Group
About
The Green Guarantee Group (GGG) was soft-launched at COP28 by Germany’s Federal Foreign Office and the former Ministry for Economic Affairs and Climate Action, now Ministry for Economic Affairs and Energy. The GGG is chaired by Professor Lars-Hendrik Röller, Chairman of the Berlin Global Dialogue and former Chief Economic Advisor to Chancellor Angela Merkel (2011–2021). Since March 2025, Nigeria is serving as a co-chair, represented by Mr. Faruk Yabo, Permanent Secretary in Nigeria’s Federal Ministry of Solid Minerals Development.
The European Climate Foundation (ECF) and Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) serve as the GGG Secretariat, led by Morgan Deprés, Executive Director of International Finance, Economy and Nature Programmes at ECF. The Secretariat supports the high-level engagement and political outreach of the Co-Chairs with strategic partners across key international fora and events — including the COPs, FfD4, the HSC and IMF/ World Bank Annual and Spring meetings. In addition, it coordinates the work of the GGG’s core bodies — the Wise Persons Group and the Technical Expert Group — and ensures the delivery of all key events and activities, including flagship reports, stakeholder engagement, knowledge exchange, and external communications.
Climate Policy Initiative (CPI) serves as a high-level advisor and analytical partner to the GGG, helping to identify key challenges and innovative solutions related to guarantees. CPI will also support the identification of “lighthouse projects” to unlock climate investment and provide recommendations to scale green guarantees ahead of COP30.
