How the AfDB Is Building a $1.5 Billion Climate Finance Machine — African Green Banks Initiative
For decades, Africa has faced a cruel paradox: the continent least responsible for global carbon emissions faces some of the most severe consequences of climate change, yet receives a fraction of the global finance needed to respond. A pan-continental initiative from the African Development Bank (AfDB) is now trying to permanently fix that equation.
The African Green Banks Initiative (AGBI), launched at COP27 in Sharm-el-Sheikh in 2022 and now in active deployment across the continent, is reshaping how climate capital flows into African markets. Working through a blended finance approach, the initiative comprises two core financing windows – a Technical Assistance facility and a Green Finance Facility – and is targeting the creation of a $1.5 billion ecosystem of green investment facilities by 2030.
The scale of the problem AGBI is trying to solve is staggering. The projected cost of implementing African countries’ Nationally Determined Contributions, their national climate commitments under the Paris Agreement, is estimated at roughly $2.8 trillion by 2030, requiring an average of $250 billion annually.
Yet the numbers actually flowing into the continent fall far short. Despite being one of the most climate-vulnerable regions in the world, Africa receives just 3% of global climate finance. In 2021, only $30 billion was mobilized on the continent, representing less than 5% of total climate investment worldwide, with private sector participation accounting for less than 15% of that total.
The gap, in other words, is not simply about money. It is about architecture, the absence of credible, bankable structures that give private investors the confidence to deploy capital at scale.
What a Green Bank Actually Does
Green banks and green investment facilities are blended financial instruments, either placed within existing financial institutions or built from scratch, designed with the technical and financial capacity to attract climate finance from both international and local investors. They overcome traditional investment barriers by making potential climate projects more attractive and less risky.
The AfDB’s framework gives governments and financial institutions technical assistance, fundraising support, and co-financing opportunities for green projects, while providing credit enhancement solutions to reduce risk and mobilize both public and private sector investment.
Audrey-Cynthia Yamadjako, coordinator of the initiative, has argued that green finance facilities are the essential bridge between ambition and action. She described them as “the solution to bring private finance at scale in climate action through the translation of the $2.8 trillion NDC implementation needs into well-structured and bankable projects.”
The initiative was successfully piloted in Benin and Côte d’Ivoire, partnering with La Caisse des Dépôts et Consignations du Bénin and the National Investment Bank of Côte d’Ivoire respectively. It has since expanded north, with new partnerships with Commercial International Bank in Egypt and Crédit Agricole du Maroc in Morocco.
The initiative also finances green banks that already exist. In a notable recent example, the AfDB joined the Green Climate Fund in raising concessional funding for Rwanda’s green bank, Ireme Invest, contributing to its total capitalisation of $142 million alongside development agencies from Denmark, France, the UK, and Sweden, as well as the European Investment Bank.
AGBI was launched alongside the Climate Investment Funds, Canada Climate Action, the Green Bank Network, asset manager Amundi, and the Multilateral Cooperation Center for Development Finance.
The Blended Finance Logic
The central bet of AGBI is that public money, deployed strategically, can unlock multiples of private capital. The challenge is not so much a global shortage of climate finance as it is that African institutions and governments need to develop clear climate strategies incorporating blended finance models that can de-risk investment and allow private sector participation.
AfDB Vice President Kevin Kariuki has previously described the initiative as “a powerful tool for reducing financing costs and mobilising private sector investments in climate action in Africa,” noting that green banks have significant potential for attracting new catalytic funds when supporting low-carbon, climate-resilient development.
The initiative was designed to help increase Africa’s access to global climate finance from the current 3% to 10% annually by 2030.
A Race Against the Clock
Ms. Yamadjako has been direct about the urgency: “We cannot wait any longer to solve the lack of climate finance in Africa.” With COP30 already behind us and African nations still underfunded relative to their climate commitments, the AGBI now enters what may be its most critical years — proving whether institutional architecture alone can move the needle on a financing gap that dwarfs most national economies.
African domestic public resources are expected to contribute roughly $277 billion toward NDC implementation by 2030, covering only around 10% of total need. The rest must come from somewhere. For the AfDB, green banks are that somewhere.
