AfDB Climate Action Window Funding Opportunity for African NGOs

The AfDB Climate Action Window funding opportunity is one of the African Development Bank Group’s largest climate grant mechanisms for low-income and climate-vulnerable countries in Africa.

Managed through the African Development Fund (ADF), this window was created to finance large, high-impact climate programmes that can operate at national or regional scale rather than as isolated pilot projects.

This call is most relevant to African NGOs and development partners already working in agriculture, water security, renewable energy, transport, and climate resilience who need substantial financing to expand or institutionalise their work.

It is designed for projects that align with national climate commitments, particularly Nationally Determined Contributions (NDCs) and long-term development strategies.

With a submission deadline of 25 February 2026 (23:59 GMT), this is a time-sensitive opportunity for organisations capable of managing multi-million-dollar climate programmes.

Applicants are advised to consult the official AfDB portal and national authorities early in the process.

Grant Overview

The Climate Action Window (CAW) was established under the ADF-16 replenishment cycle of the African Development Bank Group.

It was introduced in response to evidence that most African countries face a widening climate finance gap and struggle to scale climate programmes due to limited concessional funding.

Unlike small project grants, the CAW is structured to finance transformational programmes. These are initiatives that combine infrastructure, policy reform, and institutional strengthening within a single framework.

Purpose of the grant

The grant supports projects that:

• Advance Nationally Determined Contributions (NDCs)
• Support Long-Term Low-Emission Development Strategies (LTSs)
• Strengthen climate resilience in key sectors
• Promote low-carbon growth
• Improve institutional readiness for climate finance

Broad objectives

The Climate Action Window aims to:

• Increase access to climate-resilient infrastructure
• Reduce vulnerability to droughts, floods, and heat stress
• Expand renewable energy and low-carbon transport
• Mobilise co-financing from public and private sources
• Integrate gender and social inclusion into climate programmes

Expert insight on competitiveness

In practice, AfDB favours programmes that combine physical investment (such as infrastructure or systems) with policy or institutional reform.

Standalone equipment purchases or short-term pilots are less competitive than programmes that link infrastructure with governance, financing, or long-term service delivery.

• Meeting eligibility criteria does not guarantee funding.
