ASEAN Catalytic Green Finance Facility (ACGF)

The ACGF is an ASEAN Infrastructure Fund initiative supporting governments in Southeast Asia to prepare and finance infrastructure projects that promote environmental sustainability and contribute to climate change goals. The ACGF is owned by ASEAN governments and ADB and managed by ADB.

ACGF: Projects

Since 2019, all ASEAN Infrastructure Fund (AIF) commitments to new investments have been channeled through the ACGF, following its lending modalities and terms, and meeting its criteria for green impact, bankability, and private sector mobilization. With the ACGF’s growing pipeline and portfolio, impact is maximized by allocating a smaller amount of AIF funds into each project to leverage a larger amount of funding from ADB and partner resources.

Investment Principles and Eligibility Criteria

All ACGF projects must meet the ACGF investment principles and eligibility criteria. The criteria were developed jointly by the governments of ASEAN member states and ACGF cofinancing partners and align with the ADB Green Bond Framework and the ASEAN Green Bond Standards. As such they were approved by the AIF Board in November 2019 with the aim to support projects that help meet climate change and environmental goals (green impact), are financially sustainable (bankable), and are designed to mobilize private, institutional, and commercial (PIC) capital in the long term.

ACGF criteria for green impact, bankability, and private sector mobilization

  • Green impact
    Green impact

    Classification as "green" or "priority green" projects, with every project (i) meeting a minimum threshold for climate finance, (ii) demonstrating GHG reduction and climate resilience, and (iii) demonstrating contribution to other environmental benefits.

  • Bankability

    Potential for support to improve financial viability and/or sustainability and bankability.

  • Private capital catalyzation
    Private capital catalyzation

    Potential to catalyze or have a roadmap in place to catalyze at least 10% resources from private, institutional and commercial sources at any time over the first 8 years.

Relevant Sectors and Project Types

The ACGF will support green infrastructure development in the energy, transport, water, and urban sectors, as well as multisector projects that actively contribute to environmental sustainability and climate goals as described above. Examples of green infrastructure include, but are not limited to, renewable energy, energy efficiency, sustainable transport systems, green cities, and sustainable water supply and sanitation.

Lending Modalities and Terms

The ACGF offers attractive lending terms, complementing ADB and partner resources, through two modalities: An ACGF Regular lending modality, open for all AIF borrowing member countries, and an ACGF Concessional lending modality, open for ADB Group A (concessional assistance-only) developing member countries. To help incentivize green infrastructure investments, the ACGF provides low lending rates for the initial years of the project cycle. This two-tier pricing system will partially offset the high upfront capital costs that green infrastructure projects often face, thereby helping to de-risk the projects.
