ACGF newsletter highlights building investment-ready green infrastructure

ACGF released its January–June 2026 Newsletter, Beyond Financing: Building Investment-Ready Projects, highlighting how strong project preparation, technical expertise, and partnerships can help move green infrastructure toward investment readiness. The edition features progress on the ASEAN Power Grid through the Regional Connectivity Fund, new energy initiatives in Cambodia, insights on scaling climate finance and mobilizing private capital, and key ACGF highlights from the first half of 2026.

Energy Efficiency Revolving Fund launched in Cambodia

With support from ACGF, the $20 million Energy Efficiency Revolving Fund was launched to help small and medium-sized enterprises in Cambodia invest in energy-saving technologies, reduce costs, and improve access to green finance. Supported by the Green Climate Fund and the UK’s Foreign, Commonwealth, and Development Office, the fund will help reduce lending risks and enable more local businesses, including women-owned and women-led enterprises, to adopt practical energy efficiency solutions.

Strengthening Indonesia’s Municipal Bond Market for Sustainable Cities

ADB, with support from ADBI, organized a study visit to Japan for senior Indonesian officials to strengthen knowledge on municipal bond development and sustainable urban finance. The program combined technical discussions with field visits to climate-resilient and disaster prevention project sites in Tokyo, Kawasaki, and Nagoya. Participants gained exposure to municipal bond structures, regulatory processes, project pipeline development, credit ratings, investor demand, and risk management. The study visit formed part of ACGF’s GSS+ initiative to help ASEAN member states mobilize green, social, and sustainable finance, with support from the Green Climate Fund and the United Kingdom’s Foreign, Commonwealth and Development Office.

Strengthening Thailand's Sustainable Finance Market

Through ACGF and its GSS+ initiative, ADB supported Government Savings Bank (GSB) in developing its Sustainable Finance Framework, helping position it among the first state-owned banks aligned with the Thailand Taxonomy. The framework supported GSB's inaugural THB20 billion sustainability bond, which highlighted growing investor confidence in Thailand's green transition priorities. Since 2020, GSS+ has supported more than 20 sustainable finance issuances in Thailand, raising nearly $5 billion across sovereign, state-owned enterprise, and private sector issuers.

Coastal and Port Engineering: Building Lines of Defense

ACGF convened the eighth session of the green ports webinar series on Coastal and Port Engineering: Building Lines of Defense, hosted through ADB's Southeast Asia Development Solutions and Development Asia platforms. The session explored how nature-based solutions, hybrid infrastructure, and adaptive engineering approaches supported ports in managing rising seas, stronger storms, and changing coastal conditions, while drawing on global case studies on living shorelines, eco-engineered defenses, and the beneficial reuse of dredged material.
