The Climate Finance Access and Mobilization Strategy for the Member States of the Association of Southeast Asian Nations (2024–2030) provides a comprehensive framework to enhance access to, and mobilization of, climate finance across ASEAN. Developed collaboratively by Brunei Darussalam, the Philippines, and the ASEAN Secretariat with support from the UNFCCC Regional Collaboration Centre, the strategy aims to bridge the significant finance gap needed to address climate mitigation, adaptation, and loss and damage priorities in the region. It outlines six strategic areas of action: developing project pipelines, fostering financial innovation, improving access to international funding, harmonizing regional policies, strengthening capacity-building, and ensuring transparency and accountability in finance flows. With an estimated regional funding need of USD 422.16 billion by 2030, this strategy emphasizes collaboration, country ownership, and enabling environments to attract investment and accelerate the transition to a resilient, low-carbon ASEAN future.
