Bridging the Energy Gap in ASEAN: Scaling Green Finance and Carbon Markets for a Sustainable Transition

Fragmented regulations, limited access to green finance, and underdeveloped carbon markets impede ASEAN's clean energytransition. This paper assesses global best practices, including the EU Emissions Trading System (EU ETS), the Carbon BorderAdjustment Mechanism (CBAM), and green bond standards, through comparative policy analysis, evaluating their suitabilityfor ASEAN's context. By examining specific national cases from Indonesia, Singapore, and Thailand, we identify critical opportunities for enhancing institutional capacities, harmonizing regulatory frameworks, and scaling climate-aligned investment. Astrategic roadmap is developed, focusing particularly on carbon pricing mechanisms, blended finance solutions, and digital innovations such as blockchain and artificial intelligence for regional energy market integration. Findings underline the necessityof coordinated regional carbon markets, standardized green finance instruments, and digitally driven transparency tools. Thisintegrated approach offers ASEAN a pragmatic pathway to accelerate its low-carbon transition, ensuring both economic resilience and regional cooperation. Future research is recommended to explore socioeconomic impacts on vulnerable sectors andstrategies for operationalizing regional carbon pricing across ASEAN's diverse political economies.
