Southeast Asian countries are facing the dual challenge of meeting energy demands and achieving carbon neutrality. The United States plays a crucial role in supporting the region's energy transition plans. By engaging in partnerships with countries like Indonesia, efforts such as the Just Energy Transition Partnership (JETP) are being implemented to catalyze investments in renewable energy. Indonesia's Comprehensive Investment and Policy Plan (CIPP) sets ambitious targets for decarbonization and renewable energy deployment, with significant financial commitments from international groups. However, there are concerns about funding gaps and the exclusion of some emissions sources from Indonesia's targets. The U.S. has the opportunity to enhance cooperation, promote emerging technologies, and drive sustainable energy infrastructure development in Southeast Asia. Collaboration and support for these nations are essential to bridge the gap between energy aspirations and practical implementation while aligning with global climate goals.
