The first (annual) Indonesia Sustainable Energy Week (ISEW) in 2022 marked an important milestone in fostering collaboration between Indonesia and international partners to accelerate the country’s energy transition. Held as a hybrid event in Jakarta and online, ISEW 2022 focused on advancing strategies for a just, clean, and low-carbon energy system, featuring high-level dialogue about Indonesia’s coal exit strategy, policy frameworks, technologies, and investment needed for decarbonisation. The event brought together policymakers, industry representatives, financiers, and civil society to share perspectives and develop comprehensive approaches for energy transition, including technical and policy discussions, stakeholder engagement beyond the energy sector, and strategic communication. ISEW 2022 highlighted the significance of accelerating climate mitigation through a robust energy transition roadmap and investment ecosystem, supporting Indonesia’s commitment to net zero emissions and its Nationally Determined Contribution to the UNFCCC
