Global warming due to greenhouse gas emissions is becoming more serious, with the global average temperature for 2024 reaching an all-time high. The Association of Southeast Asian Nations (ASEAN) is developing the ASEAN Climate Change Strategic Action Plan 2025-2030 (ACCSAP) with the aim of transitioning to a resilient and net-zero society. IGES has been working on a research project funded by the Environment Research and Technology Development Fund 1CN-2206 from 2022 to 2024 and developed a comprehensive framework (macro-frame) consisting of seven principles and seven actions, including social inclusion, on national long-term roadmaps to promote synergistic implementation of mitigation and adaptation in ASEAN and other Asian countries. For a synergistic and inclusive transition for mitigation, adaptation and sustainable development, it is desirable to understand the existence of vulnerable groups in the region and examine their vulnerability and resilience as a starting point with reference to quantitative roadmaps derived from integrated assessment models, and to spread technologies for renewable energy, etc. that have a high synergy effect with resilience promotion measures and adaptation measures in a way that suppresses conflicts with land use and the natural environment, etc. (trade-offs). The principles and actions of the macro-frame should be reflected in climate policies such as the ACCSAP, national long-term strategies (LTS), national contribution targets (NDCs) and national adaptation plans (NAPs), which will trigger the mainstreaming of climate change targets and measures in a synergistic and inclusive manner. This session will introduce key messages from the policy recommendations (guidance) documents and technical reports developed with national and international partner research organisations, and discuss future developments with ASEAN energy policy makers and their respective research organisations.
