This conference brought officials from ASEAN and international expertise together to discuss and exchange knowledge, opportunities, challenges and best practices on transitioning from fossil-fuel dependency development pattern, resulting to climate change problem, to cleaner renewable energy enhancement. The cleaner-energy-based development pattern will lead to low-carbon society including crucial steps for collaborative actions for cleaner technology and infrastructure investment for renewable-energy related adaptation on climate change.  As the host of the conference, Thailand conducted another crucial role as chair of ASEAN in 2019 in order to disseminate Thailand’s low-carbon implementations and greenhouse gas emission reduction policies to ASEAN member states. These will jointly enhance the “theme” under Thailand’s position of ASEAN chair through the topic named “Advancing Partnership for Sustainability” on environment.
