As previously investigated in APEC report on co-benefit of renewable energy (RE) and energy efficiency (EE), low carbon (or more aggressively carbon neutrality) is among top key success factor to support two main energy goals of APEC, namely 45% energy intensity reduction by 2035 and doubling the share of RE by 2030. Even though APEC has launched ‘Carbon Neutral’ effort since 2008 followed by Low Carbon Model Towns Task Force (LCMT-TF) in 2010, only 7 out of 21 economies (Canada; Chile People's Republic of China; Japan; Republic of Korea; New Zealand; and the United States) has policy implication at various stages; whereas, other economies may face difficulties in limited resources, lack of experiences and experts. In line with APEC 2022 priority on ‘Sustainable and Inclusive Growth’ through Bio-Circular-Green (BCG) Economy Principle, this project aims to extract lesson learned, best practices and low-carbon technology foresight from those economies with established carbon neutral policy, through documentation studies and interactive workshop, to help accelerate carbon neutral policy dialogue in the rest of economies, which would altogether help achieve APEC RE&EE goals, as well as APEC contribution to global climate action.
