Abstract

The energy sector in the selected Greater Mekong Subregion (GMS) countries, namely Cambodia, Lao PDR, Thailand, and Vietnam, was responsible for around 84% of total CO2 emissions (equivalent to 423.16 MtCO2) in 2015. Without the intervention of climate change mitigation actions, the emissions of CO2 from energy systems would be tremendously increased. Nevertheless, only Thailand appears to have clear targets for reaching carbon neutrality by the mid-21st century. This study investigates the possibility of energy system transformation to reach net-zero CO2 emissions in 2050 in the selected nations. The Net-Zero- Emission (NZE) scenario is built as a CO2 mitigation countermeasure to the reference scenario. Results show that to reach the goal of decarbonized energy systems in the NZE scenario, efficient and advanced technologies must be used on both the demand and supply sides to reduce around 41% of the final energy demand, and at least 81% of all electricity must be generated by renewable energy. Additionally, the application of advanced low-carbon technologies, including carbon capture and storage in the coal, natural gas, and bioenergy industries and power generation in cooperation with the utilization of electric vehicles in the transport sector, are the key measures for attaining carbon neutrality.
