Abstract
This study focuses the accomplishment of global greenhouse gas (GHG) emissions reduction target - 50% reduction of GHG emissions from 1990 levels by 2050 - in Southeast Asia, such as Indonesia, Malaysia, Thailand and Vietnam. This study especially focuses on the required emissions reduction amount in each target country compared with business as usual (BaU) cases. Additionally, the energy system changes caused by the emissions reduction measures are quantitatively analyzed by a computable general equilibrium model.
From the results, approximately 50% to 90% emissions reductions are required compared with BaU cases in the target countries; especially Malaysia and Thailand face high emissions reduction requirements. Achieving the emissions reduction targets causes significant changes of energy system; at least more than the half of the total primary energy supply will be from so called low carbon energies such as renewable energies and nuclear power. Especially in Indonesia, nearly 70% of the total primary energy supply will be from low carbon energies.
