Sustainable energy development that supports regional economic growth is required to achieve optimal sustainable development for Southeast Asia. With the launch of the ASEAN Economic Community (AEC) in 2015, the region’s energy requirements are expected to increase with resulting economic expansion and integration. According to the 3rd ASEAN Energy Outlook under a business-as-usual scenario, the region’s primary energy consumption will grow at 4.5% per annum from 2007 to 2030, resulting in a corresponding 5.7% growth in CO2 emissions. This is largely due to the escalation of carbon-intensive fossil fuels such as coal, as well as oil and natural gas consumption.
