This report examines the potential impacts of a growing demand for space cooling, primarily through the use of air conditioners (ACs), in the ten countries of the Association of Southeast Asian Nations (ASEAN): Cambodia, Brunei, Indonesia, Lao People’s Democratic Republic (Lao PDR), Malaysia, Myanmar, Philippines, Singapore, Thailand and Viet Nam. In addition to an analysis of trends and drivers, the report compares two scenarios describing potential increases in energy consumption, peak electricity demand and CO₂ emissions from space cooling across ASEAN countries.
