This policy brief examines how Green Public Procurement (GPP) can accelerate the transition toward high-efficiency room air conditioners across ASEAN. It highlights the region’s rapidly growing cooling demand, the availability of efficient inverter technologies, and the potential for stronger procurement criteria to reduce electricity use, emissions, and long-term costs.

It also assesses ASEAN Member States’ readiness for GPP and recommends stronger efficiency thresholds, wider use of life-cycle costing, integration of energy-performance data into e-procurement systems, better inter-agency coordination, capacity building, and harmonised regional GPP guidelines for room air conditioners.
