In Indonesia, the usage of cooling – such as refrigeration and air conditioning (RAC) – increases by 15% per year in the industrial, commercial, and private sectors. The use of inefficient appliances with outdated technology is common in these sectors. The project aims to establish a Nationally Appropriate Mitigation Action (NAMA) for industrial and commercial refrigeration and air-conditioning systems, thereby making a significant contribution to meeting Indonesia’s GHG emissions reduction targets.
