Stationary air-conditioning, commercial refrigeration and domestic refrigeration make up 80 percent of India’s installed cooling capacity. Currently 90 percent of India’s cooling capacity and annual refrigeration and air-conditioning (RAC) is based on hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons (HCFC) refrigerants, about 10 percent is based on naturals.

The report, published on 12 October, was prepared by shecco on behalf of the Greens European Parliament political group and shows a marked increase in CO₂ transcritical stores and companies that are working with natural refrigerants.
