When selecting a refrigerant with a lower GWP, consider options like hydrofluoroolefins (HFOs), hydrofluorocarbons (HFCs), and natural refrigerants like carbon dioxide, ammonia, or hydrocarbons. Evaluate the refrigerant’s GWP, ozone depletion potential (ODP), and atmospheric lifetime to ensure it meets your environmental sustainability goals. Consult with industry experts and review relevant regulations, such as the European Union’s F-Gas Regulation, to make an informed decision.
