Isobutane (R600A) and propane (R290) are far less harmful to the environment than conventional hydrofluorocarbons (HFC) and are already being used in air-source heat pumps. Propane may be the most suitable for high temperature heat pumps. Ammonia (R717) and carbon dioxide also have a low GWP. As of 2023 smaller CO
