Hydrofluorocarbons (HFCs) have been widely used as substitutes for ozone-depleting substances—for example, hydrochlorofluorocarbons (HCFCs) and chlorofluorocarbons (CFCs). Though HFCs have no impact on the ozone layer, they are also long-lived potent greenhouse gases with global warming potentials as high as CFCs, meaning HFCs are regulated by both the Montreal Protocol as well as the Kyoto Protocol. China is a major consumer of HFCs around the world. How to estimate HFC emissions as accurately as possible is therefore a key issue to understand regional contributions, especially for potential emission source areas.
