The Montreal Protocol was designed to protect the stratospheric ozone layer by enabling reductions in the abundance of ozone-depleting substances such as chlorofluorocarbons (CFCs) in the atmosphere. The reduction in the atmospheric concentration of trichlorofluoromethane (CFC-11) has made the second-largest contribution to the decline in the total atmospheric concentration of ozone-depleting chlorine since the 1990s.
This report summarises the data reported by undertakings in accordance with the ODS Regulation for 2015 and looks at the major trends since 2006. Aggregated data reported by companies on the import, export, production, destruction, and feedstock and process agent use of ozone-depleting substances in the European Union.
Hydrofluorocarbons (HFCs) are often used as substitutes for ozone-depleting substances (ODSs) in various sectors, including refrigeration, air-conditioning, aerosols, fire extinguishers, and foam blowing.
