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.
The year 1980 has often been used as a benchmark for the return of Antarctic ozone to conditions assumed to be unaffected by emissions of ozone depleting substances (ODSs), implying that anthropogenic ozone depletion in Antarctica started around 1980. Here, the extent of anthropogenically-driven Antarctic ozone depletion prior to 1980 is examined using output from transient Chemistry-Climate Model (CCM) simulations from 1960 to 2000 with prescribed changes of ozone depleting substance concentrations in conjunction with observations.
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.
The State of the Climate report series is the authoritative annual summary of the global climate. Published in the Bulletin of the American Meteorological Society, the report is edited by scientists at NOAA’s National Centers for Environmental Information.
