Production and consumption of ozone-depleting substances in Europe Ozone-depleting substances (ODS) are long-lived chemicals that contain chlorine and/or bromine and can deplete the stratospheric ozone layer. This indicator quantifies the current state of the ozone layer, the progress being made towards meeting the EU’s Montreal Protocol commitments and trends in the remaining uses of ODS within the EU. Context: the ozone layer refers to a region of the Earth’s atmosphere (the stratosphere) in which ozone ( O 3 ) is present in concentrations high enough to absorb most of the sun's ultraviolet (UV) radiation. This natural phenomenon is essential for life on Earth because UV radiation damages living tissue. Ozone depletion refers to the steady decline in the concentration of ozone in the stratosphere and the decrease in stratospheric ozone in the polar regions during the spring season. This has become widely known as the 'ozone hole'. This phenomenon was first observed during the 1970s, when it was shown that the ozone hole was caused by complex chemical reactions in the atmosphere involving so-called ODS, which are almost exclusively a result of human industrial activity.
Emissions and supply of fluorinated greenhouse gases in Europe This indicator tracks trends since 1990 in anthropogenic emissions of the F-gases listed below. The indicator also tracks trends since 2007 in the supply of F-gases. Furthermore, figures for the shares of major intended applications of EU supply are given for the latest available reporting year. EU supply is a parameter derived from company reporting under the F-gas Regulation, which provides information on the actual use of F-gases by EU industries. It focuses on potentially emission-relevant supplies of gases to EU industries and thus does not cover supplies intended for feedstock use or destruction. The lists of gases covered in the supply part of the indicator differ between the period 2007-2013 and the period starting in 2014. For the period 2007-2013, data on only supply in bulk are available. (The term 'bulk' refers to shipments of gases contained in gas containers of all sizes, ranging from large ISO containers of several tonnes to small gas bottles of a few grams.) Since 2014, supply within products and equipment has been recorded. Both of these add up to total EU supply. Bulk supply is calculated by first adding reported amounts for: production bulk imports reclamation stocks from own production or imports held on 1 January of the reporting year and then subtracting the following reported amounts: bulk exports amounts used as feedstock amounts imported for destruction amounts from own production sent for destruction before sales stocks from own production or imports held on 31 December of the reporting year. Gas supplies in products and equipment are the gas contents of products and equipment imported and placed on the EU market. Lists of gases  All gases listed have been tracked for emissions since 1990. Gases in bold have not been tracked for supply in all years since 2007. Gases outside the scope of tracking supply for only the period 2007-2013 are given in italics. Hydrofluorocarbons (HFCs) Perfluorocarbons (PFCs) Other perfluorinated gases HFC-23 PFC-14 (CF4) SF 6 HFC-32 PFC-116 (C2F6) NF 3 HFC-41 PFC-218 (C3F8)   HFC-43-10mee PFC-3-1-10 (C4F10)   HFC-125 PFC-318 (c-C4F8)   HFC-134 PFC-4-1-12 (C5F12)   HFC-134a PFC-5-1-14 (C6F14)   HFC-143 PFC-9-1-18 (C10F18)   HFC-143a PFC-216 (c-C3F6)   HFC-152     HFC-152a     HFC-161     HFC-227ea     HFC-236cb     HFC-236ea     HFC-236fa     HFC-245ca     HFC-245fa     HFC-365mfc     Where the abovementioned gases are used or emitted as part of a mixture of gases, the corresponding proportions are accounted for. For tracking HFC consumption under the Montreal Protocol, only the proportions of HFCs in HFC-containing mixtures are accounted for. HFC-161 is excluded from the scope of the Montreal Protocol.
Production and consumption of ozone-depleting substances ODSs are long-lived chemicals that contain chlorine and/or bromine and can deplete the stratospheric ozone layer. This indicator quantifies the current state of the ozone layer, the progress being made towards meeting the EU’s Montreal Protocol commitments and trends in the remaining uses of ODSs within the EU. Context: the ozone layer refers to a region of the Earth’s atmosphere (the stratosphere) in which ozone ( O 3 ) is present in concentrations high enough to absorb most of the  sun's  ultraviolet ( UV) radiation. This natural phenomenon is essential for life on Earth because UV radiation damages living tissue.

Production, sales and emissions of fluorinated greenhouse gases (F-gases) The indicator tracks trends since 1990 in anthropogenic emissions of the following fluorinated greenhouse gases (F-gases), differentiated by HFCs, PFCs and SF 6 . HFCs PFCs SF6 HFC-23 CF4   HFC-32 C2F6   HFC-41 C3F8   HFC-43-10mee C4F10   HFC-125 c-C4F8   HFC-134 C5F12   HFC-134a C6F14   HFC-152a     HFC-143     HFC-143a     HFC-227ea     HFC-236fa     HFC-245ca     The indicator also tracks trends since 2007 in the aggregated production, bulk imports, bulk exports and consumption of F-gases, differentiated, where available by HFCs, PFCs and SF 6 ; additional F-gases compared to the emissions list are marked in bold. HFCs PFCs SF6 HFC-23 CF4   HFC-32 C2F6   HFC-41 C3F8   HFC-43-10mee C4F10   HFC-125 c-C4F8   HFC-134 C5F12   HFC-134a C6F14   HFC-152a     HFC-143     HFC-143a     HFC-227ea     HFC-236cb     HFC-236ea     HFC-236fa     HFC-245ca     HFC-245fa     HFC-365mfc     ‘Net supply’ is a parameter derived from company reporting under the F-Gas Regulation that provides information on the actual use of (bulk) F-gases by EU industries. Net supply is calculated by firstly adding reported amounts for: production imports (bulk imports only, imports contained in products or equipment are not considered in the reporting under the F-Gas Regulation) stocks held on 1 January of the reporting year ‘other amounts collected for reclamation or destruction from within the EU’, and then subtracting the following reported amounts: exports (bulk exports only, exports contained in products or equipment are not considered in the reporting under the F-Gas Regulation) destruction (on-site by reporting companies and off-site within the EU on reporting companies’ behalf) amounts used as feedstock by reporting companies stocks held on 31 December of the reporting year.   Furthermore, the shares of intended applications of F-gas net supply in the latest available reporting year are given, differentiating between refrigeration and air-conditioning fire protection aerosols foams electrical equipment other, unknown or no information reported.
Production and consumption of ozone depleting substances This indicator quantifies the production and consumption of ozone-depleting substances (ODS) in Europe. ODS are long-lived chemicals that contain chlorine or/and bromine and that destroy the stratospheric ozone layer.
