L 318/28 Official Journal of the European Union 5.11.2014 DECISIONS COMMISSION IMPLEMENTING DECISION of 31 October 2014 determining, pursuant to Regulation (EU) No 517/2014 of the European Parliament and of the Council on fluorinated greenhouse gases, reference values for the period 1 January 2015 to 31 December 2017 for each producer or importer who has reported placing on the market hydro- fluorocarbons under Regulation (EC) No 842/2006 of the European Parliament and of the Council (notified under document C(2014) 7920) (Only the Bulgarian, Czech, Croatian, Dutch, English, Estonian, French, German, Greek, Hungarian, Italian, Latvian, Maltese, Polish, Portuguese, Romanian, Slovakian, Slovenian, and Spanish texts are authentic) (2014/774[EU) THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Regulation (EU) No 517/2014 of the European Parliament and of the Council of 16 April 2014 on fluorinated greenhouse gases ('), and in particular Article 16(1) thereof, Whereas: (1) In accordance with Regulation (EU) No 517/2014, the placing on the Union market of at least 100 tonnes of CO, equivalent of hydrofluorocarbons by producers or importers is subject to quantitative limits in order to ensure their gradual reduction. (2)  The Commission is required to determine those quantitative limits and allocate quotas to each producer or importer. (3)  For the period 2015 to 2017, the quota allocation for producers and importers who reported data under Article 6 of Regulation (EC) No 842/2006 of the European Parliament and of the Council (%) should be deter- mined on the basis of individual reference values. (4)  The reference values are calculated on the basis of the annual average of the quantities of hydrofluorocarbons the producers or importers have reported to have placed on the market from 2009 to 2012, while excluding quanti- ties of hydrofluorocarbons for the usage referred to in Article 15(2) of Regulation (EU) No 517/2014 during the same period, on the basis of available data. (5)  The determination of the reference value is limited by the constraints of the reported data under Article 6 of Regulation (EC) No 842/2006. (6)  The calculation of reference values on the basis of reported data resulted in negative quantities for some undertak- ings. These undertakings are therefore considered to not having reported placing hydrofluorocarbons on the market from 2009 to 2012. They may obtain a quota in accordance with Article 16(2) of Regulation (EU) No 517/2014. (7)  The reference values for producers and importers should be recalculated every three years as from 2017 in order to ensure that undertakings are allowed to continue their activities on the basis of the average volumes they placed on the market in immediately preceding years. This Decision should therefore expire on 31 December 2017. () OJL150,20.5.2014, p. 195.
