This report summarises the findings and results of the project “Implementation and enforcement of EU regulations on fluorinated greenhouse gases (F-gases) and ozone-depleting substances (ODS) in Bulgaria”. The project’s objective was to identify potential for improving the implementation and enforcement of different EU-regulations, e.g. of Regulation (EU) No. 517/2014, in Bulgaria. It focussed on the topics reporting, containment of ODS and F-gases, incentives for ODS destruction, supervision of the market (including internet trade), alternative technologies to F-gases, as well as training and certification contents and procedures addressing alternatives to F-gases. In addition to this final report, three guidance documents have been developed with more detailed information on the supervision of the market, on natural refrigerants, and on the training and certification topic.
