The principal objective is to contain, prevent and thereby reduce emissions of f-gases covered by the Kyoto Protocol. This Regulation will make a significant contribution towards the European Community's Kyoto Protocol target by introducing cost-effective mitigation measures and to prevent distortion of the internal market. The main focus is on containment and recovery of f-gases, together with harmonised restrictions on the marketing and use of f-gases in applications where containment of f-gases is difficult to achieve or the use of f-gases is considered inappropriate and suitable alternatives exist.
