(22)Since the objectives of this Directive cannot be sufficiently achieved by the Member States and can therefore, by reason of their scale and their effects, be better achieved at Community level, the Community may adopt measures, in accordance with the principle of subsidiarity as set out in Article 5 of the Treaty. In accordance with the principle of proportionality, as set out in that Article, this Directive does not go beyond what is necessary in order to achieve those objectives.
