Recital 12 Subsidiarity and proportionality

Since the objectives of this Directive cannot be sufficiently achieved by the Member States as they entail the harmonisation of requirements already contained in Directives but can rather, by reason of the scale and effects of the action, be better achieved at Union level, the Union may adopt measures, in accordance with the principle of subsidiarity as set out in Article 5 of the Treaty on European Union. 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.
