Since the objectives of this Directive, namely to achieve the Union's energy efficiency targets of 20 % by 2020 and of at least 32,5 % by 2030 and to pave the way towards further energy efficiency improvements beyond those dates, cannot be sufficiently achieved by the Member States 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.
