Since the objectives of this Directive, namely on the one hand, to prevent any impact from packaging and packaging waste on the environment or to reduce such impact, thereby providing a high level of environmental protection, and, on the other, to ensure the functioning of the internal market and to avoid obstacles to trade and distortion and restriction of competition within the Union, cannot be sufficiently achieved by the Member States, but can rather, by reason of the scale and effects of the measures, 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.
