5. In addition to the measures provided for by this Regulation, Member States shall, in line with the overall objectives of the Union’s waste policy and in order to reach the targets set out in this Article, implement measures that aim to prevent the generation of packaging waste and to minimise the environmental impact of packaging. Such measures may include the use of economic instruments and other measures to provide incentives for the application of the waste hierarchy, such as the measures referred to in Annexes IV and IVa to Directive 2008/98/EC, or other appropriate instruments and measures, including incentives provided through extended producer responsibility schemes, and obligations on producers or producer responsibility organisations to adopt waste prevention plans. The measures shall be proportionate and non-discriminatory and be designed so as to avoid barriers to trade or distortions of competition. Such measures shall not lead to a shift to lighter packaging material being used to fulfil the goal of packaging waste reduction.
