(68)Labelling of biobased plastic content in packaging should also not be mandatory as there are a number of conditions that biobased plastics have to meet to ensure sustainability and more scientific evidence is necessary to ensure that, over their whole life-cycle, the use of biobased plastic is in line with the principles of circular economy, set out in the communication of the Commission of 30 November 2022 on a Union policy framework on biobased, biodegradable and compostable plastic. However, manufacturers might wish to display that information on their packaging to inform consumers of the biobased plastic content in the packaging. To ensure that such information is communicated in a harmonised manner across the Union, a label to indicate the biobased plastic content should be harmonised.
