Alexandra Gottinger and Maria Proestou have published the article “Policy learning and unlearning towards a transition to a sustainable bioeconomy: The case of Germany” in the Journal of Environmental Management. In this paper they investigated objectives and vision in German bioeconomy policy mixes between 2010 and 2024 through the lenses of policy learning. The authors find a process of policy layering whereby emerging objectives of environmental protection and circularity are added to an overall bioresource-oriented vision of the bioeocnomy policy mixes.
