Adopting a holistic and multidisciplinary approach, this expertly crafted book comprehensively maps out the complex multi-jurisdictional legal landscape pertaining to the EU’s circular energy system. Offering in-depth critical analysis, it identifies several areas of law and policy that require further scholarly inquiry to ensure the creation of an effective policy framework which can facilitate the move from a linear to a circular energy system. In three thematic sections, the expert contributors first examine the interactions between EU law and policy for waste, agriculture, food and forestry. Focus is then drawn to how, when, and by whom the energy sources created from biowaste can become part of the EU’s energy mix. A range of legal instruments that impact the financing of the circular energy system through taxation, EU financing, and state aid are also considered. The book concludes by reflecting on inefficiencies and ineffectiveness caused by these interactions of legal and policy areas related to the circular energy system.
