Strategy elements for a sustainable bioenergy policy based on scenarios and systems modeling: Germany as example

Bioenergy is an important renewable energy carrier with uncertainties in future development due to sustainability issues. Its further development requires a robust bioenergy strategy on a national level. To provide these strategy elements, we developed a dedicated approach, which includes a new modeling framework, an impact assessment and stakeholder involvement. Demonstrating the approach on the example of Germany, four bioenergy utilization scenarios for a period up to 2050 have been assessed using seven indicators that cover aspects from local infrastructure to global food security. The devised strategy elements address the national and international feedstock supply, promising fields of utilization and appropriate frame conditions. The results coherently address a wide range of policy fields, something which has not been possible in the past.
