Nachhaltigkeit von Biokraftstoffen: Ziele,Probleme und Instrumente

Klimawandel und Versorgungssicherheit bestimmen die Suche nach ?kologisch und ?konomisch nachhaltigen Energietr?gern. Biokraftstoffe scheinen beiden Zielen gleicherma?en gerecht zu werden. Was ist bei der Bewertung der Nachhaltigkeit von Biokraftstoffen zu beachten? Sollte der Staat bei der Bereitstellung eingreifen? Welche wirtschaftspolitischen Instrumente schaffen positive Anreize beim Verbrauch von Biokraftstoffen?

Qualitative research design was employed and action research approach was implemented in this inductive process. (developed by Muilenburg and Berge). In this research, one of the qualitative research approach, the “action research” carried out within the scope of the pattern, a five-phase collaborative coaching model (FCCM) was developed to awareness regarding teaching and learning processes during the course. The process employed authentic learning criteria as critical reflection, preparation, presentation, chat, video, dialogue and facilitation tools. Self-reflection report was used as data collection technique and analysed through thematic analysis.

Langfristige Entwicklung der außeruniversitären Forschungsförderung in Deutschland

Die au?eruniversit?ren Forschungseinrichtungen werden zum Gro?teil aus ?ffentlichen Mitteln von Bund und L?ndern finanziert. Vor dem Hintergrund der gegenw?rtig expansiven Ausgabenpolitik für diesen Bereich werden hier die ?ffentlichen Zuwendungen für die Max-Planck-, Leibniz-, Helmholtz- und Fraunhofer-Gesellschaft einer Langzeitbetrachtung unterzogen. Dabei ist ein deutlicher Rückzug des Bundes aus der Finanzierungsverantwortung zulasten der L?nder festzustellen.     

Environmental Tax in a Green Market

We examine the impact of an emission tax in a green market characterized by consumers’ environmental awareness and competition between firms for both environmental quality and product prices. The unique aspect of this model comes from the assumption that the cost for an increase in quality is fixed. We show that the emission tax improves welfare, thanks to a decline in pollution and despite an accentuation of product differentiation. The higher the marginal environmental damage is, the higher the optimal tax will be. The optimal tax, however, becomes lower than the marginal damage when the market is not too large. Finally, when marginal environmental damage is not too low, the optimal tax leads to a green product monopoly.
