A policy mix for resource efficiency in the EU : key instruments, challenges and research needs
(2019)
Against the background of an often wasteful use of natural resources, the European Union has made resource efficiency a top policy priority. Policy formulation is, however, at a very early stage in many Member States, with often vague notions of what resource efficiency means, characterised by fragmented instruments and overlapping competencies. This paper develops a conceptual framework for defining, assessing and developing resource efficiency policy mixes. It argues that a mix of policies and instruments is best suited to overcoming the complex challenges of the 21st Century. Such a mix addresses multiple resource domains at a strategic, high level and contains interacting instruments targeting multiple actors, levels of governance and sectors and life-cycle stages of resource use. This paper looks at criteria for effective resource efficiency policy instruments, presents both an indicative policy mix across 9 policy domains and case studies (on environmental harmful subsidies, supply chain efficiency in food systems and product-service systems) and identifies key challenges to overcome trade-offs in instrument design, maximise synergies, reduce conflicts, promote coherence, coordinate activities and move from theory to practice. Research needs are discussed regarding who shall devise, implement, and coordinate such a policy mix, considering negotiating power, timing and complexity.
Research on sustainability transitions has expanded rapidly in the last ten years, diversified in terms of topics and geographical applications, and deepened with respect to theories and methods. This article provides an extensive review and an updated research agenda for the field, classified into nine main themes: understanding transitions; power, agency and politics; governing transitions; civil society, culture and social movements; businesses and industries; transitions in practice and everyday life; geography of transitions; ethical aspects; and methodologies. The review shows that the scope of sustainability transitions research has broadened and connections to established disciplines have grown stronger. At the same time, we see that the grand challenges related to sustainability remain unsolved, calling for continued efforts and an acceleration of ongoing transitions. Transition studies can play a key role in this regard by creating new perspectives, approaches and understanding and helping to move society in the direction of sustainability.
In der Dissertation wird eine Methodik entwickelt, welche die Berechnung des Redispatcheinsatzes im deutschen Übertragungsnetz ermöglicht. Dabei wird die Auswirkungen einer Integration der Flexibilität aus dezentralen Anlagen in das elektrische Energiesystem dargestellt. Durch die Integration von dezentralen Flexibilitäten können geringere Brennstoff- und CO2-Zertifikatskosten bei relativ konstanten CO2-Emissionen erreicht werden. Bei einem Redispatcheinsatz, welcher die Leistungserhöhung aus konventionellen thermischen Kraftwerken weitgehend vermeidet, kann bei der Berücksichtigung dezentraler Flexibilitäten bis zu 99 Prozent der benötigten Redispatcherhöhung aus konventionellen Kraftwerken mit Hilfe dezentraler Alternativen ersetzt werden. Diese Übernahme der Redispatchaufgaben durch dezentrale Anlagen ist allerdings mit einer signifikanten Erhöhung der Redispatchkosten verbunden.
