Fossil independence and substantial reductions in CO2 emissions seem to be possible with 2nd generation biofuels. New technologies allow a full carbon-to-fuel conversion of non-edible plant parts such as straw or wood, and the cultivation of algae or salt-resistant plants uncouples bioenergy from food production. Nevertheless, impacts on biodiversity, global land and water use are widely unclear and their competitiveness with 1st generation biofuels and electric mobility is an open question. An interdisciplinary team of Empa, University of Zurich and the Wuppertal Institute of Climate, Environment and Energy evaluated the most sustainable production techniques and assessed their potential for our future mobility.
This study aims to investigate whether, to what extent and how a transition toward integrated flood management has taken place in the Dongting Lake area at the middle Yangtze. Accordingly, we conducted a longitudinal research of its flood management (1949–2009). We developed an analytical framework linking regime components to two societal learning types (double and triple-loop learning) that are key to a regime transition. Our study shows that the transition toward integrated flood management has already started, but the whole regime transformation will still take time to complete, due to, for example, the not-yet-ready decision-making processes that shape the structure changes as well as the incompatibilities between what is on paper and real implementation. To understand how the regime transition took place, we investigated where and how triple-loop learning was initiated as well as how so-called "informal learning processes" has contributed to the transition of Dongting flood management.
For decades, the Chinese government has been searching for solutions to cope with the increasing imbalance between the supply and demand of water in the Yellow River Basin. This paper aims at a better understanding of the development of the water allocation regime in the Yellow River Basin between 1950 and 2009, introducing a fresh perspective based on the notion of "regime transition". Accordingly, we investigated 1) whether so-called "Windows of Opportunity for Transition (WOPTs)" emerged, triggering a transition, and whether WOPT(s) resulted in a stable transition towards the new regime; 2) how informal learning processes and epistemic communities have contributed to the regime change. We adapted Kingdon's "multiple stream model" and identified four WOPTs from the 1950s, analyzing the reconfiguration process of the regime after the onset of the transition. Our examples of two types of informal learning processes demonstrate their contribution to the creation of WOPTs and the reconfiguration of the regime. Furthermore, this study indicates, in a qualitative manner, how epistemic communities contribute to the knowledge base of the regime, and thus to its development. Finally, we have provided a general insight into the further development of the water allocation regime and highlighted potential avenues for further studies.
To achieve an efficient use and allocation of limited water resources and thus resolve increasing water use conflicts due to fast rising societal water demands, in 2000, the Chinese government started a management strategy of 'Construction of a Water Saving Society (WSS)'. It is guided by the principle that socio-economic development should consider the carrying capacity of the ecosystem and focuses on institutional innovation, building on the water rights concept. This paper explores the innovation process during the transition towards WSS by investigating the development course of the innovation process during the transition towards WSS, and the adaptive capacity of the existing water management regime underlying the innovation process. Accordingly, an analysis framework consisting of three types of governance activities and factors determining a regime's adaptive capacity was developed, based on the theory of transition management and adaptive governance. The Tianjin and Zhangye WSS experiments were selected for a deep understanding of local innovations. It is revealed that co-evolution of all three types of governance activities that are claimed to be essential for transition has taken place. However, the current adaptive capacity of the regime still needs further enhancement to support the transition towards the desired WSS in China. Finally, some general insights are provided for policy innovations in other political economies.
In the past few decades, geochemically scarce metals have
become increasingly relevant for emerging technologies in
domains such as energy supply and storage, information and
communication, lighting or transportation, which are regarded as
cornerstones in the transition towards a sustainable post-fossil
society. Accordingly, the supply risks of scarce metals and possible
interventions towards their more sustainable use have been
subject to an intense debate in recent studies. In this article, we
integrate proposed intervention options into a generic life cycle
framework, taking into account issues related to knowledge
provision and to the institutional setting. As a result, we obtain
a landscape of intervention fields that will have to be further
specified to more specific intervention profiles for scarce metals
or metals families. The envisioned profiles are expected to have
the potential to reduce action contingency and to contribute to
meeting the sustainability claims often associated with emerging
technol ogies.
Measuring progress towards sustainable development requires appropriate frameworks and databases. The System of Environmental-Economic Accounts (SEEA) is undergoing continuous refinement with these objectives in mind. In SEEA, there is a need for databases to encompass the global dimension of societal metabolism. In this paper, we focus on the latest effort to construct a global multi-regional input-output database (EXIOBASE) with a focus on environmentally relevant activities. The database and its broader analytical framework allows for the as yet most detailed insight into the production-related impacts and "footprints" of our consumption. We explore the methods used to arrive at the database, and some key relationships extracted from the database.
The material stocks in the anthroposphere are growing faster than ever due to urbanization and growing per capita use. Owing to the growing potential insecurity of raw material supply the evaluation of resources gains increasing attention. Despite growing utilization of anthropogenic deposits, ‘urban mining’ has not yet sufficiently been supported by specific exploration methods. An exploration method for anthropogenic deposits is proposed and described by application to the copper stocks of Switzerland. The method combines material flow analysis with a bottom‐up analysis of material stocks. The stock composition and temporal characteristics are analysed by surveys and literature analysis. The stock amounts to 269±31 kg capita -1 for the year 2000. The retrospective data are used as parameters to construct a dynamic stock model, which is calibrated by historical trade statistics. The potential for drafting scenarios is discussed. The stock situation in Switzerland is reviewed and compared with that of other regions.
The current utilisation of natural resources in Germany and Europe is not sustainable, as inter alia stated by the German government as well as by the European Commission. At the same time, increased resource efficiency could lead to various environmental but also economic benefits. This brief study commissioned by Changing Markets presents developments in the field of resource efficiency policies, analyses the status quo of resource consumption with a special focus on fast moving consumer goods and describes potential effects of resource conservations.
The European Waste Framework Directive has defined waste prevention as top of the waste hierarchy meaning nothing less than a fundamental change of the sociotechnical system of waste infrastructures with all its economic, legal, social and cultural elements. Based on an empirical analysis of more than 300 waste prevention measures this paper assesses which prevention effects can realistically be achieved by applying the measures described in the German waste prevention programme or in those of other EU member states. Taking into account waste streams like packaging, food waste, bulky waste and production waste the results show that waste generation is not an unavoidable evil but can be significantly reduced at current level of technology.
The transition towards a circular economy is high on the political agenda and support for innovative business models can be seen as one of the key strategies for its implementation. Nevertheless most of these business models rely on an increasing generation of waste and thus undermine the prevention of waste as top of the waste hierarchy. The paper aims to link this debate to more systemic eco-innovations that offer economic market potentials by reduced material inputs and waste generation. This directs the attention to sufficiency strategies that surpass the level of individual consumer choices and regards the potentials of entrepreneurial sufficiency strategies. It takes the example of waste contracting modelsin Germany as a possible approach of resource-light business models that provide existing utility aspects with altered consumption patterns and decreased resource consumption. It describes environmental and economic benefits and draws conclusions on necessary policy framework conditions.
Ziel dieser Studie ist es, einen aktuellen Überblick über den Stand der Recyclingwirtschaft in Deutschland zu geben. Der Fokus liegt dabei vor allem auf den Marktprozessen, die bereits heute ökonomische Anreize zur Schließung von Stoffkreisläufen geben, bzw. auf spezifischen Hemmnissen, die genau solchen Entwicklungen im Wege stehen.
Aufbauend auf der Analyse spezifischer Hemmnisse für einzelne Abfallfraktionen (rechtliche und institutionelle Hemmnisse, Marktmacht, Informationsdefizite etc.) leitet die Studie verschiedene Instrumente und handlungsorientierte Ansätze ab, die zu einer Verbesserung der Kreislaufführung beitragen könnten; dabei kann Deutschland auch von bestehenden Best-Practice-Ansätzen im Ausland profitieren. Dazu gehören unter anderem der verstärkte Einsatz ökonomischer Instrumente, Maßnahmen zur verstärkten Integration von Abfallwirtschaft und Produktionssektor, Urban Mining Konzepte, internationale Vereinbarungen zum Rohstoffrecycling sowie Green Tech Funds.
