Description: In the past decades, risk management in the financial community has been dominated by data-intensive statistical methods which rely on short historical time series to estimate future risk. Many observers consider this approach as a contributor to the current financial crisis, as a long period of low volatility gave rise to an illusion of control from the perspectives of both regulators and the regulated. The crucial question is whether there is an alternative. There are voices which claim that there is no reliable way to detect bubbles, and that crashes can be modeled as exogenous "black swans". Others claim that "dragon kings", or crashes which result from endogenous dynamics, can be understood and therefore be predicted, at least in principle. The authors suggest that the concept of "Bayesian risk management" may efficiently mobilize the knowledge, comprehension, and experience of experts in order to understand what happens in financial markets.

Description: Both focus group discussions and information-choice questionnaires (ICQs) have previously been used to examine informed public opinions about carbon dioxide capture and storage (CCS). This paper presents an extensive experimental study to systematically examine and compare the quality of opinions created by these two research techniques. Depending on experimental condition, participants either participated in a focus group meeting or completed an ICQ. In both conditions participants received identical factual information about two specific CCS options. After having processed the information, they indicated their overall opinion about each CCS option. The quality of these opinions was determined by looking at three outcome-oriented indicators of opinion quality: consistency, stability, and confidence. Results for all three indicators showed that ICQs yielded higher-quality opinions than focus groups, but also that focus groups did not perform poor in this regard. Implications for the choice between focus group discussions and ICQs are discussed.

Description: Analytical Strategic Environmental Assessment (ANSEA) is an insightful new approach to environmental evaluation, based on decision theory, policy analysis and environmental considerations. These concepts, though not new in their own fields of application, are combined and integrated in an innovative fashion. This book presents recent research on the implementation of the ANSEA approach which aims to ensure environmental values are properly integrated into the decision-making process.

Description: The Wuppertal Institute developed, in the early 1990s, an input-oriented lifecycle-wide resource accounting method, the "Material Input per Service-Unit" concept (MIPS), today also referred to as "Material Footprint". The official handbook applicable to products, services, and processes describes a MS Excel-based sequential approach for calculating MIPS. Today's computing power, available to every researcher, and access to software and databases dedicated to lifecycle analysis make calculating MIPS using matrix inversion possible. This also opens up possibilities for enhancing MIPS-models programmatically: parameterizing the foreground and background systems, batch modeling for producing time series, and computational algorithms enhancing interpretation. The article provides (1) an overview of the methods and tools used for calculating MIPS from its origins to today, and (2) demonstrates some of the programmatically enhanced capabilities offered to MIPS-practitioners.

Description: The paleosols of the Last Interglacial are presented in many loess sequences of the European temperate zone by soils with Argic horizon, that are considered to be the pedological response to the bioclimatic conditions of that period. We studied micromorphological, physical/chemical (bulk chemical composition, texture and dithionite-extractable iron) and mineralogical characteristics of two profiles – an Eemian Luvisol in Upper Austria (Oberlaab) and a Mikulino Albeluvisol in Central Russia (Alexandrov Quarry near Kursk) to compare them with recent analogous soils and to make further paleoecological and chronological inferences. Both profiles showed a set of characteristics indicative for weathering of primary minerals, clay transformation illuviation and surface redoximorphic (stagnic) processes. Paleosols demonstrate more advanced development than the Holocene analogues manifested however in different pedogenetic characteristics. The Eemian Luvisol in Upper Austria is characterized by stronger clay illuviation manifested in higher clay content and abundance of illuvial clay pedofeatures in the Bt horizon. Mikulino Albeluvisol in Central Russia is more strongly affected by eluvial and stagnic processes evidenced by deeper and more intensive accumulation of bleached silty material and clay depletion. We suppose that the properties of parent material are responsible for these differences. Russian Albeluvisol is formed on the Dnepr loess poor in weatherable minerals and having limited capacity for buffering acidity and clay formation. The higher development status of the Last Interglacial paleosols compared to the Holocene soils having however same type pedogenesis implies longer soil formation period, that agree with some of the paleobotanical proxies and could include besides MIS 5e part of MIS 5d; the warmer and moister paleoclimate during MIS 5e could also account for more advanced paleosol development Several phases of clay illuviation interrupted by frost structuring and deformation are detected in the Eemian Bt horizon in Upper Austria. It suppose even longer development that could extend to the Early Würmian interstadials (late substages of MIS5).

Description: A detailed study of a loess-paleosol sequence in Oberlaab, Upper Austria, is presented with emphasis on macro- and micromorphological features, grain size distribution, rock magnetism properties, and weathering degree that allows correlation with other loess-paleosol sequences in neighboring areas, and interpretation of main pedogenic trends. The studied sequence comprises four paleosol complexes, which likely developed during four interglacial stages MIS 11, 9, 7 and 5e, and a modern soil. The oldest paleosol complex (OL5) represents three phases of soil formation, and distinct sedimentary events never reported in the area, with strong reductomorphic properties. The OL4 profile also results from three phases of pedogenesis with increased reductomorphic features in the deepest zone (affected by cryoturbation events). OL3 has abundant features related to gleyic/stagnic processes, but shows signs of clay illuviation. OL2 (Eemian soil) correlates with the MIS 5e. This paleosol shows higher degrees of clay illuviation and weathering, and fewer features related to reductomorphic processes. The modern soil is also polygenetic and constitutes a pedocomplex. Its lowermost part is formed by Würmian glacial deposits, where no well-developed soils are found; only reworked materials and pedosediments. Main pedogenic trends in the sequence are clearly differentiated. All of the paleosols were formed in humid environments, but differing in drainage conditions. The base, with OL5 and OL4 paleosols, was more affected by gleyic processes, while in the upper paleosols, especially OL2, clay illuviation is dominant. We interpret such differences to be caused by the topographic position. The basal paleosols were more affected by fluvioglacial processes due to their position on top of the terrace. The upper paleosols received increased amounts of sediment through fluvial, colluvial and aeolian (loess) input.

Description: The more than 12 m thick loess-paleosol sequence in Paudorf, Lower Austria, has been known for decades as locus typicus of the “Paudorfer Bodenbildung” (Paudorf paleosol). The upper section of the outcrop contains an up to 1 m thick pedocomplex that developed during MIS 5. The differentiated sequence of loess-like sediment below, including a more than 2 m thick pedocomplex in its basal part, is an exceptional archive of landscape evolution from the Middle Pleistocene. Herein we present detailed paleopedological and sedimentological surveys, as well as first micromorphological observations to address the sequence in its entirety and the processes leading to its genesis. Furthermore, high resolution color and carbonate analyses, as well as detailed texture analyses, have resulted in a substantial database. The studies show that the loess sediments were subject to a polygenetic development under periglacial conditions reflected in eolian silt and fine sand accumulation, admixture of local material during (mostly solifluidal) redeposition and in situ processes. Horizons with signs of pedogenesis, particularly the two pedocomplexes, document longer phases of stability; the stages of development can be correlated to equivalent sequences and seen as paleoclimatic signals where chronological data are available. The upper pedocomplex is a Chernozem of the early last glacial (MIS 5c–[a?]), which developed in a solifluidal redeposited (MIS 5d) interglacial Cambisol (MIS 5e). Cryosols, typical for MIS 6 sequences, are present in the loess sediment below. The lower pedocomplex formed during several warm stages of varying intensities, with interruptions caused by colluvial processes and admixture of eolian sediment during colder stages.

Description: This book attempts to outline the history of gold mining and related subjects like marketing, trading and use of gold from the legendary times until today. The work will not limit itself to the borders of present day Ghana but will have to consider also adjacent areas of today's Mali, Burkina Faso, Niger and Nigeria to put especially the earlier historical developments into their proper context. This History will attempt to piece together not only the technical development of gold mining, but the historical, political and socio-economical pressures which caused and were also generated by the development of the gold mining sector within this geographical area. A disadvantage for the historian digging into West African History is the fact that the peoples dwelling in these areas had not developed written records but rather depended on oral tradition of their history. Systematic attempts to preserve this oral history through taping or writing down were undertaken only over the last 100 to 150 years, in sporadic attempts may be a little earlier. The historical events of the last millenium, i.e. from 1000 A.D. to today can be reconstructed for the first half through the written records overcome by the efforts of the muslim scholars, which in a very scientific manner recorded historical, political, economical and social developments in West Africa and in the sub-Sahelian areas. Over the last 500 years the advent of European traders, missionaries and adventurers produced written records of events they encountered during their more or less long ventures at the shores of the West Coast. Of course, a lot of information they gathered and laid down in their records was based on hear-say sources because only very few adventurers penetrated the hinterlands. Nevertheless, we will realise that all these records, as one-sided and biased they might be in many cases, together with oral tradition culled from the traditional rulers and archeological evidence, can form a quite solid basis for the reconstruction of historic events in West Africa in general and the area of today's Ghana in particular. Completely different is the picture for the earlier times, i.e. before 1000 A.D. for the three millenia back to 2000 B.C. We are very certain that negroid ethnics were populating the West African lands but we do not know where they came from, how they called themselves, which political and socio-economic systems they had developed for themselves and whether or when they perished, migrated away or were absorbed by other negroid ethnic groups who themselves migrated from almost uncertain directions into these tropical rainforests. In short, whilst we can speak of the Bono, Gyaman, Guan, Asante for the last millenium, we can only call the previous inhabitants the black "West-African", sometimes differentiated according to distinct cultures named according to the location of their archeological finds, like Ntereso, Nok, Benin etc. These sites prove the existence of highly developed cultural and technical skills expressed in the overcome artefacts found in the excavations. But the curtain in respect of the true nature, descendancy, sociology of these people, who were the originators and perpetuators of these documented cultures, can not be lifted. Here reflection on the flow of historical events from the ancient times to modern times. Guggisberg's citation We will leave it to you, the esteemed reader to form an opinion on the question: Did the development of the gold mining sector benefit the People of Ghana ?

Description: Die vorliegende Arbeit stellt die paläomagnetische Bearbeitung der Mittel- bis Oberpleistozänen Löss-/Paläoboden-Sequenz im Areal der ehemaligen Ziegelei Würzburger in Aschet bei Wels vor. Fünf intensiv entwickelte Paläoböden, bzw. Pedokomplexe wechseln mit dazwischen geschalteten Lößlehmlagen ab. Im Rahmen einer Aufbaggerung konnte ein Profil mit einer Mächtigkeit von über 12 m erschlossen werden. Für die magnetostratigraphischen Laboruntersuchungen im Paläomagnetiklabor der Montanuniversität Leoben wurden insgesamt 587 orientierte Proben entnommen, so dass eine beinahe lückenlose Beprobung vorliegt. Die Proben wurden mit magnetischen Wechselfeldern sowie thermisch abmagnetisiert. Zur Bestimmung der magnetischen Trägerminerale in den Sedimenten wurden Curiepunkt-Bestimmungen durchgeführt, die eine Hauptträgerphase mit einem Curie-Punkt bei ca. 580°C (Magnetit), sowie untergeordnete Anteile von Hämatit mit 670°C Curie-Punkt ergaben. Die magnetischen Parameter zeigen eine Folge von Bereichen mit intensiver Magnetitbildung in den Paläoböden, die dem relativ wärmeren Klima von Interglazialen zugeordnet werden können. Die Mehrzahl der Proben zeigen charakteristische Remanenzrichtungen im Bereich des normalen pleistozänen Erdmagnetfeldes. In einigen Profilabschnitten traten stark abweichende Remanenzrichtungen auf, die auf Exkursionen des Erdmagnetfeldes hinweisen. Die beobachteten Exkursionen im Profil Wels-Aschet werden aufgrund paläopedologischer-pedostratigraphischer Ergebnisse in das Zeitintervall von 570 ka (Emperor - Big Lost - Calabrian Ridge) bis 110 ka (Blake) gestellt. Die Brunhes/Matuyama-Grenze (776 ka) wurde nicht erreicht.

Description: Auf den mittelpleistozänen fluvioglazialen Terrassen der Traun-Enns-Platte in der Region um Wels (Oberösterreich) wurden drei Löss-/Paläobodensequenzen untersucht. Jedes dieser Profile ist für mittelpleistozäne Abfolgen im nordöstlichen Alpenvorland charakteristisch. Die Profile umfassen mächtige Pedokomplexe, welche eine Differenzierung und Einstufung von interglazialen Paläoböden erlauben. Die Löss-/Paläobodensequenz von Oberlaab ist auf der fluvioglazialen Terrasse des Mindel-Glazials im klassischen Sinne entwickelt (Jüngere Deckenschotter) und weist vier interglaziale Paläoböden auf. Diese Tatsache macht eine Einstufung der Jüngeren Deckenschotter mindestens in die fünftletzte Kaltzeit wahrscheinlich (MIS 12). Die Deckschichten auf den Günz-Deckenschottern im klassischen Sinn (Ältere Deckenschotter) beinhalten fünf Paläoböden. Beide Lokalitäten weisen eine sehr intensive Pedogenese in ihrem basalen Pedokomplex auf, die wesentlich ausgeprägter ist, als in den überlagernden Paläoböden. Die pedostratigraphischen Ergebnisse lassen eine Einstufung der Älteren Deckenschotter mindestens ins MIS 16 zu.

Description: Grain size analyses, bulk and clay mineralogical data were used to characterize weathering within the loess-paleosol-sequence of Oberlaab in Upper Austria. Soil horizons can be clearly identified by the calculation of weathering index Kd from granulometric parameters. The mineralogical composition of the bulk samples shows increasing weathering intensity from the top to the bottom. The weakest weathering stage 1 is not present in Oberlaab, because all samples are free of carbonate minerals. Weathering stage 2 can be found in the upper part of the profile, whereas stage 3 is mainly present in the lowermost horizons. The highest weathering stages 4 and 5 are not present in Oberlaab. The clay mineral distribution in the profile is dominated by the disappearance of primary chlorite in the upper part of the profile and the neoformation of vermiculites from illite by pedogenesis in the lower part. Two different types of mixed layer minerals were found in the pedocomplexes. An illite/chlorite mixed layer mineral occurs following the disappearance of chlorite and is present in the Eemian luvisol. The second mixed layer mineral consists of illite/vermiculite and is present in the whole profile. The weathering stages obtained from the clay mineral composition are slightly lower than that of bulk mineralogy, but reach as well stage 3 in the lower part of the profile.

Description: This book provides a guide for transport policymakers and planners on achieving low-carbon land transport systems and describes possible measures for reducing emissions. Based on wide ranging research, case studies from developed and developing countries and an overview of policy scenarios, the book presents a toolbox for decision-makers with a huge variety of measures which can be tailored to their specific circumstances. It also addresses the question of how policies can be bundled successfully and integrated in urban transport decision-making and planning. Practical information is given on how greenhouse gas savings are measured as well as success factors for implementing policies and measures in complex decision-making processes.

Description: The need of recycling obsolete mobile phones has significantly increased with the worldwide propagation of mobile phones and their inherent rapid turnover. In this article, we examine the acceptance of mobile phone return programs by using the Technology Acceptance Model and multiple case studies. Our findings can provide valuable recommendations for the setup of future mobile phone return programs.

Description: Current well-being research often overlooks human dependency on natural resources and undervalues the way environmental impacts affect human activities. This article argues that the capability approach provides an applicable framework for inquiring into ecologically sustainable well-being. Therefore, this pilot study aims to develop a research method for integrating the measurement of natural resource use with capability-based well-being research. Semi-structured interviews were carried out with 18 Finnish minimum income receivers and their natural resource use (material footprints) was measured in five central functionings by using the Material Input Per Unit of Service (MIPS) method. The connections between capabilities, functionings and material footprints are interpreted from a person-centered perspective in order to explain the individual variety in material footprints. The results show that the material footprints of minimum income receivers are smaller than with an average Finn but they still exceed what is estimated to be an ecologically sustainable level of natural resource use.

Description: Resource efficiency in production and technological innovations are inadequate for considerably reducing the current use of natural resources. Both social innovations and a complementary and equally valued strategy of sustainable consumption are required: goods must be used longer, and services that support collaborative consumption (CC) patterns must be extended. "Using rather than owning" strategies, such as product sharing, have the potential to conserve resources. Based on the results of different German studies, this article highlights the resource-saving potentials of CC patterns and recommendations proposed for policies and further research questions. The purpose of this paper is to show that a general resource-saving potential can be realized by "use rather than own" schemes, depending on the application field and the framework for implementation. CC is suitable for making a positive contribution to achieving the Factor 10 target by playing an important role in changing consumer patterns.

Description: This paper argues that the contemporary growth paradigm needs to be reconsidered on a micro level of consumption and product service-systems. This becomes necessary since a dynamic link between macro strategies and micro implementation of sustainable growth is missing up to date. Therefore, mainstream sustainability strategies of efficiency and consistency are extended by sufficiency in order to integrate strategies for individual welfare within their social environment. Limits to and drivers for growth are revised and updated socially in terms of qualitative values, diminishing marginal utility or symbolic social distinction. We elaborate a definition of sustainable growth that fosters individual welfare by enhancing social enactment within the boundaries of environmental space. Shifting focus on social aspects in design fosters more sustainable production and consumption patterns while sustaining individual welfare. We derive latent indications for eco-intelligent product service-arrangements and evaluate to concepts by referring to introduced definitions and according indications. With doing so, we illustrate new pathways for the translation of sustainable growth and strategies into product service-systems.

Description: Improving material efficiency in the manufacturing industry is a sustainability imperative for companies due to economic and environmental advantages such as the reduction of material costs and resource use. Innovative solutions in terms of material efficiency measures are diverse and widespread. As a systematic assessment of efficiency approaches and their effects are likely to support dissemination and deployment, this paper aims to develop an approach that helps to classify material efficiency measures. The classification approach presents different dimensions and properties of material efficiency measures based on a literature analysis regarding existing classification approaches as well as on work that has been conducted for the Eco-Innovation Observatory. The classification has been designed as basis for an empirical impact assessment of material efficiency measures based on a data sample that stems from the German Material Efficiency Agency.

Description: This chapter addresses material leakage as a major problem of international open markets for used goods, in particular for used vehicles. It develops elements of an international metal covenant that should allow for a more sustainable management of global material flows in that area. The arguments in favour of such a proposal are as follows: Any regulation should actively seek for industry participation, taking advantage of business interest in supplying a sufficient amount of materials while lowering materials cost. It should also address public issues such as sustainability of recycling and waste. A first section analyses contracts as a tool to overcome knowledge problems that occur when many actors are involved. A second short section gives empirical evidence for material leakage in the case of used vehicles from Germany. A third section develops elements of an international metal covenant. A fourth section analyses potential impacts and discusses legal and institutional issues. Finally, some conclusions are drawn.

Description: Several studies in Germany aimed at the development of a sound database on existing waste prevention measures by public bodies at the local, regional and federal levels. These results are the starting point for the creation of a national prevention program, which has to be presented by all European Member States until the end of 2013 - due to the revised European Waste Framework Directive. Based on this empirical foundation, this paper draws conclusions with regard to drivers and barriers for eco-innovations in the field of waste prevention. The analysis shows that an optimized adaptation of information on waste prevention to the needs of specific target groups is still missing but could be a relevant driver. With regard to barriers the results of the study show that waste prevention is by no means always a win–win-situation. Institutional frameworks are missing to coordinate the different interests and for the exchange of experiences that could help to realize learning effects regarding innovation approaches.

Description: This article presents the accounts of China's Total Material Requirement (TMR) during 1995–2008, which were compiled under the guidelines of Eurostat (2009) and with the Hidden Flow (HF) coefficients developed by the Wuppertal Institute. Subsequently, comparisons with previous studies are conducted. Using decomposition, we finally examine the influential factors that have changed the TMR of China. The main findings are the following: (1) During 1995–2008 China's TMR increased from 32.7 Gt to 57.0 Gt. Domestic extraction dominated China’s TMR, but a continuous decrease of its shares can be observed. In terms of material types, excavation constituted the biggest component of China's TMR, and a shift from biomass to metallic minerals is apparent; (2) Compared with two previous studies on China's TMR, the amounts of TMR in this study are similar to the others, whereas the amounts of the used part of TMR (Direct Material Input, DMI) are quite different as a result of following different guidelines; (3) Compared with developed countries, China's TMR per capita was much lower, but a continuous increase of this indicator can be observed; (4) Factors of Affluence (A) and Material Intensity (T), respectively, contributed the most to the increase and decrease of TMR, but the overall decrease effect is limited.

Description: The need for recycling obsolete mobile phones has significantly increased with their rapidly growing worldwide production and distribution. Return and recycling rates are quite low; people tend to keep old, unused phones at home instead of returning them for recycling or further use because of a lack of knowledge and acceptance of return programmes. Thus far, individual use and recycling behavior has not shown any trend towards more sustainable patterns. Consequently, an increased awareness is needed for the high environmental and social impact throughout the whole value chain of a mobile phone - there is simply a lack of information and knowledge regarding sustainability issues around the mobile phone. A teaching material was therefore developed in a German research project, based on the concept of the ecological rucksack, presenting comprehensive information about the value chain of a mobile phone. Its application in different schools led to an increased awareness and interest among pupils for the connection between sustainability, resources and mobile phones. Based on these research results, this paper analyses young people’s knowledge of sustainability issues linked to their mobile phones and their acceptance of more sustainable behavioral patterns regarding their mobile, including return and recycling programmes.

Description: Sustainability policy in the early 2000s is based on and therefore influenced by scientific literature on "transition". The importance of this link has inspired the authors to explore the structure of cooperating authors and citation networks in the field. In order to understand "transition" literature, we compare it with an alternative term for change, "transformation", which is also used in the context of socio-technical shifts towards sustainability. We expose the different structures of these fields with an overview of keywords, key references, key authors, and the coherence between references and authors. By analysing co-author and citation networks, we find large differences in these groups of documents. The transition literature is characterised by a large network of directly and indirectly cooperating authors with clear clusters; transformation literature contains smaller author networks. Key transition authors are predominantly Dutch. They repeatedly write together and cite each other's work. The transition literature is tightly knit with high degrees of internal references and a clearly distinguishable core. Transformation literature has fewer connections between authors and articles. The connecting articles, each with many global citations, form its basis. This analysis can be used as a step to continue the debate on the role of transition and transformation literature in sustainability and renewable energy policy. The transformation literature teaches us that older streams of thought are still relevant and may be used as "glue" for linking change with respect to sustainable energy to wider developments. Rediscovering existing literature in new combinations may lead to promising new views on sustainable energy.

Description: The German government aims to obtain at least 40 percent of its electricity from renewable sources by 2030. One of the central steps to reach this target is the construction of deep sea offshore wind farms. The paper presents a material intensity analysis of the offshore wind farms "Alpha Ventus" and "Bard Offshore I" under consideration of the grid connection. An additional onshore scenario is considered for comparison. The results show that offshore wind farms have higher resource consumption than onshore farms. In general, and in respect to the resource use of other energy systems, both can be tagged as resource efficient.

Description: The Durban conference decided to establish a new market-based mechanism that is to cover a broad segment of a country's economy. The implementation details are to be agreed at this year's conference in Qatar. The question is, however, which developing countries would actually be able to implement such a new mechanism. The introduction of the EU emission trading system highlighted the many challenges that even advanced developed countries face when establishing a carbon market. This paper by Wolfgang Sterk and Florian Mersmann therefore aims to explore the essential prerequisites for the implementation of new market mechanisms (NMM). In addition to a theoretical discussion it considers the cases of China and Mexico.

Description: The transport sector is the second largest and one of the fastest growing energy end-use sectors, representing 24% of global energy-related greenhouse gas emissions. The International Energy Agency has developed scenarios for the transport sector within the overall concept of mitigation pathways that would be required to limit global warming to 2 °C. This paper builds on these scenarios and illustrates various passenger travel-related strategies for achieving a 2° transport scenario, in particular looking at how much technology improvement is needed in the light of different changes in travel and modal shares in OECD and non-OECD countries. It finds that an integrated approach using all feasible policy options is likely to deliver the required emission reductions at least cost, and that stronger travel-related measures result in significantly lower technological requirements.

Description: In communication sciences partnerships between entertainment media professionals and sustainability organizations conveying prosocial messages are called "Entertainment-Education (E-E) collaborations". Whereas comprehensive research takes place in countries such as the Netherlands and the US, the field is a terra incognita in Germany. Even though German E-E collaborations are designed and implemented they still are unusual experiments. The qualitative study presents first results on characteristics, conditions and forms of E-E collaborations in Germany's television field since the 1990s. It reveals various factors leading to a highly complex situation for the collaborating partners. One central factor is the media legislation, which does not provide a clear orientation standard for the partners. Another one is the public acceptance of E-E collaborations. Some forms are accepted while others are not. Hence, for German television formats, forms with a low to medium level of collaboration (E-E service and E-E license partnerships) should be preferred in contrast to high level collaboration forms (E-E co-productions and E-E inscript participations).

Description: Only three days after the beginning of the nuclear catastrophe in Fukushima, Japan, on 11 March 2011, the German government ordered 8 of the country's 17 existing nuclear power plants (NPPs) to stop operating within a few days. In summer 2011 the government put forward a law - passed in parliament by a large majority - that calls for a complete nuclear phase-out by the end of 2022. These government actions were in contrast to its initial plans, laid out in fall 2010, to expand the lifetimes of the country's NPPs. The immediate closure of 8 NPPs and the plans for a complete nuclear phase-out within little more than a decade, raised concerns about Germany's ability to secure a stable supply of electricity. Some observers feared power supply shortages, increasing CO2-emissions and a need for Germany to become a net importer of electricity. Now - a little more than a year after the phase-out law entered into force - this paper examines these concerns using (a) recent statistical data on electricity production and demand in the first 15 months after the German government's immediate reaction to the Fukushima accident and (b) reviews the most recent projections and scenarios by different stakeholders on how the German electricity system may develop until 2025, when NPPs will no longer be in operation. The paper finds that Germany has a realistic chance of fully replacing nuclear power with additional renewable electricity generation on an annual basis by 2025 or earlier, provided that several related challenges, e.g. expansion of the grids and provision of balancing power, can be solved successfully. Already in 2012 additional electricity generation from renewable energy sources in combination with a reduced domestic demand for electricity will likely fully compensate for the reduced power generation from the NPPs shut down in March 2011. If current political targets will be realised, Germany neither has to become a net electricity importer, nor will be unable to gradually reduce fossil fuel generated electricity. Whether the reduction in fossil fuel use will be sufficient to adequately contribute to national greenhouse gas mitigation targets significantly depends on an active policy to promote electricity savings, continuous efforts to increase the use of renewables and a higher share of natural gas (preferably used in combined heat and power plants) in fossil fuel power generation.

Description: The 2011 Japanese earthquake and tsunami, and the consequent accident at the Fukushima nuclear power plant, have had consequences far beyond Japan itself. Reactions to the accident in three major economies Japan, the UK, and Germany, all of whom were committed to relatively ambitious climate change targets prior to the accident are examined. In Japan and Germany, the accident precipitated a major change of policy direction. In the UK, debate has been muted and there has been essentially no change in energy or climate change policies. The status of the energy and climate change policies in each country prior to the accident is assessed, the responses to the accident are described, and the possible impacts on their positions in the international climate negotiations are analysed. Finally, the three countries' responses are compared and some differences between them observed. Some reasons for their different policy responses are suggested and some themes, common across all countries, are identified. Policy relevance: The attraction of nuclear power has rested on the promise of low-cost electricity, low-carbon energy supply, and enhanced energy independence. The Fukushima accident, which followed the Japanese tsunami of March 2011, has prompted a critical re-appraisal of nuclear power. The responses to Fukushima are assessed for the UK, Germany, and Japan. Before the accident, all three countries considered nuclear as playing a significant part in climate mitigation strategies. Although the UK Government has continued to support nuclear new build following a prompt review of safety arrangements, Japan and Germany have decided to phase out nuclear power, albeit according to different timescales. The factors that explain the different decisions are examined, including patterns of energy demand and supply, the wider political context, institutional arrangements, and public attitudes to risk. The implications for the international climate negotiations are also assessed.

Description: The European electricity market is linked to a carbon market with a fixed cap that limits greenhouse gas emissions. At the same time, a number of energy efficiency policy instruments in the EU aim at reducing the electricity consumption. This article explores the interactions between the EU's carbon market on the one hand and instruments specifically targeted towards energy end-use efficiency on the other hand. Our theoretical analysis shows how electricity demand reduction triggered by energy efficiency policy instruments affects the emission trading scheme. Without adjustments of the fixed cap, decreasing electricity demand (relative to business-as-usual) reduces the carbon price without reducing total emissions. With lower carbon prices, costly low emission processes will be substituted by cheaper high emitting processes. Possible electricity and carbon price effects of electricity demand reduction scenarios under various carbon caps are quantified with a long-term electricity market simulation model. The results show that electricity efficiency policies allow for a significant reduction of the carbon cap. Compared to the 2005 emission level, 30% emission reductions can be achieved by 2020 within the emission trading scheme with similar or even lower costs for the industrial sector than were expected when the cap was initially set for a 21% emission reduction.

Description: Climate change and thus low-carbon transitions are global challenges, which require commitment and effort on all political levels. As international climate politics has approached its limits over the last two decades, the role of cities has simultaneously gained in importance. Many cities1 worldwide have committed to ambitious climate protection targets, which often exceed national targets. However, cities cannot act in isolation. Their opportunities for action are embedded in an (inter)national policy framework, which may either support or hinder local actions. This gives rise to the question: which opportunities for climate protection do cities really have in a political system of multi-level governance? This question can be illustrated using the city of Hamburg as an example for the German climate policy regime. The city aims to reduce its annual CO2 emissions by 2 million metric tons and attempts to quantify the impact of local and national policies and actions using a bottom-up monitoring approach. We therefore analyse more than 400 local actions with respect to the induced CO2 emission reductions. We also take a closer look at national and European policies and their impacts on local energy use and emissions. In total, 15 policies and instruments - broadly ranging from instruments to foster energy efficiencyin residential and non-residential buildings, in appliances and in the transport sector, to support renewable energy sources (including biofuels) and to uptake CHP - are considered. Our approach consists in measuring separately the impact of local and national policies and actions on urban CO2 emissions. While the city of Hamburg has implemented many policies and actions, our results show that, a significant proportion of its CO2 reduction is due to national policies, in the context of the German "Energiewende", which cannot or can only indirectly be influenced by the city. The results imply that local commitment and effort is essential in addressing the global challenge, yet ambitious targets can only be met in the presence of a supportive national policy framework. The analysis shows that many policies and measures implemented at national level require supportive structures and activities at local level in order to bridge information and implementation gaps of these measures.

Description: Many European city governments have voluntarily committed to ambitious CO2-emission reduction targets until 2020 and 2050. Supported by dedicated structures and networks (e.g. Covenant of Mayors), local governments have already developed, or are currently developing, ambitious climate action plans, all pursuing the aim of radical CO2-emission reduction in the long term. Though, the development of climate action plans is only a first step, as the actual crucial and more challenging part its implementation. Besides financial investments also additional capacities, improved institutional structures and innovative strategies are necessary to successfully implement ambitious policies within existing national and regional framework conditions. There is often more competition than co-operation between cities. However, exchanging on common challenges in order to find new solutions provides potential for innovative ideas and new views on own structures. In particular, methods and formats for self-assessment and mutual learning can support cities' stakeholders to overcome their implementation gap in local energy and climate policies. This paper will present results from the first phase of the three year project "CASCADE", which was initiated by 19 European cities in co-operation with EUROCITIES. Within the project, implementation challenges are being addressed in an intensive process of self-assessment and mutual learning. The methodological "backbone" of this process is a qualitative benchmarking framework in the thematic fields of "Renewable energy sources and distributed energy generation", "Energy efficient buildings and districts" and “Energy in urban transport”. Up to a certain degree, existing local climate policy benchmarks provide a common exchange platform, but mainly for the comparison between cities. The CASCADE benchmarking framework goes beyond competitive comparisons. As a qualitative criteria-based assessment procedure it identifies key challenges and factors for a successful implementation of established local climate policy plans. These factors have been developed from a qualitative survey including interviews and workshops with representatives of the participating cities. Six cities serve as examples. Self-assessment reports were provided based on the CASCADE benchmarking framework focussing on the implementation status of their local climate policies. These reports were reevaluated by four or five project partners from different cities in a desk-review process. During subsequent four-days peer learning visits, the CASCADE benchmarking framework was used again as a tool for an in-depth assessment of the local climate and energy action plans and the local activities towards implementation of these strategic documents. Finally, the visitors drafted a feedback report with recommendations and improvements for the hosts. The paper describes the methodology of the CASCADE benchmarking framework for integrated learning, its applicability for peer learning processes, as well as first experiences and results from the peer learning visits.

Description: The project "bigEE - Bridging the Information Gap on Energy Efficiency in Buildings" presents comprehensive information for energy efficiency in buildings and the related policy on the international internet-based knowledge platform bigee.net. To develop the evidence-based information required for bigee.net, we addressed in a different and more systematic way than usual the question of how policy can support improved building energy efficiency most effectively: We combined (1) a theoretical, actor-centred analysis of market-inherent barriers and incentives for all actors in the supply and use chain of (energy-efficient) buildings to derive a recommended package combining the types of policies and measures the actors need to overcome all these barriers, with (2) empirical evidence on model examples of good practice policy packages to check if advanced countries have indeed used the combination of policies we derived from the actor-centred analysis. In this way, we found that the recommendable policy package for new buildings is similar to the well-known one for appliances, but with the objective to mainstream nearly zero energy buildings. By contrast, the task for existing buildings is two-dimensional - increasing the depth of renovation first, to savings of 50 to 80%, and then the rate of energy-efficient renovation to 2% or more p.a. - and so the policy package needs more emphasis on individual advice, incentives, and financing. The paper presents the recommended packages as well as a comparison of existing national policy packages from California (USA), China, Denmark, Germany, and Tunisia and what we learned from it for effective packages and implementation.

Description: The river Emscher is - similar to the river Ruhr - the symbol of one of the internationally most renowned industrial regions: the Ruhr area with its 5 million inhabitants and an important location of key industries such as steel, chemical and materials industry. The revitalisation of the Emscher over the last 20 years marks a new phase in the region's history and is an impressive example of ecological and socio-economic transformation affecting all aspects of life along the river. What can we learn from the Emscher conversion for upcoming tasks in other infrastructure fields?

Description: Considering global warming, increasing commodity prices, and the dramatic consequences of the over-exploitation and overuse of resources, a transition to a renewable energy supply is necessary. This requires an (resource) efficient and renewable supply of operating reserve. In this article, a possible solution to this problem is analysed: the Desertec concept. It is meant to convert solar energy in areas with high solar irradiation into electrical energy by means of Concentrated Solar Power (CSP) transferring this energy by High Voltage Direct Current (HVDC) lines into the whole European Union Middle East and North Africa (EU-MENA) area. In order to assess the resource efficiency potential of Desertec, three different kinds of CSP plants (parabolic trough, Fresnel collector and central receiver of the building classes Inditep, Novatec and Solar Tres) including heat storage systems (Molten Salt and Phase-Changing-Material) and the necessary HVDC are analysed using the Material Input per Service Unit (MIPS) methodology. The assessment is accomplished for three different locations (Morocco, Tunisia and Egypt) and two points of time (2025 and 2050). With these results, a scenario of electricity supply in Germany in 2050 with a 20% share of solar power import is calculated. Central receivers are the most resource efficient ones: their consumption of abiotic materials is only half of parabolic trough plants and two thirds of Fresnel trough plants. Water and air consumption is the lowest of all analyzed CSP plants as well. The scenario for Germany's fuel mix in 2050 shows that a predominantly renewable fuel mix reduces the consumption of abiotic materials by 75%, of water by 60% and of air by 45%. Only the consumption of biotic materials rises due to the higher share of biomass conversion.

Description: The role of cities in mitigating GHG emissions and thus tackling global warming has gained importance over the last years.Many cities have developed climate action plans, primarily to achieve long-term "low-carbon" mitigation goals set by national governments or (inter)national agreements. A mere adoption of high level targets, however, raises the question whether these targets are applicable for cities with very different framework conditions. We argue that it is crucial to understand the socio-economic, geophysical, spatial, infrastructural and political framework of a city - a broad approach, which is generally missing in climate action plans. Thus, determining drivers and barriers for future development paths is neglected by local policies, which leads to a gap between ambition (target) and reality (implementation). We exemplarily examine this hypothesis for the shrinking city of Oberhausen (Germany). Oberhausen, located in the Ruhr area,is a typical old industrial region, which has seen a decline of its industrial basis over the last decades. We analysed historical data and developed scenarios until 2030. Both show a significant decrease in CO2 emissions. A closer look, however, reveals that the reduction is primarily due to the economic transformation (less manufacturing, more service industry, accompanied by a decrease in population) and general energy efficiency developments following the implementation of national and EU policies. Although the city has implemented–and will further implement - many instruments and policies to reduce CO2 emissions, local barriers such as unemployment, low rents, low income, high per capita debts, etc. dramatically reduce the city's capacity for action. The results show that Oberhausen's emission reductions do not reflect active energy policies but are mainly driven by an economic decline. To reach ambitious reduction targets, however, the city needs to be enabled to take action in achieving appropriate and reasonable targets.

Description: Conventional new buildings in OECD countries with a history of building codes save about 50 % of energy compared to average buildings in the building stock. This improvement, however, is not enough to create a building standard with low lifetime costs nor to reach long-term climate protection targets. Much higher energy savings can already be achieved through proven high-efficiency building concepts bringing net economic benefits among other advantages. A strategic approach to integrated building design is the key to achieving these high-energy savings at low or no extra cost in residential buildings. In our paper we describe the "Easy Efficiency Approach", which can reduce primary energy consumption by 40 to 60 % compared to conventional new building standards, or by 70% to 80% when compared to the primary energy consumption of the existing building stock, and should be regarded as the minimum. This strategy focuses on low-cost options, mainly passive options. Although it can already significantly reduce energy consumption, this first step will not be sufficient to reach long-term climate protection goals. It is thus necessary to implement and support what we call an "Advanced Efficiency Approach", with savings up to 90% , as compared to new building standards, as soon as possible to avoid lock-in effects. Further improvements, especially through the active use of renewable energies, reduce the net primary energy demand to 0 % and beyond. According to the chosen strategy clearly defined energy performance ranges, with reference to possible savings, for different climate zones worldwide are given. In verifying this approach simulations with BAT (Best Available Technologies) buildings of different types (single family, multi family, high rise) were carried out in close cooperation with project partners. This data has also been verified through an empirical database of built examples both for energy consumption as well their economic soundness.

Description: The article argues for a need to overcome a conventional notion of product design. In this regard, the article offers an integrative and systemic approach to sustainable design. Instead of focusing on objects, a user-centred perspective is adopted. A sustainable design of products and services requires the integration of production-orientated (efficiency and consistency) and consumption-orientated (sufficiency) strategies. The article introduces the concept of an indicator that is capable of comprehending a lifecycle-wide analysis of products and that favours the integration of existing sustainability strategies. The goal is not to design sustainable products but rather to design systems that manage to foster sustainable lifestyles. The article illustrates the usability of the introduced concept by showing examples of strategic integrative thinking in sustainable design from the Sustainable Summer Schools.

Description: The Durban Climate Conference agreed on the creation of a new market-based mechanism under the United Nations Framework Convention on Climate Change (UNFCCC) and to consider the establishment of an overall framework for various mitigation approaches, including opportunities for using markets ("Framework"). The creation of such a Framework is therefore of high political significance, as it should ensure on the one hand that new market-based mechanisms contribute to global climate change mitigation and to achievement of targets, and on the other hand, that different market-based approaches can be integrated in a global carbon market. As yet, there is little clarity as to the roles and design of such a framework. This paper contributes to the debate by discussing and evaluating inter alia several design options, and explores how the various options could be implemented and how they interrelate. It concludes that a strong central oversight at the level of the UNFCCC is probably the only option that could reassure the vast majority of UNFCCC Parties that the environmental integrity of new market-based mechanisms is in fact ensured. This does, however, not exclude that some reasonable balance may be struck between centralization and flexibility.

Description: Carbon recycling, in which organic waste is recycled into chemical feedstock for material production, may provide benefits in resource efficiency and a more cyclical economy - but may also create "trade-offs" in increased impacts elsewhere. We investigate the system-wide environmental burdens and cost associated with carbon recycling routes capable of converting municipal solid waste (MSW) by gasification and Fischer-Tropsch synthesis into ethylene. Results are compared to business-as-usual (BAU) cases in which ethylene is derived from fossil resources and waste is either landfilled with methane and energy recovery (BAU#1) or incinerated (BAU#2) with energy recovery. Monte Carlo and sensitivity analysis is used to assess uncertainties of the results. Results indicate that carbon recycling may lead to a reduction in cumulative energy demand (CED), total material requirement (TMR), and acidification, when compared to BAU#1. Global warming potential is found to be similar or slightly lower than BAU#1 and BAU#2. In comparison to BAU#2, carbon recycling results in higher CED, TMR, acidification, and smog potential, mainly as a result of larger (fossil-based) energy offsets from energy recovery. However, if a renewable power mix (envisioned for the future) is assumed to be offset, BAU#2 impacts may be similar or higher than carbon recycling routes. Production cost per kilogram (kg) MSW-derived ethylene range between US$1.85 and US$2.06 (Jan 2011 US$). This compares to US$1.17 per kg for fossil-based ethylene. Waste-derived ethylene breaks even with its fossil-based counterpart at a tipping fee of roughly US$42 per metric ton of waste feedstock.

Description: The main objective of this article is to evaluate CO2 mitigation potential and to calculate costs avoided by the use of different CO2 mitigation technologies in China's cement sector, namely energy efficiency improvements, use of alternative fuels, clinker substitution and carbon capture and storage (CCS). Three scenarios are designed based on the projection of cement output and technology development over the next 40 years (2010–2050). 2.5, 4.7 and 4.3 Gt tonnes of CO2 will be saved totally in basic scenario and two low carbon scenarios up to 2050. By comparing these technologies along the scenarios, it can be concluded that CO2 emissions can mainly be reduced by energy efficiency improvements and use of alternative fuels. Clinker substitution, which reduces the clinker-to-cement ratio as well as energy intensity, results in significant cost advantages. CCS, including post-combustion capture and oxy-fuel combustion capture, could play an important role in the capture of CO2 in the cement industry, and is expected to be in commercial use by 2030.
