Description: To contribute to a better understanding of consumer food leftovers and to facilitate their reduction in out-of-home settings, our study analyzes the effects of two common intervention strategies for reducing leftovers in a holistic behavioral model. Based on a quasi-experimental baseline-intervention design, we analyzed how the display of information posters and the reduction of portion sizes take an effect on personal, social and environmental determinants in a structural equation model. Applying data from online surveys and observations among 880 guests (503 baseline, 377 intervention) during two weeks in a university canteen, the suggested model allows to assign effects from the two interventions on plate leftovers to specific changes in behavioral determinants. Portion size reductions for target dishes are found to relate to lower levels of plate waste based on conscious perception, represented in smaller portion size ratings. Effects from seeing information posters are found to base on changed personal attitudes, subjective norms and perceived behavioral control. However, depending on how an individual reacts to the information (by only making an effort to finish all food or by making an effort and additionally choosing a different dish in the canteen) there are opposite effects on these determinants and consequently also on plate leftovers. Overall, the differentiated results on intervention effects strongly support the benefits of more holistic and in-depth analyses of interventions to reduce plate leftovers and therefore to contribute to more sustainable food consumption in out-of-home settings.

Description: Addressing food waste prevention is one target of the Sustainable Development Goals (SDGs) and a major task for the UN Environmental Programme and the European Commission. It is promising in terms of its environmental saving potential. However, it also leads to consumers being able to save money, which they then are likely to spend, thus again causing a negative environmental impact. This dimension of the so-called indirect rebound effect, which prevents the desired ecological benefits from being achieved, is investigated in this paper. By using a single-region environmentally extended input-output model from a production perspective, the indirect rebound effects from food waste prevention in Germany are analysed. Any political action needs to consider not only a differentiation in income class, but also alternative concepts such as the principles of sufficiency in order to achieve all ecological benefits and specifically the third target of SDG 12.

Description: The concept of sufficiency - reducing energy uses beyond technical efficiency - is far-reaching and requires a reflection on human needs, energy services, urban structures, social norms, and the role of policies to support the shift towards lower-energy societies. In recent years, a growing body of literature has been published on energy sufficiency in various disciplines. However, there has been limited exchanges and cooperation among researchers so far, hindering the visibility and impact of this research. This paper presents an assessment of where sufficiency research stands, especially in the perspective of policy-making. It is the first overview paper issued in the context of the newly-founded ENOUGH network - International network for sufficiency research & policy, established in 2017. In the first part, we provide a condensed literature review on energy sufficiency, based on dozens of recent references collected through the network. Through four main themes (the nature of sufficiency, the challenges of modelling it, the barriers to its diffusion, and the approaches to foster it), we summarise the key issues and approaches. We then present what the scholars themselves see as the priorities for future research, promising sufficiency policy options, and key barriers that research should help overcome. We collected their views through a questionnaire completed by more than 40 knowledgeable authors and experts from various disciplines. We finally build on the previous parts to draw some recommendations on how sufficiency research could increase its impact, notably in relation to policy-making.

Description: The Paris Agreement introduces long-term strategies as an instrument to inform progressively more ambitious emission reduction objectives, while holding development goals paramount in the context of national circumstances. In the lead up to the twenty-first Conference of the Parties, the Deep Decarbonization Pathways Project developed mid-century low-emission pathways for 16 countries, based on an innovative pathway design framework. In this Perspective, we describe this framework and show how it can support the development of sectorally and technologically detailed, policy-relevant and country-driven strategies consistent with the Paris Agreement climate goal. We also discuss how this framework can be used to engage stakeholder input and buy-in; design implementation policy packages; reveal necessary technological, financial and institutional enabling conditions; and support global stocktaking and increasing of ambition.

Description: Ex-ante policy evaluation requires a detailed understanding of how the subjects addressed by the policy react to its implementation. In the context of energy efficiency, policy measures typically aim at influencing investment decisions towards more efficient options. As has been discussed widely in the context of the "energy efficiency gap", investments in energy efficiency improvements are frequently not conducted even though they seem cost-effective from a simple cost-benefit perspective, where transaction costs have been identified as one important barrier. While transaction costs have been discussed widely from a conceptional perspective, empirical studies quantifying transaction costs and measures to reduce them are rare. This paper presents approaches, results and insights from a recently completed research project funded by the German Federal Energy Efficiency Center (BfEE), addressing transaction costs in various energy efficiency measures and the role of energy efficiency services to overcome the barrier. We analyse a set of 11 energy efficiency investments covering private households, public institutions and the industry sector. We gather data on direct investment costs and energy cost savings and provide a detailed analysis of the various barriers and transaction costs associated with the implementation. We then analyse the costs of existing energy efficiency services using data provided by the BfEE. We compare the different cost elements and analyze the potential of energy efficiency services to reduce transaction costs. We find that the role of transaction costs differs substantially between households, public institutions and companies and that the impact of energy efficiency services on transaction costs needs to be evaluated using different methodological approaches. We conclude that while data availability on disaggregated transaction costs is a major challenge, energy services can reduce transaction costs considerably.

Description: In 2016, the European Commission presented the Clean Energy for all Europeans Package , comprising legislative proposals to facilitate the clean energy transition within the EU, such as the revised EPBD 2010/31/EU and EED 2012/27/EU.Besides putting energy efficiency first and achieving global leadership in renewable energy, a third goal of the package was to provide a "fair deal to consumers" with "no one left behind"., While in some Member States the issue of energy poverty already was on the political agenda, enabling affordable access to basic energy services for all households and thus reducing energy poverty is now an explicit policy target of the revised EU Directives. In order to assess and monitor the extent of the issue across the EU and address it by suitable measures, the concept of energy poverty needs to be defined, operationalised and measured. The paper aims to investigate the role of energy poverty indicators for policy making. To do so, it provides an overview on existing measurement approaches.Furthermore, the paper presents the development and current state of energy poverty across the EU using a set of four complementary indicators used by the EU Energy Poverty Observatory. These consensual and expenditure-based indicators are calculated using data from the EU Survey on Income and Living Conditions and the Household Budget Survey. In addition, the paper highlights peculiarities of results on the different indicators, describes persisting issues with regard to their calculation and interpretation against the background of the underlying data base. Based on the results of this analysis, further necessities of data collection and research are pointed out.

Description: Because prevention is closely linked to complex consumption patterns, even cultural changes, such as increasing environmental awareness, changes in the average size of households or changes in the industrial structure of an economy, are relevant factors for the interpretation of changes in the generation of waste - it is more or less impossible to isolate the effect of specific waste prevention measures in this complex system. This must be considered, in particular, in international comparisons of policies and their potential transferability. The guidelines of the European Commission on waste prevention also point to the particular problem of data availability in the area of prevention: as waste statistics focus mainly on the treatment and fate of wastes, they are often of limited value for prevention of waste because they don't give sufficient information about their origins or reasons for their generation. Against this background, this report has the following objectives: Chapter 2 discusses strengths and weaknesses of typical waste-based prevention indicators; Chapter 3 analyses possible indicators that consider an upstream perspective and take into account the ecological rucksacks of products and components that have become waste; Chapter 4 focuses on specific product groups that could be targeted by waste prevention indicators. In general, the report describes the complexity of measuring waste prevention and outlines pros and cons of possible approaches. The final chapter aims to draw rather pragmatic conclusions on possibly most preferable options for future policy-making.

Description: In The Birth of Energy Cara New Daggett traces the genealogy of contemporary notions of energy back to the nineteenth-century science of thermodynamics to challenge the underlying logic that informs today's uses of energy. These early resource-based concepts of power first emerged during the Industrial Revolution and were tightly bound to Western capitalist domination and the politics of industrialized work. As Daggett shows, thermodynamics was deployed as an imperial science to govern fossil fuel use, labor, and colonial expansion, in part through a hierarchical ordering of humans and nonhumans. By systematically excavating the historical connection between energy and work, Daggett argues that only by transforming the politics of work—most notably, the veneration of waged work—will we be able to confront the Anthropocene's energy problem. Substituting one source of energy for another will not ensure a habitable planet; rather, the concepts of energy and work themselves must be decoupled.

Description: The author demonstrates that digital technologies and new mobility concepts can lead to a reduction of the automobiles in urban areas by a factor of 10. The book features two vivid case studies of such digital mobility concepts: TwoGo by SAP and smexx. The author proposes six prototypes of business models for "Shared Automobility Services". Janasz offers also the "Transformative Literacy" for designing sustainable urban mobility systems of the future. The author elaborates on the socio-political patterns of urban mobility by presenting the case of the City of Basel (Switzerland). He proposes the framework of "Integrated Sustainable Urban Mobility" to explain how to overcome car dependence in cities.

Description: This governance brief aims to provide practical examples on how investments in urban infrastructure, clean energy, and energy efficiency can be implemented; and how these are embedded in multi-level governance, experimentation, and policy-learning. It draws on examples from the German energy system transition, which can be understood as a large-scale, real-life laboratory for the governance of a sustainability transition of an entire national energy system. The federal state of North-Rhine Westphalia's experience illustrates the complexity of the governance challenge of implementing low-carbon system transitions.

Description: Climate change induces various risks for supply chains of manufacturing firms. However, surveys have suggested that only a minority of firms conducts strategic adaptations, which we define as anticipatory and target-oriented action with the purpose of increasing resilience to climate change. While several barrier-centered studies have investigated the causality of non-adaptation in industry, the examined barriers are often not problem-specific. Furthermore, it has been shown that even in cases when managers perceive no barriers to adaptation at all, strategic adaptations may still not be conducted. On this background, the present analysis focuses on the logic of adaptive inaction, which we conceive, in particular, as inaction with regard to strategic adaptations. Adopting an action-theoretical perspective, the study examines (a) which aspects may shape the rationality of adaptive inaction among managers, (b) which more condensed challenges of conducting strategic adaptations emerge for managers, and (c) how the theoretical propositions can be tested. For this purpose, the study employs an exploratory approach. Thus, hypotheses on such aspects are explored, which may shape the rationality of adaptive inaction among managers. Subsequently, predictions are inferred from the theoretical propositions, which allow testing their empirical relevance. Methodologically, the hypotheses are explored by reexamining existing explanatory approaches from literature based on a set of pretheoretical assumptions, which include notions of bounded rationality. As a result, the study proposes 13 aspects which may constrain managers in conducting adaptations in such a way, which serves the economic utility of the firm. By condensing these aspects, 4 major challenges for managers are suggested: the challenges of (a) conducting long-term adaptations, of (b) conducting adaptations at an early point in time, of (c) conducting adaptations despite uncertain effects of the measures, and of (d) conducting adaptations despite cross-tier dependencies in supply chains. Finally, the study shows how the propositions can be tested and outlines a research agenda based on the developed theoretical suggestions.

Description: Real-world laboratories (RwLs) often put researchers in highly demanding research contexts regarding their roles and self-conceptions. Helpful roles of researchers have been described but still little is known about the factors influencing the adoption of certain roles. Using data from three parallel RwLs in Wuppertal, Germany, we found four roles of researchers: the reflective scientist, the facilitator, the change agent and the (self-)reflexive scientist. We sequenced the RwLs into situations and analysed them by RwL process steps and conditions, considering the roles of researchers as outcomes. Although the conditions convey only limited explanatory power, there was a consistent picture that being pressured to carry out real-world action, having a practice partner with fewer resources and working without a functional project group is (in conjunction) sufficient to cause the researcher to partake in activities beyond conventional research. Process steps played a minor role. Our research on factors influencing the adoption of roles may help RwL researchers to perform their roles as intended.

Description: Energy sufficiency has recently gained increasing attention as a way to limit and reduce total energy consumption of households and overall. This paper presents both the partly new methods and the results of a comprehensive analysis of a micro- and meso-level energy sufficiency policy package to make electricity use in the home more sufficient and reduce at least the growth in per-capita dwelling size. The objective is to find out how policy can support households and their members, as individuals or as caregivers, but also manufacturers and local authorities in practicing energy sufficiency. This analysis needed an adapted and partly new set of methods we developed. Energy sufficiency does not only face barriers like energy efficiency, but also potential restrictions for certain household members or characteristics, and sometimes, preconditions have to be met to make more energy-sufficient routines and practices possible. All of this was analysed in detail to derive recommendations for which policy instruments need to be combined to an effective policy package for energy sufficiency. Energy efficiency and energy sufficiency should not be seen as opposed to each other but work in the same direction - saving energy. Therefore, some energy sufficiency policy instruments may be the same as for energy efficiency, such as energy pricing policies. Some may simply adapt technology-specific energy efficiency policy instruments. Examples include progressive appliance efficiency standards, standards based on absolute consumption, or providing energy advice. However, sufficiency may also require new policy approaches. They may range from promotion of completely different services for food and clothes cleaning, to instruments for limiting average dwelling floor area per person, or to a cap-and-trade system for the total electricity sales of a supplier to its customers, instead of an energy efficiency obligation.

Description: Background: For a successful transition to a sustainable energy system, not only technical but also social innovations are required. A major challenge to social innovation research is how to translate the social innovation from a novelty with big potential into a mainstream practice. The multilevel perspective (MLP) of socio-technical transitions provides a heuristic to understand how niches can potentially break through to the regime level. In this paper, we examine in how far a multilevel perspective approach is suited to analyze and better understand diffusion trajectories of social rather than technological innovations, taking a social practice theory perspective. Five example projects, selected among the top social innovations for the Energiewende in North Rhine-Westphalia, are analyzed. We discuss to what extend the MLP provides a helpful tool to understand the transition processes. Results: Social innovations can be very divers. We find that the MLP does not offer a one-size-fits-all framework for the analysis of the diffusion of social innovations. The MLP proves applicable only in those cases where the social innovation (1) can lead to a system change and (2) has a clear competing or symbiotic relationship with an existing regime. Conclusions: Social innovations that aim to be transformative in the sense that they have the goal to be system changing (rather than incremental) can be analyzed along the heuristics of the MLP. For this type of social innovation, the MLP can be fruitful to learn to better understand the diffusion dynamics of social innovation and the barriers and drivers they might face. However, for social innovations that aim at incremental improvements without challenging the existing system, the MLP cannot be applied to study the diffusion process.

Description: As part of this dissertation, a categorisation of the social costs of electricity supply is suggested. The following three main cost categories are differentiated: plant-level costs, system costs and external costs. Different types of costs are allocated to these categories and are examined and quantified (to the extent possible) for several power generation technologies. The limits of monetizing certain types of costs are also discussed. In a further step, and based on a large number of empirical studies, individual factors that have had a significant influence on the development of plant-level costs in the past, are identified and categorized. Finally, based on an online survey conducted among energy modellers, the dissertation examines to what extent the identified relevant types of costs and cost-influencing factors are taken into account in different types of energy models.

Description: Germany's waste management system is one of the world's most advanced - its primary objective is to dispose of waste in a way that is safe for both people and the environ- ment. However, only about 14 per cent of the raw materials used in industry are derived from recycling processes; the remainder are still sourced from primary materials. The circular economy is not yet being implemented on a large enough scale. Recyclates or recycled materials, i.e. secondary raw materials recovered from waste, are being fed back into production and usage processes at volumes that are far below what is possible. If this system were to be improved, loss of value, dependence on volatile commodity markets, lower resource productivity, and externalities in the form of environmental pollution could be avoided. A drive towards digitalisation in industry and the waste management sector could make this happen. A study by the German Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMUB) indicates that no other lead market in the environmental sector stands to benefit from digitalisation more than the circular economy - and that, at the same time, no sector has ever been so poorly positioned.

Description: In addition to the expansion of renewable energies, the efficient use of energy is crucial in order to ensure energy transition successful. The Federal Government of Germany has therefore set itself clear objectives with the National Energy Efficiency Action Plan (NAPE), which aims to reduce the primary energy consumption in Germany - compared to 2008 levels - by 20 per cent until 2020, and by 50 per cent until 2050. In addition, greenhouse gas emissions should fall by 40 per cent compared to 1990. To reach this goal, the German Federal Ministry of Economic Affairs and Energy (BMWi) inter alia launched the "National Top Runner Initiative (NTRI)" in January 2016. It is an important component and concerns private homes, as well as industry, retail and services. The NTRI is intended to bring energy efficient and high-quality appliances (so called Top Runners) onto the market more quickly, thus accelerate market replacement. For this purpose, motivation, knowledge and competence in product-related energy efficiency is to be strengthened and expanded along the whole value chain - from the appliance manufacturer to the retailer and the consumer. Manufacturers are pushed to develop more efficient products and consumers get valuable information about Top-Runner products and how they can benefit. In this context, retailers are especially relevant as they act as "gatekeeper" between manufacturers and consumers. They play a key role in advancing an energy efficient production and consumption. They do not only select the products but they also have a direct contact to consumers and influence the purchase decision. In this paper, special emphasis will be put on the role of retailers and the efforts of the National Top Runner Initiative will be illustrated. Barriers and incentives to motivate this target group will be elaborated.

Description: Digital platforms may yield a host of advantages in putting circular economy into effect. This paper analyses the related chances and discusses requirements of digital platforms for the realization of a circular economy. It specifically points to potential solutions offered by digital platforms for existing barriers. From there it identifies issues that need specific attendance to create economically and ecologically functional platforms. Three economically relevant perspectives are discussed for this: a management perspective, a legislative perspective and a social/systems perspective.

Description: Poor households in Germany and those that are close to the poverty line are more likely to suffer from increases in electricity costs. One consequence of this is the increasing number of cases in which the supplier disconnects a household's power. According to the Federal Network Agency (Bundesnetzagentur), a total of almost 359,000 interruptions of the electricity supply were caused in 2015 due to outstanding payments. In order to avoid disconnection from the electricity grid, more and more utility companies have begun to offer prepayment meters (PPMs) to their customers as a response to outstanding payments and a growing number of customers owing debts to their energy supplier. The phenomenon of an increasing number of households affected by energy poverty in Germany is new, and thus the number of PPMs is still low. As a result, experiences in this context are - compared to other countries (e.g. Great Britain) - far from extensive, and political awareness of the problem is low. This paper presents the findings of Germany's first scientific survey on experiences with the use of PPMs.

Description: Alternative power initiatives are socio-ecological innovations that substantially contribute to city's sustainable development and, therefore, are of particular societal benefit and value. Cities should, consequently, have an inherent interest in their existence and proliferation. This, however, asks for strategic innovation management. While, acknowledgement of the project's innovativeness constitutes the precondition for management, in the further process of steering activity the tasks to reduce hurdles, create open space and support the project's capacities need to be mastered. Thereby, cities are increasingly asked to become innovative themselves in order to find ways to optimally make use of their available tools and capacities.

Description: Various electricity generation technologies using different primary energy sources are available. Many published studies compare the costs of these technologies. However, most of those studies only consider plant-level costs and do not fully take into account additional costs that societies may face in using these technologies. This article reviews the literature on the costs of electricity generation technologies, aiming to determine which types of costs are relevant from a societal point of view when comparing generation technologies. The paper categorises the relevant types of costs, differentiating between plant-level, system and external costs as the main categories. It discusses the relevance of each type of cost for each generation technology. The findings suggest that several low-carbon electricity generation technologies exhibit lower social costs per kWh than the currently dominant technologies using fossil fuels. More generally, the findings emphasise the importance of taking not only plant-level costs, but also system and external costs, into account when comparing electricity generation technologies from a societal point of view. The article intends to inform both policymakers and energy system modellers, the latter who may strive to include all relevant types of costs in their models.

Description: Optimization and simulation models are fit to work on a multitude of technical, economic, and techno-economic questions. However, they are by now not able to satisfactorily include societal aspects like acceptance, spatial implications and legal frameworks. In order to advance scope and explanatory power of simulation models, collaboration in interdisciplinary research teams is needed. Yet the exchange in such teams and its coordination can prove challenging. Furthermore, disciplinary approaches and methods for simulation and optimization might not be familiar to all participants. To this end, a new conceptual model is introduced. The conceptual model employs few basic elements and concepts for describing and explaining arbitrary societal and technical relationships. Most notably, the conceptual model is general in its design, so contributions to the problem formulation and design components can be made by all team members regardless of their discipline. The procedure is based on common agent-based concepts without using their terminology. Consequently, an exchange among all team members becomes possible without them necessarily being proficient in agent-based modeling. A reduced presentation of workshop results exemplifies the use of novel elements for deriving an emergent agent-based simulation.

Description: A fundamental change in societal values and economic structures is required to address increasing pressures on ecosystems and natural resources. Transition research has developed in the last decades to analyze the co-dynamics of technological, institutional, social and economic elements in the provision of key functions such as energy, water and food supply. This doctoral dissertation provides conceptual and methodological contributions to the pro-active governance of sustainability transitions. Three research gaps are identified that are addressed in this dissertation. First, a comprehensive conceptualization of learning in sustainability transitions is currently missing that comprises learning at multiple societal levels (ranging from individuals to policy-actors). Learning concepts are often not explicitly discussed in transition research even though learning is considered as fundamental for innovation processes, niche formation and development as well as breakthrough and diffusion of innovations. Second, methods for the analysis and design of transition governance processes are lacking that specify case-specific intervention points and roles of actors in the implementation of innovations. Third, participatory modeling approaches are only applied to a limited extent in transition research despite a high potential for supporting communication and learning. The conceptualization of multi-level learning developed in this doctoral research conceptualizes learning at different societal levels as specific learning contexts ranging from individual and group contexts to organizational and policy contexts. The conceptual framework further differentiates between learning processes, intensity, objects, outcomes, subjects and factors, allowing for a more detailed analysis of learning within and across learning contexts. Thus, learning contexts can be linked by processes that involve actors from different learning contexts (e.g., community groups and policy-makers), as well as exchanges of physical aspects, institutions and knowledge (in the form of "learning factors"). This research has also provided a classification of model uses in transition research that supports a purposeful discussion of the opportunities of modeling and promising future research directions. The methodology developed in this doctoral research aims at the analysis and design of transition governance processes by specifying the various opportunities to contribute to sustainability transitions through purposeful action at different societal levels, as well as related roles of stakeholders in implementing such processes of change. The methodology combines different streams of previous research: 1) a participatory modeling approach to identify problem perceptions, case-specific sustainability innovations as well as related implementation barriers, drivers and responsibilities; 2) a systematic review to identify supportive and impeding learning factors from the general literature that can complement case-specific factors; and 3) a method for the analysis and design of case-specific transition governance processes. Three case studies in Canada (topic: sustainable food systems), Cyprus (water-energy-food nexus) and Germany (sustainable heating supply) have been selected to test and iteratively develop the methodology described above. The results for each case study reveal that there are learning objects (i.e., learning requirements) in all learning contexts, which underscores the importance of multi-level learning in sustainability transitions, ranging from the individual to the group, organizational and policy levels. Actors have various opportunities to actively facilitate societal transformations towards sustainable development either directly through actions at their particular societal levels (i.e., context-internal learning) or indirectly through actions that influence learning at other societal levels. In fact, most of the learning factors require cooperation across learning contexts during the implementation process. The comparing of learning factors across case studies underline the importance of several factor categories, such as "physical a disturbance or crisis", "information and knowledge". Of the 206 factors identified by stakeholders, 40 factors are case-specific and not contained in the general, review-based factor list. This underscores the value of participatory research, as general, top-down analyses might have overlooked these case-specific factors. The methodology presented in this dissertation allows for the identification and analysis of case-specific intervention points for sustainability transitions at multiple societal levels. The methodology furthermore permits the analysis of interplay between individual, group, organizational and policy actions, which is a first step towards their coordination. The focus on sustainability innovations links the broad topic of sustainability transitions to a set of opportunities for practical interventions and overcoming their implementation barriers. The methodology presented allows for the analysis and design of these interlinkages between learning contexts. While the methodology cannot provide any "silver bullets" for inducing sustainability transitions, it is flexible enough to identify an appropriate abstraction level for analyzing and designing transition governance processes. The methodology developed in this doctoral research also provides several contributions for the development of participatory modeling methods in transition research. Thus, the participatory method supports an integrated analysis of barriers and drivers of sustainability innovations, and allows application in practice and education. The concepts and methods developed in this research project allow for reflection on transition governance processes from a systemic viewpoint. Experiences in the case studies underline the applicability of the concepts and methods developed for the analysis of case-specific transition governance processes. Despite substantial differences in the geographic location, culture and topics addressed, all case studies include promising sustainability innovations and the engagement of multiple actors in their implementation. The diversity and multitude of initiatives in the case study regions provides an optimistic outlook on future opportunities for large-scale sustainability transitions.

Description: 2015 was a watershed for international sustainability governance. With the Paris climate agreement and Agenda 2030, the international community adopted new targets and processes which are to guide policy for decades to come. Both emphasise the need for integration. In practice, however, climate change and sustainable development have so far been siloed issues.

Description: We present the results of a regression analysis of a large-scale integrated user online application that surveys natural resource use and subjective well-being in Germany. We analyse more than 44,000 users who provided information on their natural resource consumption (material footprint) as well as their personal socio-economic and socio-psychological characteristics. We determine an average material footprint of 26 tonnes per person per year. In addition, we endeavour to determine how much environment humans need by regressing natural resource use as well as relevant socio-economic and socio-psychological features on subjective well-being. We establish a slightly negative correlation between subjective well-being and material footprints. A higher material footprint is associated with lower subjective well-being. We conclude that consumer policies seeking to promote sustainable behaviour should highlight the fact that a lower material footprint may result in greater subjective well-being.

Description: After two decades of privatization and outsourcing being the dominant trends across public services, an inclination towards founding new municipal power utilities can be observed. In this article, the authors examine the preservation strategies of the German energy regime following the transition approach developed by Geels. From the multi-level perspective, it can be stated that innovations take place in niches and have to overcome the obstacles and persistence of the conventional fossil-nuclear energy regime. Through an empirical analysis, it can be concluded that the established regime significantly delays the decentralization process required for a transformation of energy structures on local electricity grids. Furthermore, it is shown that municipal utilities (Stadtwerke) are important key actors for the German Energiewende (energy transition) as they function as local energy distributors and they meet a variety of requirements to promote fundamental structural change. The trend towards re-municipalization and the re-establishment of municipal utilities reveal the desire to further strengthen the scope of local politics.

Description: Since the majority of network concession contracts in Germany were set to expire some time between 2005 and 2016, a window of opportunity arose in which to rebuild and remunicipalise the local energy supply. As a result, 72 new local power companies were established in Germany within the space of just seven years (between early 2005 and late 2012). This paper provides an introduction to the topic of establishing municipal utilities in Germany. The findings were identified on the basis of the comprehensive screening of all newly established municipal utilities in Germany. Our analysis provides information about regional concentration, the size of municipalities, the legal forms of the newly founded municipal public utilities and the role of strategic partnerships. The key findings are that remunicipalisation is not a question of size and that knowledge gaps may be closed by entering into close strategic partnerships.

Description: As the recent withdrawal of the United States from the Paris Agreement has shown, political volatility directly affects climate change mitigation policies, in particular in sectors, such as transport associated with long-term investments by individuals (vehicles) and by local and national governments (urban form and transport infrastructure and services). There is a large potential for cost-effective solutions to reduce greenhouse gas emissions and to improve the sustainability of the transport sector that is yet unexploited. Considering the cost-effectiveness and the potential for co-benefits, it is hard to understand why efficiency gains and CO2 emission reductions in the transport sector are still lagging behind this potential. Particularly interesting is the fact that there is substantial difference among countries with relatively similar economic performances in the development of their transport CO2 emissions over the past thirty years despite the fact that these countries had relatively similar access to efficient technologies and vehicles. This study aims to explore some well-established political science theories on the particular example of climate change mitigation in the transport sector in order to identify some of the factors that could help explain the variations in success of policies and strategies in this sector. The analysis suggests that institutional arrangements that contribute to consensus building in the political process provide a high level of political and policy stability which is vital to long-term changes in energy end-use sectors that rely on long-term investments. However, there is no direct correlation between institutional structures, e.g., corporatism and success in reducing greenhouse gas emissions in the transport sector. Environmental objectives need to be built into the consensus-based policy structure before actual policy progress can be observed. This usually takes longer in consensus democracies than in politically more agile majoritarian policy environments, but the policy stability that builds on corporatist institutional structures is likely to experience changes over a longer-term, in this case to a shift towards low-carbon transport that endures.

Description: The field of nutrition will face numerous challenges in coming decades; these arise from global consumption patterns and lead to a high use of resources. Actors in the catering sector face difficulties in promoting their solutions for a more sustainable situation in their field, one of them being the lack of acceptance from consumers. We must ask the question of how to influence consumer behavior and bring forth a transition towards more sustainable food consumption. This paper presents results of a qualitative assessment of eating practices. A group of ten consumers participated in problem-centered interviews and provided data on their eating-out behavior over the course of two weeks. Using the theoretical approach of practice theory, the data gathered in this study were used to form an understanding of the practice of eating out with a focus on the daily routines that influence consumer choices. The results indicate that the practice of eating out is highly dependent on external factors. Busy lifestyles, mobility routines and a perceived lack of time prompt the decision to eat out. Consumers consciously do so to save time and effort and to streamline their schedules. Mobility seems to be an important driver for eating out. Participants try to limit the ways they undertake eating out yet often stop for a meal in-between appointments spontaneously. Findings suggest that nutrition knowledge and sustainable mindsets have little influence on the eating decisions away from home: Participants show a high level of distrust towards quality claims and put their health concerns aside eating out. We can conclude that the act of eating out is strongly influenced by daily routines and those practices that precede or succeed it. Changes in work and mobility patterns are very likely to have an impact on the way consumers eat away from home.

Description: Against the background of environmental problems arising from the growing extraction of natural resources and resource depletion, achieving a sustainable development is an indispensable challenge in the twenty-first century. In this article we want to show how socio-technical and product-service innovations can change social practices - the routine doings in everyday life - and, thus, support transition of socio-technical systems. We introduce theoretical considerations on how social practice theories and the framework of the Multi-Level Perspective in transition research can be linked to better understand transition processes from a micro-macro-link perspective. We then present cases based on desk research in the field of practices in bathing, heating and nutrition to show how these have changed over the past decades. Building on this, examples of concepts for sustainable product-service-design in these areas are introduced as leverage points to change social practices in everyday life. These have been developed in research projects or design student seminar works, respectively. We argue that this implies sustainable product-service-systems should be developed in a user- and actor-integrated framework, such as Sustainable LivingLabs. The integration of users and other stakeholders into participatory co-creation processes enables tailored solutions that take actual routines and dependencies seriously into account.

Description: Urban areas provide space and place for experimentation with sustainability transitions in real-world laboratories. Members of the existing urban laboratories in Baden-Württemberg and experts have discussed the challenges of these innovative research settings, as well as possible solutions.

Description: Understanding the diversifying role of civil society in Europe's sustainability pathway is a valid proposition both scientifically and socially. Civil society organisations already play a significant role in the reality of cities, what remains to be explored is the question: what is the role of civil society in the future sustainability of European cities? We first examine the novelty of new forms of civil society organization based on a thorough review of recent case studies of civil society initiatives for sustainable transitions across a diversity of European projects and an extensive literature review. We conceptualize a series of roles that civil society plays and the tensions they entail. We argue that, civil society initiatives can pioneer new social relations and practices therefore be an integral part of urban transformations and can fill the void left by a retreating welfare state, thereby safeguarding and servicing social needs but also backing up such a rolling back of the welfare state. It can act as a hidden innovator - contributing to sustainability but remaining disconnected from the wider society. Assuming each of these roles can have unintended effects, such as being proliferated by political agendas, which endanger its role and social mission, and can be peeled off to serve political agendas resulting in its disempowerment and over-exposure. We conclude with a series of implications for future research on the roles of civil society in urban sustainability transitions.

Description: The German government aims to achieve virtually climate-neutral building stock by 2050 to tackle climate change. To realise this goal, comprehensive policy packages based on neoclassical economic theory are in place to foster energy efficiency investment. However, in the building sector, there is increasingly a gap between this aspiration and the reality. It is claimed that one of the main reasons for this is that the existing policy framework fails to address the specific characteristics and needs of different groups of building owners. This is a particular challenge in Germany, where 80% of all dwellings are owned privately and 37% are rented out by small private landlords (SPL). Despite the significant numbers of SPL, they often follow black box decision-making processes when considering energy renovations. In this study, the author uses an explanatory model to understand the decision-making processes of SPL, combining theoretical aspects from different research disciplines. This model was applied to a low-demand housing market in a neighbourhood in the Ruhr area. Eighteen semi-structured interviews (each lasting between 37 and 115 min) were conducted, demonstrating that in addition to economic factors, the values, beliefs, norms and routines of SPL - as well as their personal capabilities and contextual factors - play an important role in their decision-making. Based on the findings, recommendations are made for enhancing the effectiveness of existing energy efficiency policies and other supporting instruments (e.g. tenancy law and social legislation), tailored to the specific needs of SPL.

Description: A case study in the rural area of South Westphalia, Germany, showed the importance of independent intermediaries to support the development and implementation of sustainable energy and efficiency projects. The idea behind the project "Dorf ist Energie(klug)" (Village is Energy(smart)) was to foster, accompany, and support energy and efficiency projects in villages from the first idea to final implementation. Therefore, the South Westphalia Agency as independent intermediary initiated an application process in which villages could apply with their innovative energy and efficiency project ideas. During the following process the chosen "coaching villages" benefitted from the consultation of teams of thematic experts. Villages with less developed projects were supported through idea workshops with experts and study visits. The accompanying scientific study evaluated the overall process focussing on the transferability, the sustainability and the quality of the process. Furthermore, a self evaluation tool for (energy) projects in villages was developed and tested in two of the participating coaching villages. The paper gives a short insight into the project "Dorf ist Energie(klug)". It presents the methodology of the accompanying study and the results with a special focus on the role of the South Westphalia Agency as independent intermediary. Finally, it discusses the transferability and sustainability of the project.

Description: Real-world laboratories are growing in popularity promising a contribution to both: the understanding and facilitation of societal transformation towards sustainability. Baden-Württemberg substantially funds real-world labs as part of the initiative "science for sustainability". To facilitate learning with and from these so-called BaWü-Labs, they are supported by accompanying research conducted by two teams. This article presents first insights and theses on real-world labs as a research format, based in particular on the work of the accompanying research team ForReal. The team supports the labs in their realization and in providing general insights, e.g. by learning from related international research approaches and dialog with international experts, and analyzes suitable quality features and methods (the latter together with the University of Basel team). The theses presented here put up for discussion first insights on real-world labs as a transformative research approach and reflect on them from a theoretical perspective. They illustrate the relevance of a goal-oriented use of methods and present learning processes as core characteristics of real-world labs. The theses were formulated based on discussions with the BaWü-Labs, exchange in international contexts as well as a thematic literature review.

Description: With the introduction of the Roadmap to a Resource Efficient Europe (2011) and the more recent commitment of The Action Plan towards the Circular Economy (2015), the European Commission (EC) has expressed its fundamental interest to substantially improve the resource efficiency of the European economy and enable the transition towards the Circular Economy (CE). This policy push has meanwhile been complemented by some quite ambitious national programmes for RE and CE and institutional advances but it is not yet bound to targets or mandatory reporting. Against this background, the objective of this paper is to give a comprehensive overview of the current policy frameworks at EU and a selection of MSs and provide insights into the elements shaping policy processes. The analytical framework relies on three essential interconnected components: the policy framework, the economic incentive system and economic side policies which are relevant in the context of RE and CE and actor constellations. The paper does this looking at the interface between EU-MSs. The analysis is based on different empirical surveys in which the policy development is observed and discussed (EEA 2011, 2016a, 2016b, EIO 2013, 2014, 2016) and a comprehensive review of legislative and policy frameworks at the EU and selected MSs, undertaken as part of the project POLFREE (Policy option for a Resource-Efficient Economy) (Domenech et al., 2014, Bahn-Walkowiak et al., 2014). The analysis reveals that policy frameworks for RE/CE are complex and fragmented as competing goals and visions reduce effectiveness of measures. The paper makes recommendations as to how EU and MS policies could improve RE in a coordinated way, but recognizes that achieving such coordination will be challenging in the current political context.

Description: This article presents an account of how deeply entrenched the neoclassical economic paradigm with its homo economicus and unlimited growth ideals has become in our societies and why this inhibits solutions for sustainable futures. Drawing on political economists like Karl Polanyi and Antonio Gramsci it also highlights how the current questioning of this paradigm and thus informed mindsets provides a renewed window of opportunity for a Great Transformation towards more sustainable futures. It reviews Transition Towns, Beyond GDP and Common Good Economies as examples of movements that lead the way in putting a new paradigm into practice.

Description: Tackling fuel poverty has become an increasingly important issue on many European countries' political agendas. Consequently, national governments, local authorities and NGOs have established policies and programmes to reduce the fuel poverty vulnerability of households. However, evaluations of such policies and programmes show that they barely reach those who are most in need. The reasons for this failure are diverse and include fuel poverty measurement metrics, local scale data availability and policy design. This raises the question of how fuel poor homes can be more effectively identified and targeted to ensure that limited local and national budgets are used to benefit those who most need help. Area-based approaches, which pinpoint spatial units highly affected by fuel poverty due to their specific characteristics, offer an opportunity for creating more tailored policies and programmes. In this study, the author developed a GIS-MCDA (Multi-Criteria Decision Analysis), using an AHP (Analytical Hierarchy Process) and applied the approach to the German city of Oberhausen. The overall issue of fuel poverty was broken down into three vulnerability dimensions (heating burden, socio-economic and building vulnerability), the relative importance of fuel poverty criteria and the dimensions were evaluated by experts, and an overall Fuel Poverty Index was created to assess the relative fuel poverty vulnerability of 168 urban neighbourhoods. The analysis offers insights into the spatial pattern of fuel poverty within a city and thus provides an opportunity to channel efforts towards households in those neighbourhoods most in need. It also demonstrates that a trade-off between ecological and social targets should be considered in the development of future policies for tackling fuel poverty.

Description: The concept of multiple (economic, ecological, social and political) crisis has arisen from recent tumultuous economic events. This paper uses a feminist perspective to present the concept as a crisis of regeneration of both nature and social reproduction. We intend to go beyond multiple crisis using the notion of a new social contract, to overcome this crisis in a transformative way towards sustainability. A feminist analysis of the concept of social contract is founded on the critique of domination and is based on Carole Pateman's, 1988 thesis that the modern social contract is characterized by a "separating inclusion" of women. It also refers to Val Plumwood's critique of the separated and autonomous self, which is part of all classical conceptions of social contract. We argue that overcoming the multiple crisis requires overcoming structures of separation and re-envisioning concepts of the individual, by discussing the German example of a "Social Contract for Sustainability" (2011). If the notion of social contract is to become a catalyst for transformation processes leading to sustainability, it cannot be overarching but has to be developed as a multitude of small new social and local contracts.

Description: To identify the main drivers of transformation, it is helpful to identify the transformation perspectives of three specific schools of thought: idealist, institutional, and technological innovation. By differentiating among these schools of thought, a more informed transformation debate becomes possible, thereby increasing transformative literacy in academia and society.

Description: Real-world laboratories aim to create relevant and transferable knowledge and foster societal transformation towards sustainability. Members of the existing laboratories in Baden-Württemberg and experts have discussed the progress and the challenges of these innovative research settings.

Description: The transition towards full decarbonisation has reached the political agenda. In September 2016 in Wuppertal, scientists and politicians discussed ways to meet the climate targets.

Description: On the occasion of the 25th anniversary of the Wuppertal Institute for Climate, Environment and Energy, several events took place in Wuppertal under the motto of Making Utopia Possible.

Description: In the context of the larger sustainability discourse, "sufficiency" is beginning to emerge as a new value throughout Western societies, and the question asked in this article is: Can we observe and conceptually identify opportunities to link successful business strategies of incumbents to principles of sufficiency? Thus, how feasible is sustainable entrepreneurship for incumbents? In this paper, a conceptual approach is developed combining insights from sociology, transition research, management and sustainable entrepreneurship research with a focus on narratives as a translation mechanism in situations where tensions emerge between corporate narratives and unexpected societal trends, e.g., the emergence of sufficient lifestyles. It will be shown that even though these are still a niche phenomenon, a focus on corporate narratives is an important element in understanding the role of incumbents in transitions to sustainability.

Description: The International Sustainability Transitions Conference (IST) will discuss advances in the field of sustainability transformations. The conference will be organized by the Sustainability Transitions Research Network, in which both the Wuppertal Institute and Leuphana University of Lüneburg participate.

Description: Treating waste as a resource and the design of a circular economy have been identified as key approaches for resource efficiency. Despite ambitious targets, policies and instruments that would enable a transition from a conventional waste management to an integrated and comprehensive resource management are still missing. Moreover, this will require innovative policy mixes which do not only address different end-of-pipe approaches but integrate various resource efficiency aspects from product design to patterns of production and consumption. Based on the results of a project funded by the Seventh Framework Programme for Research and Technological Development named "POLFREE - Policy Options for a resource efficient economy", this paper addresses several aspects of the conceptualization of policy mixes with regard to waste as a specific resource efficiency challenge. The guiding research interest of this paper is the combination of policies necessary to create a full circular economy. In a first step, the present waste policy frameworks, institutions and existing incentives at national level are examined in order to disclose regulatory and policy gaps. Based on this, the second part of the paper describes and analyses specific waste-related resource efficiency instruments with regard to their potential impacts under the constraints of various barriers. Based on the assessment of the country analyses and the innovative instruments, the paper draws conclusions on waste policy mixes and political needs.

Description: A reduction in working hours is being considered to tackle issues associated with ecological sustainability, social equity and enhanced life satisfaction - a so-called triple dividend. With respect to an environmental dividend, the authors analyse the time use rebound effects of reducing working time. They explore how an increase in leisure time triggers a rearrangement of time and expenditure budgets, and thus the use of resources in private households. Does it hold true that time-intensive activities replace resource-intensive consumption when people have more discretionary time at their disposal? This study on environmental issues is complemented by introducing the parameters of voluntary social engagement and individual life satisfaction as potential co-benefits of rebound effects. In order to analyse the first dividend, a mixed methods approach is adopted, enabling two models of time use rebound effects to be applied. First, semi-standardised interviews reveal that environmentally ambiguous substitutions of activities occur following a reduction in working hours. Second, estimates for Germany from national surveys on time use and expenditure show composition effects of gains in leisure time and income loss. For the latter, we estimate the marginal propensity to consume and the marginal propensity to time use. The results show that time savings due to a reduction in working time trigger relevant rebound effects in terms of resource use. However, both the qualitative and quantitative findings put the rebound effects following a reduction in working time into perspective. Time use rebound effects lead to increased voluntary social engagement and greater life satisfaction, the second and third dividends.

Description: One of the factors decelerating a further diffusion of the carbon capture and storage (CCS) technology is the public's negative perception of early pilot or demonstration activities in Germany as well as in other countries. This study examined the public perception of CCS in more detail by looking into different options within the CCS chain, i.e. for the three elements capture, transport and storage. This was analyzed using an experimental approach, realized in an online survey with a representative German sample of 1830 citizens. Each participant evaluated one of 18 different CCS scenarios created using three types of CO2 source (industry, biomass, coal), two transport options (pipeline vs. no specification), and three storage possibilities (saline aquifer, depleted gas field, enhanced gas recovery (EGR)). Overall, we found that the ratings of CCS were neutral on average. However, if the CO2 is produced by a biomass power plant or industry, CCS is rated more positively than in a scenario with a coal-fired power plant. The specifications of transport and storage interacted with each other such that scenarios including EGR or a depleted gas field without mentioning a pipeline were evaluated better than storing it in a saline aquifer or a depleted gas field and mentioning a pipeline as means of transport. Exploratory regression analyses indicate the high relevance of the respective CO2 source in general as well as the perceived importance of this source for Germany.

Description: In order to make our lifestyles sustainable, changing our consumption patterns is fundamental. Hence, we need to better understand who the "consumers" are and to consider them as an active actor to directly engage for ensuring effective policies. In order to support a resource-light society, production and consumption need to be considered through an integrated system view; within this, consumers play an important role as co-acting subjects. Almost every activity in private life involves a form of consumption aimed at satisfying the subject's needs and often regarded through an economic lens. Sustainable development is not about abolishing private consumption, but rather about making it environmentally, socially and individually sustainable in its design, organization and realization, also involving ideas of simplicity or renunciation. In this paper, we will assess the status quo of the German and European debates on Consumer Research Policies and discuss the idea to link sustainability research and consumer research - where a strategic relation is currently missing. Within that discussion, an evidence-based and obligatory consumer research strategy in Germany and Europe would represent a significant improvement. A system view perspective is necessary to take into consideration the impressive amount of diversity, and to elaborate realistic economic and consumer policies. Therefore, we propose nine steps for understanding the role of the consumer in implementing sustainable development from a scientific and political perspective. The limitations of this paper are thus a result of the very diverse and often unclear policies and agendas produced by governments. The implementation of the proposed innovative research agenda for a future-orientated and sustainability-based consumer research is not free from challenges. Still, the paper suggests the first steps towards this direction. After a critical discussion of the current EU and German consumer and sustainability policies, nine differentiated and substantial ways to integrate and ameliorate them are proposed.

Description: To live a life of sufficiency in a consumerist culture may be one of the most ambitious experiments an individual could undertake. To investigate this challenge, we employed a social-practice approach. This article is based on 42 qualitative interviews asking respondents why and how they acted in a sufficient way within a Western infrastructure and culture. The results indicate that sufficiency-oriented people draw on particular meanings in everyday-life practices when adopting relevant resource-extensive actions. These understandings encompass an amalgam of environmentally friendly attitudes, positive social intentions, and/or personal commitments to thriftiness. We further identified a set of specific practices - including sharing, recycling, and reusing - as useful for the adoption of a sufficient lifestyle. For our respondents, many of these sufficiency practices occurred regularly in daily life and were rarely questioned. Using an additional survey, we show that these routines lead to less resource-intensive lifestyles and demonstrate how a small group of people has been able to habitually adopt sufficiency practices. However, the majority does not see a need for more frequent implementation of such routines because daily decision-making processes are widely focused on the consumption of products.
