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: 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: 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: 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: 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: 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: 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 Sino-German project "Low Carbon Future Cities" (LCFC) aims to develop a low carbon strategy for its Chinese pilot city Wuxi. The strategy primarily focuses on carbon mitigation, but also considers links with the issues of resource efficiency and adaption to climate change. This report written by Daniel Vallentin, Carmen Dienst and Chun Xia offers strategic examples of good practice and makes recommendations to Wuxi city government about the changes that key sectors can adopt in order to comply with its low carbon targets. The recommendations are based on scientific analyses which were undertaken earlier in the LCFC project.

Description: A cost-minimizing electricity market model was used to explore optimized infrastructures for the integration of renewable energies in interconnected North African power systems until 2030. The results show that the five countries Morocco, Algeria, Tunisia, Libya and Egypt could together achieve significant economic benefits, reaching up to EUR 3.4 billion, if they increase power system integration, build interconnectors and cooperate on joint utilization of their generation assets. Net electricity exports out of North Africa to Europe or Eastern Mediterranean regions, however, were not observed in the regime of integrated electricity markets until 2030, and could only be realized by much higher levels of renewable energy penetration than currently foreseen by North African governments.

Description: Another summit of change, known as Rio+20, has passed in summer 2012, nourishing the rumours of a green economy. Building up a green economy seems to be the all over recipe for different crises of capitalism, among them climate change and resource scarcity. Yet efficiency and consistency, as their main strategies, do not suffice to reach sustainable levels, as they cause rebound effects and keep stimulating economy growth. Obviously, there are limits to green growth, too. Can we conceive an economy, and respective economic institutions, that serve human needs and wealth without a built-in necessity to grow? What kind of political, mental, and individual changes does a sufficiency economy require? And what are perspectives and policies to actually start implementing it? Just before Rio +20 the symposium "Economy of Sufficiency", devoted to Wolfgang Sachs on the occasion of his 65th birthday in 2011, examined these questions in three dimensions. Accordingly this selection of contributions to the symposium follows the chapters "Wealth in diversity" (Ashok Khosla, Marianne Gronemeyer, Vandana Shiva), "Enjoyable limits" (Richard B. Norgaard, Tim Jackson) and "Creating commons" (Ezio Manzini, Silke Helfrich). The essays indicate the historical development of the ideas on a sufficiency economy. Wandering through discourses of sustainable development for several decades, the authors map the range of perspectives, practices as well as barriers and bridge them between cultures, agencies and schools.

Description: Our perception of design is changing, for design today is no longer concerned only with aesthetics. Now the key factors are interdisciplinary competence and approaches to problem solving. Both politicians as well as businesses recognise design's hybridity and increasingly implement it as a driver of sustainable development (see Chap. 2: Design as a Key Management Factor for Sustainability). But what exactly does "sustainability" mean? What does it mean in this specific context? People must make use of natural resources to meet their basic needs. In this process, resources are transferred into commercial circulation and usually transformed into products with a particular function. Yet the environment is limited and humanity uses more resources than the Earth can sustainably provide. It is time to rethink and generate the same usage while consuming fewer resources (see Chap. 3: Environmental Space - Challenging Transitions). Most countries have incorporated sustainability strategies into their political agendas in order to counteract the threats of climate change caused by the overuse of natural resources, high CO2 emissions, and other factors. The indicators for these strategies vary greatly from country to country (see Chap. 4: Sustainability - Challenges, Politics, Indicators). These indicators need to be taken into account if we are to successfully implement a product or service within a specific context. A concept can only be successful when country-specific indicators are taken into account and the societal context is incorporated into the plan right from the start. The goal is to develop services that support national sustainability targets in production and consumption systems (see Chap. 5: Managing Sustainable Development). When it comes to companies, these changes can simply be introduced in the form of services or products. In the end, it is the users who decide on the success or failure of innovative solutions by either integrating them into their daily lives or ignoring them. Solutions will only be integrated into users' lives when their role within the social framework remains unchallenged by behavioural transformations caused by use of the solution. In order for users to be able to adopt innovations, sustainable development must take place simultaneously on many different levels. These multi-levelled transitions allow for the transformation of society as a whole. Designers can act as agents of change by providing the needed innovations (see Chap. 6: Transition Requires Change Agents for Sustainability). If we are to develop suitable solutions and new approaches, the real needs have to be analysed at the beginning of the development process. New physical products, which frequently result in auxiliary products, are often developed without taking into account the overall context, whereas the development of service-orientated solutions is ignored. A physical product is not absolutely necessary. A service (which is naturally dependent on physical products) can usually fulfil the need just as well - or perhaps even better and at a lower cost – while using fewer or no resources (see Chap. 7: Needs & Services - An Approach). There are a variety of possible approaches to integrate sustainability into the design process (see Chap. 8: Design Process). Precisely which solution is "most or more sustainable" (this is dependent on the defined targets and the indicators used) is often not immediately obvious, and we must turn to a set of methods for a transparent and tangible assessment (see Chap. 9: Sustainability Assessment in Design - Overview and Integration of Methods).
