Intelligent Product Design
(2012)
The aim of this thesis is to generate reality-based hypotheses about the opportunities and obstacles that create the implementation of Cradle to Cradle for the companies Jules Clarysse NV and Steelcase Inc. It discusses further which marketing-mix is appropriate for Cradle to Cradle products. Therefore exploratory expert interviews have been conducted with both companies. The empirical part is introduced by a literature study. From marketing perspective, the Cradle to Cradle approach for product design is investigated while taking into account that academic literature categorizes the concept on the one hand as consistent sustainability strategy, on the other hand as sustainable design. Moreover, the broad use of the expression design, within the literature of the Cradle to Cradle founders, is analyzed. Here, Cradle to Cradle design is holding out the prospect of Triple Top Line growth, rather than meeting only the economic bottom line. In regard of aesthetics, Cradle to Cradle aspires diversity in contrast to prevailing principles of Functionalism and universal design solutions. The ‘hidden‘ design assignment of Cradle to Cradle, service design, is highlighted as sphere that should be progressed. All these considerations form the interview guideline. The interviews serve as reality check whether there result Triple Top Lines and new service models for the companies and explore how aesthetics and tools of the marketing-mix are handled in Cradle to Cradle practice.
Auf Grund der stetig wachsenden Menge an Daten gewinnt die automatische Datenanalyse durch Algorithmen zunehmend an Bedeutung. Im Speziellen trägt die Analyse von Texten ohne manuelles Zutun zu einer erheblichen Erleichterung der Extraktion von relevanten Informationen bei. Sprachliche Informationen können neben der Zuordnung zu Kategorien auf Regeln und Muster untersucht werden. Diese Art der Untersuchung fällt in den Bereich des Text Minings, und in der vorliegenden Arbeit geht es darum, eine qualitative Inhaltsanalyse zum Thema Nachhaltigkeit nachzuempfinden. Es soll geprüft werden, in wie weit automatisierte Verfahren in der Lage sind, Ergebnisse einer bereits bestehenden Untersuchung zu erzielen. In der Durchführung werden mit der Open Source-Software RapidMiner vier Prozesse erstellt, die darauf abzielen, Zeitungsartikel auf ihren Inhalt zu analysieren. Unter anderem werden eine Assoziationsanalyse und eine Klassifikation realisiert, deren Ziel es ist, den Kontext und die Verwendung des Begriffes der Nachhaltigkeit in den Medien zu untersuchen. Die vorliegende Studie will prüfen, ob automatisierten Methoden im Vergleich zu manuellen Verfahren hinreichende Ergebnisse liefern können, sodass die hiesigen Resultate an denen der zu Grunde gelegten Studie von Fischer und Haucke gemessen werden sollen. Die Ergebnisse zeigen, dass die Realisierung einer Inhaltsanalyse mit RapidMiner möglich ist und zu erheblichen Zeiteinsparungen gegenüber konventionellen Verfahren führt. Sie zeigen jedoch auch, dass sich die Minderung des Aufwandes in der Ergebnisqualität widerspiegelt und somit der alleinige Einsatz von Text Mining Verfahren zur Analyse von spezifischen Kontexten noch nicht ausreichend ist.
Die Verringerung des Material- und Ressourcenverbrauchs ist eine wesentliche Herausforderung nachhaltiger Entwicklung. Bislang standen und stehen politische Maßnahmen zur Energieeffizienz im Vordergrund. Maßnahmen zur Verbesserung der Materialeffizienz gewinnen jedoch verstärkt an Bedeutung. Der Erfolg oder Misserfolg politischer Instrumente im Umwelt- und Klimaschutzbereich wird maßgeblich davon abhängen, ob die Instrumente die Fähigkeit besitzen, eine Entkoppelung von Lebensqualität und Ressourcenverbrauch zu erzeugen. Insbesondere im Rahmen der Ökodesign-Richtlinie, aber auch anderer Instrumente der Europäischen Union, sind Ansatzpunkte zur politischen Gestaltung einer ressourcenleichten Langfristökonomie angelegt. Die Dissertation wird schwerpunktmäßig die Governance-Instrumente im Produktbereich der Europäischen Union behandeln. Die Dissertation folgt der Theorie, dass die Produkte der Industriegesellschaft einzeln mehr oder weniger harmlos, in ihrer Menge jedoch die Quelle fast aller Umweltprobleme sind. Zur Erstellung der Dissertation sieht das spezifische Methodendesign die Anwendung eines Kriterienkatalogs zur Bewertung der Steuerungsinstrumente für Langfristökonomie im Produktbereich vor. Darüber hinaus werden die Hauptakteure in Form von Interviews befragt.
Vor dem Hintergrund der steigenden Relevanz unternehmerischer Nachhaltigkeit beschäftigt sich die Wissenschaft verstärkt mit der Frage, welche Kompetenzen Entscheider benötigen, um Nachhaltigkeitsstrategien in Unternehmen erfolgreich umsetzen zu können. Denn entgegen der weit verbreiteten Meinung, dass bei der Umsetzung von Nachhaltigkeitsstrategien nur Win-win-Situationen auftreten, stoßen Manager bei der Integration ökologischer und sozialer Ziele ins Ziel-System der Unternehmen auf widersprüchliche ökonomische Rationalitäten (zwischen Effizienz und einzelnen/mehreren Dimensionen von Nachhaltigkeit) und inhärente Konflikte nachhaltiger Entwicklung (zwischen den Dimensionen sozial, ökologisch und ökonomisch). In der Folge entstehen vielfältige dilemmatische Entscheidungssituationen. Um Nachhaltigkeit langfristig in Unternehmen etablieren zu können, müssen die Dilemmata wahrgenommen und bewältigt werden. Voraussetzung hierfür sind vielfältige persönliche Kompetenzen bei den Entscheidern. Die vorliegende Arbeit untersucht die auftretenden dilemmatischen Entscheidungssituationen und den Umgang mit diesen. Darüber hinaus bestimmt sie die für die Dilemma-Bewältigung relevanten Kompetenzen sowie die zur Umsetzung von CS-Strategien erforderlichen Rahmenbedingungen im Unternehmen. Im Ergebnis wird ein Framework zu Dilemmata, den notwendigen Kompetenzen und den Rahmenbedingungen erarbeitet. Basierend darauf werden entsprechende Handlungsempfehlungen gegeben. Der erarbeitete CS-Dilemmata-Kompetenz-Atlas stellt praxisrelevantes Wissen für Unternehmen und Berater zur erfolgreicheren Umsetzung von Nachhaltigkeitsstrategien zur Verfügung.
This PhD thesis examines the connections between sustainability knowledge management (SKM) and sustainability management tools in small and medium-sized enterprises (SMEs). While previous literature has established that knowledge is essential for the application of sustainability management tools, the effects of such tools on knowledge management are under-researched in the sustainability context. Drawing on multiple academic papers and utilizing various research methods, including a systematic literature review, several quantitative surveys and a multiple case study approach, the thesis systematically examines how such tools can facilitate the identification, acquisition, conversion, application and retention of sustainability knowledge, and potentially lead to the improvement of SKM effectiveness in SMEs. Furthermore, it examines how support functions for sustainability management tools and SKM correspond with each other. The findings reveal that sustainability management tools facilitate the SKM processes (identification, acquisition, conversion, application and retention), and align with the support factors (e.g. top management support, shared vision, employee qualifications) to advance SKM in SMEs. Particularly, such tools permit the institutionalization of sustainability knowledge into the daily routines and practices in SMEs. Additionally, tools create a support structure for SKM, embedding and preserving sustainability knowledge in documents, policies, procedures and norms for an enterprise´s collective knowledge for sustainability management. The thesis concludes with complementing areas of future research and offers practical implications for SME management.

Sustainability and Justice: Conceptual Foundations and Cases in Biodiversity and Fishery Policy
(2014)
Sustainability aims at justice in a threefold sense: intragenerational justice, intergenerational justice, and justice towards nature. However, the justification, specific content and practical implications of justice claims and obligations in the sustainability context often remain underspecified. This dissertation therefore asks: How can the concept of justice be structured systematically? How can justice be specified in the context of sustainability? Which specific problems of justice arise in sustainability policy? And what are the respective contributions of (sustainability) economics and (sustainability) ethics? The five papers of this cumulative dissertation approach these issues from different angles, working at the conceptual level and at the level of cases from biodiversity and fishery policy. In Paper 1, a formal conceptual structure of justice is developed, which lists the conceptual elements of justice conceptions: the community of justice including claim holders and claim addressees, their claims (and corresponding obligations), the judicandum (that which is to be judged as just or unjust), the informational base for the assessment, the principles of justice, and on a more practical level, the instruments of justice. By specifying these conceptual elements of justice, it is possible to analyse and compare different conceptions of justice. In Paper 2, the normative dimension of sustainability is discussed in terms of justice. Based on the identification of certain core characteristics of the concept of sustainability, we determine the specific challenges of justice in the context of sustainability along the conceptual structure of justice (from Paper 1). Inter alia, we show that sustainability calls for the integration of justice claims in the relationships with contemporaries, future humans and nature in a non-ideal context characterized by uncertainty, systemic mediation and limits. Paper 3 addresses the contribution of economics to the assessment of trade-offs between intergenerational and intragenerational justice. Economic analysis can delineate the opportunity set of politics with respect to the two justice objectives and identify the opportunity cost of attaining one justice to a higher degree. While the two justices are primary normative objectives, the criterion of efficiency - when directed at the attainment of these justice objectives - has the status of a secondary normative objective. Paper 4 constitutes a case study, reconstructing the ´biopiracy´ debate from a justice perspective. The paper links to the so called Access and Benefit-Sharing framework of the Convention on Biological Diversity, and addresses the question, which problems of justice arise regarding the utilization of genetic resources and traditional knowledge, especially if associated with patenting. It is shown that the predominant perspective of justice-in-exchange is insufficient and therefore complementary conceptions, namely of distributive justice, corrective justice and structural justice have to be taken into account. Paper 5 empirically assesses the justice notions of stakeholders in the Newfoundland fishery, building on qualitative semi-structured interviews and a combination of inductive and deductive coding. A central result is that inshore fishers are seen as the main claim holders, with a claim to participate and being listened to, and the opportunity to make a living from the fishery. Recognition, participation and distribution are all important domains of justice in the context of the Newfoundland fishery. The paper also discusses the relationship between normative theorizing and empirical justice research. Overall, this thesis integrates ideal and non-ideal normative theorizing, economic analysis, empirical justice research and hints at institutional implementation in the debate on sustainability and justice.
The doctoral thesis deals with future challenges that the tourism market has to face on a global level. The problem is treated from different perspectives and with different thematic foci. Thematically, the thesis approaches both global changes in the tourism market and further developments of the research methodology. The methodological repertoire includes a Delphi survey in combination with a focus group, mobile ethnography in conjunction with participant observation and contextual interviews, and a quantitative online survey.
This PhD dissertation thesis aims to analyse and discuss how a company can interact with its supply chain stakeholders to facilitate the development of sustainable supply chains. The research is based on empirical and conceptual work and contributes to the field of corporate sustainability, supply chain management and its intersection. The thesis develops a conceptual framework to analyse four organisational spheres of interaction (inter, intra, supra and sub) in sustainable supply chain management (SSCM). Thereby, further insights into risk and opportunityoriented approaches of companies to SSCM are provided.
This dissertation concerns the question of how economics can contribute to the analysis of trade-offs between values (or normative objectives). The analysis is illustrated for the case of policies that pursue the goal of sustainability. Methodologically, this is done by reflecting economic concepts in light of philosophical theories and using generic models to analyze trade-offs between particular values. In sum, the work shows how economics can help in analyzing the factual relationships between values by clarifying the set of feasible acts and outcomes. The first paper of this cumulative dissertation concerns the question what a general definition of efficiency with respect to normative objective implies about relationships between two values. In order to conceptualize relationships between values carefully, the analysis distinguishes instrumental from intrinsic values and discusses the question whether there is one intrinsic value (value monism) or many intrinsic values (value pluralism). Next, a small economic model is used to show that there can be different relationships between values such as win-win relationships and trade-offs in value-efficient states if there are three or more values. Further, the distinction between Pareto-efficiency (based on individual preferences) and value-efficiency (which can also include non-preference values) is used to study relationships between values. The second paper uses the definition of sustainability as inter- and intragenerational justice to discuss the relationship between these two objectives. The general aim of this paper is to discuss what economic concepts can contribute to the discussion of tradeoffs between justices. For this, a syntax of the concept of justice is employed, different relationships between justices are defined and economic concepts such as scarcity, efficiency and opportunity costs are transferred to the justice context. One result from this analysis is that there must be a trade-off between these two justices in such respective efficient outcomes. The third paper concerns an intertemporal mechanism leading to the well-known equity-efficiency trade-off in an intergenerational setting. For this, two central characteristics of intergenerational policy making are taken into account: irreversibility and ignorance (or unawareness). A pertinent example is the irreversible use of fossil fuels before and after the discovery of the effect of CO2 emissions on climate change. The trade-off between Pareto-efficiency and intergenerational equity that results from these two characteristics is shown in a model with two non-overlapping generations which use a non-renewable resource. In the model there is initial unawareness about an intergenerational externality from resource use that is only discovered after the irreversible use of the resource. A central result of the paper is the trade-off between intergenerational equity and efficiency that emerges if initially unknown sustainability problems arise after irreversible policies have been enacted. The fourth paper concerns the question what the concept of merit goods can contribute to discussions of sustainability. For this, the history of the concept is discussed, then merit goods are defined and connected to the philosophical literature on different conceptions of well-being. In the next step different challenges and opportunities of merit good arguments are discussed for the sustainability context. For example, it becomes clear that merit good arguments concern conceptions of well-being and do not directly concern the aspect of intergenerational distribution in sustainability problems.
Business Models for Sustainability Innovation: Conceptual Foundations and the Case of Solar Energy
(2013)
This dissertation deals with the relationships between the increasingly discussed business model notion, sustainability innovation, and the business case for sustainability concept. The main purpose of this research is to identify and define the so far insufficiently studied theoretical interrelations between these concepts. To this end, according theoretical foundations are developed and combined with empirical studies on selected aspects of the solar photovoltaic industry. This industry is particularly suitable for research on sustainability innovation and business models because of its increasing maturity paired with public policy and market dynamics that lead to a variety of business model-related managerial and entrepreneurial business case challenges. The overarching research question is: How can business models support the commercialisation of sustainability innovations and thus contribute to business cases for sustainability? A theoretical and conceptual foundation is developed based on a systematic literature review on the role of business models in the context of technological, organisational, and social sustainability innovation. Further, the importance of business model innovation is discussed and linked to sustainability strategies and the business case for sustainability concept. These theoretical foundations are applied in an in-depth case study on BP Solar, the former solar photovoltaic subsidiary of British Petroleum. Moreover, because supportive public policies and the availability of financial capital are known to be the most important preconditions for commercial success with innovations such as solar photovoltaic technologies, the solar studies include a comparative multiple-case study on the public policies of China, Germany, and the USA as well as a conjoint experiment to explore debt capital investors’ preferences for different types of photovoltaic projects and business models. As a result, the main contribution of this work is the business models for sustainability innovation (BMfSI) framework. This framework is based on the idea that the business model is an artificial and social construct that fulfils different functions resulting from social interaction and their deliberate construction. The BMfSI framework emphasises the so-called mediating function, i.e. the iterative alignment of business model elements with company-internal and external requirements as well as with the specific characteristics of environmentally and socially beneficial innovations. Against this backdrop, it becomes clear that practically-oriented knowledge based on BMfSI research might provide new and effective ways to support the achievement of corporate sustainability.
In spite of growing interest in companies’ contribution to sustainable development, the implementation of corporate sustainability, i.e. the integration of environmental, social, and economic issues, is not well understood. This cumulative PhD thesis aims to answer the research question whether sustainability management is only a transitory management fashion, or whether an effective implementation is actually taking place. The thesis consists of five papers, which are either published in refereed academic journals, accepted to be published, or planned to be resubmitted. The papers analyze three important elements of the implementation of corporate sustainability: motivation (why?), organizational units (who?) and management tools (how?). Combining these three elements supplies a framework for discussing the implementation of corporate sustainability management. The results, which are mostly based on surveys of large German companies, reveal that companies predominantly manage corporate sustainability because they seek legitimacy, rather than a competitive advantage, and because they follow acknowledged standards, guidelines, or ratings (institutional isomorphism) – possibly out of uncertainty on how to best handle a concept so complex and novel. Public relations is the organizational unit engaging in sustainability management most strongly, whereas accounting, finance, and management control engage the least. Hence, corporate sustainability is currently not implemented as a crossfunctional approach. Yet, there is indication of a growing strategic relevance of corporate sustainability. This is also reflected in the awareness and application of sustainability management tools, which have been increasing continuously between 2002 and 2010 – especially in terms of integrative tools serving to balance environmental, social, and economic issues. Furthermore, market incentives are gaining in importance over time. The thesis relates these results to management fashion theory. Although there is some indication that sustainability management might in fact be a transitory fashion, an analysis over time reveals an ongoing development of the elements analyzed. Thereby, the thesis demonstrates that corporate sustainability management can be considered more than a management fashion. One implication of the analysis is that both companies and researchers are called upon to foster the implementation of corporate sustainability, with positive incentives, e.g. by markets and consumers, turning out to be promising starting points. As opposed to pressure and expectations by stakeholders, focusing on opportunities might be more suitable to induce actual change of processes, products, services, or even business models in companies. In conclusion, the author hopes to make a significant contribution to the discussion on the implementation of corporate sustainability and to stimulate the development of new theoretical approaches.
