    The concept of sustainability is continuously used in the environment, tourism, architecture, businesses and economy. In this study, the sustainability reports of public companies listed in BIST Sustainability Index are analysed under economic, environment and social categories identified by in the Global Reporting Initiative Reporting Guide. The aim of the study is to determine the disclosure practices of listed companies about sustainability issues. The sustainability reports of companies listed in BIST Sustainability Index are analysed with content analysis using Nvivo software programme and the result of the analysis are evaluated. The results of the study indicated that the most highlighted issues are as follows; in economic sustainability economic performance, in environmental sustainability products and services, in social sustainability employee and, health and safety issues. Further, the results of the regression analysis indicate that as the firm age and number of employees increase firms issue more comprehensive sustainability reports.

    Die Energiewende einschließlich der Substitution von russischem Erdgas ist eine große Herausforderung, welche fördernde Maßnahmen in vielen Bereichen des Energiesektors verlangt. Einer dieser Bereiche ist die Erzeugung von Biomethan aus häuslichen Küchenabfällen. Diese beinhalten vorwiegend Lebensmittelabfälle. Ein großes ungenutztes Potenzial zu deren Nutzung ist vorhanden. Bürger, Abfallentsorger und Politik können beitragen, dieses zu realisieren. The energy transition, including the substitution of Russian natural gas, is a major challenge that requires supportive measures in many areas of the energy sector. One of these areas is the production of biomethane from domestic kitchen waste. This mainly includes food waste. There is a large untapped potential for its use. Citizens, waste management companies and politicians can contribute to realise this.

    Authors: Iván López Pardo;

    For more than three decades, and with particular intensity in the 80’s, starts a process with no precedent on the global reflection driven by United Nations, and followed by the European Union, to address the issue of the planet’s sustainability and sustainable development as one of the great challenges that the XXI century face. The publication of the Brundtland Report (WCED, 1987) represents a milestone in the process offering a definition of sustainable development until today reference in the debate. In this article we review the positions and arguments for and those that are critical of this definition, to shed light on a concept in continuous state of definition at the same time pose the questions to be resolved in a debate no at all concluded.

    Authors: Becke, Guido; Warsewa, Günter;

    Im Verlauf der vergangenen Dekaden haben sich die sozio-ökonomischen wie auch die normativen und regulativen Grundlagen der Governance der Erwerbsarbeit in einer Weise verändert, die für das Handeln des einzelnen Menschen als Arbeitskraft und tätiges Subjekt neue Voraussetzungen schafft: Erwerbstätige gewinnen als unmittelbare individuelle Akteure in der Governance von Arbeit an Bedeutung. Die damit einhergehenden Prozesse der Flexibilisierung, Subjektivierung und Entgrenzung von Arbeit werden in den einschlägigen Debatten häufig und mit guten Gründen kritisch interpretiert, z. B. als erweiterte Landnahme oder Kolonialisierung von Subjektivität. Im Unterschied dazu wird in diesem Beitrag der Frage nachgegangen, ob und inwiefern sich hierdurch auch neue Chancen für eine nachhaltige(re) und sozialverträgliche(re) Gestaltung von Arbeit eröffnen. Insbesondere für hoch qualifizierte Beschäftigte als Individuen wie als ,neue‘ kollektive Akteure eröffnen sich hierbei Macht- und Möglichkeitsräume, ihre erweiterte Subjektperspektive zur Geltung zu bringen - mit womöglich durchaus ambivalenten Wirkungen auf Strukturen der Governance von Erwerbsarbeit und für betriebliche Arbeitsbeziehungen. Since the 1980s, governance structures of work and employment and their regulative and normative foundations have changed significantly. Due to reforms of the welfare state and the emergence of new production concepts, employees gained in significance as individual actors. The flexibilisation, disentanglement and subjectivisation of work confronted individual employees with enhanced psycho-social stress at work, new management strategies capitalising on their subjectivity for economic goals and taking more individual responsibility for their career and course of life. However, in this contribution options for a more sustainable design of work are explored that are closely linked with employees as individual actors. New production concepts are increasingly vulnerable to highly skilled individual employees in their self-regulation of work. This dependence can open up new options for highly skilled employees to claim socially accepted demands on sustainability in work organisations - however, with ambivalent side effects as the fragmentation of interests within workforces.

    Authors: Droste-Franke, Bert;

    Ziel dieser Arbeit ist es, ausgehend von vorhandenen Ansätzen, ein geschlossenes Konzept für die Berücksichtigung von Schäden durch die Schadstoffbelastung der Umwelt als Ergänzung von Volkswirtschaftlichen Gesamtrechnungen, sogenannten Umweltökonomischen Gesamtrechnungen (UGR), abzuleiten und dieses anhand der Umweltbelastung durch Luftschadstoffe und toxische Substanzen durchzuführen. Ausgehend von der Diskussion der beiden übergeordneten Ziele für eine umweltverträgliche wirtschaftliche Entwicklung, Effizienz und Nachhaltigkeit, werden zunächst Unterziele in Form von Prioritäten aufgestellt. Aus ihnen wird dann auf der Basis vorhandener Konzepte zu Indikatoren und UGR ein System von aggregierten Indikatoren entwickelt. Zur Berechnung der Indikatoren wird die Methodik des erweiterten Wirkungspfadansatzes vorgestellt. Neben der detaillierten Diskussion von Konzentrationswerten und Gesamtschäden für 1990 und 1998 erfolgt eine Analyse des zeitlichen und räumlichen Imports und Exports von Schäden sowie der Schäden, die durch unterschiedliche wirtschaftliche Aktivitäten in Deutschland entstehen. Zusätzlich werden mit Hilfe der Indikatoren die Nachhaltigkeit der wirtschaftlichen Entwicklung und die Effizienz definierter Umweltziele beispielhaft für das Jahr 2005 untersucht. Zur Demonstration der Anwendbarkeit der berechneten Ergebnisse im Rahmen von UGR werden unter anderem beispielhaft Korrekturen der Wirtschaftsindikatoren durchgeführt, wie sie von Projekten der Europäischen Kommission und Aktivitäten der Vereinten Nationen in diesem Bereich vorgeschlagen werden. Die ermittelten gesamten Schadenskosten für die Jahre 1990 und 1998 in den EU-15 Staaten und Deutschland betragen mehrere Prozent des jeweiligen Bruttoinlandsprodukts. Die Analyse des Jahres 2005 hat gezeigt, dass die politischen Ziele für 2010 größtenteils bereits in 2005 eingehalten werden können. In einigen Ländern sind effiziente Minderungen über die Einhaltung der Ziele hinaus möglich. The objective of this thesis is to develop a consistent concept for the consideration of impacts due to the pollution of the environment in order to supplement national accounting systems in a so-called green accounting framework and to apply the concept for air pollution and the dispersion of toxic substances. Based on a discussion of the two major aims for environmentally friendly economic development, efficiency and sustainability, first, subordinate aims are formulated as priorities. These are used together with a discussion of existing concepts for indicators and environmental accounting to develop a system of aggregated indicators. For the estimation of indicator values, the extended impact pathway approach is presented. Besides a detailed discussion of the concentration levels and damages for 1990 and 1998, an analysis of temporal and spatial import and export of damages as well as the amount of damages caused by different economic activities in Germany are assessed. Furthermore, the sustainability of the economic development and the efficiency of given environmental targets are analysed applying the indicators exemplarily for the year 2005. In order to demonstrate the applicability of the results within environmental accounts, among other things exemplary corrections of economic indicators are carried out following the proposals from European Commission projects and from activities of the United Nations in this area. The estimated total damage costs occurring in 1990 and 1998 within the EU-15 and Germany result to a few percent of the respective gross domestic product. The analysis of the year 2005 showed that in some countries political targets which were originally set for 2010 can already be reached in 2005. Furthermore, in some countries efficient reductions beyond the accomplishment of the targets are possible.

    Der vorliegende Beitrag beschäftigt sich mit der Bedeutung, die Nachhaltigkeitsmanagement für die anstehende weitere Reorganisation der Medienwirtschaft haben kann. Dazu wurde in zwei explorativen Studien einerseits die "interne" Selbstberichterstattung verschiedener Industrien in Bezug auf Sustainable Development Goals (SDGs) der Vereinten Nationen untersucht, andererseits die "externe" Medienberichterstattung zu diesem Thema. Beide Studien liefern interessante Einblicke, die sowohl in Bezug auf Nachhaltigkeitskommunikation als auch auf Nachhaltigkeitsmanagement interessante neue Erkenntnisse liefern. Besonders deutlich werden diesbezüglich zahlreiche Defizite bezogen auf die kritische Selbstreflexion gerade in der Medienindustrie. This article deals with the significance that sustainability management can have for the upcoming further reorganization of the media industry. To this end, two explorative studies were conducted to examine, on the one hand, the "internal" self-reporting of various industries with regard to Sustainable Development Goals (SDGs) of the United Nations and, on the other hand, the "external" media reporting on this topic. Both studies provide interesting insights that yield interesting new findings with regard to both sustainability communication and sustainability management. In this regard, numerous deficits related to critical self-reflection become particularly clear, especially in the media industry.

    Induziert durch Digitalisierung und Servitisierung bieten Unternehmen in zunehmendem Maße Systeme aus vernetzten mechatronischen Produkten, Software und Dienstleistungen an: sogenannte Smart Product Service Systems (Smart PSS). Zur Erfüllung der Sustainability Development Goals der Vereinten Nationen, insbesondere des Ziels 9 „nachhaltiger Konsum und Produktion“, müssen diese Systeme gemäß dem Leitbild einer Circular Economy (CE) gestaltet werden. Smart-circular PSS verfolgen nachhaltige Geschäftsmodelle und verstärken Strategien der CE durch datengetriebene Funktionen. Die Entwicklung dieser Systeme stellt Unternehmen vor große Herausforderungen. Ungeklärt ist bislang, wie Teams bei der Entwicklung von Smart-circular PSS sachgerecht methodisch unterstützt werden können. Diese Arbeit begegnet diesen Beobachtungen mit der Forschungshypothese, dass sich Systemarchitekturen von Smart-circular PSS durch geeignete Methoden des Modellbasierten Systems Engineerings (MBSE) so entwerfen lassen, dass die Systeme effektiv und effizient zu einer CE beitragen. Zu ihrer Verifizierung wurde als übergeordneter Forschungsansatz die Design Research Methodology (DRM) angewendet. Zunächst erfolgte die Forschungsklärung mithilfe von Expert*innenworkshops sowie durch eine MBSE-Reifegradanalyse in einem industriellen Unternehmen. Die hier identifizierten Handlungsfelder wurden mittels Systematischen Literaturanalysen (SLRs) abgesichert und ausgewählt. Aufbauend auf den gewonnenen Erkenntnissen wurde die Methodik zur Definition von Smart-circular PSS-Systemarchitekturen (MESSIAH) entwickelt, die Entwicklungsteams bei der Konzeptionierung von Smart-circular PSS unterstützt. Die Methode beinhaltet eine Modellierungsgenerik, eine gerichtete Methode sowie einen Baukasten zum schnellen Prototypisieren von Services. MESSIAH wurde mithilfe einer Comprehensive Descrip-tive Study anhand von fünf Studien evaluiert. Die Forschungshypothese konnte im Rahmen der Evaluierung verifiziert werden. Somit zeigt diese Arbeit erstmals Wege auf, wie Strategien der CE mithilfe des MBSE bei der Entwicklung von Smart-circular PSS Systemarchitekturen berücksichtigt werden können. MESSIAH ermöglicht die Modellierung einer interdisziplinären Systemarchitektur, die mechatronische Produkte, Software und Dienstleistungen integriert. Zur Modellierung von CE-relevanten Services wurden zwei neue prozessorientierte Modelltypen erfolgreich mit bestehenden Modellierungstechniken des MBSE kombiniert. Durch die Evaluierungsstudien konnte ein zufriedenstellender Stand der Akzeptanz und wahrgenommenen Nützlichkeit der Methodik nachgewiesen werden. Allerdings wurden Verbesserungspotentiale hinsichtlich ihrer Benutzbarkeit festgestellt. In weiterer For-schung wird es vonnöten sein, die Qualität und die Quantität der Anwendungsvalidierungen zu erhöhen. Zu diesem Zweck wird die Durchführung von Langzeitstudien sowie Anwendungen an industriellen Systemen in einem weiteren Einsatzspektrum und in weiteren Branchen empfohlen. In response to calls for digitization and servitization, businesses increasingly offer complex systems consisting of connected mechatronic products, software elements and services: so-called Smart Product-Service-Systems (Smart PSS). In order to meet the United Nations Sustainability Development Goals and in particular Goal 9 "Sustainable Consumption and Production", these systems must be compatible with the tenets of a Circular Economy (CE). The development of these systems presents businesses with major challenges. It remains unclear how engineering teams can be supported methodologically in developing Smart-circular PSS. This dissertation meets these challenges with the research hypothesis that suitable methods of Model-based Systems Engineering (MBSE) can aid in the development of Smart-circular PSS architectures, which effectively and efficiently contribute to a CE. The investigation applies Design Research Methodology (DRM) as an overarching research approach for hypothesis verification. Initially, expert workshops and an MBSE maturity analysis in an industrial enterprise served to clarify the research objective. Systematic Literature Reviews (SLRs) validated and detailed the fields of action identified. Based on the findings, the Methodology for Smart-circular PSS Architecture Definition (MESSIAH) was developed, which supports development teams in the design of Smart-circular PSS. The method includes a modeling framework, a method and a construction kit for prototyping services. MESSIAH was evaluated by means of a Comprehensive Descriptive Study based on five evaluation studies. The evaluation verified the research hypothesis. Consequently, this research explores how the development of Smart PSS with the help of MBSE can be useful to CE-strategies. MESSIAH enabled the management of system complexity by using an interdisciplinary system architecture that integrates the development of mechatronic products, software and services. In order to de-velop CE-relevant services, two new types of models were successfully integrated into existing modelling techniques of MBSE. User studies indicated a satisfactory level of user acceptance and perceived usefulness of the methodology, but also served to identify potential for improve-ment with regard to its ease of use. In further research it will be necessary to increase the quality and quantity of application validations in further application scenarios and other industry branches. For this purpose, the dissertation recommends long-term studies and applications on further industrial systems.

    With the programme “Subject-related Partnerships with Universities in Developing Countries” the German Academic Exchange Service (DAAD) supports German universities in structure-building cooperation projects with partners in countries of the South. The German-foreign cooperation aims at giving both sides new impulses in teaching and the formation of new structures at the foreign university. Since 2009 the Institute for Environmental and Sustainability Communication at the Leuphana University of Lüneburg has implemented partnership projects with universities in Ecuador and Peru sponsored by the DAAD. The scientific evaluation of the project “Teaching and Learning Sustainability” with the Universidad Técnica del Norte (UTN), Ecuador, shows that the project contributes to the integration of the concept of sustainable development in teaching, research and administration at the UTN and that it opens opportunities for global learning for all participants. However, also challenges of North-South cooperation in higher education become apparent. (DIPF/Orig.) Mit dem Förderprogramm „Fachbezogene Partnerschaften mit Hochschulen in Entwicklungsländern“ unterstützt der Deutsche Akademische Austauschdienst (DAAD) deutsche Hochschulen bei strukturbildenden Kooperationsvorhaben mit Partnern in Ländern des Südens.

    Authors: Zhang, Yajin;

    Seit dem Beginn des 20. Jahrhunderts ist die Entwicklung Neuer Städte ein sehr wichtiges Element der modernen Städtebautheorie und Städtebaupraxis. Auf der materiellen „Ebene“ haben die Neuen Städte mit der Unterstützung der Öffentlichen Hand eine hohe „Quantität“ der Massenbebauung ermöglicht, sie dient unterschiedlichen Entwicklungszielen auf der Ebene der Kommune, der Region und des Landes, ebenso wie der Behebung der Wohnungsnot, der Entlastung der Metropolen oder der Förderung von Wirtschaftszentren. Die Neue Stadt hat eine besondere natürliche „Qualität“, die regionale, gut eingebundene Lage der Neuen Städte, ihre Einbindung in die natürliche Umwelt und das hohe Niveau ihrer Infrastruktur und ihrer öffentlichen Einrichtungen. Der Bau Neuer Städte erweist sich geschichtlich immer als eines der wichtigsten Mittel zur Stärkung der kommunalen und regionalen Kompetenzkraft; deshalb wurden auch immer dann noch Neue Stadt-Quartiere gebaut, wenn die Wohnungsnot nicht mehr vorhanden war. Die Entwicklung der Neuen Städte ist auch ein ständiger Zeuge der Entwicklung der Städtebautheorien und von diesen im Positiven wie im Negativen ständig beeinflusst. Die Planung ganzer Neuer Städte ist eine der kompliziertesten Aufgaben des Städtebaus - die Realisierung ungeprüfter Innovationen, das schnelle Planungs- und Entwicklungstempo, die aus finanziellen Gründen oft schwach ausgeprägten öffentlichen Einrichtungen oder die Folgen einseitiger Sozialpolitik verstärken die Schwierigkeiten bei der Entwicklung einer Neuen Stadt. Das einseitige Übergewicht quantitativer Maßstäbe erzeugt eine Diskrepanz zwischen Qualität und Quantität. Die Neuen Städte als Aufgabe Das Thema der - so definierten - „Neuen Städte“ ist heute sowohl wegen der Erneuerungsbedürfnisse der „alten“ Neuen Städte, der Entwicklungsbedürfnisse der Neuen Stadt-Quartiere, sowohl in Europa, wie auch in der globalen Neue Stadt-Entwicklung von höchster Aktualität. Als ein Spiegel der modernen Städtebau-Entwicklung ist die Neue Stadt sowohl auf der Ebene der Forschung als auch der Praxis von sehr hoher Bedeutung, jedoch gibt es seit den 1970er Jahren zu dem Thema „Neue Stadt“ kaum noch Forschungsaktivitäten. In China ist die „Neue Stadt“, bereits in der Historie, immer ein wichtiges Element des Stadtentwicklungsmodells gewesen. Die Stadt ist der klar definierte Träger der speziellen Bedeutung: von der Gesellschaftsordnung über die Philosophie bis insbesondere zu der Politik. Die einschneidende Veränderung der chinesischen Kultur am Ende des Kaiserreiches - zu Beginn des 20. Jahrhunderts - führte zu einer Philosophie, welche die „westliche Kultur“ in Bezug auf Funktion und Form aufnimmt, jedoch die chinesische lokale Kultur als Seele - der Stadt - begreift. Diese Art der Trennung - der Stadtauffassung - beeinflusst die Philosophie der chinesischen Stadtentwicklung noch heute. Die 80er Jahre des 20. Jahrhunderts waren der Anfang der Ausbreitung der chinesischen Verstädterung. In diesem rasanten Verstädterungsprozess haben nicht nur die Metropolen, sondern auch die chinesischen Mittel- und Kleinstädte, die Neue Stadt als das wichtigste Instrument der Stadtentwicklung gewählt. Jedoch ist aufgrund des begrenzten Überblickes und des mangelhaften Wissensstandes, insbesondere für eine chinesische Neue Stadt heute, deren Grundlage in materieller sowie immaterieller Hinsicht schwach. Leitgedanken der Planung Neuer Städte Aus der hier dargestellten Forschungsarbeit lassen sich, als erster Teil der Arbeitsergebnisse, folgende Erfahrungen zusammenfassen: - Soziale Stadtgesellschaft: In der Planung einer Neuen Stadt ist nicht die Stadt selbst das wichtigste Entwicklungsziel, sondern vielmehr die Gesellschaft der Neuen Stadt. - Harmonische Humanität: Der eigentliche Zweck einer Neuen Stadt ist die harmonische Humanität, - d.h. die Schaffung eines Gleichgewichts der oft polaren Bedürfnisse der Menschen. - Global-historisches Stadtbild: Das Stadtbild, der Spiegel der immateriellen Qualität einer „Neuen Stadt“, ist deshalb ebenso wichtig wie die materielle Stadt und ihre funktionale Effektivität. Die Identität des Stadtbildes beruht auf einer Synthese von moderner, globaler Weltkultur und historischer, regionaler Kultur. Modell einer nachhaltigen Neue Stadt-Planung Aus diesem ergeben sich die Anforderungen an den Sinn, Inhalt und Ablauf der Planung einer Neuen Stadt sowie an den Hintergrund der Gründungsinitiative, die Gruppe der Initiatoren, den Planungsinhalt, den Arbeitsprozess, allgemeine Grundsätze des Städtebaus und der Planung Neuer Städte. Als Beispiele werden europäische und chinesische Neue Städte vor dem Hintergrund der Ansprüche der Menschen an ihre physische und psychische Umwelt analysiert. Since the beginning of the 20th Century, the development of new towns is a very important element of the modern urban planning theory and the practice of urban development. On a physical level, the new towns have a special “quantity” of large buildings and rich developed areas with support from the public sector. They serve different development objectives at local, regional and national levels, such as solving the housing shortage, the discharge of the metropolis, or the promotion of economic centers. The new city also has special natural born qualities, the location of the new towns, their integration into the natural environment, its high level of infrastructure and new public facilities. Historically, the establishment of new cities always proves to be one of the most important means to strengthen local and regional expertise; therefore nowadays more and more new city blocks are built, even when the housing shortage has no longer existed. The development of new towns is like witnessing the evolution of urban planning theories, from those in both the positive and negative influences. The planning of complete new towns is already one of the most complicated tasks of urban planning - it is believed that the problems are worsened by the realization of untested innovations, the rapid pace of development and planning, financial reasons, weak public facilities, or a one-sided social policy. The unilateral emphasis on the quantity causes discrepancies between quality and quantity. The new towns as a task The topic of the – so called – “new towns” requirements today both concern the renovation needs of the “old” new towns and the development needs of new communities in Europe and the global new urban development, from the most up-to-date. The new town as a mirror of modern urban development is highly meaningful from both a research and a practical level. However the research on the topic "New Town" has been almost complete since the 1970's. In China, the "new town" had historically been an important element of the urban development model. The town is a well-defined carrier having special importance to the social order and particularly in philosophy and politics too. The dramatic change in the Chinese culture at the end of the empire - at the beginning of the 20th Century - has led to a philosophy that accommodates the western culture in both form and functionalities, but the local Chinese culture as a soul – can be seen in the towns. This kind of separation - the town view - influenced the philosophy of the Chinese town development today. The 1980s was the beginning of the spread of Chinese urbanization. In this rapid urbanization process, it was not only the metropolises, but also the Chinese medium and small towns that chose the "new towns" as the most important characteristic of urban development. Nowadays, because of a limited overview and insufficient knowledge, the foundation of Chinese new towns seems to be weak materially and immaterially. Guide principle in planning new towns As the first part of the results of this paper, the following experience is summarized: - Social urban society: To plan a new town, the most important thing is not the town per se, but the society in a new town. - Harmonic Humanity: The real purpose of a New Town is a harmonious humanity – it means a human living environment - that is capable of all material and immaterial needs of all classes and all levels of generation to meet the prospective city inhabitant. - Global historical town: the town, a mirror of the immaterial qualities of a "New Town", is just as important as the physical town and its functional effectiveness. The identity of the cityscape is based on a synthesis of modern, global culture and historical, regional culture. Model of a sustainable new town planning Therefore the basis of a theoretical model for a new city can be determined. Things such as the background to the start-up initiative, the group of initiators, the content of planning, the work process and the general principles of urban design and planning of new towns. As an example, a new Chinese "New Towns" is analyzed with the context of requirements from a Chinese family on their physical and psychological environment.

    Authors: Bruchof, David;

    Vor dem Hintergrund allgemeiner energie- und klimapolitischer Ziele wie der Verringerung der Ölabhängigkeit oder der Reduktion der Treibhausgasemissionen werden hohe Erwartungen an den Einsatz alternativer Kraftstoffe und Antriebe im Verkehr geknüpft. Unsicherheiten bestehen jedoch in der Frage, welche Kraftstoff-Antriebskombinationen sowohl in ökonomischer als auch in ökologischer Hinsicht die besten Voraussetzungen mitbringen, um den gestellten Zielsetzungen gerecht zu werden. Die Beantwortung dieser Frage kann nicht durch eine isolierte Betrachtung des Verkehrssektors erfolgen, sondern erfordert zusätzlich die Berücksichtigung von Wechselbeziehungen zwischen dem Verkehrssektor und anderen Bereichen des Energiesystems. So müssen beispielsweise die während der Bereitstellung alternativer Kraftstoffe (Well-to-Tank) entstehenden Treibhausgasemissionen oder alternative Verwertungsmöglichkeiten für zur Kraftstoffbereitstellung eingesetzte Energieträger, wie z. B. Biomasse, in die Bewertung einfließen. Gerade im Hinblick auf ihren möglichen Beitrag zum Klimaschutz stehen verkehrspolitische Maßnahmen zur Senkung des Treibhausgasausstoßes zudem nicht nur untereinander sondern auch mit Vermeidungsoptionen in anderen Sektoren des Energiesystems im Wettbewerb. Das Ziel dieser Arbeit besteht daher darin, die mögliche Rolle alternativer Kraftstoffe und Antriebe als Teil einer energiewirtschaftlichen Verkehrsstrategie zu analysieren, welche darauf ausgerichtet ist, im Einklang mit allgemeinen energie- und klimapolitischen Zielen eine umweltverträgliche, bezahlbare und versorgungssichere Mobilitätsbereitstellung in Deutschland und der EU-27 zu gewährleisten. Dazu werden zunächst im Rahmen einer Technologiecharakterisierung unterschiedliche alternative Kraftstoffpfade und Antriebskonzepte bezüglich ihrer derzeitigen und zukünftigen technischen, ökonomischen und ökologischen Eigenschaften bis zum Jahr 2050 analysiert. Die Ergebnisse dieser Technologiecharakterisierung werden anschließend zusammengeführt, indem ausgewählte Kraftstoff-Antriebskombinationen in einem Well-to-Wheel Vergleich hinsichtlich ihrer Mobilitätskosten, Treibhausgasemissionen und Treibhausgasvermeidungskosten gegenüber konventionellen Antrieben auf Mineralölbasis bewertet werden. Aufbauend auf den Ergebnissen der Technikanalyse wird im Anschluss die mögliche Bedeutung alternativer Kraftstoffe und Antriebe in Deutschland und Europa bis zum Jahr 2050 unter Berücksichtigung der energie- und klimapolitischen Rahmenbedingungen sowie in Abhängigkeit von den technischen Entwicklungsfortschritten untersucht. Dazu wird eine modellgestützte Systemanalyse unter Anwendung des Energiesystemmodells TIMES PanEU durchgeführt, welche es ermöglicht, die genannten Wechselbeziehungen zwischen Verkehrssektor und restlichem Energiesystem zu erfassen und bei der quantitativen Bewertung der Potenziale alternativer Kraftstoffe und Antriebe einzubeziehen. Im Ergebnis zeigt sich, dass vor allem Biokraftstoffe und elektrische Antriebskonzepte, wie Batterie betriebene Elektrofahrzeuge und Plug-in-Hybridfahrzeuge, bei ambitionierten Klimaschutzvorgaben oder eingeschränkter Verfügbarkeit konventioneller Kraftstoffe langfristig (nach 2030) in zunehmendem Maße eine wichtige Rolle im Verkehrssektor spielen. Alternative fuels and power trains are often appreciated as possible options for the achievement of general targets from energy and climate policy like the decrease of oil dependency or the reduction of greenhouse gas emissions. However, uncertainties exist, which combinations of fuels and power trains are suited best from an economic and ecological point of view to cope with the existing requests. This question cannot be answered by an isolated analysis of the transport sector. Instead, an additional consideration of interdependencies among the transport sector and other sectors of the energy system is required. This comprises for example the inclusion of well-to-tank greenhouse gas emissions that occur during the preparation of alternative fuels or other possible options for the utilization of energy carriers that are needed as feedstock for alternative fuel production (e. g. biomass). Especially with regard to climate protection, measures for greenhouse gas mitigation in the transport sector are not only in competition among each other but also with measures in other sectors of the energy system. The intention of this study therefore is to analyze the potential role of alternative fuels and power trains as part of an energy economic transport strategy, which in the context of general targets from energy and climate policy aims at an environmentally friendly, affordable and secure mobility in Germany and the EU-27. The study starts with a characterization of the technical, economic and ecological properties of different pathways for alternative fuel production and alternative propulsion concepts, looking at the state of the art and the development until 2050. The results of this analysis are then used for a well-to-wheel assessment of selected combinations of alternative fuels and power trains regarding mobility costs, greenhouse gas emissions and greenhouse gas abatement costs related to conventional oil based vehicles. Based on the outcome of the previous investigation, the potential role of alternative fuels and power trains in Germany and the EU-27 as a whole until 2050 is evaluated, depending on the energy and climate policy framework and on the further technical development. For that purpose a model based analysis with the energy system model TIMES PanEU is applied, which allows to cover also the mentioned interconnections between the transport sector and the rest of the energy system. As a result of the analysis, especially biofuels and electric power trains like battery electric and plug-in hybrid electric vehicles prove to be important alternative technological options for the transport sector in the long run (after 2030), if ambitious climate targets are set or if the availability of conventional oil based fuels is limited.

    The concept of sustainability is continuously used in the environment, tourism, architecture, businesses and economy. In this study, the sustainability reports of public companies listed in BIST Sustainability Index are analysed under economic, environment and social categories identified by in the Global Reporting Initiative Reporting Guide. The aim of the study is to determine the disclosure practices of listed companies about sustainability issues. The sustainability reports of companies listed in BIST Sustainability Index are analysed with content analysis using Nvivo software programme and the result of the analysis are evaluated. The results of the study indicated that the most highlighted issues are as follows; in economic sustainability economic performance, in environmental sustainability products and services, in social sustainability employee and, health and safety issues. Further, the results of the regression analysis indicate that as the firm age and number of employees increase firms issue more comprehensive sustainability reports.

    Die Energiewende einschließlich der Substitution von russischem Erdgas ist eine große Herausforderung, welche fördernde Maßnahmen in vielen Bereichen des Energiesektors verlangt. Einer dieser Bereiche ist die Erzeugung von Biomethan aus häuslichen Küchenabfällen. Diese beinhalten vorwiegend Lebensmittelabfälle. Ein großes ungenutztes Potenzial zu deren Nutzung ist vorhanden. Bürger, Abfallentsorger und Politik können beitragen, dieses zu realisieren. The energy transition, including the substitution of Russian natural gas, is a major challenge that requires supportive measures in many areas of the energy sector. One of these areas is the production of biomethane from domestic kitchen waste. This mainly includes food waste. There is a large untapped potential for its use. Citizens, waste management companies and politicians can contribute to realise this.

    Authors: Iván López Pardo;

    For more than three decades, and with particular intensity in the 80’s, starts a process with no precedent on the global reflection driven by United Nations, and followed by the European Union, to address the issue of the planet’s sustainability and sustainable development as one of the great challenges that the XXI century face. The publication of the Brundtland Report (WCED, 1987) represents a milestone in the process offering a definition of sustainable development until today reference in the debate. In this article we review the positions and arguments for and those that are critical of this definition, to shed light on a concept in continuous state of definition at the same time pose the questions to be resolved in a debate no at all concluded.

    Authors: Becke, Guido; Warsewa, Günter;

    Im Verlauf der vergangenen Dekaden haben sich die sozio-ökonomischen wie auch die normativen und regulativen Grundlagen der Governance der Erwerbsarbeit in einer Weise verändert, die für das Handeln des einzelnen Menschen als Arbeitskraft und tätiges Subjekt neue Voraussetzungen schafft: Erwerbstätige gewinnen als unmittelbare individuelle Akteure in der Governance von Arbeit an Bedeutung. Die damit einhergehenden Prozesse der Flexibilisierung, Subjektivierung und Entgrenzung von Arbeit werden in den einschlägigen Debatten häufig und mit guten Gründen kritisch interpretiert, z. B. als erweiterte Landnahme oder Kolonialisierung von Subjektivität. Im Unterschied dazu wird in diesem Beitrag der Frage nachgegangen, ob und inwiefern sich hierdurch auch neue Chancen für eine nachhaltige(re) und sozialverträgliche(re) Gestaltung von Arbeit eröffnen. Insbesondere für hoch qualifizierte Beschäftigte als Individuen wie als ,neue‘ kollektive Akteure eröffnen sich hierbei Macht- und Möglichkeitsräume, ihre erweiterte Subjektperspektive zur Geltung zu bringen - mit womöglich durchaus ambivalenten Wirkungen auf Strukturen der Governance von Erwerbsarbeit und für betriebliche Arbeitsbeziehungen. Since the 1980s, governance structures of work and employment and their regulative and normative foundations have changed significantly. Due to reforms of the welfare state and the emergence of new production concepts, employees gained in significance as individual actors. The flexibilisation, disentanglement and subjectivisation of work confronted individual employees with enhanced psycho-social stress at work, new management strategies capitalising on their subjectivity for economic goals and taking more individual responsibility for their career and course of life. However, in this contribution options for a more sustainable design of work are explored that are closely linked with employees as individual actors. New production concepts are increasingly vulnerable to highly skilled individual employees in their self-regulation of work. This dependence can open up new options for highly skilled employees to claim socially accepted demands on sustainability in work organisations - however, with ambivalent side effects as the fragmentation of interests within workforces.

    Authors: Droste-Franke, Bert;

    Ziel dieser Arbeit ist es, ausgehend von vorhandenen Ansätzen, ein geschlossenes Konzept für die Berücksichtigung von Schäden durch die Schadstoffbelastung der Umwelt als Ergänzung von Volkswirtschaftlichen Gesamtrechnungen, sogenannten Umweltökonomischen Gesamtrechnungen (UGR), abzuleiten und dieses anhand der Umweltbelastung durch Luftschadstoffe und toxische Substanzen durchzuführen. Ausgehend von der Diskussion der beiden übergeordneten Ziele für eine umweltverträgliche wirtschaftliche Entwicklung, Effizienz und Nachhaltigkeit, werden zunächst Unterziele in Form von Prioritäten aufgestellt. Aus ihnen wird dann auf der Basis vorhandener Konzepte zu Indikatoren und UGR ein System von aggregierten Indikatoren entwickelt. Zur Berechnung der Indikatoren wird die Methodik des erweiterten Wirkungspfadansatzes vorgestellt. Neben der detaillierten Diskussion von Konzentrationswerten und Gesamtschäden für 1990 und 1998 erfolgt eine Analyse des zeitlichen und räumlichen Imports und Exports von Schäden sowie der Schäden, die durch unterschiedliche wirtschaftliche Aktivitäten in Deutschland entstehen. Zusätzlich werden mit Hilfe der Indikatoren die Nachhaltigkeit der wirtschaftlichen Entwicklung und die Effizienz definierter Umweltziele beispielhaft für das Jahr 2005 untersucht. Zur Demonstration der Anwendbarkeit der berechneten Ergebnisse im Rahmen von UGR werden unter anderem beispielhaft Korrekturen der Wirtschaftsindikatoren durchgeführt, wie sie von Projekten der Europäischen Kommission und Aktivitäten der Vereinten Nationen in diesem Bereich vorgeschlagen werden. Die ermittelten gesamten Schadenskosten für die Jahre 1990 und 1998 in den EU-15 Staaten und Deutschland betragen mehrere Prozent des jeweiligen Bruttoinlandsprodukts. Die Analyse des Jahres 2005 hat gezeigt, dass die politischen Ziele für 2010 größtenteils bereits in 2005 eingehalten werden können. In einigen Ländern sind effiziente Minderungen über die Einhaltung der Ziele hinaus möglich. The objective of this thesis is to develop a consistent concept for the consideration of impacts due to the pollution of the environment in order to supplement national accounting systems in a so-called green accounting framework and to apply the concept for air pollution and the dispersion of toxic substances. Based on a discussion of the two major aims for environmentally friendly economic development, efficiency and sustainability, first, subordinate aims are formulated as priorities. These are used together with a discussion of existing concepts for indicators and environmental accounting to develop a system of aggregated indicators. For the estimation of indicator values, the extended impact pathway approach is presented. Besides a detailed discussion of the concentration levels and damages for 1990 and 1998, an analysis of temporal and spatial import and export of damages as well as the amount of damages caused by different economic activities in Germany are assessed. Furthermore, the sustainability of the economic development and the efficiency of given environmental targets are analysed applying the indicators exemplarily for the year 2005. In order to demonstrate the applicability of the results within environmental accounts, among other things exemplary corrections of economic indicators are carried out following the proposals from European Commission projects and from activities of the United Nations in this area. The estimated total damage costs occurring in 1990 and 1998 within the EU-15 and Germany result to a few percent of the respective gross domestic product. The analysis of the year 2005 showed that in some countries political targets which were originally set for 2010 can already be reached in 2005. Furthermore, in some countries efficient reductions beyond the accomplishment of the targets are possible.

    Der vorliegende Beitrag beschäftigt sich mit der Bedeutung, die Nachhaltigkeitsmanagement für die anstehende weitere Reorganisation der Medienwirtschaft haben kann. Dazu wurde in zwei explorativen Studien einerseits die "interne" Selbstberichterstattung verschiedener Industrien in Bezug auf Sustainable Development Goals (SDGs) der Vereinten Nationen untersucht, andererseits die "externe" Medienberichterstattung zu diesem Thema. Beide Studien liefern interessante Einblicke, die sowohl in Bezug auf Nachhaltigkeitskommunikation als auch auf Nachhaltigkeitsmanagement interessante neue Erkenntnisse liefern. Besonders deutlich werden diesbezüglich zahlreiche Defizite bezogen auf die kritische Selbstreflexion gerade in der Medienindustrie. This article deals with the significance that sustainability management can have for the upcoming further reorganization of the media industry. To this end, two explorative studies were conducted to examine, on the one hand, the "internal" self-reporting of various industries with regard to Sustainable Development Goals (SDGs) of the United Nations and, on the other hand, the "external" media reporting on this topic. Both studies provide interesting insights that yield interesting new findings with regard to both sustainability communication and sustainability management. In this regard, numerous deficits related to critical self-reflection become particularly clear, especially in the media industry.

    Induziert durch Digitalisierung und Servitisierung bieten Unternehmen in zunehmendem Maße Systeme aus vernetzten mechatronischen Produkten, Software und Dienstleistungen an: sogenannte Smart Product Service Systems (Smart PSS). Zur Erfüllung der Sustainability Development Goals der Vereinten Nationen, insbesondere des Ziels 9 „nachhaltiger Konsum und Produktion“, müssen diese Systeme gemäß dem Leitbild einer Circular Economy (CE) gestaltet werden. Smart-circular PSS verfolgen nachhaltige Geschäftsmodelle und verstärken Strategien der CE durch datengetriebene Funktionen. Die Entwicklung dieser Systeme stellt Unternehmen vor große Herausforderungen. Ungeklärt ist bislang, wie Teams bei der Entwicklung von Smart-circular PSS sachgerecht methodisch unterstützt werden können. Diese Arbeit begegnet diesen Beobachtungen mit der Forschungshypothese, dass sich Systemarchitekturen von Smart-circular PSS durch geeignete Methoden des Modellbasierten Systems Engineerings (MBSE) so entwerfen lassen, dass die Systeme effektiv und effizient zu einer CE beitragen. Zu ihrer Verifizierung wurde als übergeordneter Forschungsansatz die Design Research Methodology (DRM) angewendet. Zunächst erfolgte die Forschungsklärung mithilfe von Expert*innenworkshops sowie durch eine MBSE-Reifegradanalyse in einem industriellen Unternehmen. Die hier identifizierten Handlungsfelder wurden mittels Systematischen Literaturanalysen (SLRs) abgesichert und ausgewählt. Aufbauend auf den gewonnenen Erkenntnissen wurde die Methodik zur Definition von Smart-circular PSS-Systemarchitekturen (MESSIAH) entwickelt, die Entwicklungsteams bei der Konzeptionierung von Smart-circular PSS unterstützt. Die Methode beinhaltet eine Modellierungsgenerik, eine gerichtete Methode sowie einen Baukasten zum schnellen Prototypisieren von Services. MESSIAH wurde mithilfe einer Comprehensive Descrip-tive Study anhand von fünf Studien evaluiert. Die Forschungshypothese konnte im Rahmen der Evaluierung verifiziert werden. Somit zeigt diese Arbeit erstmals Wege auf, wie Strategien der CE mithilfe des MBSE bei der Entwicklung von Smart-circular PSS Systemarchitekturen berücksichtigt werden können. MESSIAH ermöglicht die Modellierung einer interdisziplinären Systemarchitektur, die mechatronische Produkte, Software und Dienstleistungen integriert. Zur Modellierung von CE-relevanten Services wurden zwei neue prozessorientierte Modelltypen erfolgreich mit bestehenden Modellierungstechniken des MBSE kombiniert. Durch die Evaluierungsstudien konnte ein zufriedenstellender Stand der Akzeptanz und wahrgenommenen Nützlichkeit der Methodik nachgewiesen werden. Allerdings wurden Verbesserungspotentiale hinsichtlich ihrer Benutzbarkeit festgestellt. In weiterer For-schung wird es vonnöten sein, die Qualität und die Quantität der Anwendungsvalidierungen zu erhöhen. Zu diesem Zweck wird die Durchführung von Langzeitstudien sowie Anwendungen an industriellen Systemen in einem weiteren Einsatzspektrum und in weiteren Branchen empfohlen. In response to calls for digitization and servitization, businesses increasingly offer complex systems consisting of connected mechatronic products, software elements and services: so-called Smart Product-Service-Systems (Smart PSS). In order to meet the United Nations Sustainability Development Goals and in particular Goal 9 "Sustainable Consumption and Production", these systems must be compatible with the tenets of a Circular Economy (CE). The development of these systems presents businesses with major challenges. It remains unclear how engineering teams can be supported methodologically in developing Smart-circular PSS. This dissertation meets these challenges with the research hypothesis that suitable methods of Model-based Systems Engineering (MBSE) can aid in the development of Smart-circular PSS architectures, which effectively and efficiently contribute to a CE. The investigation applies Design Research Methodology (DRM) as an overarching research approach for hypothesis verification. Initially, expert workshops and an MBSE maturity analysis in an industrial enterprise served to clarify the research objective. Systematic Literature Reviews (SLRs) validated and detailed the fields of action identified. Based on the findings, the Methodology for Smart-circular PSS Architecture Definition (MESSIAH) was developed, which supports development teams in the design of Smart-circular PSS. The method includes a modeling framework, a method and a construction kit for prototyping services. MESSIAH was evaluated by means of a Comprehensive Descriptive Study based on five evaluation studies. The evaluation verified the research hypothesis. Consequently, this research explores how the development of Smart PSS with the help of MBSE can be useful to CE-strategies. MESSIAH enabled the management of system complexity by using an interdisciplinary system architecture that integrates the development of mechatronic products, software and services. In order to de-velop CE-relevant services, two new types of models were successfully integrated into existing modelling techniques of MBSE. User studies indicated a satisfactory level of user acceptance and perceived usefulness of the methodology, but also served to identify potential for improve-ment with regard to its ease of use. In further research it will be necessary to increase the quality and quantity of application validations in further application scenarios and other industry branches. For this purpose, the dissertation recommends long-term studies and applications on further industrial systems.

    Authors: Rieckmann, Marco;

    With the programme “Subject-related Partnerships with Universities in Developing Countries” the German Academic Exchange Service (DAAD) supports German universities in structure-building cooperation projects with partners in countries of the South. The German-foreign cooperation aims at giving both sides new impulses in teaching and the formation of new structures at the foreign university. Since 2009 the Institute for Environmental and Sustainability Communication at the Leuphana University of Lüneburg has implemented partnership projects with universities in Ecuador and Peru sponsored by the DAAD. The scientific evaluation of the project “Teaching and Learning Sustainability” with the Universidad Técnica del Norte (UTN), Ecuador, shows that the project contributes to the integration of the concept of sustainable development in teaching, research and administration at the UTN and that it opens opportunities for global learning for all participants. However, also challenges of North-South cooperation in higher education become apparent. (DIPF/Orig.)

    Authors: Zhang, Yajin;

    Seit dem Beginn des 20. Jahrhunderts ist die Entwicklung Neuer Städte ein sehr wichtiges Element der modernen Städtebautheorie und Städtebaupraxis. Auf der materiellen „Ebene“ haben die Neuen Städte mit der Unterstützung der Öffentlichen Hand eine hohe „Quantität“ der Massenbebauung ermöglicht, sie dient unterschiedlichen Entwicklungszielen auf der Ebene der Kommune, der Region und des Landes, ebenso wie der Behebung der Wohnungsnot, der Entlastung der Metropolen oder der Förderung von Wirtschaftszentren. Die Neue Stadt hat eine besondere natürliche „Qualität“, die regionale, gut eingebundene Lage der Neuen Städte, ihre Einbindung in die natürliche Umwelt und das hohe Niveau ihrer Infrastruktur und ihrer öffentlichen Einrichtungen. Der Bau Neuer Städte erweist sich geschichtlich immer als eines der wichtigsten Mittel zur Stärkung der kommunalen und regionalen Kompetenzkraft; deshalb wurden auch immer dann noch Neue Stadt-Quartiere gebaut, wenn die Wohnungsnot nicht mehr vorhanden war. Die Entwicklung der Neuen Städte ist auch ein ständiger Zeuge der Entwicklung der Städtebautheorien und von diesen im Positiven wie im Negativen ständig beeinflusst. Die Planung ganzer Neuer Städte ist eine der kompliziertesten Aufgaben des Städtebaus - die Realisierung ungeprüfter Innovationen, das schnelle Planungs- und Entwicklungstempo, die aus finanziellen Gründen oft schwach ausgeprägten öffentlichen Einrichtungen oder die Folgen einseitiger Sozialpolitik verstärken die Schwierigkeiten bei der Entwicklung einer Neuen Stadt. Das einseitige Übergewicht quantitativer Maßstäbe erzeugt eine Diskrepanz zwischen Qualität und Quantität. Die Neuen Städte als Aufgabe Das Thema der - so definierten - „Neuen Städte“ ist heute sowohl wegen der Erneuerungsbedürfnisse der „alten“ Neuen Städte, der Entwicklungsbedürfnisse der Neuen Stadt-Quartiere, sowohl in Europa, wie auch in der globalen Neue Stadt-Entwicklung von höchster Aktualität. Als ein Spiegel der modernen Städtebau-Entwicklung ist die Neue Stadt sowohl auf der Ebene der Forschung als auch der Praxis von sehr hoher Bedeutung, jedoch gibt es seit den 1970er Jahren zu dem Thema „Neue Stadt“ kaum noch Forschungsaktivitäten. In China ist die „Neue Stadt“, bereits in der Historie, immer ein wichtiges Element des Stadtentwicklungsmodells gewesen. Die Stadt ist der klar definierte Träger der speziellen Bedeutung: von der Gesellschaftsordnung über die Philosophie bis insbesondere zu der Politik. Die einschneidende Veränderung der chinesischen Kultur am Ende des Kaiserreiches - zu Beginn des 20. Jahrhunderts - führte zu einer Philosophie, welche die „westliche Kultur“ in Bezug auf Funktion und Form aufnimmt, jedoch die chinesische lokale Kultur als Seele - der Stadt - begreift. Diese Art der Trennung - der Stadtauffassung - beeinflusst die Philosophie der chinesischen Stadtentwicklung noch heute. Die 80er Jahre des 20. Jahrhunderts waren der Anfang der Ausbreitung der chinesischen Verstädterung. In diesem rasanten Verstädterungsprozess haben nicht nur die Metropolen, sondern auch die chinesischen Mittel- und Kleinstädte, die Neue Stadt als das wichtigste Instrument der Stadtentwicklung gewählt. Jedoch ist aufgrund des begrenzten Überblickes und des mangelhaften Wissensstandes, insbesondere für eine chinesische Neue Stadt heute, deren Grundlage in materieller sowie immaterieller Hinsicht schwach. Leitgedanken der Planung Neuer Städte Aus der hier dargestellten Forschungsarbeit lassen sich, als erster Teil der Arbeitsergebnisse, folgende Erfahrungen zusammenfassen: - Soziale Stadtgesellschaft: In der Planung einer Neuen Stadt ist nicht die Stadt selbst das wichtigste Entwicklungsziel, sondern vielmehr die Gesellschaft der Neuen Stadt. - Harmonische Humanität: Der eigentliche Zweck einer Neuen Stadt ist die harmonische Humanität, - d.h. die Schaffung eines Gleichgewichts der oft polaren Bedürfnisse der Menschen. - Global-historisches Stadtbild: Das Stadtbild, der Spiegel der immateriellen Qualität einer „Neuen Stadt“, ist deshalb ebenso wichtig wie die materielle Stadt und ihre funktionale Effektivität. Die Identität des Stadtbildes beruht auf einer Synthese von moderner, globaler Weltkultur und historischer, regionaler Kultur. Modell einer nachhaltigen Neue Stadt-Planung Aus diesem ergeben sich die Anforderungen an den Sinn, Inhalt und Ablauf der Planung einer Neuen Stadt sowie an den Hintergrund der Gründungsinitiative, die Gruppe der Initiatoren, den Planungsinhalt, den Arbeitsprozess, allgemeine Grundsätze des Städtebaus und der Planung Neuer Städte. Als Beispiele werden europäische und chinesische Neue Städte vor dem Hintergrund der Ansprüche der Menschen an ihre physische und psychische Umwelt analysiert. Since the beginning of the 20th Century, the development of new towns is a very important element of the modern urban planning theory and the practice of urban development. On a physical level, the new towns have a special “quantity” of large buildings and rich developed areas with support from the public sector. They serve different development objectives at local, regional and national levels, such as solving the housing shortage, the discharge of the metropolis, or the promotion of economic centers. The new city also has special natural born qualities, the location of the new towns, their integration into the natural environment, its high level of infrastructure and new public facilities. Historically, the establishment of new cities always proves to be one of the most important means to strengthen local and regional expertise; therefore nowadays more and more new city blocks are built, even when the housing shortage has no longer existed. The development of new towns is like witnessing the evolution of urban planning theories, from those in both the positive and negative influences. The planning of complete new towns is already one of the most complicated tasks of urban planning - it is believed that the problems are worsened by the realization of untested innovations, the rapid pace of development and planning, financial reasons, weak public facilities, or a one-sided social policy. The unilateral emphasis on the quantity causes discrepancies between quality and quantity. The new towns as a task The topic of the – so called – “new towns” requirements today both concern the renovation needs of the “old” new towns and the development needs of new communities in Europe and the global new urban development, from the most up-to-date. The new town as a mirror of modern urban development is highly meaningful from both a research and a practical level. However the research on the topic "New Town" has been almost complete since the 1970's. In China, the "new town" had historically been an important element of the urban development model. The town is a well-defined carrier having special importance to the social order and particularly in philosophy and politics too. The dramatic change in the Chinese culture at the end of the empire - at the beginning of the 20th Century - has led to a philosophy that accommodates the western culture in both form and functionalities, but the local Chinese culture as a soul – can be seen in the towns. This kind of separation - the town view - influenced the philosophy of the Chinese town development today. The 1980s was the beginning of the spread of Chinese urbanization. In this rapid urbanization process, it was not only the metropolises, but also the Chinese medium and small towns that chose the "new towns" as the most important characteristic of urban development. Nowadays, because of a limited overview and insufficient knowledge, the foundation of Chinese new towns seems to be weak materially and immaterially. Guide principle in planning new towns As the first part of the results of this paper, the following experience is summarized: - Social urban society: To plan a new town, the most important thing is not the town per se, but the society in a new town. - Harmonic Humanity: The real purpose of a New Town is a harmonious humanity – it means a human living environment - that is capable of all material and immaterial needs of all classes and all levels of generation to meet the prospective city inhabitant. - Global historical town: the town, a mirror of the immaterial qualities of a "New Town", is just as important as the physical town and its functional effectiveness. The identity of the cityscape is based on a synthesis of modern, global culture and historical, regional culture. Model of a sustainable new town planning Therefore the basis of a theoretical model for a new city can be determined. Things such as the background to the start-up initiative, the group of initiators, the content of planning, the work process and the general principles of urban design and planning of new towns. As an example, a new Chinese "New Towns" is analyzed with the context of requirements from a Chinese family on their physical and psychological environment.

    Authors: Bruchof, David;

    Vor dem Hintergrund allgemeiner energie- und klimapolitischer Ziele wie der Verringerung der Ölabhängigkeit oder der Reduktion der Treibhausgasemissionen werden hohe Erwartungen an den Einsatz alternativer Kraftstoffe und Antriebe im Verkehr geknüpft. Unsicherheiten bestehen jedoch in der Frage, welche Kraftstoff-Antriebskombinationen sowohl in ökonomischer als auch in ökologischer Hinsicht die besten Voraussetzungen mitbringen, um den gestellten Zielsetzungen gerecht zu werden. Die Beantwortung dieser Frage kann nicht durch eine isolierte Betrachtung des Verkehrssektors erfolgen, sondern erfordert zusätzlich die Berücksichtigung von Wechselbeziehungen zwischen dem Verkehrssektor und anderen Bereichen des Energiesystems. So müssen beispielsweise die während der Bereitstellung alternativer Kraftstoffe (Well-to-Tank) entstehenden Treibhausgasemissionen oder alternative Verwertungsmöglichkeiten für zur Kraftstoffbereitstellung eingesetzte Energieträger, wie z. B. Biomasse, in die Bewertung einfließen. Gerade im Hinblick auf ihren möglichen Beitrag zum Klimaschutz stehen verkehrspolitische Maßnahmen zur Senkung des Treibhausgasausstoßes zudem nicht nur untereinander sondern auch mit Vermeidungsoptionen in anderen Sektoren des Energiesystems im Wettbewerb. Das Ziel dieser Arbeit besteht daher darin, die mögliche Rolle alternativer Kraftstoffe und Antriebe als Teil einer energiewirtschaftlichen Verkehrsstrategie zu analysieren, welche darauf ausgerichtet ist, im Einklang mit allgemeinen energie- und klimapolitischen Zielen eine umweltverträgliche, bezahlbare und versorgungssichere Mobilitätsbereitstellung in Deutschland und der EU-27 zu gewährleisten. Dazu werden zunächst im Rahmen einer Technologiecharakterisierung unterschiedliche alternative Kraftstoffpfade und Antriebskonzepte bezüglich ihrer derzeitigen und zukünftigen technischen, ökonomischen und ökologischen Eigenschaften bis zum Jahr 2050 analysiert. Die Ergebnisse dieser Technologiecharakterisierung werden anschließend zusammengeführt, indem ausgewählte Kraftstoff-Antriebskombinationen in einem Well-to-Wheel Vergleich hinsichtlich ihrer Mobilitätskosten, Treibhausgasemissionen und Treibhausgasvermeidungskosten gegenüber konventionellen Antrieben auf Mineralölbasis bewertet werden. Aufbauend auf den Ergebnissen der Technikanalyse wird im Anschluss die mögliche Bedeutung alternativer Kraftstoffe und Antriebe in Deutschland und Europa bis zum Jahr 2050 unter Berücksichtigung der energie- und klimapolitischen Rahmenbedingungen sowie in Abhängigkeit von den technischen Entwicklungsfortschritten untersucht. Dazu wird eine modellgestützte Systemanalyse unter Anwendung des Energiesystemmodells TIMES PanEU durchgeführt, welche es ermöglicht, die genannten Wechselbeziehungen zwischen Verkehrssektor und restlichem Energiesystem zu erfassen und bei der quantitativen Bewertung der Potenziale alternativer Kraftstoffe und Antriebe einzubeziehen. Im Ergebnis zeigt sich, dass vor allem Biokraftstoffe und elektrische Antriebskonzepte, wie Batterie betriebene Elektrofahrzeuge und Plug-in-Hybridfahrzeuge, bei ambitionierten Klimaschutzvorgaben oder eingeschränkter Verfügbarkeit konventioneller Kraftstoffe langfristig (nach 2030) in zunehmendem Maße eine wichtige Rolle im Verkehrssektor spielen. Alternative fuels and power trains are often appreciated as possible options for the achievement of general targets from energy and climate policy like the decrease of oil dependency or the reduction of greenhouse gas emissions. However, uncertainties exist, which combinations of fuels and power trains are suited best from an economic and ecological point of view to cope with the existing requests. This question cannot be answered by an isolated analysis of the transport sector. Instead, an additional consideration of interdependencies among the transport sector and other sectors of the energy system is required. This comprises for example the inclusion of well-to-tank greenhouse gas emissions that occur during the preparation of alternative fuels or other possible options for the utilization of energy carriers that are needed as feedstock for alternative fuel production (e. g. biomass). Especially with regard to climate protection, measures for greenhouse gas mitigation in the transport sector are not only in competition among each other but also with measures in other sectors of the energy system. The intention of this study therefore is to analyze the potential role of alternative fuels and power trains as part of an energy economic transport strategy, which in the context of general targets from energy and climate policy aims at an environmentally friendly, affordable and secure mobility in Germany and the EU-27. The study starts with a characterization of the technical, economic and ecological properties of different pathways for alternative fuel production and alternative propulsion concepts, looking at the state of the art and the development until 2050. The results of this analysis are then used for a well-to-wheel assessment of selected combinations of alternative fuels and power trains regarding mobility costs, greenhouse gas emissions and greenhouse gas abatement costs related to conventional oil based vehicles. Based on the outcome of the previous investigation, the potential role of alternative fuels and power trains in Germany and the EU-27 as a whole until 2050 is evaluated, depending on the energy and climate policy framework and on the further technical development. For that purpose a model based analysis with the energy system model TIMES PanEU is applied, which allows to cover also the mentioned interconnections between the transport sector and the rest of the energy system. As a result of the analysis, especially biofuels and electric power trains like battery electric and plug-in hybrid electric vehicles prove to be important alternative technological options for the transport sector in the long run (after 2030), if ambitious climate targets are set or if the availability of conventional oil based fuels is limited.
