Welche Perspektiven haben zukunftsfähige und krisenfeste Städte nach der Corona-Pandemie? Antworten darauf skizzieren die Autorinnen und Autoren in dem vorliegenden Diskussionspapier. Ihre zentrale These: Städte der Zukunft müssen und werden "näher", "öffentlicher" und "agiler" sein. Dies erläutern sie anhand dieser drei Dimensionen und konkretisieren es anhand zahlreicher Beispiele.
The 2014 United Nations Climate Change Conference had been scheduled from 1 to 12 December in Lima/Peru. While in the run-up to the conference, China and the US in a surprise bilateral move had announced plans to cut greenhouse gas emissions that exceeded expectations, the conference was characterised once again by a deep division between key players from the former so-called "developed" and "developing" world. The negotiations thus took 32 hours longer than planned and ended on Sunday morning at 1.22 am. More importantly, the conference failed almost completely to resolve the tasks it was supposed to do in order to prepare the last round of negotiations before next year's conference in Paris 2015, which is supposed to deliver a comprehensive future climate agreement. A team of researchers from the Wuppertal Institute attended the conference and have compiled a first assessment of the results.
The study "A Green New Deal for Europe" consists of two basic elements: Firstly it aims to cope with the economic crisis through intensive measures in order to systematically stimulate the eco-industries, to create jobs and to boost economic recovery. Secondly it aims at establishing the foundation for a green modernisation of the European economy. The study examines existing EU strategies policies and programs concerning their suitability to implement the Green New Deal. It proposes exemplary measures in the field of energy, mobility and resource use. The study has been compiled by the Wuppertal Institute on behalf of the Greens/European Free Alliance (EFA) Group in the European Parliament.
National welfare is no longer an effective frame of reference for enlightened foreign policy. Policy consideration must encompass the common welfare of a world society. Environmental and resource crises are inextricably tied to security and justice. Sixty years after the founding of the United Nations there should be a new effort to establish a genuinely sustainable global order - a "San Francisco 2.0".
Given large potentials of the MENA region for renewable energy production, transitions towards renewables-based energy systems seem a promising way for meeting growing energy demand while contributing to greenhouse gas emissions reductions according to the Paris Agreement at the same time. Supporting and steering transitions to a low-carbon energy system require a clear understanding of socio-technical interdependencies in the energy system as well as of the principle dynamics of system innovations. For facilitating such understanding, a phase model for renewables-based energy transitions in MENA countries, which structures the transition process over time through the differentiation of a set of sub-sequent distinct phases, is developed in this article. The phase model builds on a phase model depicting the German energy transition, which was complemented by insights about transition governance and adapted to reflect characteristics of the MENA region. The resulting model includes four phases ("Take-off renewables", "System integration", "Power to fuel/gases”, "Towards 100% renewables”), each of which is characterized by a different cluster of innovations. These innovations enter the system via three stages of development which describe different levels of maturity and market penetration, and which require appropriate governance. The phase model has the potential to support strategy development and governance of energy transitions in MENA countries in two complementary ways: it provides an overview of techno-economic developments as orienting guidelines for decision-makers, and it adds some guidance as to which governance approaches are suitable for supporting those developments.
"Sufficiency" is beginning to emerge as a new value throughout Western societies and the question asked in this article is: Can we observe cases with actual opportunities to link successful business strategies of incumbents to principles of sufficiency? Thus, how feasible is sustainable entrepreneurship for incumbents? As an innovative conceptual approach, it will be analyzed how brand claims function as narrative translation mechanisms in situations where tensions emerge between corporate narratives and unexpected societal trends, e.g. the emergence of sufficient lifestyles. It will be shown that even though these are still a niche phenomenon, a focus on powerful brands and the narratives connected to them are an important element in understanding the role of incumbents in transitions to sustainability.

The European Union (EU) has established that the goal of achieving climate neutrality by 2050 as a key driver of innovation and growth for industry and the economy in the EU. In addition to offering great opportunities, this also poses considerable challenges for the European economy and, for the most part, for basic industries, which are particularly emission-intensive and face strong international competition.
An integrated climate and industry strategy is of central importance to protecting the climate, since the production of steel, cement, basic chemicals, glass, paper, and other materials in the EU and worldwide accounts for roughly one fifth of total greenhouse gas emissions. Even in a greenhouse gas-neutral future, we will not be able to fully eliminate our need for these materials. At the same time, it is particularly challenging to produce these materials without creating emissions given the state of technology and the necessary infrastructures. This applies above all to the question of how large amounts of green energy, including electricity and hydrogen, can be produced at competitive prices. Analyses show that despite the considerable costs involved in process changeover, the costs of transforming the raw materials industry are acceptable to society as a whole, given that the additional costs usually only increase the price of the end products by a few percentage points. However, in the case of crude steel or cement, the price would increase by between one third and 100 per cent. Since almost all raw materials manufacturers face strong global market competition, in most cases they are not able to bankroll the investments in climate-neutral production and the required energy infrastructure without outside support.
This paper outlines an integrated climate industrial policy package that allows the EU to utilise its existing technological leadership in many of these industries to build a greenhouse gas-neutral raw materials industry.
In der Analyse wurden die wesentlichen, in Thüringen vorhandenen nachhaltigkeitsrelevanten Strukturen und Akteure analysiert. Ziel war es, Handlungsempfehlungen zu entwickeln, wie die zukünftige Arbeit der nicht-staatlichen Nachhaltigkeits-Partnerinnen und -Partner und der Landesregierung Thüringen weiterentwickelt und verbessert werden kann. Für die Analyse wurden leitfadengestützte Experteninterviews und ein Akteurs-Workshop durchgeführt.
The current momentum in the electrification of the car fuels hope for a transition in mobility. However, electric vehicles have failed before and it is thus asked: What is the potential of e-mobility developing as a sustainable system innovation? In order to deal with this challenge analytically, a theoretical framework is developed: the concepts of transformative capacity of a new technology (do electric vehicles trigger "social" innovations, e.g. new business models or use patterns?) and system adaptability (how stable is the mobility regime?) are introduced and the issue of sustainability is discussed. This framework will be explored for the German innovation system for e-mobility. It can be shown that electric cars will only be successful when part of a system innovation and that the German innovation system is dominated by regime actors and thus potentially used as a way to fend off more substantial change.
The multi-level perspective has successfully been applied to the analysis of complex sector transitions in the energy, the health or the food production sector. Is this framework also helpful to understand and give prescriptive advice for sustainability transformations within a national science system? Based on a comprehensive study of the diffusion of transdisciplinary sustainability research in Germany, this article analyzes the institutional dimension of a changing science-society relation in the German science system. It uses the multi-level perspective as a fruitful heuristic in order to identify potential pathways for a broader diffusion of transdisciplinary sustainability science. The importance of niche coalitions of frontrunner universities and research institutes are highlighted.
Wie viel ist genug? - Diese Frage stellt sich unausweichlich angesichts der offensichtlichen sozialen und ökologischen Probleme in der Welt. Gefragt ist nicht nur ein ressourcenleichtes Wirtschaftssystem, sondern eine leistungsbefriedete Gesellschaft, die den geordneten Rückzug aus der Wachstumslogik schafft, weil das Wohlergehen aller ihr Ziel ist.
Dieses Wuppertal Paper richtet sich an die interessierte Öffentlichkeit sowie an Produzenten und Dienstleister, die zur Anpassung an den Klimawandel beitragen können. Es gibt zunächst einen Überblick zur Problematik des Klimawandels und über die voraussichtlichen Schäden bzw. die Kosten der Anpassung. Die Autoren beschreiben sodann die Auswirkungen auf klimasensible Wirtschaftsbereiche und skizzieren schließlich die Chancen, die sich für die Unternehmen aus der zukünftig notwendigen Anpassung in vielen vom Klimawandel betroffenen Bereichen bieten. Fazit: Der Erfolg bei der Anpassung der bestehenden Produkte sowie bei der Gestaltung neuer Produkte an den Klimawandel wird auch maßgeblich über die künftigen Marktchancen von vielen Unternehmen in Deutschland und darüber hinaus entscheiden.

Aus für Benzin- und Dieselfahrzeuge ab 2030 : der richtige Innovationsimpuls für die Verkehrswende?
(2016)
Seit der Bundesrat gefordert hat, dass ab 2030 nur noch emissionsfreie Fahrzeuge zugelassen werden sollen, hat die Debatte um den richtigen Weg in die Zukunft der Mobilität an Fahrt aufgenommen. Prof. Dr. Uwe Schneidewind und Prof. Dr. Manfred Fischedick begründen, warum die Bundesrats-Initiative, die de facto einem Zulassungsverbot für neue Benzin- und Dieselfahrzeuge gleichkommt, genau den richtigen Innovationsimpuls setzt - und es falsch wäre, ihn mit einseitigen Festlegungen zu verbinden.
Die Innenstadt von Wuppertal Elberfeld wird im kommenden Jahrzehnt konsequent und Schritt für Schritt zu einem autoverkehrsfreien Stadtteil entwickelt. Wuppertal Elberfeld wird damit der erste bestehende Stadtteil in Deutschland, der systematisch von einem Autostadtteil heute zu einem zukünftig autoverkehrsfreien Stadtquartier entwickelt wird.
Von einer autofreien Innenstadt profitieren die Menschen, die Umwelt und die Stadt Wuppertal. Hier kann man die Verkehrswende Wuppertal konkret erleben und Urbanität genießen.
Welche Gewinne dadurch entstehen können und wie der Weg dorthin aussehen könnte, skizzieren die Autoren in diesem Impulspapier, um die Diskussion über das Ziel und den Weg dahin zu eröffnen.
Ben A. Minteer: The landscape of reform - civic pragmatism and environment thought in America
(2007)
Stockholm, Hamburg, Vitoria-Gasteiz, Nantes, Kopenhagen, Bristol, Ljubljana, Essen - das sind die Europäischen Umwelthauptstädte der Jahre 2010 bis 2017. Sie wurden in einem jährlichen europaweiten Wettbewerb von der Europäischen Kommission als Vorbildstädte ausgewählt. Sie zeigen aus Sicht der Europäischen Kommission, wie eine zukunftsfähige, umweltorientierte Stadtentwicklung im 21. Jahrhundert aussehen kann. Welchen EU-Benchmark markieren diese acht Städte für die Gestaltung eines klimaschonenden Personenverkehrs in der Stadt?
Seit der im Jahr 1972 erschienenen Studie "Grenzen des Wachstums" hat sich die ökologische Debatte stark auf die Gefahr der Verknappung von Rohstoffen konzentriert. Die neuere Umweltforschung zeigt, dass noch weit vor dem Ende der fossilen Rohstoffe andere Umweltgrenzen überschritten werden. Der Beitrag widmet sich den sich daraus ergebenden Konsequenzen für Unternehmen.

Building a "theory of sustainable development" : two salient conceptions within the German discourse
(2008)
This paper identifies a lack in sustainability science, of a well-founded normative basis, for the justification of sustainable development. In order to fill this gap, we aim at calling attention to two of the salient conceptions in the German discourse, namely the "Theory of Strong Sustainability" developed at the University of Greifswald and the "Integrative Sustainability Concept" proposed by the Helmholtz Association of German Research Centres (HGF), the biggest research institution in Germany. Both conceptions highly value the justification of a strong theoretical and normative core of sustainable development. This paper suggests that a well-founded "theory of sustainable development" provides the distinctiveness that allows the assessment whether or not there is progress towards sustainability. A clear scientific comprehension of sustainability may inform politics in sustainability affairs and function as a rational corrective for the otherwise diffuse discussion in the general public.
Business model resilience : understanding the role of companies in societal transformation processes
(2017)
Business model resilience (BMR) is introduced as a conceptual framework to better understand the systemic dimension of companies affected by and shaping sustainability transformations. It offers an interdisciplinary approach for management studies and a framework for orientation in management practice.
Die große Resonanz auf die Idee der Bürgerwissenschaftist auch Ausdruck für den Bedeutungsverlust der Hochschule in der Gesellschaft. Hochschulen scheinen kaum präsent im Ringen um viele gesellschaftlich brennende Fragen: zum Beispiel bei der Suche nach neuen Modellen der Ökonomie oder bei der Entwicklung angepasster Technologien. Doch Hochschule und Bürgerwissenschaftmüssen kein Gegensatz sein - im Gegenteil: Als Bürgerhochschule kann die Hochschule zum wichtigen Katalysator einer starken Bürgerwissenschaft werden.
Cities as "real world laboratories" for system innovations : theories, models and empirical designs
(2012)
At the time of the Rio Conference, it had already become clear that climate change is far from being just an ecological issue; it is also an issue of equity. In particular, climate change was identified as an issue of intergenerational equity. It became ominously clear to observers that global warming, since it modifies important parameters of the ecology of the planet, such as sea levels or weather patterns, will affect the relations between present and future generations. Today's generation, by filling up the absorptive capacity of the atmosphere, lives at the expense of tomorrow's generation. At the same time, it came to the fore that the use of fossil fuels not only affects inter-generational equity, but also intra-generational equity, i.e., the relations between nations and social groups within a generation. Who will be allowed to reap the benefits from fossil fuel combustion? Who will have to carry the burden of emission abatement? Equity within a generation has at least two dimensions (Wuppertal Institute, 2005). First, it implies the fair distribution of burdens and benefits of fossil fuel use among nations. Secondly, however, it also implies the universal protection of human dignity by securing the fundamental rights of every human person to water, food, housing, and health. The article will focus on the latter dimension; it will explore the links between human rights and climate change, without, however, losing sight of the broader framework of equity in climate politics.
This paper analyses the results of the climate conference in Lima 2014 in the light of the coming climate summit in Paris by the end of this year (COP21). The authors from the Wuppertal Institute make recommendations for the improvement of the current cooperation in the context of the climate convention and they suggest to complement the existing UN regime with a club of forerunner countries in order to provide new breath for international climate policy.
In 2005 two very important milestones of international climate policy were reached: The entry into force of the Kyoto Protocol and the installation of a European wide emissions trading system. In Germany, the publication of the fifth report of the inter-ministerial working group on climate policy was published with an evaluation of climate protection policies. In 2004 the Japanese climate protection policy was fully revised so that Japan will also bring forth important developments in this area. The traditional close cooperation in this area between Japan and Germany, must now result in more concrete projects to keep this dynamic going well into the future. There is much potential to achieve a lot.
Within the unique framework of the Germany in Japan Year 2005-2006, the German Ministry for the Environment, the Ministry for Innovation of Northrhine-Westfalia, together with the Institute for Global Environmental Strategies (Japan) and the Wuppertal Institute (Germany) put together a two day event in Tokyo comprising an experts workshop and a one day conference.
At the conference, experts and practitioners of the German government, the states, the private sector and environmental organisations from Germany and Europe presented the decisive factors for success as well as the difficulties encountered namely in introducing an eco-tax and the Emissions Trading Scheme. Japanese experts and practitioners reported on Japanese approaches and reviewed the German/European experiences in light of the Japanese situation. At the expert workshop, researchers and decision makers discussed the experiences with policy dialogues and stakeholder involvement. They assessed the transferability of German/European experiences into the Japanese context and the broader inclusion of civil society into the governmental decision making process, that is so say, the opportunities in co-operating with politics, private sector and environmental organisations. This report documents the events and highlights the most outstanding conclusions and ideas for further cooperation in the future.
In less than ten years, emissions trading has forged ahead as a climate policy instrument - from the setting of the agenda through the formulation of policy to the stage of implementation. This has happened at several policy levels: on the one hand, as international emissions trading in the framework of the Kyoto Protocol, and on the other hand as emissions trading for energy-intensive companies within the European Union. Not only because of the speed of the process, but also because emissions trading is generally being perceived as an effective means to avoid greenhouse gas emissions, ist introduction is mostly regarded as a success story. This claim is here critically examined with the help of a number of theoretical hypotheses borrowed from the field of multilevel governance research. The theoretical discussion is woven into a detailed descriptive-analytic account of the introduction of emissions trading, bringing out the most important players, conflicts and milestones in the process. What were the consequences of this rapid introduction for the interdependence of players and institutions in the multi-level policy system? To what extent was it accompanied with a transfer of authority from national governments to supranational or international institutions? Can we speak here of a further loss of sovereignty by national states in the age of globalisation? And has the introduction of emissions trading, as a new generation of climate policy instruments, brought about institutional changes in negotiation patternsand decision-making processes? This set of questions is being derived from the concept of multi-level governance which serves as the framework of analysis of this paper and is then being used to analyse fifteen theses in order to explain the complexity of the introduction of emissions trading and highlight problems and deficits in the negotiating processes. The aim of the paper is to give a answer to the question of whether the meteoric rise of the policy instrument may be described as a "success story".
Six German scenario studies on urban passenger transport for Munich 2058, Wuppertal 2050, Eastern Ruhr Region 2030, Tuebingen 2030, Cologne 2020 and Hanover Region 2020 investigate the key question: With which strategies and on what kind of scale, is it possible to reduce the carbon dioxide emissions of urban passenger transport to accomplish the 2 °C climate protection goal with a consequently huge reduction of greenhouse gas emissions by 80% to 95% by 2050 in relation to the base year 1990? The scenarios show that the major challenge of a "climate-friendly city transport" can be achieved by appropriate measures (regarding direction and scale): in small and medium-sized cities, large cities, cities of over a million people, and metropolitan regions. The scenarios demonstrate the extent to which the considered measures contribute to the CO2 reduction, and which gap to the achievement of the goal remains if that which is currently regarded as realistic in practice is really implemented in future. Thus, they illustrate the conflict between that which is necessary for climate protection and that which is currently considered feasible in politics. The scenarios show that it is essential to act quickly and appropriately, and not hesitantly or without conviction.
The paper sketches out a theoretical framework for analysing the interplay between eco-efficiency, cognition and institutions. It derives from analytical shortfalls of the prevailing literature, which features strongly engineering and business economics, by using insights from New Institutional Economics, from Cognitive Science and, partly, from Evolutionary Economics. It emphasises the role cognition and institutions play in the adoption of "green" technologies by firms. A cognitive perspective derives from recent research on simple heuristics and context-based rationality; it is proposed that those findings can serve to analyse decision-making of individual actors respectively firms and, thus, should complement economic analysis. A second proposition is that eco-efficiency and normative rules such as a Factor Four strongly rely upon institutions, i.e. the ability of institutions to evolve over time and the development of those institutions that are most appropriate to enhance technological change. In this regard, business institutions and competition are crucial, but regulatory needs remain in order to safeguard continuity of knowledge creation. The framework allows for an analysis why overall adoption of eco-efficiency still can be considered relatively slow and why some markets and firms are far ahead. As a brief case study the article reflects upon German waste law's ability to enhance eco-efficiency.

In the face of persistent sustain ability problems challenging economic development, ecological integrity as well as social justice, transformational changes are crucial. Proposed changes shall include, for instance, large-scale transitions of practices, infrastructures as well as values and priorities. In Germany, real-world laboratories are proposed for research in and with society, aiming to understand and contribute to transformations.
Die Debatte um den Veggie-Day hat gezeigt: sehr schnell wird das alte Konfliktmuster "Freiheit vs. Staat" aktiviert. Selbst das eingestaubte Bild einer "Ökodiktatur" dient wieder als Schreckgespenst und Wahlkampfhilfe. Dabei lohnt es sich sehr wohl, über das Verhältnis von Staat und individueller Freiheit zu streiten. Uwe Schneidewind und Angelika Zahrnt zeigen in dem Buch, wie dieses Verhältnis im Zeitalter der Nachhaltigkeit neu auszutarieren ist und ein zeitgemäßer Liberalismus aussehen kann. Das Buch erweitert den Blick auf die Debatte über die Wohlstandspolitik und es provoziert. Es verbindet die individuelle Suche nach dem guten Leben mit der Aufforderung an die Politik, diese Suche zu erleichtern und zu unterstützen. Wo hat die individuelle Konsumfreiheit heute ihre Grenzen, wenn wir - wie z. B. beim Klimawandel - um ihre weltweiten Folgen wissen? Wer hat die Verantwortung dafür, dass ökologische Grenzen eingehalten werden? Welchen Handlungsspielraum hat das Individuum und wie kann Politik ihn erweitern? Eine gute Politik sorgt dafür, dass eine Vielfalt individueller Lebensstile möglich ist, ohne die Lebensentwürfe anderer einzuschränken. Sie schafft Möglichkeitsräume für gutes Leben, so die beiden Autoren. Von einer ökologisch orientierten Wirtschaftsordnung über die Gestaltung einer auf das richtige Maß setzenden Stadt- und Verkehrspolitik bis zu neuen Impulsen in der Verbraucher-, Arbeits- und Gesundheitspolitik reichen dabei die Ansatzpunkte einer Suffizienzpolitik. Das Buch zeigt die Ansätze auf und entwickelt daraus ein umfassendes politisches Programm.
Das beste Instrument : ökologische Steuerreform ; intelligente Steuerung des ökologischen Umbaus
(1995)
Ein undurchsichtiger Tarifdschungel, unzureichende Verbindungen und ungerechtfertigt hohe Preise - das schreckt viele Menschen davon ab, den Bus oder die Bahn zu nehmen. Wegen der anhaltenden Unterfinanzierung stehen bessere ÖPNV-Angebote nicht in Aussicht. Dabei ist es gerade aus Klimaschutzgründen erforderlich, den öffentlichen Personennahverkehr als Rückgrat einer klimaschonenden Mobilität auszubauen und seinen Anteil im Verkehr in Stadt und Region zu steigern.
Das neue Finanzierungsmodell "Bürgerticket" könnte dazu beitragen: Es könnte eine stabile Finanzierungsbasis schaffen und den Umstieg vom Auto auf den ÖPNV fördern. Für das Bürgerticket wird von allen ein zweckgebundener Solidarbeitrag zur Finanzierung der ÖPNV-Betriebskosten erhoben. Im Gegenzug haben dann alle Bürgerinnen und Bürger freie Fahrt in Bussen und Bahnen. Ein "Semesterticket für alle" - das ist die Idee.
Der Autor hat am Beispiel Wuppertals den möglichen Einfluss des Bürgertickets auf die Verkehrsmittelwahl untersucht und daraus Klimaschutzpotential sowie Kosten in Szenarien abgeschätzt. Abgerundet wird die Studie durch Vorschläge für Politik und Wirtschaft, wie dieses innovative Finanzierungsmodell in der Praxis umgesetzt werden kann.
Während der gesamten Dauer seines Lebens ist der Mensch beständig mit dem Phänomen "Knappheit" konfrontiert. Er muss essen, trinken, sich vor den Unbilden der Natur schützen - und das unter widrigen Bedingungen wie Kälte und Hitze oder beschränkter Nahrungsverfügbarkeit in vielen Regionen der Erde. Vor diesem Hintergrund der "Knappheit" hat die Menschheit jedoch beeindruckende Zivilisationsleistungen vollbracht: die Entwicklung der Landwirtschaft seit dem Neolithikum, die Gründung von Städten, den Aufbau industrieller Produktion ab dem späten 18. Jahrhundert. Mit jedem Schritt entstanden dabei neue Erfahrungen von Fülle, im Sinne von materiellem Reichtum, aber auch von wachsendem Bewusstsein für die nichtmateriellen Faktoren, die ein erstrebenswertes Leben auszeichnen, z. B. Bildung, Kultur und gesellschaftliche Teilnahme.
Uwe Schneidewind definiert Suffizienz und erläutert die Hintergründe.
Für Ernst Ulrich von Weizsäcker steht fest, daß das nächste Jahrhundert das Jahrhundert der Umwelt sein wird. Wenn die Menschheit überleben will, muß dem Schutz der Natur höchste Priorität eingeräumt werden. Von Weizsäcker entwirft ein neues Leitbild für zukunftsfähiges Wirtschaften und demonstriert anhand der weltweiten Projekte der EXPO 2000 - vom abwasserfreien Haus über die Solarsiedlung Freiburg bis zum Rottaler Modell für Strom aus der Biotonne -, daß Öko-Effizienz nicht mehr reine Theorie ist, sondern bereits umgesetzt wird: So könnte eine Zukunft aussehen, in der weniger Naturressourcen verbraucht werden, ohne daß der Lebenssstandard sinkt.
Namhafte Autoren aus führenden nicht-staatlichen Organisationen ergänzen den Band um faszinierende Visionen, wie eine zukunftsfähige Welt zu gestalten ist. Sie beschreiben u.a. Szenarien für Nachhaltigkeit in Europa und Lateinamerika, fordern einen globalen Technologiepakt und fragen nach der Rolle der Entwicklungsländer im Globalisierungsprozeß.
Ausgehend von internationalen Klimaschutzzielen wird der ÖPNV in Zukunft eine tragende Rolle zur Sicherstellung der Mobilität spielen müssen. Investitionen in ein besseres ÖPNV-Angebot sind auf Grund leerer öffentlicher Kassen allerdings kaum absehbar. Darum wird eine Solidarfinanzierung für den ÖPNV vorgeschlagen: das Bürgerticket. Damit soll eine solide Finanzierungsbasis geschaffen werden. Zugleich könnte die verpflichtende Zahlung bei den Bürgern als ein zusätzlicher Anreiz zur ÖPNV Nutzung wirken.
