80 % weniger Treibhausgasemissionen pro Person bis 2050 im Vergleich zum Basisjahr 1990 - mindestens - aber besser noch: 95 % weniger! So lautet die Herausforderung, die der Klimaschutz an ein zukunftsfähiges Deutschland und an einen zukunftsfähigen Stadtverkehr stellt. Das ist keine Kleinigkeit, die sich mit Verbesserungen im Detail erreichen ließe. Mit welchen Strategien kann also das angesagte Leitbild einer (fast) CO2-emissionsfreien Stadt im städtischen Personenverkehr verfolgt werden? Und in welchen Größenordnungen muss dabei eigentlich gedacht und gehandelt werden? Diesen Fragen nach den erforderlichen CO2-Minderungen wird mit einem Backcasting-Szenario, einem "Szenario des Erforderlichen" am Beispiel der Großstadt Wuppertal nachgegangen.
Können städtische und stadtregionale Verkehrskonzepte ausdrücklich am Klimaschutzziel orientiert werden, um das politisch formulierte Zwei-Grad-Ziel mit einer massiven Minderung der CO2-Emissionen von -80 bis -95 % bis 2050 gegenüber dem Basisjahr 1990 zu erreichen? Für München, Köln, Wuppertal, Tübingen, das östliche Ruhrgebiet und die Region Hannover liegen klimaschutzorientierten Szenarien zur künftigen Verkehrsentwicklung vor. Sie zeigen, wie es gehen kann.
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?
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 future belongs to the youth, but do they really have a say in it? Learning processes with regard to a successful socio-ecological change must start in childhood and adolescence in order to succeed in social transformation. The youth cannot be a passive part in a changing society - they have to be actively included in its design. When allowed to participate, young people can make important and effective contributions - which should not be reduced to sub-projects and opportunity structures. In a socio-political context, participation means involvement, collaboration, and commitment. In the context of intra- and inter-generational equity, as the core part of sustainable development, participation strategies should be developed that allow for a permanent and purposeful involvement of children and adolescents. Participation of young people is an important and appropriate step in strengthening those who are so strongly affected by the planning processes but are otherwise powerless. A successful involvement and participation of non-professional actors requires a target group-oriented method, a supportive culture of participation, as well as clarity and decision latitude. Abiding by these rules leads to central results.
Vision development towards a sustainable North Rhine-Westphalia 2030 in a science-practice-dialogue
(2017)
The paper presents the results of a participatory vision development process in the Federal State of North Rhine-Westphalia (NRW) in Germany. The vision development was part of a scientific research project that accompanied the development of a sustainability strategy for NRW at state level. The Sustainability Strategy NRW was adopted in July 2016 and contains parts of the vision developed in the research project: Sentences from the narrative text vision and proposed targets and indicators that back-up the vision for a sustainable NRW in 2030 were used by the state of NRW. The vision was developed in iterative steps in three consecutive dialogue rounds with different stakeholders from science and practice. The paper presents the methodological approach and the results of the vision formulation process. The paper discusses the lessons learned from the vision development - from both practical and theoretical perspectives of transition management. The paper explores the relevance of setting ambitious targets for sustainable development as part of a state strategy by taking the proposed target of a "4 × 25% modal split" by 2030 as an example. The project demonstrated that a participatory approach for vision development is time and resource consuming, but worth the effort as it improves the quality and acceptance of a vision. Furthermore, the project demonstrated that transformative science contributes valuable inputs for sustainability transitions and for facilitating participatory vision development.
