Um im Angesicht der Klimakrise eine lebenswerte Zukunft zu sichern, brauchen wir einen grundlegenden und raschen gesellschaftlichen Wandel. Wirksame Klimakommunikation kann eine wichtige Rolle spielen, um das für diesen Wandel erforderliche gesamtgesellschaftliche Engagement zu fördern. Im Forschungssemester wurden drei Ziele verfolgt: Erstens der Auf- und Ausbau des eigenen Kenntnisstands zur Klimakommunikation, zweitens das Kennenlernen der Arbeitsmethoden und -kultur des gastgebenden Think-Tanks Climate Outreach sowie drittens die Erstellung eines oder mehrerer für die Nachhaltigkeitstransformation nützlicher ‚Produkte‘ als Ergebnis des Forschungsaufenthalts. Alle drei Ziele konnten erreicht werden. Dabei bilden ein Working Paper, ein 4-Seiter für Praktiker sowie mehrere Artikel und ein Buchkapitel die Arbeitsergebnisse für andere nachvollziehbar und anwendbar ab (siehe Liste entstandener Veröffentlichungen in diesem Bericht). Inhaltlich war die Kernerkenntnis, dass Menschen sich ihre Meinung zum Klima und der eigenen Rolle in der Transformation nicht in erster Linie durch mehr und bessere Informationen bilden, sondern durch Geschichten, die ihre Werte ansprechen, die von Menschen erzählt werden, denen sie vertrauen, und die durch die Überzeugungen und das Verhalten der Menschen in ihrem Umfeld bestätigt werden. Klimakommunikation sollte also neben der rationalen Vermittlung von Fakten auch unsere emotionale Seite bedienen und beispielsweise zeigen, wie sich soziale Normen verändern und Klimaschutzhandeln zum neuen Normal wird.

Purpose In order to combat climate change and safeguard a liveable future we need fundamental and rapid social change. Climate communication can play an important role to nurture the public engagement needed for this change, and higher education for sustainability can learn from climate communication. Approach The scientific evidence base on climate communication for effective public engagement is summarised into ten key principles, including ‘basing communication on people’s values’, ‘conscious use of framing’, and ‘turning concern into action’. Based on the author’s perspective and experience in the university context, implications are explored for sustainability in higher education. Findings The article provides suggestions for teaching (e.g. complement information with consistent behaviour by the lecturer, integrate local stories, and provide students with basic skills to communicate climate effectively), for research (e.g. make teaching for effective engagement the subject of applied research), for universities’ third mission to contribute to sustainable development in the society (e.g. provide climate communication trainings to empower local stakeholders), andgreening the campus (develop a proper engagement infrastructure, e.g. by a university storytelling exchange on climate action). Originality The article provides an up-to-date overview of climate communication research, which is in itself original. This evidence base holds interesting learnings for institutions of higher education, and the link between climate communication and universities has so far not been explored comprehensively.

Our Earth is dangerously heating up and its future lies in our hands - but how can we make sure we don't drop it? On which levels does change happen and how can we inspire and motivate others to follow our example? In her personal story on how she not only challenged herself but also others, Maike Sippel lies out key questions everyone has to consider when taking action. She reports how her research provides the equipment to becoming a powerful change-agent for a save and vital future. This talk was presented to a local audience at TEDxKonstanz, an independent event.

Urban areas cause over 70% of direct and indirect CO2-emissions worldwide. To achieve the internationally agreed goal of limiting the global temperature increase to 1.5 to 2 ° C, considerable efforts to reduce emissions in cities are required. Mobilizing significant greenhouse gas reductions in cities is, however, a major challenge due to their very heterogeneous structures and a large number of small and varied emission sources (e.g. traffic, buildings). In addition, the organisational structures of urban emission sources are much more diverse than those of e.g. major industrial point sources. A general challenge for responsible decision-makers and institutions is that they have limited access to investment capital to implement large-scale measures to reduce greenhouse gas emissions. Carbon market mechanisms under Article 6 of the Paris Agreement can offer new opportunities for the mobilisation of large-scale emission reduction measures and policies. This research project first examined the prevalence and experience of urban reduction projects within the framework of the Clean Development Mechanism (CDM), Nationally Appropriate Mitigation Actions (NAMAs) and Transformative Actions Programs (TAP). Building on this, various conceptual approaches to the implementation of Art. 6 in cities were developed. In order to take appropriate account of the different national structures and framework conditions, a “menu approach” with uniform principles and standards is proposed. In addition, the study examines approaches to determine the additionality of urban mitigation activities and discusses various financing options.
