Limiting global warming to 1.5 degrees requires consistent action by people to change their lifestyles in order to limit annual household-related carbon emissions to 2.5 tonnes per person by 2030. As the required mobility reduction measures have already been identified, the challenge remains in scaling up the changes into a mainstream practice. Our study explored whether the involvement of close social communities, especially households, in the change process could be effective in achieving the required measures. Through a Climate Puzzle game intervention and a six-month follow-up study with 12 households in Espoo, Finland, we investigated the role of close social communities in implementing the planned sustainable mobility behaviour change. The findings are presented through 12 household narratives. These narratives show that the adoption of new sustainable mobility behaviours is influenced by both (infra)structural and social relationship factors and that close social communities can hinder or facilitate the shift of everyday mobility behaviours towards being more sustainable in diverse ways. The findings suggest that design interventions should target larger social communities rather than just individuals in order to achieve the 2.5 tonne target. The study also indicates that socially tailored interventions and low-carbon solutions should be developed and targeted at city districts to help households create and maintain lifestyle changes.
Das Wuppertal Institut wurde vom Rat für Nachhaltige Entwicklung beauftragt, Beispiele erfolgreicher Transformationen hinsichtlich ihrer Gelingensfaktoren zu analysieren, um daraus bundespolitische Maßnahmen zur Förderung und Skalierung kommunaler Nachhaltigkeitsaktivitäten ableiten zu können. Dafür wurden 14 Beispiele aus sechs Transformationsbereichen mit einem eigens konzipierten Analyseraster untersucht und in Factsheets kompakt aufbereitet.
Als kleiner Ausschnitt eines vielfältigen Engagements im Nachhaltigkeitsbereich zeigen die ausgewählten Beispiele, wie günstige Rahmenbedingungen eine Ermöglichungskultur schaffen, die die Diffusion erfolgreicher Praktiken erleichtert. Auf Bundesebene bedeutet dies einen Wandel vom steuernden zum ermöglichenden Staat, der lokale Spielräume erweitert und gleichzeitig die Koordination und Richtungssicherheit sowie die horizontale und vertikale Kohärenz der Instrumente sicherstellt. Trotz projektspezifischer und teils hoher Hürden lassen sich zentrale Gelingensfaktoren identifizieren: Anschlussfähigkeit an bewährte Maßnahmen, Sicherstellung der langfristigen Finanzierbarkeit, aktive Beteiligung lokaler Akteur*innen und eine geringe Konfliktwahrscheinlichkeit in der Umsetzung. Besonders hohe Akzeptanz genießen zudem Maßnahmen, die unter Einbindung und Vernetzung verschiedener gesellschaftlicher Akteur*innen umgesetzt worden sind.
Angesichts der immensen finanziellen Herausforderungen zur Schaffung und Wahrung nachhaltiger Lebenswelten stehen viele Kommunen vor einer fast unlösbaren Aufgabe, zumal tiefgreifende Veränderungen bis in die Lebensgewohnheiten der Menschen hinein nötig sind. Ein konsistenter und richtungssicherer Mix aus verschiedenen Lenkungsinstrumenten und von hoher Akzeptanz ist daher essentiell. Die untersuchten Transformationsbeispiele sind ein erster Einstieg in erforderliche Vertiefungsanalysen zur Wirkmächtigkeit potenzieller und konsistenter Politikpakete und deren Wechselwirkungen mit anderen Instrumenten im Mehrebenensystem.
Project-based learning, with its emphasis on "learning by doing", is the dominant teaching method in industrial design. Learners are supposed to be motivated to tackle complex problems such as those in the dynamic field of sustainability. However, it is still unclear how the process of increasing motivation within projects can be systematically targeted for specific sustainability challenges and directed towards potential later pro-environmental behavior.
The project-based learning method presented in this paper, framed by a normative decision-making model, aims to intrinsically motivate industrial design students to engage in the exemplary circular economy field of metal recycling and at the same time promote necessary professional competencies on the metal, alloy, product and system level. It is demonstrated which specific intervention measures can be suitable to achieve this goal and how they can be methodically employed. Preliminary quantitative evaluation results indicate that the project-based learning method can indeed strongly motivate the target group.
Given the urgent need to promote climate-friendly behaviours, the implementation of carbon footprint calculators with actionable recommendations is increasing. This study analysed data from >7000 users of a Japanese carbon footprint calculator to investigate the characteristics and factors affecting voluntary commitment to decarbonisation actions and the gaps in achieving the 1.5-degree mitigation target. The results showed voluntarily committed actions were insufficient to meet the 2030 personal carbon footprint target, with only 31 %, 18 %, and 7.3 % of users potentially achieving targets in the domains of housing, mobility, and goods/services, respectively. The seven user segments that were identified exhibited very different levels of engagement. For example, "lifestyle change enthusiasts" committed to as many as 25 actions, corresponding to an equivalent of 2.8 tCO2e of footprint reduction, while "curious bystanders" rarely committed to any actions. Demographically, younger and male users tended to prioritise high-impact actions, whereas female users and users aged 50–60 years old were more likely to commit to a range of actions. Notably, actions requiring substantial financial investment had an 8 % lower commitment probability, and "shift" actions were 6 % less preferred than "avoid" actions". These findings contribute to a deeper understanding of the considerable gap between self-committed actions and mitigation targets, and suggest that more effective use of footprint information could facilitate greater engagement. Tailored strategies could better motivate the "curious bystanders" segment and encourage female and older users to focus on high-impact actions.
Ways of evaluating the societal impact of real-world labs as a transdisciplinary and transformative research format are under discussion. We present an evaluation approach rooted in structuration theory, with a focus on structure-agency dynamics at the science-society interface. We applied the theory with its four modalities (interpretation schemes, norms, allocative and authoritative resources) to the case of the Mirke neighbourhood in Wuppertal, Germany. Six projects promoted the capacity for co-productive city-making. The effects of the projects were jointly analysed in a co-evaluation process. Previously proposed subcategories of the modalities as an empirical operationalisation were tested and confirmed as being applicable. Five new subcategories were generated. The use of the modalities seems appropriate for co-evaluation processes. The tool is practical, focused on real-world effects, and suitable for transdisciplinary interpretation processes. We encourage further empirical testing of the tool, as well as development of the subcategories.
Gaining deep leverage? : Reflecting and shaping real-world lab impacts through leverage points
(2024)
Real-world laboratories (RwLs) are gaining further traction as a means to achieve systemic impacts towards sustainability transformation. To guide the analysis of intended impacts, we introduce the concept of leverage points, discerning where, how, and to what end RwLs intervene in systems. Building on conceptual reasoning, we further develop our argument by exploring two RwL cases. Examining RwLs through the lens of the leverage points opens the way for a balanced and comprehensive approach to systemic experimentation. We invite RwL researchers and practitioners to further advance RwLs' transformative capacity by targeting the design and emerging direction of a system, contributing to a culture of sustainability.
Grüner Wasserstoff (H2) ist gemäß Transformationsszenarien für das deutsche Energiesystem eine Säule der Treibhausgasneutralität. Dabei ermöglicht der Import von grünem Wasserstoff oder anderen regenerativen Energierohstoffen vorteilhafte Bedingungen für erneuerbare Energien in anderen Ländern (bspw. bessere Wetterbedingungen und eine höhere Landverfügbarkeit) für uns nutzbar zu machen. Wie dies erfolgen könnte und was es dabei zu beachten gilt, wird in diesem Beitrag anhand von Forschungsergebnissen aus verschiedenen Projekten umrissen.
In light of Egypt's transition to a green economy, this report focuses on reducing greenhouse gas (GHG) emissions and increasing resource efficiency along three different value chains in which small and medium-sized enterprises (SMEs) play a crucial role. In order to support SMEs in Egypt to take advantage of implementing greening options along value chains, more detailed analyses are needed. Therefore, the aim of this study is to analyse three selected supply chains to identify greening opportunities for SMEs. Against this background, the project report is structured as follows: Chapter 2 introduces the background with an overview over the concept of green economy followed by Egypt's economy and its green economy. This is followed by a presentation of the value chains and an overview of the respective sectors. Chapter 3 describes the research approach, methods and data collection. The following chapters examine the three selected value chains cotton, sugar beet and refrigerators, including environmental hot spots, greening options as well as the experts' evaluation of those greening options. The report concludes with key recommendations in Chapter 7.
Die Auswirkungen der Erderwärmung - wie Dürren, Ernteausfälle und Waldbrände, aber auch Starkregen und Überschwemmungen - treten immer häufiger und heftiger auf. Im vorliegenden Zukunftsimpuls zeigen Forschende des Wuppertal Instituts, mit welchen Herausforderungen wir uns auseinandersetzen müssen und wie eine effektive und nachhaltige Anpassung an die Folgen des Klimawandels gelingen kann.
Das Impulspapier deckt eine große thematische Bandbreite ab: Neben Empfehlungen für den Umbau der Städte oder Anpassungen in Landwirtschaft und Gesundheitswesen, enthält es auch Ansätze zu naturbasierten Lösungen, zu wirtschaftlichen Chancen und Risiken sowie zu integrierten Strategien, die Klimaschutz und Klimafolgenanpassung intelligent miteinander verknüpfen.
Welche Alternativen gibt es zur rein bilanziellen Klimaneutralität? Beim Contribution-Claim-Modell unterstützen Unternehmen Klimaschutzprojekte, ohne die Emissionsreduktionen auf ihre eigene Bilanz anzurechnen. Ein Living-Lab-Projekt fördert die Verbreitung dieses Modells und trägt zu dessen Weiterentwicklung bei.
