Angesichts von Extremwetterereignissen, Klimaprognosen und Bewegungen wie Fridays for Future lässt sich schwer leugnen, dass ein Teil der Menschheit auf eine Weise lebt, die eine gut bewohnbare Welt höchst unwahrscheinlich macht. Städten wird in dieser Situation eine zentrale Rolle zugeschrieben. Sie können die Welt vor der Erderwärmung retten - oder sie sind die Ersten, die untergehen. Doch was genau wird getan, um Städte in Richtung Nachhaltigkeit zu transformieren? Britta Acksel nimmt Aktionspläne, Klimafestivals, Awards und weitere Transformationsinstrumente in den Blick. Ethnographisch fundiert zeigt sie auf, wie sich die Arbeit mit dieser speziellen Form von Policy-Werkzeugen gestaltet - und welche Bemühungen besonders aussichtsreich erscheinen.
This paper presents a novel governance concept for sustainable development, introducing the "Safe System Approach" as a transformative model that shifts focus from individual behavioural change to systemic transformation. This approach challenges traditional governance models that emphasize individual responsibility in achieving sustainable development and decarbonization. Instead, it advocates for creating an enabling environment that inherently guides individuals and communities towards sustainable actions. The Safe System Approach is centred on delivering low-carbon services across essential sectors, including electricity, mobility, industry, buildings, human settlements, and agriculture, thereby embedding sustainability as a default choice in societal systems. Drawing parallels with successful models in road safety, the paper explores the potential of this approach in urban development and climate action. It emphasizes the need for a broad coalition and integrated approaches in managing shared resources, highlighting the significance of systemic adjustments over individual behavioral change. By proposing a structure where sustainability is facilitated by the system's design, the paper builds on key concepts from seminal works by scholars like Garrett Hardin, Mancur Olson, Elinor Ostrom, and Ahrend Lijphart. It discusses the challenges and opportunities in creating safe operating spaces for sustainable development, emphasizing the need for multi-actor, multilevel governance systems that can manage shared resources sustainably and are resilient to political volatility. The paper aims to offer a robust, efficient, and inclusive pathway to sustainable development, contributing to the global discourse on environmental and social resilience.
Reaching net-zero in the chemical industry : a study of roadmaps for industrial decarbonisation
(2024)
Striving to mitigate climate change, the European Union has adopted net-zero greenhouse gas emissions as a target for 2050. In this paper, European chemical industry roadmaps from the past six years are assessed and compared to uncover how the industry envisions its role in the transition to net-zero emissions. The roadmaps are assessed in terms of ambition level, technology and feedstock strategies, investment needs and costs, agency and dependency on other actors, as well as timeline and concretion. Although net-zero pathways are often drawn out in the roadmaps, some also choose to emphasize and argue for less ambitious pathways with emission reductions of only 40-60 %. The roadmaps vary widely in terms of the importance they assign to mechanical and chemical recycling, switching to biogenic carbon and carbon dioxide as feedstock, electrification and hydrogen, and carbon capture and storage. A commonality though, is that low-tech or near-term mitigation pathways such as demand reduction, reuse or material efficiency are seldom included. High investment needs are generally highlighted, as well as the need for policy to create enabling conditions, whereas the agency and responsibility of the chemical industry itself is downplayed. Our analysis highlights that the chemical industry does not yet have a strong and shared vision for pathways to net-zero emissions. We conclude that such a future vision would benefit from taking a whole value chain approach including demand-side options and consideration of scope 3 emissions.
Für Deutschland und viele Industrieländer weltweit wird der Import von grünem Wasserstoff ein zentraler Baustein auf dem Weg zur Klimaneutralität sein. Dabei muss einerseits gewährleistet sein, dass grüner Wasserstoff auch wirklich "grün" im Sinne von klimaneutral ist. Zugleich gibt es immer mehr Forderungen, dass auch andere Nachhaltigkeitskriterien - soziale, ökonomische und ökologische - bei der Produktion und dem Transport von Wasserstoff eingehalten werden. Der politisch getriebene Aufbau einer globalen Wasserstoffwirtschaft bietet von Anfang an die Möglichkeit, diesen Sektor in Einklang mit den bestehenden politischen Zielen zu bringen. Dazu zählen beispielsweise die Pariser Klimaziele oder die Agenda 2030. Die Industrienation Deutschland, die auch in Zukunft auf Energieimporte angewiesen sein wird, kann hier als führende Industrienation als Vorreiter Einfluss nehmen. Damit kann nicht nur sichergestellt werden, dass der nach Deutschland importierte Wasserstoff "grün und nachhaltig" ist, sondern auch die Nachhaltigkeit des globalen Wasserstoffmarktes insgesamt beeinflusst werden.
Diese Kurzstudie untersucht, welche bereits existierenden Politikinstrumente geeignet sind, Nachhaltigkeitskriterien für Wasserstoffimporte zu verankern und im Zusammenspiel den Weg zu einem nachhaltigen globalen Wasserstoffmarkt zu unterstützen. Dabei werden ausschließlich Nachhaltigkeitsziele und -kriterien jenseits der Klimawirkung von Wasserstoff analysiert. Es ist unbestritten, dass das zentrale Ziel der Wasserstoffwirtschaft die Reduktion von Treibhausgasen bis hin zur Klimaneutralität ist, was bereits in einer Vielzahl von Studien und Stellungnahmen diskutiert wurde. Daher wird in dieser Studie von der Klimaneutralität des grünen Wasserstoffs ausgegangen, um den Fokus auf die anderen wesentlichen Nachhaltigkeitsaspekte zu lenken, die für den Import von grünem und nachhaltigen Wasserstoff aus dem Globalen Süden von entscheidender Bedeutung sind.
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.
Green hydrogen and synthetic fuels are increasingly recognized as a key strategic element for the progress of the global energy transition. The Middle East and North Africa (MENA) region, with its large wind and solar potential, is well positioned to generate renewable energy at low cost for the production of green hydrogen and synthetic fuels, and is therefore considered as a potential future producer and exporter. Yet, while solar and wind energy potentials are essential, other factors are expected to play an equally important role for the development of green hydrogen and synthetic fuels (export) sectors. This includes, in particular, adequate industrial capacities and infrastructures. These preconditions vary from country to country, and while they have been often mentioned in the discussion on green hydrogen exports, they have only been examined to a limited extent. This paper employs a case study approach to assess the existing infrastructural and industrial conditions in Jordan, Morocco, and Oman for the development of a green hydrogen and downstream synthetic fuel (export) sector.
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.
Real-world labs are witnessing continued growth and institutionalization in the field of transformation-oriented sustainability research, as well as in adjacent disciplines. With their experimental research agendas, these labs aim at sustainability transformations, however, there is still a need to improve the understanding of their impacts. Drawing from this Special Issue's contributions, we offer a broad overview of the impacts achieved by various real-world labs, highlight the diverse areas and forms of impact, and elucidate strategies as well as mechanisms for achieving impact. We present methodological advances, and address common challenges along with potential solutions for understanding and realizing impact.
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.
Deutschlands Haushalte werden, zu Beheizungszwecken, zu 70 % leitungsgebunden versorgt: 50 % mit Erdgas und 14 % mit Fernwärme; 5 % mit Elektrizität, davon je die Hälfte noch mit Nachtspeicherheizung, die andere Hälfte mit Wärmepumpen. So war es 2021. So wird es in Zukunft nicht sein, denn Erdgas ist ein Energieträger fossiler Herkunft. Dessen Nutzung geht in den nächsten beiden Jahrzehnten gen Null. Die Frage ist, was das für die Erdgasleitungen in Deutschland bedeutet.
