The economic assessment of low-carbon energy options is the primary step towards the design of policy portfolios to foster the green energy economy. However, today these assessments often fall short of including important determinants of the overall cost-benefit balance of such options by not including indirect costs and benefits, even though these can be game-changing. This is often due to the lack of adequate methodologies.
The purpose of this paper is to provide a comprehensive account of the key methodological challenges to the assessment of the multiple impacts of energy options, and an initial menu of potential solutions to address these challenges.
The paper first provides evidence for the importance of the multiple impacts of energy actions in the assessment of low-carbon options.
The paper identifies a few key challenges to the evaluation of the co-impacts of low-carbon options and demonstrates that these are more complex for co-impacts than for the direct ones. Such challenges include several layers of additionality, high context dependency, and accounting for distributional effects.
The paper continues by identifying the key challenges to the aggregation of multiple impacts including the risks of overcounting while taking into account the multitude of interactions among the various co-impacts. The paper proposes an analytical framework that can help address these and frame a systematic assessment of the multiple impacts.
Das Fortschreiten des Klimawandels und die Schädigung der Ökosysteme machen deutlich, dass die seit Jahrzehnten international geforderte nachhaltige Entwicklung zu den wichtigsten Herausforderungen gehören.
Um die von den Vereinten Nationen in der Agenda 2030 festgeschriebenen Nachhaltigkeitsziele, den sogenannten Sustainable Development Goals (SDGs), zu erreichen, sind alle relevanten Akteurinnen und Akteure - die Politik, die Wirtschaft sowie jede und jeder Einzelne - gefragt.
Eine nachhaltige Entwicklung, die zugleich Umweltschonung, stabile wirtschaftliche und gesellschaftliche Entwicklung sowie soziale Gerechtigkeit berücksichtigt, beruht damit auf der Kompetenz oder auch der "Literacy" der Einzelnen, für sich und im Kollektiv nachhaltiges Handeln auszuüben und im gegenseitigen Miteinander fördern zu können. Doch welche Fähigkeiten sind notwendig, um nachhaltig Handeln zu können? Welche Fähigkeiten brauchen insbesondere Konsumentinnen und Konsumenten, um ihre Produktions- und Konsummuster nachhaltiger (mit-)gestalten zu können?
Antworten darauf liefert die "Literacy für nachhaltigen Konsum", die in dem vorliegenden Diskussionspapier entwickelt und vorgestellt wird.
Zur Gestaltung von tiefgreifenden Transformationsprozessen fehlen oft handlungsleitende Kompetenzen und der Mut, Strukturen aufzubrechen.
Dafür braucht es andere Lernformen und neue Räume des Lernens für nachhaltigen Wandel. Um solche zu etablieren, haben die Vereinten Nationen die Dekade des Handelns ausgerufen, in deren Rahmen zwei Projekte des Wuppertal Instituts gestartet sind: die Transformationsakademie und HumboldtN.
Der Forschungskontext der hier vorgelegten Untersuchung liegt innerhalb des in der sozial-ökologischen Forschung angesiedelten Forschungsverbundes "Blockierter Wandel? Denk- und Handlungsräume für eine nachhaltige Regionalentwicklung". Der Untersuchungsraum ist die Region "Muldemündung" in Sachsen-Anhalt. Dort, bei Dessau, mündet die Mulde in die Elbe. In dem Teilprojekt geht es um vielfältige Tätigkeiten, die, nur zum Teil als Arbeit anerkannt, in verschiedenen gesellschaftlichen Räumen stattfinden - in "Tätigkeitsräumen". Im Mittelpunkt der Überlegungen steht die Anerkennung und Bewertung der bisher vom sichtbaren Erwerbsarbeitsraum abgetrennten sorgenden und pflegenden Tätigkeiten. Denn in ihnen, so die These der Autorinnen, gibt es Fähigkeiten für eine nachhaltige Entwicklung. Verursacht wurde ihre Ausgrenzung durch abspaltende und hierarchische Konzeptionen des Politischen und des Ökonomischen. Die hier maßgeblichen Ansätze von John Locke und Adam Smith werden daher theoriegeschichtlich analysiert. Ansätze zu Konzeptionen, die diese Trennungen nicht mehr brauchen, finden sich in zwei untersuchten Praxisbeispielen, deren Auswertung jeweils spezifische kreative Potenziale für eine sozial-ökologische Transformation i. S. einer nachhaltigen Entwicklung sichtbar werden lässt - Potenziale vieler Menschen sowie der ökologischen Natur. Ihre Aktivitäten weisen auf die Herausbildung eines ganzheitlichen Tätigkeitskonzepts mit anderen Bewertungen und einer anderen "Natur der Arbeit" hin. Die Projekte stellen, analytisch gefasst, kleine neue Gesellschaftsverträge dar, über die neue, nicht trennende Konzepte von Politik und Ökonomie entwickelt werden können, die wiederum das neue Tätigkeitskonzept absichern. Gleichzeitig machen die Praxisbeispiele aber auch deutlich, wie stark neoliberale Kräfte die alten Strukturen stützen. Diese Ambivalenz wird verstärkt durch die vielfachen Schrumpfungsprozesse, denen die Untersuchungsregion ausgeliefert ist.
Im Zeitalter der Aufklärung werden mittelalterliche Naturvorstellungen von neuzeitlichen abgelöst, die von Naturbeherrschung geprägt sind. Doch weshalb mussten auf der Epochenschwelle Scheiterhaufen brennen, weshalb war die Befreiung aus dem Naturzusammenhang patriarchal angelegt? Uta von Winterfeld untersucht aus feministischer und herrschaftskritischer Perspektive "Naturpatriarchen" auf die Schattenseiten ihrer aufklärenden Absicht: Das befreite Denken eines René Descartes ist auf Kontrolle und Beherrschung der Natur angewiesen; bei Francis Bacon verdrängt das männliche Schaffen die produktive Seite einer als weiblich gedachten Natur; Giordano Bruno verweist darauf, wie widersprüchlich und ambivalent neuzeitliche Naturvorstellungen sind. Die damals entstehenden Naturwissenschaften entzaubern eine "dunkle" oder "böse" Natur - die doch zuvor von geistlichen und weltlichen Obrigkeiten in Gestalt der dunklen und bösen "Hexe" erst geschaffen worden ist. Die Frage der Naturpatriarchen nach der Methode des richtigen Vernunftgebrauchs gilt noch immer: Wie kann ein emanzipiertes Subjekt aus dem Naturzusammenhang befreit werden, ohne ihm ein anderes Subjekt, als Objekt, zwangsläufig zu unterwerfen?
2015 verursachte jeder Deutsche 628 Kilogramm Siedlungsabfall. Damit liegt Deutschland für viele Abfallströme und insbesondere für Verpackungsabfälle deutlich über dem EU-Durchschnitt. Selbst wenn die Recyclingquoten hoch ausfallen, hat die Abfallvermeidung nicht nur eine ökologische Notwendigkeit. Auch aus ökonomischer Sicht muss sie zum Ausgangspunkt einer transformativen Innovationsagenda werden.
Materialeffizienz
(2014)
Background: Global targets for reducing resource use have been set by organizations such as the International Resource Panel and the European Commission. However, these targets exist only at the macro level, e.g., for individual countries. When conducting an environmental analysis at the micro level, resource use is often neglected as an indicator. No sum parameter indicating all abiotic and biotic raw materials has been considered for life cycle assessment, as yet. In fact, life cycle assessment databases even lack some of the specific input flows required to calculate all abiotic and biotic raw materials. In contrast, the cumulative energy demand, an input-based indicator assessing the use of energy resources, is commonly used, particularly when analyzing energy-intensive product systems.
Methods: In view of this, we analyze the environmental relevance of the sum parameter abiotic and biotic raw material demand, which we call the material footprint. First, we show how abiotic and biotic raw material demand can be implemented in the Ecoinvent life cycle assessment database. Employing the adapted database, the material footprint is calculated for 12 individual datasets of chosen materials and crops. The results are compared to those of the cumulated energy demand and four selected impact categories: climate change, ozone depletion, acidification, and terrestrial eutrophication.
Results: The material footprint is generally high in the case of extracted metals and other materials where extraction is associated with a large amount of overburden. This fact can lead to different conclusions being drawn compared to common impact categories or the cumulative energy demand. However, the results show that both the range between the impacts of the different materials and the trends can be similar.
Conclusions: The material footprint is very easy to apply and calculate. It can be implemented in life cycle assessment databases with a few adaptions. Furthermore, an initial comparison with common impact indicators suggests that the material footprint can be used as an input-based indicator to evaluate the environmental burden, without the uncertainty associated with the assessment of emission-based impacts.
Resource use of wind farms in the German North Sea : the example of Alpha Ventus and Bard Offshore I
(2013)
The German government aims to obtain at least 40 percent of its electricity from renewable sources by 2030. One of the central steps to reach this target is the construction of deep sea offshore wind farms. The paper presents a material intensity analysis of the offshore wind farms "Alpha Ventus" and "Bard Offshore I" under consideration of the grid connection. An additional onshore scenario is considered for comparison. The results show that offshore wind farms have higher resource consumption than onshore farms. In general, and in respect to the resource use of other energy systems, both can be tagged as resource efficient.
Mit der Nachhaltigkeitsanleihe NRW erschließt das Land das international wachsende Segment des nachhaltigen Investments für die Kreditfinanzierung des Landeshaushalts. Ziel der vorliegenden Studie ist es, die Bewertung positiver Nachhaltigkeitseffekte für die in 2016 emittierte Nachhaltigkeitsanleihe NRW zu erproben und Handlungsempfehlungen zur Bewertung zukünftiger Nachhaltigkeitsanleihen zu entwickeln. Für eine umfassende Nachhaltigkeitsanalyse ist aufgrund der Vielschichtigkeit der finanzierten Projekte und fehlender Standards zur Bewertung sozialer Kriterien eine umfangreiche Untersuchung erforderlich, wodurch sie für eine regelmäßige und standardisierte Wirkungsanalyse zukünftiger Anleihen nicht in Frage kommt. Stattdessen verfolgt die vorliegende Studie einen pragmatischen Ansatz zur Bewertung. Der Fokus liegt auf der Evaluation der potenziellen Treibhausgas-Minderung (THG-Minderung), da deren Bewertung sich derzeit als Standard für eine Wirkungsanalyse solcher Anleihen abzeichnet. Darüber hinaus werden die nächsten Schritte für eine Weiterentwicklung der Methodik und des Indikatorensets im Rahmen zukünftiger Wirkungsanalysen aufgezeigt.
The availability of life cycle inventories is one of the biggest challenges for life cycle wide environmental assessment. There are several life cycle assessment (LCA) databases providing inventory data as well as resource and emission profiles of processes for impact assessment methods like ReCiPe or IMPACT 2002+. But the use of these LCA databases for input oriented environmental assessment is very limited as they cover only a part of all relevant input flows. The paper describes current challenges when calculating the input oriented Material Input per Service Unit (MIPS) indicators based on LCA inventory data from the Ecoinvent database. Propositions are made how to address these challenges. As a conclusion, further need of research to reach a full compatibility of LCA databases and the MIPS concept is pointed out.

A global collaborative accounting network to calculate the resource use of products and services
(2015)
The need for recycling obsolete mobile phones has significantly increased with their rapidly growing worldwide production and distribution. Return and recycling rates are quite low; people tend to keep old, unused phones at home instead of returning them for recycling or further use because of a lack of knowledge and acceptance of return programmes. Thus far, individual use and recycling behavior has not shown any trend towards more sustainable patterns. Consequently, an increased awareness is needed for the high environmental and social impact throughout the whole value chain of a mobile phone - there is simply a lack of information and knowledge regarding sustainability issues around the mobile phone. A teaching material was therefore developed in a German research project, based on the concept of the ecological rucksack, presenting comprehensive information about the value chain of a mobile phone. Its application in different schools led to an increased awareness and interest among pupils for the connection between sustainability, resources and mobile phones. Based on these research results, this paper analyses young people’s knowledge of sustainability issues linked to their mobile phones and their acceptance of more sustainable behavioral patterns regarding their mobile, including return and recycling programmes.
This article analyses drivers and barriers to returning and recycling mobile phones and their consideration in existing communication and collection campaigns.
This is an important issue based on the fact that the mobile phone market is growing rapidly. In 2015 there are nearly 7 billion global mobile cellular subscriptions. This means that, at least theoretically, everyone in the world has access to mobile communication services (ITU 2015). However, the production of mobile phones is linked to an increasing use of natural resources: the "ecological rucksack" of a mobile phone is equal to about 75 kg of resources (Nordmann et al. 2015); while the global recycling rate of mobile phones is under 10 per cent (Nokia 2008, Tanskanen 2012).
In order to adress this issue, the main factors that influence return and recycling behaviour (focussing on mobile phones) will be discussed in chapter 2 of this article. The theoretical analysis is based on the norm activation model by Ellen Matthies (2005). This analysis will be complemented by empirical data and findings generated in the research project "Return and use of old mobile phones", funded by the German Ministry of Education and Research (Wuppertal Institute for Climate, Environment, Energy/Institute for Advanced Sustainability Studies, 2012-2014). To conclude, we will identify and operationalise essential components of mobile phone communication and collection campaigns, based on the theoretical approach of Matthies, literature and empirical studies, in order to develop a set of criteria for analysing and rating such communication and collection campaigns.
The results show that economic incentives as well as education and communication play a very important role in initiating more sustainable behavioural patterns in the ICT sector. The role of emotional factors is often underestimated in the development of communication activities. In summary, successful mobile phone communication and collection campaigns require a combination of several institutional, economic, social and emotional factors.
This paper presents the educational program "Encouraging Sustainability", initiated and realized by the "Foundation Forum für Verantwortung", the "ASKO EUROPA-FOUNDATION", and the "Europäische Akademie Otzenhausen/European Academy Otzenhausen" in cooperation with the Wuppertal Institute for Climate, Environment and Energy. The goal is to intensify the public discourse on sustainability within civil society concerning options of sustainable consumption and production patterns. The innovative program consists of two parts: (1) Twelve Books About the Future of the Earth (see section 2), (2) six didactical modules (section 3): From Knowledge to Action. The educational modules focus on important topics and key issues discussed in the context of sustainability: climate change, resource use, energy efficiency, population growth, water use, securing future food supplies, biodiversity etc. The didactical materials are developed as “open learning scenarios: all materials can be linked to many communication forms and situations in a flexible manner. For the creation and realisation of the educational materials the authors have chosen the concept of Sinus-Milieus, developed by Sinus Sociovision, in order to address specific target groups (section 4). The main target groups in the program "Encouraging Sustainability" are "leading groups of society" and multipliers because of their high resource and energy consumption on the one hand and because of their skills and educational background on the other hand. In the last section of this paper (section 5) the first experiences from the implementation of the modules are presented. The authors emphasize that the broad and flexible approach chosen, should work effectively in a period in which green issues rank high in the public opinion worldwide.

LinkLab is a newly established working group under the umbrella of German Committee Future Earth (DKN Future Earth). It opens up a space to discuss relevant connections and interfaces between real-world lab research and various scientific disciplines, exploring fruitful connections and pathways for mutual learning for future sustainability-oriented research.
There is urgent need to change the way we make use of non-renewable resources, especially metals, to sustain their availability for vital technologies associated with achieving change towards sustainability, but also to minimize negative impacts and to achieve a fair distribution of the wealth and burdens associated with their production and use. Especially public actors (state governments and administrations) have recently formulated strategies as a means to guide action fostering these goals. Yet, these strategies are very different in their character, which makes it difficult to compare them and learn how to best design strategies for a given context to contribute to the necessary change. To approach this question, we analyzed 37 national mineral resource-related strategy documents worldwide concerning their contextual conditions, motivation, and objectives. Following the general inputs for transition strategies (current and target state, transition strategy), we identified four clusters of strategy documents that share similarities in their approaches and support the development of specific recommendations for future strategy design in terms of both content and process. Designing strategies with a clear structure that interlinks a systems-based description of the current state, a clear vision (oriented at sustainability principles) and a sufficiently differentiated but at the same time flexible transition pathway improves their potential to contribute to more sustainable metal production and use.
Das Wuppertal Institut hat das Forschungsformat der Reallabore
konzeptionell und praktisch entscheidend mitgeprägt. Insbesondere in den
letzten fünf Jahren erlebt dieses Format einen ungeahnten Aufschwung.
Vor diesem Hintergrund blickt der vorliegende In Brief auf die Perspektiven für die künftige Forschung in Reallaboren. Drei Forderungen sind dabei von zentraler Bedeutung:
(1) die Besinnung auf die ursprünglichen Kern-Charakteristika der Reallabor-Idee,
(2) der systematische Capacity-Aufbau für Reallabore im Wissenschaftssystem und
(3) die Etablierung von langfristiger angelegten Reallaborstrukturen.
Wissenschaft und Bildung sind zentrale Felder und ein Hebel für eine nachhaltige Entwicklung. Mit dem neu entwickelten studentischen Lehr- und Lernformat "Transformative Innovation Lab" - kurz TIL - sollen Studierende dazu befähigt werden, selbstständig transformativ zu forschen. Dazu entwickelten und testeten die Forschenden unter Leitung des Wuppertal Instituts im Projekt "Entwicklung, Erprobung und Verbreitung neuer Qualifizierungsangebote für "Change Agents" zu transformativem Lernen am Beispiel Reallabore" (EEVA) das neue Lernkonzept. Die detaillierten Ergebnisse und zahlreiche Tipps zur Umsetzung haben die Projektbeteiligten in dem vorliegenden Praxis-Handbuch zusammengefasst, das sich an Lehrpersonen sowie weitere Multiplikatorinnen und Multiplikatoren richtet.
Science and education are central fields and a lever for sustainable development. With the newly developed student teaching and learning format "Transformative Innovation Lab" - TIL for short - students are to be enabled to conduct independent transformative research. To this end, the researchers, under the direction of the Wuppertal Institute, developed and tested the new learning concept in the project "Development, testing and dissemination of new qualification offers for 'change agents' for transformative learning using the real-world laboratory approach" (EEVA). The detailed results and numerous implementation tips have been published in a practical handbook aimed at academic teaching staff and other multipliers.
The transformative research approach of Real-World Laboratories (RWL) has recently attracted attention in German sustainability science. Some definitions and understandings have been published, but guidelines and procedural quality criteria for establishing and running a RWL are still missing. To address this gap, this article has two aims. First, it aims to derive key components of RWLs from the current discourse on RWLs and similar, but more elaborated research approaches. Second, it aims to transfer these key components into a comprehensive research practice. This practice is illustrated by the RWL process in the project "Well-being Transformation Wuppertal" (WTW).
Methodologically, the article builds on a review of RWL-related approaches for collaborative, intervention-oriented research. This includes transition management, transdisciplinary process models and action research. Based on this review, eight key components for RWLs are proposed. They position RWLs as a normatively framed approach that aims to contribute to local action for sustainable development and the empowerment of change agents. The approach uses transdisciplinary methods of knowledge integration and engages in cyclical real-world interventions within certain spatial and content-related boundaries.
The components are transferred into a flowchart, detailing process steps, aims, responsibilities and overall principles for putting RWLs into practice. Thus, a hitherto missing tool for designing and running RWLs is provided. Then, the RWL in the district of Mirke, Wuppertal, is used as an empirical example to illustrate the application of the flowchart and related key components. Consecutive discussions centre on the different roles of researchers and practitioners in the research process, as well as the relevance of an underlying theory of change for effective interventions. Finally, critical reflection, application and amendment of the proposed flowchart are encouraged
Die nachhaltigkeitsorientierte Transformation von urbanen Räumen ist eine akute Herausforderung. In den letzten Jahren haben koproduktive, experimentelle, transdisziplinäre und häufig informelle Stadtwandelprojekte als Such- und Lösungsräume hohe Sichtbarkeit erlangt. Schlüsselakteure hierfür stellen - so die These - Verwaltungsvertreter:innen einer integrierten Stadtentwicklung und -planung, Wissenschaftler:innen einer transformativen Forschung sowie zivilgesellschaftliche Stadtmacher:innen dar. Die Autor:innen, verankert in diesen drei Gruppen, kritisieren die häufig nur situative Zusammenarbeit dieser drei Akteursgruppen. Ein Modell der Zusammenarbeit im Spannungsfeld zwischen Gemeinsamkeiten, jeweiligen Potentialen und herausfordernden Eigenlogiken der Akteurssysteme wird entwickelt. Darauf aufbauend wird vorgestellt, wie durch strategischen Trialog und reflexive Lernprozesse die Zusammenarbeit verbessert und die Wirksamkeit koproduktiven und experimentellen Stadtwandels erhöht werden kann.
Para lograr una transición hacia el desarrollo sostenible son fundamentales la ciencia y la educación, especialmente la educación superior. Se necesitan formatos educativos para capacitar a los estudiantes en la realización de investigaciones transformadoras. Con base en la investigación transdisciplinaria y transformadora en laboratorios del mundo real y estudios del futuro, desarrollamos un módulo de aprendizaje y enseñanza integral: el Laboratorio de Innovación Transformadora (lit). El laboratorio desarrolla cinco competencias clave y tres tipos de conocimiento necesarios para impulsar innovaciones en sostenibilidad socialmente robustas. En este artículo se presentan las principales características de este formato vivencial y reflexivo, además de un manual para facilitar el laboratorio. También se comparten y discuten los aprendizajes centrales de la implementación de este formato en programas de estudio existentes a partir de dos pruebas realizadas en dos universidades alemanas.
For achieving a transition towards sustainable development, central importance is attached to science and education, and especially higher education. Suitable formats are needed for empowering students to perform transformative research. On the basis of transdisciplinary and transformative real-world laboratory research and futures studies, we develop encompassing learning and teaching module: the Transformative Innovation Lab (til). The lab builds on insights into five key competencies and three types of knowledge needed for developing socially robust sustainability innovations. In this paper, the main features of this experiential and reflexive format are presented and linked to a handbook for facilitating the lab. Central learnings for implementing the format in existing study programmes from two test runs at two German universities are shared and discussed.
Practices of urban experimentation are currently seen as a promising approach to making planning processes more collaborative and adaptive. The practices develop not only in the context of ideal-type concepts of urban experiments and urban labs but also organically in specific governance contexts. We present such an organic case in the city of Wuppertal, Germany, centred around a so-called change-maker initiative, "Utopiastadt." This initiative joined forces with the city administration and collaborated with a private property owner and the local economic development agency in an unusual planning process for the development of a central brownfield site. Ultimately, the consortium jointly published a framework concept that picked up the vision of the "Utopiastadt Campus" as an open-ended catalyst area for pilot projects and experiments on sustainability and city development. The concept was adopted by the city council and Utopiastadt purchased more than 50% of the land. In order to analyse the wider governance context and power struggles, we apply the social-constructivist theory of Strategic Action Fields (SAFs). We focused on the phases of contention and settlement, the shift in interaction forms, the role of an area development board as an internal governance unit and the influences of proximate fields, strategic action, and state facilitation on the development. We aim to demonstrate the potential of the theory of SAFs to understand a long-term urban development process and how an episode of experimentation evolved within this process. We discuss the theory's shortcomings and reflect critically on whether the process contributed to strengthening collaborative and experimental approaches in the governance of city development.
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.
Die umfangreiche Quartiersentwicklungsanalyse des Mirker Quartiers in der Wuppertaler Nordstadt liegt nun in einer zweiten, erweiterten und überarbeiteten Version vor. Mittels eines mixed-Methods-Ansatz und auf Basis von Medien-, öffentlichen und selbst erhobenen Daten wird darin ein umfassendes Bild der Quartiersentwicklung von 2007 bis Anfang 2020 gezeichnet.
The co-operation between municipalities and civil society actors and their independent impulses for urban development are discussed under the terms of co-production and city-making. This article summarises these activities as co-productive city-making (koSM). Forms of as well as advantages and disadvantages of koSM have been discussed in research and practice so far, but analyses of the longitudinal genesis of these activities and their significance for the development of a specific area are rare. This article uses the longitudinally collected, mixed-method data of a constellation analysis of the development of the Mirke neighbourhood in Wuppertal/Germany. Based on four points in time, the dynamics as well as the spatial development of the koSM can be presented - individually and in comparison to other developments. It can be seen that the koSM in the Mirke has grown at an above-average and dynamic rate and can accordingly be interpreted as a motor of neighbourhood development. Main actors and locations are identified. The study is the basis for a follow-up work analysing the reasons and structural effects of the koSM. The koSM is discussed both in its interrelations with municipal action and in its significance for integrated and sustainable urban development. The method of constellation analysis is critically discussed with regard to the relationship between effort and benefit.

Der Reallaboransatz hat seit seinem Aufkommen 2012 einen richtiggehenden Boom erfahren. Reallabore sind in ihrem originären Ansatz als Experimentierräume, Forschungsmodus und methodologisches Werkzeug konzipiert, um zu nachhaltiger Entwicklung und gesellschaftlicher Transformation beizutragen und diese zu beschleunigen. Wesentlicher Ansatzpunkt ist dabei, Wissenschaft und Praxis in transdisziplinären Settings und transformativen Prozessen eng miteinander zu verknüpfen. Die Wissenschaft bzw. die Forschenden, begeben sich dabei selbst in Wandlungsprozesse: Sie initiieren, experimentieren und beforschen zugleich. Praxisakteure setzen dabei Themen und forschen aktiv mit, so dass im Idealfall sowohl wissenschaftliche Theorie als auch gesellschaftliche Praxis von den Ergebnissen profitieren. Die Ausgestaltung von Reallaborprojekten hat in den letzten zehn Jahren eine Vielzahl von Differenzierungen in Inhalten, Settings, Methodik und Ausrichtung erfahren.
Die Konferenz "Nachhaltig wirken: Reallabore in der Transformation", die am 2. und 3. Juni 2022 in Karlsruhe stattfand, griff diese Entwicklungen auf, um gemeinsam mit der wachsenden Reallabor-Community den aktuellen Entwicklungsstand des Reallaboransatzes abzubilden. Organisiert vom Karlsruher Transformationszentrum für Nachhaltigkeit und Kulturwandel (KAT) in Zusammenarbeit mit den Gründungsinstitutionen des Netzwerkes Reallabore der Nachhaltigkeit, wurden auf der Tagung aktuelle methodische, konzeptionelle, praktische wie auch strategische Fragen aufgeworfen und diskutiert. Mit über 300 Teilnehmenden und 115 Beiträgen stellt sie die bislang größte und umfassendste Veranstaltung im Bereich der deutschsprachigen Reallaborforschung dar.
Citizen science is a transdisciplinary approach that responds to the current science policy agenda: in terms of supporting open science, and by using a range of science communication instruments. In particular, it opens up scientific research processes by involving citizens at different phases; this also creates a range of opportunities for science communication to happen This article explores methodological and practical characteristics of citizen science as a form of science communication by examining three case studies that took different approaches to citizens' participation in science. Through these, it becomes clear that communication in citizen science is "always" science communication and an essential part of "doing science".
The German government has set itself the target of reducing the country's GHG emissions by between 80 and 95% by 2050 compared to 1990 levels. Alongside energy efficiency, renewable energy sources are set to play the main role in this transition. However, the large-scale deployment of renewable energies is expected to cause increased demand for critical mineral resources. The aim of this article is therefore to determine whether the transformation of the German energy system by 2050 ("Energiewende") may possibly be restricted by a lack of critical minerals, focusing primarily on the power sector (generating, transporting and storing electricity from renewable sources). For the relevant technologies, we create roadmaps describing a number of conceivable quantitative market developments in Germany. Estimating the current and future specific material demand of the options selected and projecting them along a range of long-term energy scenarios allows us to assess potential medium- or long-term mineral resource restrictions. The main conclusion we draw is that the shift towards an energy system based on renewable sources that is currently being pursued is principally compatible with the geological availability and supply of mineral resources. In fact, we identified certain sub-technologies as being critical with regard to potential supply risks, owing to dependencies on a small number of supplier countries and competing uses. These sub-technologies are certain wind power plants requiring neodymium and dysprosium, thin-film CIGS photovoltaic cells using indium and selenium, and large-scale redox flow batteries using vanadium. However, non-critical alternatives to these technologies do indeed exist. The likelihood of supplies being restricted can be decreased further by cooperating even more closely with companies in the supplier countries and their governments, and by establishing greater resource efficiency and recyclability as key elements of technology development.
Für die Umsetzung der Energiewende und speziell den Ausbau erneuerbarer Energien sind nicht nur energiewirtschaftliche oder Klimaschutz-Kriterien maßgeblich. Zu einer umfassenden Nachhaltigkeitsbewertung gehört unter anderem auch die Ressourcenbewertung. Hier ist unstrittig, dass die Gesamt-Ressourceninanspruchnahme eines Energiesystems generell erheblich niedriger ist, wenn dieses nicht auf fossilen, sondern auf erneuerbaren Energien basiert (und dabei nicht hauptsächlich auf Biomasse ausgerichtet ist). Bisher wurde jedoch insbesondere der Verbrauch und die langfristige Verfügbarkeit der mineralischen Rohstoffe, die in der Regel zur Herstellung von Energiewandlern und Infrastruktur benötigt werden, wenig untersucht.
Im Rahmen des Projekts KRESSE wurde daher erstmals analysiert, welche "kritischen" mineralischen Rohstoffe für die Herstellung von Technologien, die Strom, Wärme und Kraftstoffe aus erneuerbaren Energien erzeugen, bei einer zeitlichen Perspektive bis zum Jahr 2050 in Deutschland relevant sind. Die Einschätzung als "kritisch" umfasst dabei die langfristige Verfügbarkeit der identifizierten Rohstoffe, die Versorgungssituation, die Recyclingfähigkeit und die Umweltbedingungen der Förderung. Die Studie macht deutlich, dass die geologische Verfügbarkeit mineralischer Rohstoffe für den geplanten Ausbau der erneuerbaren Energien in Deutschland grundsätzlich keine limitierende Größe darstellt. Dabei kann jedoch möglicherweise nicht jede Technologievariante unbeschränkt zum Einsatz kommen.

In the aftermath of the controversy on genetically modified organisms it has become clear that in order to harness new technologies for economic and social benefit, a wide range of social, ethical and regulatory concerns need to be addressed. This document summarises some key results from Nanologue, a project that brought together leading research and opinions on the social, ethical and legal implications of nanotechnology applications (NT) in Europe. The document presents information about the project's findings of "societal aspects of NT", based upon the results from interviews with NT scientists and researchers. Insights gained during the project have been translated into future scenarios as well as into an internet-based support tool for NT researchers and product developers called NanoMeter. The scenarios as well as the NanoMeter are briefly introduced and conclusions drawn.
