Description: The concept Material Input per Service Unit (MIPS) was developed 20 years ago as a measure for the overall natural resource use of products and services. The material intensity analysis is used to calculate the material footprint of any economic activities in production and consumption. Environmental assessment has developed extensive databases for life cycle inventories, which can additionally be adopted for material intensity analysis. Based on practical experience in measuring material footprints on the micro level, this paper presents the current state of research and methodology development: it shows the international discussions on the importance of accounting methodologies to measure progress in resource efficiency. The MIPS approach is presented and its micro level application for assessing value chains, supporting business management, and operationalizing sustainability strategies is discussed. Linkages to output-oriented Life Cycle Assessment as well as to Material Flow Analysis (MFA) at the macro level are pointed out. Finally we come to the conclusion that the MIPS approach provides relevant knowledge on resource and energy input at the micro level for fact-based decision-making in science, policy, business, and consumption.

Description: Increasing concerns regarding the world's natural resources and sustainability continue to be a major issue for global development. As a result several political initiatives and strategies for green or resource-efficient growth both on national and international levels have been proposed. A core element of these initiatives is the promotion of an increase of resource or material productivity. This dissertation examines material productivity developments in the OECD and BRICS countries between 1980 and 2008. By applying the concept of convergence stemming from economic growth theory to material productivity the analysis provides insights into both aspects: material productivity developments in general as well as potentials for accelerated improvements in material productivity which consequently may allow a reduction of material use globally.The results of the convergence analysis underline the importance of policy-making with regard to technology and innovation policy enabling the production of resource-efficient products and services as well as technology transfer and diffusion.​

Description: In globalen Energieszenarien spielt die Windenergie eine wichtige Rolle für den zukünftigen Strommix. Die Technologie hat sich bewährt und die Windbranche entwickelt sich zu einer reifen Industrie. Während der bisherige Ausbau der Windenergie stark von deutschen und europäischen Unternehmen bestimmt wurde, sind nun chinesische und amerikanische Unternehmen auf dem Weltmarkt weitgehend führend. Das vorliegende Buch untersucht daher maßgebende Erfolgsfaktoren der deutschen Windbranche auf dem internationalen Markt und konzentriert sich auf zwei Bereiche: Zum einen wird die Anwendbarkeit der Erfolgsfaktorenforschung - ein Konzept aus dem strategischen Management - einer kritischen Prüfung unterzogen. Zum anderen werden in einer qualitativen Analyse Erfolgsfaktoren diskutiert, die für die vergleichsweise junge Branche wichtig sind. Entscheidend ist es demnach, Lösungen, Strategien oder Technologieentwicklungen aus anderen Branchen zu transferieren (Transferkompetenz) und eine gemeinsame Technologieentwicklung in der Wertschöpfungskette (Joint Development) zu etablieren.

Description: Die systematisch-intentionale Förderung von innovativen Unternehmensgründungen aus Universitäten und Forschungseinrichtungen bedarf einer ergänzenden Neuausrichtung, will sie sich zukünftig als noch legitimierter und effizienter erweisen. Dabei wird im Rahmen einer integrativen Gründungs- und Innovationsförderung aus Universitäten und Forschungseinrichtungen eine Programmatik entworfen, die sich insbesondere in Prototypen komplexer Zukunftsinnovationen manifestiert.

Description: Aufgrund der Reform des Erneuerbare-Energien-Gesetzes soll die Förderhöhe für Strom aus Photovoltaik-Freiflächenanlagen nun wettbewerblich über Ausschreibungen ermittelt werden. Dafür muss eine entsprechende Rechtsverordnung geschaffen werden. Für die Eckpunkte eines solchen Ausschreibungsdesigns hat das Bundeswirtschaftsministerium eine öffentliche Konsultation in Gang gesetzt, zu der auch das Wuppertal Institut zusammen mit dem Fraunhofer-Institut für Solare Energiesysteme ISE und weiteren Unterstützern eine Stellungnahme abgegeben haben. Ihre Empfehlung ist, die Ressourcen-/bzw. Landnutzung von PV-Freiflächenanlagen als wesentliches Kriterium in die Förderung einzubeziehen. Vor dem Hintergrund eines erhöhten Nutzungsdrucks auf den ländlichen Raum weisen sie darauf hin, dass ihr angestrebter Ausbau zu ökonomischen, ökologischen, politischen und gesellschaftlichen Konfliktkonstellationen führen könnte. Zugleich machen sie deutlich, dass es zur herkömmlichen Technologie eine Alternative, die Agrophotovoltaik-Freiflächentechnologie gibt, ein Anbausystem zur Produktion von landwirtschaftlichen Gütern unterhalb von PV-Modulen. Sie ermöglicht die simultane Erzeugung von PV-Strom und die Produktion von Nahrungsmitteln. Folgerichtig wird empfohlen, nicht die PV-Anlagen, sondern Freiflächen-Technologien zum Gegenstand der geplanten Pilotausschreibungen zu machen. Die Ausweitung herkömmlicher Anlagen sollte sich auf unterdurchschnittlich fruchtbare Ackerflächen beschränken.

Description: There are a variety of economic and ecological benefits to increased resource efficiency. Social, institutional and technical innovations can all contribute towards efficiency increases. Companies face different hurdles in fostering such innovation. Small and medium-sized companies are subject to specific constraints that may prevent them from benefiting from innovation-induced resource efficiency improvements. Qualitative interviews were conducted among German small and medium-sized enterprises (SMEs) and intermediaries to identify barriers for resource efficiency innovations and to elaborate a policy mix at the federal level that could help SMEs to overcome these. We found five major barriers to resource efficiency innovations in German SMEs, comprising deficits in innovation culture, inter-firm cooperation along the value chain, finance, awareness and take-up of government funds. We propose a distinct policy mix as a response to this situation. The policy mix comprises the interlocking and synergistic elements of government funding schemes, innovation agents and innovation laboratories.

Description: Although there are already some qualification offers available for enterprises to support resource efficiency innovations, the high potentials that can be identified especially for small and medium sized enterprises (SMEs) have not been activated until now. As successful change lies in the hands of humans, the main aim of vocational education has to be the promotion of organisational and cultural changes in the enterprises. As there is already a small but increasing number of enterprises that perform very well in resource efficiency innovations one question arises: What are typical characteristics of those enterprises? Leaning on a good-practice approach, the project "ResourceCulture" is going to prove or falsify the hypothesis that enterprises being successful with resource efficiency innovations have a specific culture of trust, which substantially contributes to innovation processes, or even initially enables them. Detailed empirical field research will light up which correlations between resource efficiency, innovation and cultures of trust can be found and will offer important aspects for the improvement of management instruments and qualification concepts for workplace training. The project seizes qualification needs that were likewise mentioned by enterprises and consultants, regarding the implementation of resource efficiency. This article - based on first empirical field research results - derives preliminary indications for the design of the qualification module for the target groups resource efficiency consultants and managers. On this basis and in order to implement "ResourceCulture" conceptual and methodological starting points for workplace training are outlined.

Description: Die Krisen der internationalen Finanzmärkte waren 1998 noch nicht Realität, Atomkraft galt in Deutschland unter der Regierung Kohl immer noch als Zukunftsoption für die kommenden Jahrzehnte und für eine Bundespolitik in Richtung Energiewende war weit und breit kein gesellschaftlicher Konsens in Sicht. Dennoch gab es schon vor der Energiewende Projekte, die sich der Steigerung der Energieeffizienz verschrieben hatten. Mit kombinierten Einspar- und Solarkraftwerken, die an Schulen mit finanzieller Bürgerbeteiligungen entstehen, sollte der Weg zu einer umweltverträglichen Energieversorgung für vier Schulen in Nordrhein-Westfalen eingeschlagen werden. Wie der vorliegende Projektbericht zeigt, konnten die Ziele des Vorhabens erreicht werden: Steigerung der Endenergieeffizienz, verstärkte Nutzung erneuerbarer Energien und der Einsatz dezentraler Kraft-Wärme-Kopplung.

Description: The food and agricultural sector will face numerous challenges in the next decades, arising from changing global production and consumption patterns, which currently go along with high resource use, causing ecological and socio-economic impacts. The aim of this paper is to illustrate and evaluate the practical applicability of the Hot Spot Analysis methodology in the context of supply chain management in companies. The HSA is a method to identify social and ecological problems along the entire life cycle of a product. Special emphasis is put on a customized implementation in the value chain beef of McDonald's Germany. The HSA of McDonald's beef value chain shows that the main ecological problems arise in the phase of raw material extraction, whereas the main social problems can be identified in the phase of slaughtering. Finally, the paper shows potentials and shortcomings of such a customized application and how the results can be implemented in the sustainability management of a company.

Description: Critical metals are in great demand by the electrical and electronics industry, so waste electrical and eletronic equipment represents a significant source of secondary raw materials. Owing to low recycling rates and the concomitant supply risks associated with critical metals, the closure of the material cycles is highly relevant to the German economy. Losses of these metals occur from collection until their material recovery, along the entire disposal chain of waste electrical and electronic equipment. This paper develops planning criteria for the design of collection groups to achieve higher recovery amounts of such metals. The aim is to clarify what amounts of metals exist, both product-specific and on the market, how the dismantling of the products is constructed and how collection groups can be arranged with planning criteria oriented towards resource conservation. The analysis is a snapshot using the example of indium and selected products. A procedure is presented and findings identified which are transferable to various critical metals and to waste electrical and electronic equipment. The results show that grouping of products according to resource amounts and the dismantling effort enables forward-looking and resource-efficient planning of the treatment of every single collection group.

Description: 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.

Description: This paper reflects the socio-economic power of renewable energy production cooperatives for a wider energy system transformation in Germany. Energy cooperatives have turned into important supporters of renewable and decentralised energy structures, due to their strong growth since the year 2006, their participation in local renewable energy projects and their democratic awareness. The cooperative form of coordinating local renewable energy projects applies to a decentralised energy system that is managed by many smaller firms - a system concept that is preferred by the majority of German citizens. However, there is not enough knowledge to understand to what extent this organisational form is able to unify a broad group of actors in promoting a renewable energy system (societal power) and to gather capital for elaborating renewable energy supply structures (economic power). The reflection is based on an empirical assessment of all energy cooperatives that were registered in Germany before 31st December 2013. Their growth dynamic and their business approaches are discussed. A special focus lies on renewable energy production cooperatives. The study presents the development of their members, their capital, their profit and loss, as well as their investment intensity over a timeframe of three years (2010-2012). The socio-economic potential of renewable energy production cooperatives for supporting a renewable energy system is discussed against the background of empirical results.

Description: Die elektrische Energieversorgung von Kommunen wird nach einer Privatisierungswelle Ende der 1990er Jahren mehr und mehr wieder in kommunale Hand zurückgeholt und Kommunen entdecken Chancen und Möglichkeiten, die sich dadurch ergeben. In Nordhessen ist ein Trend der Rekommunalisierung erkennbar durch die Neugründung von Stadt- und Gemeindewerken zur Elektrizitätsversorgung oder deren Weiterentwicklung. Dieser Prozess wird unter anderem durch die Städtische Werke Aktiengesellschaft, Kassel angetrieben, die als Partner die Kommunen insbesondere beim Rückkauf der Stromnetze, der Gründung von eigenen Stadtwerken und dem Vertrieb von Energieprodukten unterstützen. Gleichzeitig ist seit Mitte Dezember 2013 der Energieversorger E.ON Mitte AG von den nordhessischen und südniedersächsischen Landkreisen (zurück)gekauft und als Energie aus der Mitte GmbH & Co. KG (EAM) wieder in kommunaler Hand. Vor dem Hintergrund dieser Entwicklungen untersucht die vorliegende Arbeit den Prozess der Rekommunalisierung der Energieversorgung in Nordhessen und beschreibt die damit verbundenen Herausforderungen für die Kommunen. Am Beispiel von drei Kommunalwerken in Nordhessen wird die Fragestellung untersucht, wie der Prozess der Rekommunalisierung gestaltet werden kann und welche Teilprozesse wie Netzrückkauf, Vertrieb und Erzeugung mit welchen Herausforderungen verbunden sind. Auch die Frage, welche Bedeutung die Rekommunalisierung von E.ON Mitte AG hat, wird untersucht. Um möglichst viel Wissen über die Rekommunalisierungsvorgänge von beteiligten Personen zu erlangen, wurde das Erhebungsverfahren der leitfadengestützten Experteninterviews ausgewählt. Die Auswertung der erhobenen Daten erfolgte mit der Methodik Grounded Theory.

Description: Die schnelle und umfassende Emissionsminderung in der Energie- und Kreislaufwirtschaft ist der Schlüssel für die Begrenzung der Erderwärmung auf unter 2 °C. In Deutschland werden entsprechende Politiken seit den 1990er-Jahren verfolgt, allerdings erst in jüngster Vergangenheit mit dem notwendigen Nachdruck und der notwendigen Orientierung hin zu mehr Marktmechanismen. Wesentliche Handlungsfelder sind Energieeinsparung und erhöhte Energieeffizienz, Umstieg auf erneuerbare Energien, Bepreisung von Klimagasen sowie eine Reduzierung und Schließung der Stoffkreisläufe. In allen Handlungsfeldern sind Grundlagen geschaffen, es bleibt jedoch der Großteil des Weges noch zu gehen, um Klimaneutralität zu erreichen. Für einen schnellen Fortschritt spielen neben der Überwindung der technischen, ökonomischen und organisatorischen Herausforderungen auch Verteilungsfragen und die Einbettung in internationale Maßnahmen eine zunehmende Rolle.

Description: 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.

Description: The petrochemical industry is among the most relevant sectors from an economic, energetic and climate policy perspective. In Western Europe, production occurs in local chemical parks that form strongly connected and densely integrated regional clusters. This paper analyzes the structural characteristics of the petrochemical system in Germany and investigates three particularly distinct clusters regarding their challenges and chances for a transition towards climate-neutrality. For this, feedstock and energy supply, product portfolios and process integration as well as existing transformation activities are examined. We find that depending on their distinct network characteristics and location, unique and complex strategies are to be mastered for every cluster. Despite the many activities underway, none of them seems to have a strategic network to co-create a tailored defossilization strategy for the cluster - which is the core recommendation of this paper to develop.

Description: Demand-side mitigation strategies have been gaining momentum in climate change mitigation research. Still, the impact of different approaches in passenger transport, one of the largest energy demand sectors, remains unclear. We couple a transport simulation model to an energy system optimisation model, both highly disintegrated in order to compare those impacts. Our scenarios are created for the case of Germany in an interdisciplinary, qualitative-quantitative research design, going beyond techno-economic assumptions, and cover Avoid, Shift, and Improve strategies, as well as their combination. The results show that sufficiency - Avoid and Shift strategies - have the same impact as the improvement of propulsion technologies (i.e. efficiency), which is reduction of generation capacities by one quarter. This lowers energy system transformation cost accordingly, but requires different kinds of investments: Sufficiency measures require public investment for high-quality public services, while efficiency measures require individuals to purchase more expensive vehicles at their own cost. These results raise socio-political questions of system design and well-being. However, all strategies are required to unleash the full potential of climate change mitigation.

Description: Energy performance contracting (EPC) as a market instrument has been effective in promoting energy efficiency worldwide, but it has encountered many insurmountable obstacles in rural energy management. In this study, based on the characteristics of energy management in rural areas, three EPC modes are designed and tested in 24,000 rural households. The test results show that two adapted EPC modes of local government involvement and energy payment directly from the national grid can effectively overcome the barriers encountered in the traditional EPC modes and work well under the economic and social environmental conditions in rural areas. The key to the adaptation of the traditional EPC modes is the introduction of the local government as the third party. Participation of the third party can effectively reduce and remove the barriers and risks and increase the mutual trust between the clients (households) and the energy service companies (ESCOs). Based on the testing results, this study suggests that governmental departments should formulate relevant EPC policies and technical guidelines within the rural context. This research recommends that farmers should not manage their energy services by themselves and it is suggested to out-contracting ESCOs by applying the modes developed and tested by this paper.

Description: Der Mehrwegverband Deutschland e. V. ist gemeinsam mit dem Wuppertal Institut vom Umweltbundesamt beauftragt worden, die Grundlage für eine gemeinsame Wirkungsmessung der Mehrweg-Rückgabe-Piloten in Deutschland zu legen. Ziel war es, mit Initiator*innen und Beteiligten aus Pilotprojekten deren Ansätze zur Wirkungsmessung zu teilen, zu spiegeln, weiterzuentwickeln - und auf Praxistauglichkeit zu testen. Diese Handreichung gibt einen Überblick über die Projekte, definiert die Gestaltungsdimensionen, beschäftigt sich mit der Wirkungsmessung, zeigt die Ergebnisse auf und gibt erste Empfehlungen. Basis der Erarbeitung war eine Workshop-Reihe der Pilotprojekte in München/Haar, Mainz-Wiesbaden, Hamburg/Westfield, Berlin/Friedrichshain-Kreuzberg und München/Glockenbachviertel.

Description: North Rhine-Westphalia (NRW) is the industrial center of Germany and one of the most important industrial locations in Europe. It is a key location for the energy-intensive basic materials industry like the production of steel and non-ferrous metals, (petro)chemicals, cement and lime, bricks, glass and ceramics, and paper. Around 20 % of NRW's total greenhouse emissions derive from industrial processes. By 2045, industry must achieve climate-neutrality, which requires a massive transformation effort. Technologically, this needs large-scale utilization of green hydrogen, carbon management, consequent circular economy, and climate-neutral production of process heat. Furthermore, various adjustments to the policy framework are essential.

Description: The goal of this dissertation is to facilitate the assessment of impacts from sustainable measures and projects with an emphasis on impact reporting for Green, Social or Sustainability Bonds in the Sustainable Finance market. It does so by providing analysts with the means to develop, depict, formulate, and assess a causal hypothesis between an intervention and its subsequent effects in an impact-chain, represented by desired environmental (E), social (S) or governance (G) changes. This is achieved by developing a methodology for so-called ESG Logic Models or ESG-LM, that combine heuristic Theories-of-Change with propositional logic and Bayesian Reasoning. Three research questions are investigated and responded to. Research Question 1 asks how such Theories-of-Change can be developed for any type of ESG-related issue and how the different process steps in a causal chain can be classified, hierarchised, and prioritised regarding their efficacy towards overarching sustainability goals and their plausibility. Research Question 2 studies (a) the means by which the analyst or any other interested third party might be warranted in believing the causal claims from an ESG-LM, and (b) how an ESG-LM can be improved if this credence is low. Research Question 3 then looks at the reporting of impacts themselves regarding indicator selection, indicator assessment and indicator quantification as well as the provision of information on the contributions and attributions by different actors. The dissertation draws on a variety of theories and adapts existing methods to achieve that. It operationalises concepts from empirical Sustainable Finance research and already existing impact assessment methodologies. It adapts scholarly and practitioner approaches for theory-based evaluation and applies a qualitative social science perspective towards theory-building and evaluation, while some of the assessment tools in the dissertation are grounded in Logic, Set Theory and Bayesian Epistemology. Examples for such tools include rules for the Attribution by actors, heuristics for the abduction of plausible outcome pathways, or a four-stage Argument and Decision-Tree to assess the credibility of ESG-LM claims (based on Bayes Theorem). My assessment of the entire methodology is positive overall, as it provides solutions to each of the three research areas. Limitations of the approach, and thus opportunities for further research, are the additional expertise and time required by analysts compared to the existing, and somewhat more pragmatic, solutions in the current market. However, this is outweighed in my opinion by the ability of the framework to strongly mitigate impact washing by actors in the financial markets as well as biases by analysts. Its overall methodology also provides opportunities for new research angles in the area of sustainability indicators and assessments.

Description: Die fortschreitende Digitalisierung stellt Unternehmen vor immer neue Herausforderungen und birgt gleichzeitig wichtige Potenziale, unter anderem zur Stärkung des Nachhaltigkeitsmanagements. Hierfür sind jedoch eine gemeinsame Vision und ein Nachhaltigkeitsverständnis grundlegende Voraussetzungen. Dieser Beitrag zeigt am Beispiel des EcoHub-Projekts, wie eine Visionsentwicklung mithilfe des Living-Lab-Ansatzes und der Backcasting-Methode zur erfolgreichen digitalen Veränderung in Unternehmen beitragen und das Nachhaltigkeitsmanagement fördern kann.
