Der Arbeitsschritt 2.3 "Anforderungen an das kooperative Roadmapping" zielt auf die Identifizierung und Operationalisierung von Anforderungen zur Integration von Stakeholdern und Nachhaltigkeitsperspektiven ab. Hierbei wurde zum einen an die Erfahrungen aus anderen kooperativen Roadmapping-Prozessen angeknüpft, zum anderen wurden die Spezifika dieser Roadmapping-Prozesse (u.a. Positionen von Stakeholdern, Thematische Schwerpunkte) herausgearbeitet und in Anforderungen übersetzt.
Dieses Arbeitspapier ist ein Ergebnis aus dem Arbeitspaket 2 "Operationalisierung" im Rahmen des Projektes "Living Labs in der Green Economy: Realweltliche Innovationsräume für Nutzerintegration und Nachhaltigkeit" (INNOLAB), das im Rahmen der Sozial-ökologischen Forschung zum Themenschwerpunkt "Nachhaltiges Wirtschaften" vom Bundesministerium für Bildung und Forschung gefördert wird.
Die Transformationsprozesse hin zu einer nachhaltigen Entwicklung sind komplex.
Wie kann Wissenschaft dazu beitragen, dass neue Lösungen und Ideen in der Praxis zu Veränderung führen? Dieser Frage gehen die Autorinnen und Autoren am Beispiel der Gebäudeenergiewende nach. Eine transformative Forschung, die den neutralen Beobachterposten verlässt, braucht entsprechende Konzepte und Methoden: Wie kann Wissen aus unterschiedlichen Disziplinen und aus der Praxis integriert werden, um komplexe Sachverhalte und Zusammenhänge zu erklären und zu verstehen? Welche Rolle spielen komplexe (agentenbasierte) Modelle und Experimente dabei? Wie sieht der Methodenmix einer transformativen Wissenschaft aus, die Akteure bei Transformationsprozessen aktiv unterstützt? Illustriert werden diese Fragen am Beispiel des vom BMBF geförderten Forschungsprojektes "EnerTransRuhr".
The European Horizon 2020-project COMBI ("Calculating and Operationalising the Multiple Benefits of Energy Efficiency in Europe") aims at estimating the energy and non-energy impacts that a realisation of the EU energy efficiency potential would have in the year 2030. The project goal is to cover the most important technical potentials identified for the EU27 by 2030 and to come up with consistent estimates for the most relevant impacts: air pollution (and its effects on human health, eco-systems/crops, buildings), social welfare (including disposable income, comfort, health and productivity), biotic and abiotic resources, the energy system and energy security and the macro economy (employment, economic growth and the public budget). This paper describes the overall project research design, envisaged methodologies, the most critical methodological challenges with such an ex-ante evaluation and with aggregating the multiple impacts. The project collects data for a set of 30 energy efficiency improvement actions grouped by energy services covering all sectors and EU countries. Based on this, multiple impacts will be quantified with separate methodological approaches, following methods used in the respective literature and developing them where necessary. The paper outlines the approaches taken by COMBI: socio-economic modelling for air pollution and social welfare, resource modelling for biotic/abiotic and economically unused resources, General Equilibrium modelling for long-run macroeconomic effects and other models for short-run effects, and the LEAP model for energy system modelling. Finally, impacts will be aggregated, where possible in monetary terms. Specific challenges of this step include double-counting issues, metrics, within and cross-country/regional variability of effects and context-specificity.
In order to make our lifestyles sustainable, changing our consumption patterns is fundamental. Hence, we need to better understand who the "consumers" are and to consider them as an active actor to directly engage for ensuring effective policies. In order to support a resource-light society, production and consumption need to be considered through an integrated system view; within this, consumers play an important role as co-acting subjects. Almost every activity in private life involves a form of consumption aimed at satisfying the subject's needs and often regarded through an economic lens. Sustainable development is not about abolishing private consumption, but rather about making it environmentally, socially and individually sustainable in its design, organization and realization, also involving ideas of simplicity or renunciation. In this paper, we will assess the status quo of the German and European debates on Consumer Research Policies and discuss the idea to link sustainability research and consumer research - where a strategic relation is currently missing. Within that discussion, an evidence-based and obligatory consumer research strategy in Germany and Europe would represent a significant improvement. A system view perspective is necessary to take into consideration the impressive amount of diversity, and to elaborate realistic economic and consumer policies. Therefore, we propose nine steps for understanding the role of the consumer in implementing sustainable development from a scientific and political perspective. The limitations of this paper are thus a result of the very diverse and often unclear policies and agendas produced by governments. The implementation of the proposed innovative research agenda for a future-orientated and sustainability-based consumer research is not free from challenges. Still, the paper suggests the first steps towards this direction. After a critical discussion of the current EU and German consumer and sustainability policies, nine differentiated and substantial ways to integrate and ameliorate them are proposed.
The field of nutrition will face numerous challenges in coming decades; these arise from changing lifestyles and global consumption patterns accompanied by a high use of resources. Against this background, this paper presents a newly designed tool to decrease the effect on nutrition, the so-called Nutritional Footprint. The tool is based on implementing the concept of a sustainable diet in decision-making processes, and supporting a resource-light society. The concept integrates four indicators in each of the two nutrition-related fields of health and environment, and condenses them into an easily communicable result, which limits its results to one effect level. Applied to eight lunch meals, the methodology and its calculations procedures are presented in detail. The results underline the general scientific view of food products; animal-protein based meals are more relevant considering their health and environmental effects. The concept seems useful for consumers to evaluate their own choices, and companies to expand their internal data, their benchmarking processes, or their external communication performance. Methodological shortcomings and the interpretation of results are discussed, and the conclusion shows the tools' potential for shaping transition processes, and for the reduction of natural resource use by supporting food suppliers' and consumers' decisions and choice.

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.
Businesses are under increasing pressure to improve the resource efficiency of their products and services. There is a need for practical tools that enable businesses to implement resource efficiency in their value chains. In this paper, a mixed-method approach for assessing the life-cycle-wide use of natural resources in products and services is applied in a case study on a coffee value chain of the company Mars Incorporated. Material inputs along the entire chain were assessed quantitatively using the Material Input Per unit of Service method, while a semi-quantitative Hot Spot Analysis was performed to identify environmental hot spots. This mixed-method approach has been implemented for the first time in practice to assess the value-chain-wide resource consumption and environmental impacts within a specific value chain of Mars Incorporated. The paper concludes that combining the methods provides better insights into the value chain than using just one of either of the methods alone. For the company, the approach has proven to be practicable because it identifies improvement options and their value-chain-wide resource efficiency potential.
This paper presents a new household-level methodology for transition towards sustainability. The methodology includes measuring the resource use of households on a micro level, testing relevant measures towards a one-planet resource use, and developing mainstreaming options in co-operation with households and providers of services, products, and infrastructures. We use the MIPS (Material Input Per unit of Service) method to calculate the use of natural resources and concentrate on the material footprint as an aggregated indicator for the overall use of material resources. With HST (Household-level Sustainability Transition) methodology, we extend the material footprint methodology from just measuring household resource use to developing visions, conducting experiments, as well as learning and upscaling, all of which contribute to the whole Transition-Enabling Cycle. Results from the first application of the HST methodology on five households in Jyväskylä, Finland, show that it is possible to achieve a significantly more sustainable level of consumption by a relatively few changes in everyday living. Achieving a one-planet use of material resources, however, also requires systemic changes.
Sustainable supply chain management can drive sustainability. The interpretation of Sustainable supply chain management as an upstreamoriented strategy has an important, but limited potential. Addressing consumer needs and lifestyles downstream can increase the sustainability potentials of Sustainable supply chain management.
A key factor to energy-efficiency of heating in buildings is the behavior of households, in particular how they ventilate rooms. Energy demand can be reduced by behavioral change; devices can support this by giving feedback to consumers on their behavior. One such feedback device, called the "CO2 meter", shows indoor air-quality in the colors of a traffic light to motivate so called "shock ventilation", which is energy-efficient ventilation behavior. The following effects of the "CO2 meter" are analyzed: (1) the effect of the device on ventilation behavior within households, (2) the diffusion of "CO2 meter" to other households, and (3) the diffusion of changed behavior to households that do not adopt a "CO2 meter". An agent-based model of these processes for the city of Bottrop (Germany) was developed using a variety of data sources. The model shows that the "CO2 meter" would increase adoption of energy-efficient ventilation by c. 12% and reduce heating demand by c. 1% within 15 years. Technology diffusion was found to explain at least c. 54% of the estimated energy savings; behavior diffusion explains up to 46%. These findings indicate that the "CO2 meter" is an interesting low-cost solution to increase the energy-efficiency in residential heating.
Der Endbericht stellt die Ergebnisse des Projekts "Energiesuffizienz - Strategien und Instrumente für eine technische, systemische und kulturelle Transformation zur nachhaltigen Begrenzung des Energiebedarfs im Konsumfeld Bauen/Wohnen" dar. In dem Projekt wurde untersucht, wie energiesuffiziente Alltagsroutinen, soziale Praktiken und Lebensstilaspekte mit den sozialen und ökologischen Anforderungen an eine nachhaltige Entwicklung in Einklang gebracht werden können und wie die strukturellen und politischen Rahmenbedingungen gestaltet werden müssen, so dass Energiesuffizienz im Alltag akzeptabler und praktikabler wird. Für die drei prinzipiellen Energiesuffizienz-Ansätze Reduktion, Substitution und Anpassung wurden Reduktionspotenziale für den Haushaltsstromverbrauch quantifiziert. Für ausgewählte Anwendungsfelder wurden die Ergebnisse in Form von Suffizienzspektren dargestellt. Anschließend wurden Politikansätze zur Unterstützung von Energiesuffizienz in Privathaushalten analysiert und Vorschläge für ein integriertes Paket von Politikinstrumenten für Energieeffizienz und -suffizienz entwickelt. Die Erkenntnisse des Projektes sind unter anderem in einen internetbasierten Haushalts-Strom-Check, in ein Handbuch zur nachhaltigen Produktgestaltung für die Geräteindustrie und in die Entwicklung von Vorschlägen für nationale und EU-Instrumente zur Reduktion des Stromverbrauchs und zur Förderung des kommunalen Klimaschutzes eingeflossen.
Die Kreislaufwirtschaft zielt unter anderem darauf ab, Abfall als Rohstoff für neue Produkte zu nutzen. Bei Ökobilanzen von Produkten stellt sich diesbezüglich die Frage, wie sich im offenen Kreislauf rezyklierter oder thermisch verwerteter Abfall bewerten lässt. Für die Bewertung von Produktsystemen sind zwei Allokationsmethoden üblich: Die Cut-Off Methode, welche den Einsatz von Recyclingmaterialien begünstigt und die Avoided Burden Methode, welche die Abgabe von recyclingfähigem Material begünstigt. Wir diskutieren diese beiden Methoden hinsichtlich ihrer Eignung zur Bewertung einer Kreislaufwirtschaft, gemessen an der europäischen Abfallhierarchie. Als Fallbeispiel dienen verschiedene End-of-Life-Szenarien für Glas und den Kunststoff Polypropylen, die wir mit Hilfe der Umweltindikatoren Material Footprint und Carbon Footprint bewertet haben. Als Ergebnis zeigt sich, dass die Anwendung von Avoided Burden im Fall einer thermischen Verwertung in einer Müllverbrennungsanlage problematisch ist. Zum einen ergibt sich in diesem Fall ein negativer Material Footprint, falls dadurch ein Steinkohlekraftwerk substituiert wird, zum anderen wird die Abfallhierarchie teilweise übergangen, da die thermische Verwertung günstiger erscheint als Recycling. Des Weiteren wurde herausgestellt, dass die oberste Priorität in der Abfallhierarchie, die Vermeidung, durch den Cut-Off Ansatz höher begünstigt wird, als durch die Avoided Burden Methode.
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.
Human nutrition is responsible for about 30% of the global natural resource use. In order to decrease resource use to a level in line with planetary boundaries, a resource use reduction in the nutrition sector by a factor 2 is suggested. A large untapped potential to increase resource efficiency and improve consumers' health status is assumed, but valid indicators and general guidelines to assess these impacts and limits can barely be found. Therefore we will have a try to define sustainable limits towards the individuals' daily diet and therefore stimulate current available scientific debate.
Within the paper an examination of existing indicators and assessment methods is carried out. We set the focus on health indicators, such as energy intake, and environmental indicators, such as the carbon or material footprint. The paper aims to provide first, an assessment of core indicators to explore the sustainability impact of foodstuff, and second, a deeper understanding and a discussion of sustainable limits for those dimensions of food and nutrition. Therefore we will discuss several ecological and health indicators which may be suitable to assess the sustainabilty impact and indicate differences or similarities. As a result it becomes obvious that several ecological indicators "point in the same direction" and therefore a discussion about the variability and the variety of these indicators has to be faced in the future. Further the definition of sustainable levels per indicator is an essential aspect to get an idea about the needed barriers for a sustainable nutrition, by now first steps had been made, but no binding guidelines are available yet. Therefore the paper suggests a few indications to set up sustainable levels for health and environmental indicators, based on the idea to reduce the resource use level up to 30-50% in 2030.
