Since human nutrition is responsible for about 30 % of the global natural resource use and in order to decrease resource use to a level in line with planetary boundaries, Lukas et al. (2016) proposed a re-source use reduction in the nutrition sector by a factor 2 (Material Footprint).
The catering sector needs clearly defined indicators to assess their business activities' impact on ecology, social aspects, economic value, and health status. Within the project NAHGAST two sets of indicators, called NAHGAST Meal-Basis and NAHGAST Meal-Pro were developed. The indicator sets are proposed to measure several, with sustainability-associated challenges, such as such as the ecological, social and economical effects, which may come along with the production and the consumption of a meal. Basically, the NAHGAST Meal-Basis deals with qualitative indicators, such as the amount of organic food per serving or the percentage of food wasted. This set is supposed to enable leaders to assess the sustainability of their meals and to visualize future improvements on a simplistic level. The NAHGAST Meal-Pro deals with a more sophisticated set of indicators, such as the carbon and material footprint or the cost recovery per meal. Both sets are underpinned with sus-tainable targets and elaborated as an Excel-based assessment tool, which is tested within a one-year case study. The usefulness and the limits of the tool, as well as current results of the implementation including pro-posed challenges, are discussed.
Against the background of environmental problems arising from the growing extraction of natural resources and resource depletion, achieving a sustainable development is an indispensable challenge in the twenty-first century. In this article we want to show how socio-technical and product-service innovations can change social practices - the routine doings in everyday life - and, thus, support transition of socio-technical systems. We introduce theoretical considerations on how social practice theories and the framework of the Multi-Level Perspective in transition research can be linked to better understand transition processes from a micro-macro-link perspective. We then present cases based on desk research in the field of practices in bathing, heating and nutrition to show how these have changed over the past decades. Building on this, examples of concepts for sustainable product-service-design in these areas are introduced as leverage points to change social practices in everyday life. These have been developed in research projects or design student seminar works, respectively. We argue that this implies sustainable product-service-systems should be developed in a user- and actor-integrated framework, such as Sustainable LivingLabs. The integration of users and other stakeholders into participatory co-creation processes enables tailored solutions that take actual routines and dependencies seriously into account.
Nutrition is responsible for about 30% of global natural resource use. In order to limit the negative impact the nutritional sector has on the environment and on society, the consumption and processing of foodstuffs with assumed low negative impact is an important topic in the effort of sustainable development. In professional kitchens, clearly defined indicators assessing the impact of business activities are needed in this effort. The research and development in the NAHGAST project provides groundwork that could be of important assistance in this effort. Two versions of an assessment tool, with indicators of different complexity (NAHGAST Meal-Basic and NAHGAST Meal-Pro), were developed that can be used by kitchen professionals to determine the sustainability performance of their products - the offered meal. An informed selection of indicators, and a discussion of what processes and impacts this indicator relates to in the wider context, are essential and are discussed in this paper. Furthermore, in the selection of indicators for the purpose of our research certain criteria were considered simultaneously: (1) Communicability - What information an indicator can communicate and how comprehensible this information is for different actors; (2) Feasibility and data availability - Whether there is sufficient data for an indicator to be included and whether it is realistic for companies to integrate this indicator in their daily work practice; and (3) Scientific relevance - Whether the indicator is relevant for sustainability efforts on a larger scale and for related discussions in the scientific community. Insights related to these considerations are valuable for future developments in sustainability assessment in out-of-home gastronomy. The tool has been used to evaluate a number of dishes and results are deemed meaningful. However, assessments must not be understood as an accurate measurement but as an approximation of the sustainability of meals. At the level of individual indicators, they allow a detailed analysis and targeted optimization of recipes, while the aggregated results in the form of labels can be communicated well to customers. However, deficiencies and challenges, as discovered in the application phase of the project, demonstrate research gaps in the wider context. Finally, further steps for an integration of the tool in company processes and remaining options for companies to adjust the tool are discussed.
Das Ziel der Studie erschließt sich aus der Idee, eine Übersicht über den Stand der Erkenntnisse in den Bereichen Ressourcenkonsum (t) und Ausgaben (€) sowie Zeitverwendung (h) mit Bezug auf Typologien (Wohnen, Mobilität, Ernährung) zu erhalten. Darauf basierend wurden Transitionlandkarten entwickelt, die eine offene Erschließung von Pfadveränderungen und Lösungswegen für nachhaltigere Konsumentscheidungen und Lebensstilveränderungen ermöglichen.
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.
Das Ernährungssystem steht vor einer Vielzahl von Herausforderungen, wie unter anderem: hoher Treibhausgas-Emissionen, der Gefährdung der Biodiversität, der vermehrten ernährungsbedingten Krankheiten durch unausgewogener Ernährung sowie sozial-problematischen komplexen Lieferketten. Das erfordert nicht nur eine Transformation der Agrarwirtschaft sondern auch einen Wandel in den Ernährungs- und Lebensstilen aller Konsumierenden. Digitale und technologische Innovationen zu nutzen und weiterzuentwickeln kann helfen, diese Herausforderungen zu lösen. Vor diesem Hintergrund liefert die vorliegende Studie des Wuppertal Instituts Impulse, wie die Digitalisierung dazu beitragen kann Produktion und Konsum umzugestalten und welche Voraussetzungen dafür gegeben sein müssen.
Die Studie beschreibt die Ansatzpunkte für die Digitalisierung entlang der Wertschöpfungskette. Dazu zählen die Optimierung des Ressourceneinsatzes in der Landwirtschaft, etwa mithilfe von Smart Farming, die Unterstützung von Verbraucher*innen durch digitale Tools und Assistenzsysteme - beispielsweise mit Apps als Einkaufshilfe. Daneben erlauben auch neue Geschäftsmodelle und Rahmenbedingungen eine bessere Vernetzung von Produktions- und Konsumprozessen. Dazu gehören zum Beispiel neue digitale Absatzkanäle oder Prozessstufen-übergreifend Nachhaltigkeitskennzahlen wie beispielsweise CO2-Emissionen mitzuführen und zu kommunizieren, um allen Akteur*innen richtungssicheres Handeln zu ermöglichen.
The food system faces a multitude of challenges, including high greenhouse gas emissions, threats to biodiversity, increased diet-related diseases due to unbalanced diets, and socially problematic complex supply chains. This requires not only a transformation of the agricultural economy but also a change in the diet and lifestyles of all consumers. Developing and using digital and technological innovations can help to solve these challenges. In this context, the study provides impulses on how digitalisation can contribute to transforming production and consumption and which prerequisites have to be given to achieve this.
The study describes the approaches for digitalisation along the value chain. These include optimising the use of resources in agriculture - for example with the help of smart farming - and supporting consumers with digital tools and assistance systems - such as apps designed to support grocery shopping. In addition, new business models and a better connection between production and consumption processes are also possible. This includes, for example, new digital sales channels or tracking and communicating sustainability indicators such as CO2 emissions across all steps of the value chain in order to enable all stakeholders to take reliable action.
Nachhaltige Lieferketten : global kooperative Regionalwirtschaften für Wohlstand und Resilienz
(2020)
Zwei Drittel des heutigen Welthandels gründen auf globalen Wertschöpfungsketten und Versorgungsnetzen. Rein regionalwirtschaftlich organisierte Lieferketten haben in den letzten Jahrzehnten an Bedeutung verloren. Die Auswirkungen dieser globalisierten Strukturen sind vielfältig: Zum einen haben sie beschäftigungsfördernde Effekte und wirken wohlstandsstiftend. Zum anderen existieren entlang der Lieferketten extreme soziale, ökologische und ökonomische Schieflagen.
Die COVID-19-Pandemie zeigt in erheblichem Maße, wie fragil bestehende Lieferkettensysteme sind. Der Lockdown unterbricht noch immer komplexe Lieferketten und viele Probleme der bestehenden Produktions- und Konsumweise verschärfen sich weiterhin. COVID-19 ist ein Beispiel einer der möglichen Krisen, welche die globalen und vernetzten Wertschöpfungsketten kurzfristig erschüttern kann. Andere Krisen entwickeln sich schleichender und damit weniger schnell erkennbar, wie etwa der globale Klimawandel. So unterschiedlich sie sind, haben die Krisen eines gemein: Sie zeigen die Verletzlichkeit globaler Gesellschafts- und Wirtschaftsstrukturen auf und verdeutlichen die Wirkungen globalen Handels auf die Regionen und Menschen der Welt.
Die globale Nachhaltigkeitsstrategie setzt genau hier an - sie zielt darauf ab, Unterschiede und Ungleichheit in Chancen und Lebensqualität grundlegend zu vermindern. Deshalb sollte die Umsetzung der Nachhaltigkeitsziele auf internationaler, nationaler und regionaler Ebene eine Antwort auf solche Krisen sein. Da durch die Covid-19-Pandemie zeitgleich die komplette Welt in eine Umbruchsituation gedrängt wurde, bietet die Reaktion darauf an, Nachhaltigkeit als zentrale politische Resilienz-Strategie zu nutzen.
Im Zuge der Corona-Pandemie flammte die Diskussion um resiliente Kommunen auf. Diese sollten sich stärker an regional- und kreislaufwirtschaftlichen Ansätzen orientieren, um angesichts solcher Pandemien die Versorgung weiterhin gewährleisten zu können. So wichtig und richtig die Entwicklung eigener regionalwirtschaftlicher und kreislauforientierter Ansätze im Kern ist, so wenig resilient ist es, wenn deren Entwicklung nicht unter globaler und nachhaltiger Perspektive erfolgt. Ziel sollten menschengerechte, nachhaltige und transparente Lieferketten sein, die auch bei plötzlich veränderten Rahmenbedingungen und Krisen richtungssicher die Versorgungssicherheit zur Deckung von Grundbedürfnissen und Daseinsvorsorge sicherstellen können.
Das vorliegende Diskussionspapier zeichnet als Zukunftsszenario global kooperative, kreislauforientierte Regionalwirtschaften, die weltweite Ungleichheiten in Chancen und Lebensqualität grundlegend vermindern und dabei gleichsam die natürlichen Lebensgrundlagen dauerhaft bewahrt werden.
Quantitative environmental assessments are crucial in working effectively towards sustainable production and consumption patterns. Over the last decades, life cycle assessments (LCA) have been established as a viable means of measuring the environmental impacts of products along the supply chain. In regard to user and consumption patterns, however, methodological weaknesses have been reported and, several attempts have been made to improve LCA accordingly, for example, by including higher order effects and behavioural science support. In a discussion of such approaches, we show that there has been no explicit attention to the concepts of consumption, often leading to product-centred assessments. We introduce social practice theories in order to make consumption patterns accessible to LCA. Social practices are routinised actions comprising interconnected elements (materials, competences, and meanings), which make them conceivable as one entity (e.g. cooking). Because most social practices include some sort of consumption (materials, energy, air), we were able to develop a framework which links social practices to the life cycle inventory of LCA. The proposed framework provides a new perspective of quantitative environmental assessments by switching the focus from products or users to social practices. Accordingly, we see the opportunity in overcoming the reductionist view that people are just users of products, and instead we see them as practitioners in social practises. This change could enable new methods of interdisciplinary research on consumption, integrating intend-oriented social sciences and impact-oriented assessments. However, the framework requires further revision and, especially, empirical validation.
