Innerhalb des Projektes NsB-Ress untersuchten Forscherinnen und Forscher eine Konsumform hinsichtlich seiner Ressourceneffizienz- und Diffusionspotenziale, die eine ressourcenschonendere und -effizientere Nutzung natürlicher Ressourcen verspricht. Das Credo: nutzen statt besitzen. Zum Zweck dieser Untersuchung machten sie eine Bestandsaufnahme der aktuell und zukünftig marktrelevanten NsB-Angebote, deren Ressourceneinsparpotenziale im Nachgang analysiert wurden. Durch diese Schritte sollen Erkenntnisse und Aussagen über den möglichen Ressourcenverbrauch und Reboundeffekte möglich werden. Weiterhin wurden Erfolgsfaktoren für die Diffusion von Angeboten identifiziert sowie Einsparpotenziale erschlossen, um auszuloten, wie NsB-Angebote frühzeitig ressourcenleicht gestaltet werden können. Am Ende des Projektes sollen Handlungsempfehlungen für relevante Akteure - also Politik, Wirtschaft sowie Verbraucherinnen und Verbraucher - generiert werden.
Das Projektteam zeichnet in der vorliegenden Broschüre ein differenziertes Bild, das sowohl ökologisch als auch sozial wünschenswerte und förderungswürdige NsB-Angebote aufzeigt, aber auch diejenigen benennt, die mit Reboundeffekten verbunden sein können und deshalb einer politischen Rahmensetzung bedürfen.
The article gives insights into the implementation process of sustainable management strategies in the food service sector. Furthermore, the normative requirements for sustainability in form of a mission statement, called "sustainable food services" are presented. The authors perceive this mission statement as a means to transfer current political demands (as in the SDG of the UN) into the sector. It could serve as a model for the entire food service sector to support and facilitate implementing aspects of sustainability into business practices with the help of sustainable management tools.
Sustainable out-of-home nutrition can help achieve overarching sustainability goals through a transformation in demands of consumers in this growing market. Studies indicate that individual food choice behaviours in out-of-home settings relate to a wide set of personal, social and situational factors. These factors can be influenced by various intervention strategies. In an expert meeting and a focus group we invited caterers and consumers to generate, discuss and evaluate various practical intervention ideas. Both parties largely perceive the explored ideas as useful and agree on key intervention ideas. Overall caterers and consumers state to prefer nudging strategies over information and participation interventions.
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.
