Food labels are able to support consumers in making more sustainable food choices in out-of-home consumption situations. Thereby, the effect of changing consumption behaviour depends on the format of food labels and on the information it provides. In order to assess the importance of the amount of information as well as the design of food labels displaying sustainability aspects, we test different formats of food labels using a best-worst choice design. So far, no research tested a variation of information depth while keeping label designs fixed. We find clear preferences across both dimensions. Results indicate that consumers regard labels with a higher information depth as more helpful in order to choose a sustainable meal. For the label design it became obvious that the slider-design is preferred over footprints and traffic light label design.
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.
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.
