A strong link between emotions and eating behavior has been previously found, however there is a lack of research investigating how emotions influence food product choice in a retail setting. An online questionnaire including a choice-based conjoint analysis and self-reported consumer emotions was used to assess the importance of different product attributes to yogurt consumers in Germany in 2021. The analysis consisted of a Hierarchical Bayes approach and a cluster analysis. The results revealed that yogurt consumers placed most importance on ingredients, followed by price, Nutri-Score, flavour, and finally production method. Based on the self-reported consumer emotions, a positive, a rather positive and an indifferent emotion cluster was found. The positive cluster preferred the highest quality in terms of ecological and health values and was willing to pay more for such a yogurt. The rather positive cluster preferred these options as well, however was not always willing to pay more for them. The indifferent cluster was more driven by lower prices and was more willing to trade other qualities for the cheapest option. These findings are insightful for food marketing and health interventions as shopping experience, as well as product choice could be enhanced through emotion induction.

The greatly increased global use of plastic has serious negative environmental consequences. This study aims to analyse the influence of environmental attitudes, personal norms, social norms, and socioeconomic and demographic characteristics on consumers’ intention to reduce plastic packaging in different groups of fast-moving consumer goods (FMCGs) in Germany. Data on plastic packaging use for food, clothing, cosmetics, cleaning goods, and furniture were collected from 299 German families in a four-stage survey. The findings show differing consumer intentions to reduce plastic packaging between food products and other FMCG. In particular, environmental attitudes can differentiate between consumer groups with high and low intentions to reduce plastic packaging in nearly all the product groups analysed, while social norms, gender and age only show statistically significant differences in some product groups. Personal norms did not contribute to group differentiation in any of the groups of FMCG analysed. The results are helpful for managers of FMCGs to develop more ecological packaging solutions in the future and for state authorities to derive political activities in this field.

Although greenhouse production is an especially intensive form of agricultural production, horticultural products have not been subject to many carbon footprint studies. This study examines the poinsettia, a relevant greenhouse plant in the market. It analyzes the poinsettia’s climate impact by undertaking a product carbon footprint (PCF) study, along the whole poinsettia value chain; this starts at the mother-plant farms in Uganda, goes through the production in German greenhouses, and ends with the disposal of the plant by the consumer. A life cycle inventory was conducted, including input materials, equipment, cultural practices, and other processes used in two horticultural farms. A standardized questionnaire collected consumer data. The PCF for the poinsettia is 0.69 kg of carbon dioxide equivalent (kg of CO2e), including distribution. As heating in both investigated farms is conducted via renewable energy, major contributors to the PCF were overhead electricity, substrate, pot, and packaging. The consumers’ contribution varies from 0.31 (best), through 0.45 (average), to 1.49 (worst) kg of CO2e, and is mostly due to differences in shopping behavior, producing a total PCF of 1.0–2.18 kg of CO2e. The results show a high variability for emissions along the value chain, due to different input factor choices on the production side and a significant consumer contribution.
