Abstract: The interactive public exhibition ‘The Art of Living the Good Life’ was developed with the goal of identifying potential relationships between socioeconomic profiles, environmental awareness, and the environmental impact of nutritional choices. Visitors are guided through the exhibition using a web app and are asked questions about their lifestyle and outlook on various topics, which allows categorisation into one of twelve socioeconomic profiles according to Stelzer & Heyse (2016). They are also asked about their dietary, housing, and mobility habits, and about their environmental awareness. Based on the frequency of meat, milk and yoghurt, cheese and quark, wine, and coffee consumption and how regularly visitors waste food, the nutrition-related environment impact is calculated using the ecological scarcity method (Frischknecht et al., 2013). After answering the questions, visitors receive detailed information on their environmental impact as well as personalised tips, customised for each profile, explaining how they can reduce their impact. The median yearly environmental impact resulting from nutrition varied between socioeconomic profiles, ranging from 2.9-3.3 million eco-points per person. The difference between groups is not particularly large, but there is a considerable difference between individuals: there is an almost three-fold difference between the lowest and highest nutrition-related impact. Visitors with the lowest nutrition-related impacts tend to consume little to no meat, milk products, wine, and coffee and rarely waste food and those with high impacts consume these products more frequently and waste food more regularly. The nutrition-related impact is higher for omnivores than for vegetarians and vegans. The environmental impact resulting from nutrition tended to be slightly lower for environmentally aware participants and female visitors tended to have slightly lower nutrition-related environmental impacts than males. There are only small differences in the nutrition-related environmental impact of the socioeconomic groups, but a large range within the groups, indicating that other factors play a larger role. The large range of impacts resulting from nutrition indicates that there is significant improvement potential in this area.
