Consumer expectation and responses to environmental sustainability initiatives and their impact in foodservice operations: A systematic review.

BACKGROUND: With increasing pressure on the Earth's finite resources, there is significant demand for environmentally sustainable practices in foodservice. A shift to sustainable foodservice operations can decrease its environmental impact and may align with consumer expectations. This systematic review explored consumer expectations (attitudes pre-intervention) and responses (behaviour, cognitive attitudes and affective attitudes post-intervention) towards environmentally sustainable initiatives of foodservice operations. METHODS: A systematic search following PRISMA guidelines was conducted across MEDLINE, EMABASE, CINAHL and Web of Science databases. English and full-text research articles published up to November 2019 were identified. Consumers' expectations and responses to interventions were extracted. The quality of the studies was assessed using the Mixed Methods Appraisal Tool (MMAT). RESULTS: Thirty-three studies were included and, given the heterogeneity of the studies, the results were synthesised narratively. The main outcomes analysed included changes in behaviour and attitudes (cognitive and affective), including knowledge and satisfaction. Intervention strategies were interpreted and categorised into three groups: food waste reduction, single-use item and packaging waste reduction, and initiatives related to menu, messaging and labelling. Most studies resulted in significant pro-environmental changes towards decreasing food waste, decreasing single use-item and packaging waste, as well as engaging consumers in sustainable eating. CONCLUSIONS: There are a range of successful environmentally sustainable strategies that when implemented by foodservices can have a mostly positive impact on consumer attitudes and responses. However, positive consumer attitudes did not always translate to changes in behaviour. Foodservices should carefully consider implementing interventions that support changes in consumer behaviour.

Transformative systemic changes to embed environmental sustainability in foodservices: A grounded theory exploration.

AIMS: Foodservices are a strong contributor to global environmental impact. Systemic change is required to lead the transformation towards environmentally sustainable foodservices. However, guidance to support foodservices to be more environmentally sustainable is lacking. The aim was to explore food-related environmentally sustainable strategies and their transferability to foodservices in a range of settings, to inform a framework for future application and research. METHODS: A constructivist grounded theory study design was used. Semi-structured interviews with foodservice sustainability consultants, who support foodservice organisations to improve environmental sustainability, were conducted. Interviews were recorded, transcribed, and coded line-by-line. Ten consultants were purposively sampled for diversity in location, organisation type, funding model, and services provided. Codes were collapsed into categories, to inform the development of themes and a framework for the implementation of strategies. RESULTS: Four sub-themes were created under an overarching theme of 'Transforming the Foodservice System': embedding leadership, shifting perspective, constructing collaborative networks, and fostering momentum. A range of implementation strategies were captured within the sub-themes. CONCLUSION: These themes informed the development of a practical application framework for implementing sustainable strategies in foodservices that is useful for practice and future research in the area.
