The project's work was conducted via 7 work packages (WPs). WP1 & 2 comprised of preparatory work including a literature review and the development and piloting of an event reconstruction instrument to capture the situational drivers of environmentally significant consumption behaviour. WP3 built the Fellow's skills through training and development opportunities. The Fellow undertook training in Multilevel modelling (University of Bristol), Experience Sampling Method (University of Maastricht), Project Management (University College Dublin) and Spatial data analysis in R (UK's Royal Statistical Society). The Fellow was also seconded to the Executive Directorate of the OECD and fed into the organisation's sustainability policies and practices. The secondment resulted in a publication on 'BI Org: Fostering a Behavioural Mindset at the OECD' in the Behavioural Economics Guide 2021 and a how-to guide on "Behavioural Science for Sustainability" with the One Planet Network. In addition, the Fellow collaborated on two research projects using multilevel analysis of day reconstruction data resulting in two publications ‘Daily Emotional Wellbeing during the Covid-19 pandemic’ published in the British Journal of Health Psychology and ‘Do economic preferences predict pro-environmental behaviour’ published in Ecological Economics. WP4 examined the situational predictors of meat and intention behaviour gaps in meat consumption. It resulted in three separate projects. The first project involved multilevel analyses of the situational predictors of meat consumption in National Nutrition survey datasets from France, Switzerland and the Netherlands. This work is reported in a Geary Institute working paper and is under review at a leading peer-reviewed outlet. In addition, primary quantitative and qualitative data were collected on the situational drivers of intention-behaviour gaps in meat consumption in a longitudinal five-wave study of a large UK sample. This work was supported by a research grant from the Alpro Research Foundation (€29,000) and resulted in two papers in preparation examining 1) the situational cues and psychological situational characteristics that are correlated with people with intentions to reduce their intake of meat desiring, eating and regretting eating meat and 2) the same group's perceptions of those situations via text responses. WP5 involved an event reconstruction study of the individual and situational correlates of single-use coffee cup consumption resulting in a paper in preparation. WP 6 involved the design of situated behavioural interventions and conducting a field trial on meat consumption in the canteens at the OECD's Paris campuses and feeding into a series of trials taking place in coffee shop chains in Gothenburg, Sweden (all trials are currently underway). WP7 was focused on disseminating the project's activities. Highlights include the Fellow contributing to a large Nutri-Web e-symposium on "Changing Behaviour: From Policy to Table", leading a working group on Behavioural Science for Sustainability as part of the UN's programme on Sustainable Lifestyles and Education, moderating a session “Green nudges to increase the circularity of plastics” of the One Planet Network Forum and hosting an international workshop on "Behaviour, Wellbeing and the Environment" (supported by a National University of Ireland grant- €5,000).
