Study title

This pilot study data was collected to test the feasibility of a new methodological approach that could help to investigate how environmental behaviour (transport behaviour, energy consumption, food consumption, goods consumption, wasting) dilemmas can be overcome on an individual level in real life by using smartphones to collect daily behavioural data in a field-experimental setup. The data includes information on the above-mentioned behaviour based on survey responses, GPS records, barcode scans and electric meter counter images. The data were collected in June 2017 daily over two weeks from 20 study participants of whom 12 were female and 8 male. Moreover, 13 were University students and 7 had a professional background. The two field-experimental interventions were implemented in the second week of data collection and included (1) behavioural targeting (individualised message nudges based on past behaviour) and (2) social monitoring (messages that allowed participants to monitor their own and others' environmental performance). The 20 study participants were randomly and evenly assigned to the two field-experimental interventions. Given the lack of a control group (due to financial limitations to include more study participants), the first week serves as a reference point for assessing treatment effects. Additional to the smartphone-based daily data, basic socio-demographic and attitudinal data were collected through an initial online survey. This data includes information on study participants' gender, age, financial situation and environmental attitudes (e.g. on climate change and recycling). Moreover, a final online survey was conducted after the two-weeks smartphone-based data collection to assess study participants' experience with the study design. The study participants were compensated with a 50 GBP Amazon vouchers for their study participation. This project is a pilot (feasibility) research project to study environmental behaviour (transport...
