Environmental protection is not only outdoors but also on the plate: The impact of connectedness to nature on sustainable diets

Data derive from two independent studies. Study 1 employed a cross-sectional questionnaire (N = 324) that included a self-developed "Sustainable Diets Scale," the Connectedness to Nature Scale, and the Prosocial Tendencies Scale.

Study 2 was a behavioral experiment (N = 162) that recorded vegetarian choices, clean-plate behavior, and use of green tableware. The dataset contains original questionnaire responses, behavioral coding files, statistical result tables, and associated analysis scripts. Potential uses include validating theoretical models of sustainable diets, conducting cross-cultural comparisons, designing behavioral interventions, and supporting teaching or empirical research in environmental psychology and health behavior.
