Abstract

A 2-arm randomised control trial (with and without labels) will be conducted to test the effects of an environmental label on food choices in a virtual supermarket. A sample of 130 participants will take part in two shopping tasks: 1/ selection of 3 products to prepare a home-made dish, and 2/ selection of a ready-to-eat dish. These two tasks will be repeated for two scenarios: 1/ participants will be asked to select the foods for usual meals, and 2/ participants will be asked to select the foods for environmentally-friendly meals. This experimental design will allow to compare food choices in the presence vs. the absence of an environmental label and to investigate whether the label is informative and likely to help individuals to choose more environmental-friendly food options when explicitly asked to do so.
