For consumers to be able to make ecologically informed purchases, in order to reduce environmental impacts of their diets, they need relevant information about the environmental impact of individual products at the point of choice. The effectiveness of ecolabels has been studied in hypothetical contexts, and were found to be effective in reducing the environmental impact of participants’ food purchases. This paper reports on the results of a randomised control trial tested in a workplace cafeteria setting. The trial tested the effectiveness of implementing eco-labelling to reduce the environmental impact of purchases in worksite cafeterias catering to a broad range of customers.
