We assessed the consumer welfare effects of two generic food miles labels: “carbon dioxide (CO2) emission” label and “time and number of kilometers” label. Using data from a choice experiment, our results generally suggest that a mandatory labeling policy for either type of label would have a positive welfare effect. However, a label informing consumers about the time and number of kilometers the food product has traveled provides greater positive welfare effects than a label informing consumers about the amount of CO2 emission.
