摘要：Consumers have, through their food choices, a major role in bringing about more sustainable food production. However, this presupposes that differences in sustainability are communicated to consumers. Even if food products are eco-labelled and consumers are motivated to support sustainability, a number of potential barriers may prevent consumers from using the information to make sustainable choices. Six such barriers are discussed in this paper.
