This study evaluates consumer perceptions of what “sustainably produced” food labels imply and estimates corresponding demand for products carrying these labels. Results suggest that the typical U.S. consumer is not willing to pay a positive premium for beef, tomatoes, or apple products labeled as “sustainably produced.” Demand is particularly sensitive to inferences consumers make regarding what a “sustainably produced” food label implies. Suggestions for future work and implications of standardizing the definition of sustainability are provided.
