The present intervention study investigated whether providing information about how consumers can help mitigate environmental and social problems through everyday purchasing decisions can (a) strengthen consumers’ intentions to purchase sustainable groceries (e.g., ecological and fair trade foods), (b) promote actual purchases of sustainable groceries, and (c) strengthen self-efficacy beliefs in the domain of sustainable development (the assumed determinant of sustainable consumption). The results suggest that the intervention strengthened consumers’ intentions to purchase domestic, seasonal, and certified ecological products. In addition, the intervention promoted the actual purchasing of certified ecological and fair trade products. Effects of the intervention on self-efficacy beliefs were, however, nonsignificant. We discuss whether increased knowledge and consciousness might have accounted for some of the observed effects on purchasing intentions and actual purchases of sustainable groceries.
