• Sustainable product offerings in food retailing have been increasing in the last years, making their way from specialized stores to mainstream food retail stores. It is the case of Germany in which sustainable food products are found in many retailing channels, even discounters. Many pieces of research have been focusing on the bio- and fair-trade labels effect on consumers' behavior, and increased interest has been put in the effect it has regarding WTP towards food products. These studies tend to conclude in a higher WTP towards sustainable labeled food products. However, the studies focus only on the valuation of the product qualities and leave the retailer format aside, which is the location where the product and the labels are being displayed and evaluated by the customer. This research will focus on assessing if the retailer format influences consumers WTP towards bio and fair-trade labels in the German food retail market. In total, 400 randomly selected participants answered one of four surveys regarding WTP towards food products in different retailer formats. Two retailer formats are considered discounters and supermarkets. This research analyses if the labels are performing adequately throughout all food retailing formats in order to provide valuable information for the future of sustainable consumption and regulation. In the end, we cannot conclude a statistically significant difference through the analysis of variance of the means of the label performance in both retailer formats.
