Strength2Food research on the economic, environmental, and social performance of certified food supply chains has been published in Ecological Economics. The paper covers 25 indicators of economic, environmental and social performance, estimated for 52 food supply chains. Supply chains with certifications like organic, and geographical indications, such as Protected Designation of Origin and Protected Geographical Indication, are compared against non-certified equivalents. The analysis, led by Valentin Bellassen, found that the average performance of certified food is higher than non-certified equivalent chains on most economic and social indicators. This includes operating margins for farmers, the quality and quantity of jobs created, and local multiplier effects. However, the environmental performance of certified and non-certified food chains is more mixed and for many indicators broadly similar.
