The environmental label was developed using Life Cycle Assessment, an analysis that consider environmental impacts throughout a product’s life cycle – from field to plate. Thanks to this multi-criteria approach, Casino came up with an Environmental Index which takes into account greenhouse gas emissions, water pollution and water consumption. It compares the impact of 100g of product to the total daily food consumption of a French person. Inspired by the already existing nutritional index, consumers are familiar with this kind of labelling.
