The "proximity supermarket" format, both medium-sized supermarkets (smaller than 2500m2), but especially small supermarkets (smaller than 1000m), have the lowest environmental impact due to their capacity to reduce gas emissions into the atmosphere at all stages of the food distribution process: from the collection of products at their point of origin and their reception in the shop to customer access to the shop and home delivery.
These shops are often located in urban centres in close proximity to consumers' homes and workplaces, which means that the vast majority of customers shop on foot (85% if we also include large supermarkets between 2501 and 5000m2).
We relate this characteristic of supermarkets to their Scope 3 emissions linked to the impact of their customers' travel and goods transport flows.
