Another important aspect is that the model used links GHG emissions with the cost of products, but different food categories have different prices. As a consequence, emissions and dapt secretase per cost of product represent an interesting indicator for carbon and energy intensities of each product category. These results are presented in Figs. 6 and 7. In terms of energy intensity, 90% of the products have an energy consumption ranging from five to ten MJ per € of the final price. High variability can be found in the potatoes, vegetable and fruit category due mainly to the energy consumption in the different conservation strategies (from fresh to frozen products) and the high quantity of packaging per unit of product.
