This work therefore aims to assess the environmental, economic and nutritional quality dimensions of the menus consumed across the Local Network of School Canteens in the municipality of Ames (Galicia, Spain).

To this end, this study considers the following indicators: a) those obtained from an energy and carbon life cycle assessment of the school menus (cradle-to-grave approach), mainly the cumulative energy demand (CED) and the carbon footprint (CF), complemented by some energy efficiency indicators; b) the total cost (TC) of the menus, obtained from their life cycle cost assessment (cradle-to-fork approach); and c) the nutritional quality of the menus, calculated and assessed based on the nutrient rich diet index (NRD 9.3).
