The objective was to determine the relationship between Greenhouse Gas emissions (GHG) expressed in CO2equivalent (CO2eq) and food consumption by students of Universidad Nacional Federico Villarreal. For this purpose, a survey was conducted among students in 2024 using an online form distributed via Facebook, WhatsApp Web, and email. The form included the Kilometer Food Calculator developed by Gonzalez [1] and Pérez, et al. [2] and GHG values reported by Poore and Nemecek [3]. The most consumed food groups were cereals and flours: men (M) 1.8 kg and for women (W) fruits 1.6 kg. According to Mertens, et al. [4] and Ritchie, et al. [5] the most consumed food was rice: M 2.2 kg and W 1.5 kg; finding that according to the Calculator, the estimated annual CO2eq emissions in kg (M 201.3 and W 212.0 kg) are higher than those determined (M 212.1; W 152.0) by the other authors, observing that when grouping foods, the first instrument yields lower values for other foods: M 0.2 and W 0.41; compared to those obtained from other foods reported by Poore and Nemecek [3]: M 44.8 and W 37.7. Given the variability of food groups, it is necessary to study CO2eq emissions for the foods we consume in the country.
