The authors regret to inform that there is a typing error when citing “Dougherty et al., 2019”. In the section “These authors evaluated – through an LCA assessment – the environmental impact of five different production systems. The results from the LCA showed that carbon footprint ranged from 3.9 to 30.6 kg CO2e/kg meat, when considering a lamb production on a mass basis, and between 10.4 and 18.1 kg CO2e/kg meat, when considering lamb production on an economic basis.” There appears to be a typing error by showing 3.9 kg CO2e/kg meat rather than 13.9 kg CO2e/kg meat, which is the result found in their study. Also, the aforementioned results from “Dougherty et al., 2019” were not expressed per kg of meat but per kg of live weight to be comparable with the results of other studies. Finally, in the section “In addition, vegetarian and vegan diets had the lowest carbon footprint (55 and 1015 kg CO2eq, respectively)” from “Veeramani et al., 2017” a mistake was found. The correct sentence should be “In addition, vegan and vegetarian diets had the lowest carbon footprint (955 and 1015 kg CO2eq, respectively).
