Caloric intake was varied from 1,786 to 3,782 kcal•capita -1 •day -1 representing the lowest caloric intake in the dataset (Central African Republic) in the contextual parameter dataset and the highest (United States). Similarly, animal protein intake was varied from 6.55 to 104.98 g•capita - 1 •day -1 representing the lowest animal protein intake in the dataset (Ethiopia) and the highest (Iceland). When varying the two dietary intake parameters, the alternative Biogenic Refinery annual per capital CIs ranged from 14.1 to 18.5 kg CO2 eq•capita -1 •year -1 with animal protein intake significantly impacting the emissions and caloric intake having less of an impact (Figure ). On the other hand, the CI scores for the alternative NEWgenerator and Reclaimer were more impacted by caloric intake than animal protein intake with the NEWgenerator and Reclaimer emissions ranging from 51.7 to 76.2 and 137.1 to 214.3 kg CO2 eq•capita -1 •year -1 , respectively (Figures ). Although the NEWgenerator and Reclaimer CIs results visually appear to have a slight inverse relationship between animal protein intake and emissions, no correlation exists between GHG emissions and animal protein intake for these two systems, and any inverse relationship observed is (in part) due to noise in the uncertainty analysis (the Spearman's rho for animal protein and CI scores had both positive and negative values across countries, but all were close to zero; Figure ). Although dietary intake is outside of the control of sanitation developers, these trends can be useful in determining the performance of systems in different subnational settings and highlights the need for location-specific analyses to understand whether the systems, in their current design, have the ability to meet emissions performance goals.
