  1. aCalculation of greenhouse gas emissions for each food group requires more specificity than is provided in any country’s recommendations. This specificity comes from using FAO food balance sheet data [46], which provides the proportion of specific foods consumed within a food group and is based on each country’s food availability data
  2. bTotal includes GHGE of daily recommended amounts of sugar and sweeteners
  3. cTotal includes GHGE of daily recommended discretionary calories
  4. dFruit and vegetables form one group in Uruguay, so 0.18 refers to the emissions for the combined group
