^aThis is an average of the GHGE in various fruit commodities, weighted by the apparent US consumption proportion of each commodity, which was calculated from FAO food balance sheet data. For each row, columns 3–5 are multiplied by each other and by the total recommendation for fruit (2 cups/d) to arrive at the contribution of that commodity to the total GHGE. All rows in the final column are summed to arrive at the overall total of GHGE for the fruit recommendation
