Supplementary Data 2. Ranking of impacts by impact category and methods in the ten most commonly served commodities in NSLP.

<strong>Supplementary Data 2. Ranking of impacts by impact category and methods in the ten most commonly served commodities in NSLP. </strong> <em>This table is provided as an excel file. To construct this table, we first identified the ten most commonly served commodities in the NSLP. We then assessed the environmental impacts of these commodities using various combinations of impact assessment methods and databases. A list of the methods and database combinations is available below as SI Table 7. We then ranked the impacts of each commodity from 1 to 10 within each of the methods/database combinations. For example, using the World Food LCA Database version 3.5 and Product Environmental Footprint (PEF) impact assessment methods in Simapro, we assessed the climate impacts of producing 1 kg of apples and 1 kg of beef. Rankings were determined for each food within a given method/database combination. For this example, the rank of apple for climate impact was 2 and the rank of beef was 10. Rankings were compared using the standard deviation of rankings for each commodity and across impact categories.</em>
