LEEDuser has updated the Sustainable Food Purchases Tracking Sheet in our Doc Toolkit. (see above)
The spreadsheet now gives weighted (double) credit for purchases that meet more than one sustainability criteria. This matches the credit form and allows teams to more accurately track achievement. It also generates your overall percent achievement by comparing your sustainable purchases to your total purchases (sustainable and non-sustainable) so you can easily see if you're complying with the minimum credit threshold or earning exemplary performance.
