And from the fact sheet on sustainability:
Walmart is using the information from the produce Index to help growers increase crop yields, reduce inputs, lower costs and strengthen sustainable farming practices.
Suppliers are using the Index to monitor their year-over-year progress in their sustainability efforts.
TK: I'm curious as to the amount of "buy-in" for measuring sustainability there is in the fresh produce growing community, especially relative to use of the Stewardship Index for Specialty Crops - and how that data may be useful for Wal-Mart. Still a tremendously long way to go in my view, an extended period of time before buyers will be judged on how their produce suppliers meet sustainability goals.
