Purchasing Guidelines

Purchasing Guidelines for Institutional Purchasing

In 2007, the Sustainable Food Project received a SARE grant to write an expanded set of definitions for dining halls to use across the northeast. They were published in the summer of 2008, and are a great tool for institutions considering making the transition to sustianable purchasing. Read a pdf here or email us to request a printed copy.

What is sustainable purchasing?

“Sustainable” has become a popular buzzword, but what does it really mean? The Yale Sustainable Food Project uses the word as a tool to aid in making practical decisions. We say that “a practice can be called sustainable if and only if it can be continued indefinitely without degrading the systems and resources upon which it relies.”

Deciding whether a farm or producer is “sustainable” requires care and attention. Yale students, in partnership with Yale University Dining, helped write the following standards that guide the Sustainable Food Project’s purchasing decisions. Our “gold standard” for purchasing is food that is local and sustainable. When a local, sustainable option is not available, we choose local food and then work with farmers to build that supply. When an item cannot be grown locally—bananas or coffee, for example—we choose ingredients that are certified fair trade and sustainable or certified organic from elsewhere. Each decision is meant to foster practices that sustain the health of the soil, the environment, communities, and the people producing and eating food.

The default sources for institutional dining—like many brand names found on grocery shelves—often provide uniform quality and economies of scale at a cost to taste, nutrition, environmental health, and local communities. Each year, Yale and farmers work together to increase local supply and to set fair and competitive prices for local, sustainable food. One at a time, these decisions about how what we eat is grown and processed help move Yale toward a more sustainable system.
