Tulane spends 10 percent of its food budget on local products and buys organic items, including produce, meat, and beverages. Some poultry and meats served on campus are hormone and antibiotic free, and a majority of seafood is purchased according to sustainability guidelines. Fair trade coffee is available in some locations, as well as fair trade teas and chocolate. Tulane encourages the use of reusable silverware, mugs, and containers, and the dining facilities are trayless.
