What to ask prospective caterers when you want to go green

Are you experienced with sourcing organic ingredients and beverages for large events?
Can you get the foods we want locally? (Alternately, what substitute foods can be found locally in the quantities we need?)
For foods that can’t be found certified organic, can you source pesticide-free options?
-Are you experienced at preparing vegetarian/vegan foods (or sourcing free range organic meats/sustainably harvested seafood)?
Can you provide organic, fair trade tea and coffee with our desserts?
Can you provide fair trade chocolate for our desserts?
For items that can’t be sourced with organic, local, and/or fair trade foods, will you offer us a discount if we provide them ourselves? (In the case of wine, beers, or champagne, are additional corking fees charged if we provide these items ourselves?)
Will you use cloth napkins and tablecloths, and real glasses, tableware, and silverware for all courses?
What will you do with the leftovers? (Most caterers will donate them to a charity or package them for you to take home, but you sometimes must ask.)
