How to Be a Green Wedding Guest

With wedding season fast approaching, we're all looking for ways to cut the carbon cost of attending four, six, ten, even twelve couples' Big Day. Keep your green ethics intact by wearing clothes you already have (even if the other guests have already seen your party dress) and dressing them up with accessories and shoes; encouraging your friends to forego favors and programs; and helping the brides you're closest to source local flowers and wine—then keep these other steps in mind to make the Big Day a little smaller.

1. Travel green. So maybe your brother decided to get married in his future wife's hometown—and it's 300 miles from your entire family. We're not suggesting you skip it, just that you choose an eco-friendly way of getting there: carpool with other local guests, or fly if you must (but purchase carbon offsets).

2. Give green. If the newlyweds are TreeHuggers themselves, then chances are they?ve already registered for gifts made of sustainable materials, available locally, or that they really, truly need. If not, don't be afraid to go off the registry and give something that you think they'll like: try a customized piece of artwork or handmade pottery. (Of course, cash is always green, too.)

3. Eat green. Even if it's not listed on the RSVP card, nearly every wedding offers a vegetarian option. Skip the rubbery chicken and overcooked filet in favor of a pasta primavera or risotto dish. Too nervous to ask the bride? Choose the fish plate instead of red meat.
