With the holidays quickly approaching, we're setting our sights on being the eco-friendliest hosts on the block. We quickly realized, though, that the rules and regulations for doing so weren't readily apparent. Here's a list of what we came up with for showing your guests how very green you can be—without pushing too much of an agenda on them.
Food
This one is easy, and required, for having an eco-friendly gathering: serve fresh, seasonal, organic, and responsibly raised or harvested food. Make your food purchases at farmers' markets and then pass along the information to your guests—you're not just serving pumpkin pie, you're serving "Local Heirloom Pumpkin Torte with an Organic Spelt Crust," or something like that. (Bonus points for your eco-friendly menu? It sounds, and tastes, all the more gourmet!) Here's another pro for your local and organics food list: fresher, seasonal ingredients will taste better with less work. For extra oomph, offer a wide selection of vegetarian options and very few meat options (if any).
Servingware
Maybe your collection of environmentally conscious plates is still small, but don't let a large gathering deter you from being green. If you're looking to purchase plates, turn to this roundup for a good green selection. Or, get a smattering of different ones (cheap!) at thrift stores or garage sales; use their unique qualities to put together a stunning table display. Don't want to wind up washing all those dishes? Opt for compostable plates, or ask guests to bring their own. A plate potluck! Or, borrow a set of servingware from a hosting pro. Chances are, you've got an aunt or acquaintance with quite the collection, and they'd be happy to loan pieces to you (unless they're throwing a party the same night, of course).
Decorations
Decorating in season is one of our favorite things, especially in the fall when squash centerpieces can go from decorations to dessert. Bring the outside in, using leaves, twigs and branches, or berries as design elements and then composting them after the party.
Drinks
With organic wine, beer, and spirit choices popping up at every turn, this one is quickly becoming a no-brainer. Even better, opt for a local micro-brew or wine made from grapes grown in your neck of the woods. And for non-alcoholic bevs, skip the HFCS-laden sodas and instead turn to organic Italian sodas or fresh-brewed teas.
Favors
Giving gifts to your guests may fall in and out of favor, but we're fans of letting our guests take a piece of the party home. Make-ahead gifts like homemade granola or even small handmade soaps or candles might be a nice addition to your party.

Shaw's Original Fir...
I recently hosted a birthday party at my home and asked around for items that I didn't already own. I live alone, so I asked one friend to bring flatware, one to bring their plates, one a punch bowl... I managed to have 12 guests and the only garbage at the end of the night was the cake box... and that was recycled.
Yay for eco-loving friends.
How do you politely ask guests to refrain from bringing mounds of plastic-wrapped wasteful toss away items? I often tell people politely to not bring anything at all, but they don't listen.
Do hit up your local Goodwill for a cute mix of plates if you have to host a party for more folks than you have dishes. You'll be surprised by the fun selection. Mix up pitchers of tea, lemonade, or cider to serve beverages or opt for highly recyclable materials like beverages in glass bottles instead of plastic disposables. Finally, I am so inspired by the pomanders in this photo! I am going to get some started tonight :-D
Emmi -I've had the same problem when I've hosted potlucks, and friends bring over bulky plastic packages of pre-cut fruits and veggies. Not only is the packaging ridiculous, but the produce doesn't taste as good as fresh produce.
I'm okay if people bring store-bought dips, baked goods or desserts (we all don't have time to slave away in the kitchen), but the plastic-wrapped produce drives me insane.
I now try to be really specific in the invite about what I'll already have at the party for people and what people should bring, and that helps.
