Dealing with waste is a constant challenge for brands that make anything for the outdoors. Tent maker Nemo had a brainstorm, and came up with a great use for its tent leftovers: the Ditto Wallet. Made from old tents and factory floor fabric scraps, as well as manufacturing seconds from Nemo's tent fabric supplier, the Ditto has a billfold, three credit card pockets, a clear license window pocket, a storage pocket and a zip change pocket. A Velcro strap wraps the outside folds over to keep cards from falling out without adding bulk. Mine is translucent white/silver/gray with black diamonds of fabric reinforcement--subtle and techy looking. Here's a pic--though it's even better in person.
The Ditto is standard men's wallet size, though not just for dudes, and will tuck into a purse, back or front pocket (but carry it up front--it's better for your back). We don't know it's carbon footprint, but at .6 ounces of mostly recycled material, we're guessing it's low. Get one for yourself if you're flexible on color. Wallets come in green, gray, orange and yellow, mostly with black interior, but each one is unique. 8.4" x 3.5" (L x W open); 4.2" x 3.5" packed size. $18, nemoequipment.com.
