"We started the Green Zebra as a way for consumers to start enjoying nearby environmentally conscious businesses," founder Anne Vollen says of Green Zebra's coupon book, which offers 300-plus pages of discounts on green restaurants, spas, travel, cultural activities, and much more. "But we've had such an enormous response from businesses and buyers alike that it's become a virtual directory of all the green-minded things the Bay Area has to offer."

Eco-friendly limo. Sounds like another term for "VW Vanagon full of hippies going to the prom," doesn't it? But in the case of SF-based Bauer's, it isn't anything close. Bauers' 120 electric, biodiesel, and compressed-propane-powered shuttles and cars may be the largest fleet of eco-friendly vehicles in the U.S., but they aren't lacking for luxury. Stretch and hybrid limo-style vehicles, including the 2007 Lexus RX 400H SUV hybrid, come equipped with leather seats, Wifi, high end CD and DVD systems, LCD monitors for presentations, and even ports to plug in your iPod or phone. That's a long way from van benches soaked with bong water.

All aboard the ecobus! This organization takes Das Frachtgut, the veggie oilfueled bus Jens-Peter Jungclaussen uses as a mobile classroom, on an ecofriendly party tour. Movie nights are all about watching modern classics and then doing some kind of relevant outdoor activity (e.g., see The Big Lebowski, then bowl outside). Dance nights turn the bus into a mobile DJ booth and an instant, impromptu club. It's fun, safe (no drunk driving, kids!), and above all, Earth friendly. *
There was a time when real estate was all about making money – and realtors were like the characters in American Beauty. Thankfully, times they are a changin’. Now you can buy or sell your house through Green Key Real Estate, the first (and only) green real estate brokerage in San Francisco. Green Key runs a sustainable business (minimizing office waste, donating a portion of profits to green building organizations, running the office on wind power) while encouraging sustainable building and remodeling. Most importantly, though, it’s experienced real estate agents linking like-minded people to each other and to the services they need.

This online superstore is like Target (or Fred Meyer, for you Pac Northwest transplants) for environmentally sound products. We’re talking organic soy wax candles (since paraffin pollutes the air), recycled glass tumblers, picture frames made of reclaimed wood, super efficient refrigerators, all-natural hardwood furniture (since pressed wood products use formaldehyde and synthetic adhesives), household cleaners, baby clothes, and so much more. Plus, the Richmond-based (but exclusively online) store maintains a list of useful articles, news, and tips about living green, as well as a directory of green service providers, from dry cleaners to long distance phone companies.

Based on the principle that if we learn about our local surroundings, we learn about our world, this non-profit strives to turn barren, ugly, or otherwise underutilized public spaces into beautiful, relevant, useful parks and gardens, called living libraries and thinkparks, using local resources – human, ecological, economic, historic, technological, and aesthetic. The public can visit one of the SF sites in Excelsior or Bernal Heights, take kids to a Living Library in- or after-school program, or get involved in a free adult green skills job training class specially designed for low income adults (and especially immigrants).
