We make the biggest environmental decisions each day by choosing where we spend our dollars. What if the stores that we shop at every day had added incentive to go green?

Enter VIV.

An innovative startup in San Francisco, VIV is attempting to help businesses better understand the wants of their clients - namely to encourage them to go green. It's simple. Encourage your local shops to sign up with VIV - creating a "Green Action Schedule" - a list of doable greening goals such as replacing lights with CFL's, switching paper towels to recycled content, switching to earth friendly non-toxic cleaning products - that the company will follow through with once enough Viv stickers have been counted.

Enter you: Put a cute green viv sticker on your credit card, and shop in your local businesses. Every time you go into a business that is signed up with VIV, they swipe or scan your card, and get closer to completing their green actions. And, while you are at it, encourage your favorite shops to participate.

It's a simple, creative idea that hopefully can inspire some positive change. So far it's only in San Francisco, but hopefully they will start expanding soon. Ask VIV to expand to your city.
