Been meaning to post this for a few weeks now! Loving the idea behind Carrotmob!
It's quite simple. Convince companies to make more responsible environmental choices by agreeing to let your money do the talking.  As stated on the site:

"Carrotmob gives you the power to make the world a better place by influencing how businesses operate. Instead of organizing boycotts, we offer to spend money as a group if a business agrees to make a socially responsible change."


This is how real change gets done: Grassroots people power! Take a look at the site, and get inspired!
