Greenbook is a facebook application aimed at reducing CO2 emissions in the air.
From the “How it Works” page, “Each month we use funds generated through sponsorship to purchase an amount of CO2 reduction.” The thought is, through the establishment of an active and large community on greenbook, more corporate sponsorship money will be generated for greenbook, who in turn invests this money into reducing the CO2 in the atmosphere.
The way greenbook supports and sustains this community, which currently has “8,618 daily active users,” is similar to a facebook group with several added features only available through a facebook application. The application utilizes many “group” features such as the ability to invite friends, a discussion board, and a wall for people to post reviews of the application. The application also has an area for users to post their “Green Ideas” to help reduce energy consumption and also allows users to “Send Free Trees” to fellow users. Users can customize this application to show a “greenbook box” in their profile which shows how much that user has contributed to CO2 reduction.
Greenbook has opened a dialogue with its users about ways to reduce energy consumption, and through its corporate sponsorships is able to directly reduce CO2 emissions. This is an effective combination for an admirable cause, and since greenbook is a facebook application, it has placed itself in a position for its community to grow steadily, in terms of both numbers and effectiveness. Several of my friends have added the greenbook application, and I may be soon to follow.
