Zipcar, the world’s largest car sharing service, is hosting its first-ever Zipcar Green Confessions party. The event is designed to get people to open up and confess their environmental sins, while also letting everyone know what they are doing or are going to do to improve the environment in which we live.

We are expecting close to 1,000 people and will be using a live Twitter feed at the event to stream people’s green sins (the confessions will be broadcasted on large screens around the room). We will be using #greenconfess hash tag to have attendees’ tweets posted.
