Go to the Be a Better Planet promotion at better.yahoo.com/planet and click "Raise Your Hand". If you have already registered, you will be taken directly to the Green Pledge. If you have not registered, you can register for the promotion and then will be taken to the Green Pledge.

Remember, you'll need to take the pledge after you've registered for the Better Planet promotion. Upon completion of the Green Pledge, we'll add 100 credits to your account and send you a compact fluorescent light bulb (CFL). Limit one green pledge per promotion participant.
