It’s designed by Adrienne and Billie Joe, it’s made of 100% recycled metal, and you can get it today when you make a contribution of $10 or more to NRDC. It’s the Green Day + NRDC dogtag! Each dogtag comes with a chain, so you can wear it around your neck, and a keyring, so you can use it as a keychain.

Your donation will help NRDC slow global warming and Move America Beyond Oil.
