The world's largest automotive company is celebrating Earth Day with a barrage of activities across the U.S.

GM actually started at the beginning of the year with its "Live Green Go Yellow" campaign to promote the biofuel E85. Now the various brands have launched their own activities. Saturn, for example, is sponsoring the Green Apple Music Festival in New York City, New York, U.S. And in Detroit, Michigan, GM will be at the New Detroit Science Center to discuss its fuel cell technologies.

A full listing of sponsored activities can be found at the GMability site.
