Pop-superstars-turned-moody-hasbeens-turned-pop-superstars Pearl Jam recently pledged to donate $100,000 to groups that focus on climate change and other environmental concerns, as a way to offset their carbon emissions. Many of the recipients are, not surprisingly, in the Seattle rockers’ home state. (Although there’s at least one local nonprofit they seem to have missed … what were they thinking?)

While the “carbon neutral” concept is trendy right now, Pearl Jam has followed this model for donations before.

Pearl Jam has aided other green causes in the past, including donating money to preserve a Madagascar rain forest to atone for environmental damage wrought by its last tour.

Vedder also recently gave an extremely large tip to his hair stylist to atone for the Mohawk hairdo he sported for their last album.
