The New York Times profiles Jack Johnson:

"At a moment of increasing eco-vigilance among rock bands, Radiohead included, Mr. Johnson stands out as a longtime beacon. “He’s an absolute environmental revolutionary,” said Ben Harper, the guitarist and singer, who has toured and recorded with Mr. Johnson. Concert promoters involved in Mr. Johnson’s coming tour will be required to buy carbon offsets, encouraged to use biodiesel equipment and guided through many other steps in a scrupulously detailed tour agreement called an EnviroRider. And the tour will support “Sleep Through the Static” (Brushfire/Universal), Mr. Johnson’s fifth album, due out on Tuesday, recorded entirely with solar energy at his home studio and a new facility in Los Angeles."

So there.
