WASHINGTON (CNN) -- Don't let Jack Johnson fool you. Jack Johnson makes sure his business and his concert venues are environmentally friendly. Tabbed as a "mellow rocker" by perhaps one too many publications, the chart-topping singer-songwriter has a fire within that belies his laid-back manner -- a fire that extends to his company, Brushfire Records, and his environmental activism. Johnson started the record label in 2002 "as a way to put out soundtracks for surf movies we were making," he says. "Then our friends G. Love and Special Sauce were coming to the end of their record deal with another label, and the idea came up to put out their stuff."
