Protesters outside the North American International Auto Show in Detroit say automakers aren't doing enough to cut vehicle emissions.
About 50 Michigan college students picketed the show Sunday.
Jodie Van Horn of the environmental group Rainforest Action Network says the auto show may be glitzy, but the cars aren't going far enough to combat global warming.
She says automakers must get greener to win young buyers.
Protester Cole Smith says he wants to see more electric vehicles.
Inside the show, Chrysler's vice chairman Jim Press says automakers understand that getting green is the cost of entry into the next decade.
