What exactly would it take to get you to green your commute? The answer turns out to be: a lot. A new study out by the Brookings Institution shows that, while there's been a slight uptick in public transit ridership, over three quarters of Americans still get to work by driving themselves alone in their cars.
Brookings' Bruce Katz explains which regions have the worst commuter offenders and who's doing a little better at making their commute environmentally friendly. And Steve Dutch, Professor of Applied and Natural Sciences at the University of Wisconsin Green-Bay, gives us his theory as to why Americans won't surrender their keys for the bus, train or even an occasional carpool.
