Usually schools aren’t too keen on cell phone use. And while most schools no longer take as hard of a line as outright confiscation, you’d be hard pressed to find many that actually hand out phones to their students — fancy phones, too.

But according to a recent All Things Considered, San Francisco’s Urban School is doing just that, distributing 25 new phones to its students in collaboration with the Go Green Foundation, Nokia and AT&T. The phones are equipped with GPS technology that tracks the students’ movements, logging their location every 30 seconds and compiling the information into a route map when hooked up to a laptop. By seeing the actual trail of that quarter-mile jaunt to a friend’s house — and the carbon footprint attached to it — Go Green hopes kids will be moved to cut back on their driving.
