Green isn't just one of USF's school colors, it's also the direction the university is taking with the signing of the American College & University Presidents Climate Commitment. President Judy Genshaft (right) signed the agreement at the recent "Going Green Tampa Bay Expo," where Bay area businesses and residents got a chance to learn about the newest energy saving ideas and devices. University Beat takes you to the Expo and tells you more about USF's commitment to become more "sustain-a-Bull."
