It's not the biggest convention, but it is making a big impact on the environment. The Green West Expo is at the Los Angeles Convention Center this week.
"We do it here in Los Angeles because L.A. actually has the only convention center that really has a huge green initiative," said Diane O'Connor, Green West Expo. "So we're talking about renewable energy sources that are today powering the exhibit hall floor. They do recyclable water, a huge recycling program." In fact, there's no carpet on the convention floor -- all to save energy.
