Sustainability can carry over from one event to another. Intel created 400 messenger bags from large vinyl banners that had been used at a 2010 conference. The bags became giveaways at future Intel events and some were donated to schools, saving 5,500 square feet of material from landfills. "We do re-purpose other signage. The trick is to not date your material," says Lou Cozzo, Intel's corporate event marketing manager.

Communication with event guests is critical to the success of sustainability efforts. Symantec displayed a large sign near the registration area to share information about its initiatives. The company began its awareness campaign two months before the conference with articles in the event newsletter and on its Web site. In addition to the display, organizers shared information about sustainability during keynote sessions and on the event app.
