The “greenest convention” means, among other things, an online “carbon calculator” so that attendees can estimate — and offset for about $12 apiece — their “carbon footprint” while here in August. Also, some 800 volunteers will be needed as part of a “Green Team” to accomplish an “85 percent waste diversion rate at the Pepsi Center and the Colorado Convention Center.” Track the greening efforts online at http://www.demconvention.com [1].
