Global Exchange and Green America partnered to create greenfestival™, the "world's largest sustainable living event." Upcoming Green Fests include the DC and San Francisco events listed below, along with 2009 festivals in Seattle (March 28-29), Denver (May 2-3), and Chicago (May 16-17). Attend one of these events to meet over 300 eco-friendly businesses, listen to environmental speakers, hear great music, watch green films, and enjoy kids' activities (like making a Green Kids Earth Badge or a sock puppet).
greenfestival™ is committed to having a small environmental footprint. They claim to recover 97% of all show waste, using techniques such as providing biodegradable plates & utensils, composting food waste, providing recycling containers, off-setting electricity emissions, and banning plastic water bottles in favor of jugs of water.
Want to volunteer? Work at least 4.5 hours and you'll receive free admission each day, a free T-shirt ("limited edition, organic and sweatshop-free"), and more!
