SpaceShare Green Travel -- carpool, community building
SpaceShare Green Travel builds ride- and room-share tools for festivals and conferences. Our sister effort Verdant Event builds complete websites for conferences with greening tools integrated.
This Guide is from the city of Portland's Office of Sustainable Development. It's divided into sections on pre-event planning, recycling, and evaluation. There are three appendixes with additional resources (mostly specific to Portland,) sample vendor letters and a sample event audit.
