Greenopia™ - the urban dweller's guide to green living - began as a book of eco-friendly retailers, services, and organizations in the Los Angeles area. Advomatic was brought in to rebuild the online component for business listings, to develop the accompanying community site, and create a system allowing Greenopia to roll out additional city guides.

Advomatic also hosts the redeveloped greenopia.com. New features include a robust search interface for business listings with google maps integration, user reviews, custom content types for Feature articles, green 'tips and tools', Q & A with a Greenopia expert and various eco-friendly guides.
