The April issue of Boating featured Thetford's line of green cleaners(http://www.boatingmag.com/greencleaners). They meet the EPA's Design for the Environment standards, and are effective at cleaning the boat.

What we want to know is: What does green mean to you? Does the product have to follow the EPA's DFE standards? Or can it just consist of natural ingredients, and doesn't need any certifications? Let us know if green products are important to you, and which ones you find work the best.
