The document discusses the FTC's Green Guides, which were revised in 2010 and 2012 to regulate environmental marketing claims. The guides address general environmental claims, seals and certifications, new terms, and clarifications of existing terms. As a case study, the document discusses gDiapers, which claimed to be "green" but did not adequately qualify or substantiate the claim. Finally, the document provides examples of specific claims addressed by the guides, such as compostable, degradable, free-of, non-toxic, and recycled content claims.
