The FTC continues its active presence in the environmental claims space with 20 warning letters targeting marketers of “dog waste bags” who make biodegradability and/or compostability claims for the bags and their, er, contents. The sweep contains no surprises in terms of FTC interpretation of environmental claims and is consistent with past FTC actions against marketers of such products as waste disposal bags, plastic lumber, low-VOC mattresses, and diapers. Marketers who want to include environmental claims in their pitch to consumers should avoid stepping into something messy by paying close attention to the FTC’s Green Guides.  Please click here for the full FTC report.
