Greenwashing claims continue to expand, with an active plaintiff bar issuing demand letters and filing suits on subjects such as biodegradability, PFAS, heavy metals, and recycling. Legal claims on biodegradability and recycling are generally premised on the FTC Green Guides or California laws. While the Green Guides have not been updated in more than a decade, California law arguably prohibits any claim of biodegradability and regulates when composting claims may be made.
