The closely-watched ruling was a defeat for packagers and advertisers who warned that a proliferation of differing state laws would make national advertising and distribution of products difficult and could result in less information being provided to consumers. The law was challenged on first amendment grounds and those bringing suit said they might take the case to the Supreme Court. The FTC has national green marketing guidelines and 18 states have laws regulating the use of environmental terms in advertising and labeling. California's law is considered the most strict. Words such as "recycled" "biodegradable" and "ozone friendly" may not be used on packaging unless the product meets definitions. The good news from California is that cups and hinged-lid and other plastic containers used for point-of-sale foodservice bakery goods sold directly by the manufacturer to the end user plus fresh meats fish poultry vegetables and fruits are exempt from the state's Rigid Plastic Packaging Container Law.
