The Federal Trade Commission (FTC) has issued an advance notice of proposed seeking public comments on proposed labeling requirements for alternative fuels and alternative-fueled vehicles. Specifically, the FTC seeks comments on the proposed Alternative Fuels Rule and whether it should (i) consolidate its alternative-fueled vehicles labels with fuel economy labels required by EPA and the National Highway Traffic Safety Administration, (ii) add new definitions for alternative-fueled vehicles contained in recent legislation and (iii) change labeling requirements for used alternative-fueled vehicles. The agency will accept comments until July 25, 2011.
