Volkswagen's Clean Diesel Dilemma
Martin Winterkorn, CEO of Volkswagen Group, has just been notified that the U.S. Environmental Protection Agency and California Air Resource Board will begin investigating claims that some of the company's diesel engine vehicles have violated emissions standards. It seems that workers installed defeat devices on the vehicles, allowing them to pass emissions tests and meet the tough standards of the U.S. market. The questions students will need to answer are: Who is responsible? And Does Volkswagen take sustainability seriously or has it just been green-washing all along?
