Strict regulations on diesel emissions that the California Air Resources Board approved in December 2008 are coming under renewed fire. At the time, members of the trucking industry and others complained that CARB was acting all Chicken Little and exaggerating how bad the diesel emissions were for human health. Since then, it turns out, one of the scientists involved in the study that detailed the negative health effects misrepresented his credentials. Instead of getting his Ph.D. in statistics from the University of California Davis, Hien Tran actually got a mail-order Ph.D. from a "university" based at a mailbox at a UPS office in New York City.
This is all according to the San Diego Union-Tribune, which also says that CARB knew about the misrepresentation before their vote to approve the diesel regulations but did not reveal the information. From the looks of it, those regulations may need to be dialed back because the legitimacy of the rule is in question, says board member John Telles. Thus far, CARB chair Mary Nichols (pictured) has not been willing to admit that there is a problem, but she may be forced to change her mind and let science beat secrecy.
