There's talk that raising the ethanol content would actually cause gas to fail CARB's own standards. There's a big seesaw debate going on between the EPA and CARB as far as what pollutants are acceptable in what amounts, and how they are caused. CARB has gone to great lengths to prove that "cradle to grave" pollution when using ethanol blends is greater than vanilla gasoline. The more ethanol we add, the worse that number gets. However, there have been credible refutations and refutes to those refutations, to the point where it's hard to tell what the truth is, but I don't believe that this will be passed.
