California wants to take a big-picture look at decreasing carbon emissions from transportation, and in doing so, it has managed to step on some toes, mainly some ethanol producers. Since California is often a trend-setter on these type of things, this case could be a good example of what the rest of us might see in our own states down the road.
Biofuels play a big role in this, but it’s the way they’re doing it that has some people riled up. I’m a biofuel fan myself and have two vehicles (both 25-year-old-plus diesels, one of which was featured on CNN.com’s American Road Trips special) that I run on biodiesel, so I find this all quite interesting.
California's proposing a “Low Carbon-Fuel Standard” aimed at decreasing carbon, not only from tailpipe emissions but also from the overall production of fuels and their use. As part of this, it has proposed a rule limiting the use of ethanol in the strategy, mainly because it says ethanol from corn (because of its land use and impact on food crops) can have a higher impact than regular gasoline produced in the state (according to the Los Angeles Times).
Supporters of the proposal claim they aren’t trying to ban ethanol or anything; in fact, according to the fact sheet I linked to above, they’re advocating going from an ethanol blend fuel called E5 (5 percent ethanol, 95 percent gasoline) to E10 (10 percent ethanol, 90 percent gasoline) and E85 (85 percent ethanol) for flex fuel vehicles.
Mainly they’re stressing the change from corn-based ethanol to cellulosic-based ethanol (ethanol made from agricultural waste or switchgrass are cited examples), which the sheet says can have four or five times lower greenhouse gas emissions than corn.
The ethanol people don’t really like that. Tom Koehler of Pacific Ethanol told the Los Angeles Times that the proposal was a “perversion of science and a prescription for disaster.” And Wesley Clark (yes, that Wesley Clark), the co-chairman of ethanol lobbying group Growth Energy, told SFGate that in addition to bad science, it would be “bad policy to adopt a regulation that creates unfair standards” and would continue California’s reliance on fossil fuels.
If you live in California, you have until April 23 to comment on the proposal, when the Air Resources Board will vote. And I'm sure the rest of you will have plenty to say on this controversial topic. Fire away in the comments.
