"U.S. corn-based ethanol worse for the climate than gasoline, study finds"

Blame Al Gore. I'm not kidding.

Even though he later recanted,* his efforts put the imprimatur on the entire mess:

"I was also proud to stand up for the ethanol tax exemption when it was under attack in the Congress -- at one point, supplying a tie-breaking vote in the Senate to save it. The more we can make this home-grown fuel a successful, widely-used product, the better-off our farmers and our environment will be."

Third Annual Farm Journal Conference, December 1, 1998

AND four years earlier:

WASHINGTON, Aug. 3— With a tie-breaking vote by Vice President Al Gore, the Senate upheld today an Environmental Protection Agency rule requiring that ethanol and other renewable fuels get a share of the gasoline additives market.

The Senate voted 51-50 to table an amendment that would have denied financing to the agency to carry out a rule guaranteeing renewable fuels a 15 percent share of the lucrative fuel oxygenate market in 1995. That share rises to 30 percent in following years....

Yes Al, some of us remember.

Corn-based ethanol, which for years has been mixed in huge quantities into gasoline sold at U.S. pumps, is likely a much bigger contributor to global warming than straight gasoline, according to a study published Monday.

The study, published in the Proceedings of the National Academy of Sciences, contradicts previous research commissioned by the U.S. Department of Agriculture (USDA) showing ethanol and other biofuels to be relatively green.

President Joe Biden's administration is reviewing policies on biofuels as part of a broader effort to decarbonize the U.S. economy by 2050 to fight climate change.

“Corn ethanol is not a climate-friendly fuel,” said Dr. Tyler Lark, assistant scientist at University of Wisconsin-Madison Center for Sustainability and the Global Environment and lead author of the study.

The research, which was funded in part by the National Wildlife Federation and U.S. Department of Energy, found that ethanol is likely at least 24% more carbon-intensive than gasoline due to emissions resulting from land use changes to grow corn, along with processing and combustion.

Geoff Cooper, president and CEO of the Renewable Fuels Association, the ethanol trade lobby, called the study "completely fictional and erroneous," arguing the authors used "worst-case assumptions cherry-picked data."....

"One of the reasons I made that mistake is that I paid particular attention to the farmers in my home state of Tennessee, and I had a certain fondness for the farmers in the state of Iowa because I was about to run for president."...MORE
