Feb 14 (Reuters) - 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."
Under the U.S. Renewable Fuel Standard (RFS), a law enacted in 2005, the nation's oil refiners are required to mix some 15 billion gallons of corn-based ethanol into the nation's gasoline annually. The policy was intended to reduce emissions, support farmers, and cut U.S. dependence on energy imports.
As a result of the mandate, corn cultivation grew 8.7% and expanded into 6.9 million additional acres of land between 2008 and 2016, the study found. That led to widespread changes in land use, including the tilling of cropland that would otherwise have been retired or enrolled in conservation programs and the planting of existing cropland with more corn, the study found.
Tilling fields releases carbon stored in soil, while other farming activities, like applying nitrogen fertilizers, also produce emissions.
A 2019 study https://www.tandfonline.com/doi/full/10.1080/17597269.2018.1546488 from the USDA, which has been broadly cited by the biofuel industry, found that ethanol’s carbon intensity was 39% lower than gasoline, in part because of carbon sequestration associated with planting new cropland.
But that research underestimated the emissions impact of land conversion, Lark said.
USDA did not respond to a request for comment.
The U.S. Environmental Protection Agency, which administers the nation's biofuel policy, is considering changes to the program. Under the RFS, Congress set blending requirements through 2022, but not beyond, giving the EPA authority to impose reforms. EPA plans Explainer: What is at stake for the U.S. biofuel blending law in 2022 and beyond to propose 2023 requirements in May. (Reporting by Leah Douglas; Editing by David Gregorio)

Well.... when it says what you want others to go by.

Senator Grassley and other powerful farm state members of Congress. Any questions?

Hey, just trust the science!

just be sure to mask up when filling up and you'll be ok !

Got to wonder why we just dont visit some of these threads to solve all the worlds problems with so many geniuses in one spot,,, know more about this type of thing than most other people do.

It's just like a welfare program, it don't get turned off. It only grows, look at the worthless jobs.

Why are you buying $5 a quart fuel for your small engines? :confused2:

When you have a crew out building fences that you bid, do you want them fooling with a chain saw that wont run, or do you want them working?

Penny wise and Pound Foolish??!

Last year we bought a harbor freight post hole digger and they had a can of fuel there with the diggers and we bought that and that is all we use since that's our last two cycle on the place. Should have took the time to find electric one but I don't think Cobalt makes them and that's what all our large batteries are.

I believe he is thinking just buy $4 a gallon E0 (2021 price) or $3 a gallon E10 and treat it with a good fuel additive and you will have no fuel related problems for a lot less expense. That's what I have done for 20+ years.

I have the formula. Used to send a five gallon can on each truck once a week. So I made up 50 gallons of it once a week. They used a 5 each day per crew. I didn't have any more two stroke problems.
