Re: That claim is "will" and then "is", and then it is all "we, we, we," meaning the pigs at the ethanol trough, so much for "spin"....?

"Is" cleaner? Or, "will be" cleaner, because of these "coming" changes in the manufacture of ethanol? Which is it? Or is it just some spin for the "true believers", coming out of both sides of his mouth?
"It is now 2018 and new data, scientific studies, technical reports, and other information allow us to examine the emissions pathway corn-ethanol has actually followed since 2010. Using this information, we assess corn ethanol's current GHG profile at 39–43% lower than gasoline."
This couldn't possibly just be the latest "spin" from an ethanol industry flack?
The oil industry has had such a proven track record on studies all things climate.
Give me an effin break!
"Not so fast? Really?" Yes really. You're subscribing to a 10 year old train of thought. The studies on the realities of ethanol are just starting to catch up to the hype.
Will they be reducing the greenhouse gas "footprint" of the ethanol "manufacturing process", or is there an actual breakdown, on how much "shipping" ethanol via rail and truck, using diesel, will add to the total carbon footprint?
"CO2 emissions from combusting gasoline and diesel fuels occur in transporting corn from farm to refinery, ethanol from refinery to retail station, and co-products from refinery to end users. While this category accounts for 5–6% of ethanol’s GHG profile, transportation vehicles and systems have become more fuel and GHG efficient since 2010"
"From GREET 2009, corn was assumed to move 10 miles by truck from the farm to a central collection point (i.e. the stack) and 40 miles by truck to the refinery. An Oak Ridge National Laboratory (ORNL) study provided projected 2022 fuel transportation modes and distances for ethanol from refinery to the blending terminal [37 Oak Ridge National Laboratory. Analysis of Fuel Ethanol Transportation Activity and Potential Distribution Constraints.
2009. DOI: 10.3141/2168-16. For co-products, the EPA obtained data from the USDA on modes and distances for transporting DGS from refineries to final users [1 U.S. Environmental; Protection Agency (EPA). 2010. Renewable Fuel Standard Program Regulatory Impact Analysis. EPA-420-r-10-006. February 2010. For each mode of transportation and associated distance traveled, GREET default assumptions and EFs were used."
"The RIA projected 2022 emissions for the fuel and feedstock transport category at 4265 g CO2e/MMBtu."
"Our method is similar to that of the RIA but incorporates updated assumptions, transportation mode and distance traveled data, and EFs from GREET 2015. Relative to GREET 2009, GREET 2015 includes: (1) new LCA EFs for five types of diesel and gasoline freight vehicles; (2) new transportation mode and distance traveled data for ethanol moving from refinery to blending terminal and from blending terminal to retail station; and (3) new life-cycle freight EFs for rail, barge, and truck"
I am with my old pal Barry. Who pointed this problem out many years ago when analyzing the transport costs. And, came to the conclusion, that it would be better for the environment and air quality, if we drank all of that ethanol, instead of burning it in our cars. Because, of all of the fuel we'd save, and the lower emissions and cleaner air that would result, since we would all be too drunk to drive.....
Barry sounds like a smart guy. For myself, growing up around subsidized land, I found it very disturbing how the government subsidized farmers to not use their land but instead let it sit idle, all the while farmers were being subsidized. Fuel, alcohol, it doesn't matter, both are a major step up.
