Engineering Explained examines new research suggesting corn ethanol in US gasoline may emit as much or more carbon than gasoline. It covers the Renewable Fuel Standard and why ethanol was assumed to be a green fuel.
Cited as an accessible summary of evidence that corn ethanol is no better than gasoline for emissions.

This paper shows how much more efficient switchgrass is at producing ethanol than corn. This video is an interesting look at this whole issue:(Engineering Explained - America Was Wrong About Ethanol) this video Especially his summary, where corn creates 20 percent less GHG than gasoline and ''breaks even'' after 28 years, while switchgrass creates 94% less GHG and breaks even in it's first year.

Supports your point with numbers: this video tl;dr: Corn-based ethanol is at best as bad a carbon emitter as gasoline, and it's most likely worse.
Wait, so your solution to massive economic harm caused by government regulations, and money printing is to increase government regulations and print even more money... That's a bold strategy, Cotton. Let's see if it pays off for them last time government tried to solve climate change we got 10% corn based ethanol gas which current research indicates has made things WORSE not better.[1] [1] this video
