A new study from the U.S. Department of Agriculture says corn-based ethanol emits less greenhouse gas than gasoline. As Harvest Public Media’s Grant Gerlock explains, it’s a hot-button debate.
The report says corn-based ethanol reduces greenhouse gas emissions by 43 percent. And with more no-till farming, more cover crops and better fertilizer management, emissions could decline further.
That’s good news for Midwest farmers and ethanol fans. But disputed by many environmental groups and the oil industry.
