5. It depends on how the ethanol is produced

In this case they’re using renewable electricity, carbon dioxide CO₂ and water H₂O to produce ethanol CH₃CH₂OH. When it is burned, it will produce CO₂ and water vapor H₂O. It is essentially “carbon neutral."

Ethanol can also be used in fuel cells.

New Ethanol Fuel Cell Technology Rivals Fossil Fuels and Electric Car Batteries
Ethanol fuel cells, in which alcohol can be poured directly in as fuel, offer cleaner emissions than fossil fuels and no charging times compared to electric vehicle batteries.

University of Central Florida researchers have achieved new record-setting power density for ethanol fuel cells, helping advance the technology as a competitor to fossil fuels and electric car batteries.

Ethanol fuel cells offer cleaner emissions than fossil fuels and no charging times compared to electric vehicle batteries.

In recent studies published in the journals Nature Communications and Joule, UCF NanoScience Technology Center Associate Professor Yang Yang and his team developed new catalysts to make direct ethanol fuel cells last longer and boost their power density to a record level.
