Well it is more eco friendly then most other fuels Answer: It is always necessary to look at a fuel through it "life". This includes production, transportation, storage, use, loss and disposal.

Overall ethanol fuels have a smaller energy density. You have to use more of them to go as far. The emissions are generally stated in gm/km not gm/kg fuel. This confuses the issue Grain derived ethanol still has a significant environmental footprint from the chemicals, transportation and processing needed for its production. Diverting food to fuel is wrong at many levels. Waste biomass conversion to ethanol is better. Alcohol or gasohol fuels have some problems with the production of aldehydes and ketones in the tailpipe gases. In addition, spills of ethanol to water have a soluble portion that can significantly impact clean-up effectiveness.
