“the production of corn-based ethanol in the United States has failed to meet the policy’s own greenhouse gas emissions targets and negatively affected water quality, the area of land used for conservation, and other ecosystem processes” (From https://www.pnas.org/doi/10.1073/pnas.2101084119 https://www.pnas.org/doi/10.1073/pnas.2101084119) The study doesn’t even consider land use impact, food prices, etc. Ethanol seems to be a failure in all dimensions.
