Well, you're starting off with less. * High-level ethanol blends reduce nitrogen oxide emissions by up to 20% * Ethanol's high oxygen content reduces carbon monoxide levels more than any other oxygenate: by 25-30%, according to the US EPA * Ethanol blends dramatically reduce emissions of hydrocarbons, a major contributor to the depletion of the ozone layer * Ethanol can reduce net carbon dioxide emissions by up to 100% on a full life-cycle basis * High-level ethanol blends can reduce emissions of Volatile Organic Compounds (VOCs) by 30% or more (VOCs are major sources of ground-level ozone formation) * As an octane enhancer, ethanol can cut emissions of cancer-causing benzene and butadiene by more than 50% * Sulphur dioxide and Particulate Matter (PM) emissions are significantly decreased with ethanol.
