• Ethanol blends are likely to reduce carbon monoxide emissions in vehicles by between 10% - 30%, depending upon the combustion technology. (U.S. EPA)
  
  
• The American Lung Association of Metropolitan Chicago credits ethanol-blended fuel with reducing smog-forming emissions by 25% since 1990.
  
  
• The use of 10% ethanol blends reduces greenhouse gas emissions by 12-19% compared to conventional gasoline. (Argonne National Lab)
  
  
• In 2004, ethanol use in the U.S. reduced CO2-equivalent greenhouse gas emissions by approximately 7 million tons, equal to removing the emissions of more than 1 million cars from the road. (Argonne National Lab)
  
  
• Research shows a 35-46% reduction in greenhouse gas emissions and a 50-60% reduction in fossil energy use due to the use of ethanol as a motor fuel. (Argonne National Lab)
  
  
• Ethanol contains 35% oxygen, making it burn more cleanly and completely than gasoline.
  
  
• E85 has the highest oxygen content of any fuel available, making it burn even more cleanly and even more completely than any other fuel.
  
  
• E85 contains 80% fewer gum-forming compounds than gasoline.
  
  
• Ethanol is highly biodegradable, making it safer for the environment.
