Biodiesel is a domestically produced, renewable fuel that can be manufactured from vegetable oils, animal fats, or recycled restaurant grease for use in diesel vehicles. Biodiesel’s physical properties are similar to those of petroleum diesel, but it is a cleaner-burning alternative. Using biodiesel in place of petroleum diesel, especially in older vehicles, can reduce emissions.


Biofuels and Biomass Interest Groups (includes Ethanol & Biodiesel)




  • Biodiesel can be produced in the U.S. and used in conventional diesel engines directly substituting for or extending supplies of traditional petroleum diesel
  • Engines manufactured in 2010 and later have to meet the same emissions standards
  • whether running on biodiesel diesel or even natural gas
  • Using biodiesel reduces greenhouse gas emissions because carbon dioxide released from biodiesel combustion is offset by the carbon dioxide sequestered while growing the soybeans or other feedstock
  • Biodiesel improves fuel lubricity and raises the cetane number of the fuel
  • Biodiesel is nontoxic
  • It causes far less damage than petroleum diesel if spilled or released to the environment
  • It is safer than petroleum diesel because it is less combustible
  • Biodiesel is safe to handle and transport
