EPA Releases Comprehensive Study on Biodiesel Emissions

Dramatic Reductions in Particulate Matter, Unburned Hydrocarbons, and Carbon Monoxide

JEFFERSON CITY, Mo. – The Environmental Protection Agency (EPA) has released a new comprehensive technical report of biodiesel emissions data that shows biodiesel use can reduce emissions of particulate matter by 47 percent when compared to petroleum diesel in unmodified diesel engines. The report also verified a 67 percent reduction in unburned hydrocarbons and a 48 percent reduction in carbon monoxide with pure biodiesel (B100). While the technical report, which is a compilation of 39 separate scientific studies, is not an official rulemaking, the release of the report by EPA provides a government-validated reference for federal, state and local pollution strategies to reduce emissions that are harmful to human health and the environment.

EPA prepared the report because of increasing interest in biodiesel, a domestically produced alternative fuel that can be made from any fat or vegetable oil. Biodiesel works in any diesel engine with few or no modifications and has achieved a full national standard (ASTM D 6751). More than 250 vehicle fleets use B20, a mixture of 20 percent biodiesel with 80 percent petrodiesel, commercially nationwide. Lower level biodiesel blends, such as B2 or B5, are used in countless pieces of equipment from tractors to over the road semi trucks, and hundreds of fuel distributors are now carrying biodiesel blends nationally.

“This EPA evaluation provides independent confirmation of the emissions benefits of biodiesel, which is important for air planners and customers who are evaluating the switch to biodiesel, ” saidJoeJobe,executivedirectoroftheNationalBiodieselBoard(NBB). “Wearepleasedthat the EPA numbers are actually a little higher than our own analysis, and that they show benefits can be obtained at any biodiesel concentration in a mostly linear fashion, as we have been advising. We are planning to adopt the EPA analysis so NBB and EPA will be giving out the same set of numbers.”

During the last few years, biodiesel has enjoyed commercial success as one of the most thoroughly tested fuels in the country. “The fact that biodiesel is so well tested actually led to some uncertainty as to which set of emissions data was most accurate,” said Steve Howell, technical director for the National Biodiesel Board and chairman of the American Society of Testing and Materials (ASTM) Biodie sel Standards Taskforce.
