Biodiesel is fully approved for use in the United States and it has been registered as a fuel and fuel additive with the EPA (Environmental Protection Agency). Neat biodiesel has been designated as an alternative fuel by the Department of Energy (DOE) and the US Department of Transportation (DOT). This fuel meets clean diesel standards established by CARB, the California Air Resources Board.

The increasing demand of this fuel is easily observed through the National Biodiesel Board statistics which reveals sales volume estimates for the US in the year 1999 of 500,000 gallons; in 2000, 2 million gallons were sold. 2001 increased the sales to 5 million gallons and it was the triple volume (15 million gallons) in the year 2002. Then after, the sales volume continues increasing on average good proportion, 20 million gallons in 2003, and 25 million gallons for 2004.

A lifecycle study realized in 1998, jointly sponsored by the US Department of Energy and the US Department of Agriculture, concluded biodiesel's closed carbon cycle reduces net CO² emissions by 78 percent in comparison to petroleum diesel. CO² is released into the atmosphere after biodiesel is burned but recycled by growing plants, which at the end are processed into fuel. Biodiesel emissions have decreased levels of polycyclic aromatic hydrocarbons and nitrated polycyclic aromatic hydrocarbons compounds, identified as potential cancer causing compounds. Biodiesel exhaust has a less harmful impact on human health than petroleum diesel fuel.

Biodiesel can be found anywhere in the United States, however if you need to locate the nearest station to you, The National Biodiesel Board (NBB) maintains a list of registered fuel marketer by calling them at 1-800-841-5849 or consulting their online list available at the NBB website, www.biodiesel.org.

It is expected biodiesel will be viewed by 2015, as an integral component of a national energy policy which increasingly relies on clean, domestic, renewable fuels.
