BENEFITS OF BIODIESEL
Environmental Benefits
In 2000, biodiesel became the only alternative fuel in the country to have successfully
completed the EPA-required Tier I and Tier II health effects testing under the Clean Air
Act. These independent tests conclusively demonstrated biodiesel’s significant
reduction of virtually all regulated emissions, and showed biodiesel does not pose a
threat to human health.
Biodiesel contains no sulfur or aromatics, and use of biodiesel in a conventional diesel
engine results in substantial reduction of unburned hydrocarbons, carbon monoxide
and particulate matter. A U.S. Department of Energy study showed that the production
and use of biodiesel, compared to petroleum diesel, resulted in a 78.5% reduction in
carbon dioxide emissions. Moreover, biodiesel has a positive energy balance. For
every unit of energy needed to produce a gallon of biodiesel, 3.24 units of energy are
gained.
Energy Security Benefits
With agricultural commodity prices approaching record lows, and petroleum prices
approaching record highs, it is clear that more can be done to utilize domestic
surpluses of vegetable oils while enhancing our energy security. Because biodiesel can
be manufactured using existing industrial production capacity, and used with
conventional equipment, it provides substantial opportunity for immediately addressing
our energy security issues.
If the true cost of using foreign oil were imposed on the price of imported fuel,
renewable fuels, such as biodiesel, probably would be the most viable option. For
instance, in 1996, it was estimated that the military costs of securing foreign oil was $57
billion annually. Foreign tax credits accounted for another estimated $4 billion annually
and environmental costs were estimated at $45 per barrel. For every billion dollars
spent on foreign oil, America lost 10,000 – 25,000 jobs.
Economic Benefits
Increased utilization of renewable biofuels results in significant microeconomic benefits
to both the urban and rural sectors, and the balance of trade. A study completed in
2001 by the U.S. Department of Agriculture found that an average annual increase of
the equivalent of 200 million gallons of soy-based biodiesel demand would boost total
crop cash receipts by $5.2 billion cumulatively by 2010, resulting in an average net farm
income increase of $300 million per year. The price for a bushel of soybeans would
increase by an average of 17 cents annually during the ten-year period.
In addition to being a domestically produced, renewable alternative fuel for diesel
engines, biodiesel has positive performance attributes such as increased cetane, high
fuel lubricity, and high oxygen content, which may make it a preferred blending stock
with future ultra-clean diesel.
Quality Benefits
Biodiesel is registered as a fuel and fuel additive with the EPA and meets clean diesel
standards established by the California Air Resources Board (CARB). B100 (100 percent
biodiesel) has been designated as an alternative fuel by the U.S. Department of Energy
and the U.S. Department of Transportation. Moreover, in December 2001, the American
Society of Testing and Materials (ASTM) approved a specification (D6751) for biodiesel
fuel. This development was crucial in standardizing fuel quality for biodiesel in the U.S.
market.
The National Biodiesel Board, the trade association for the biodiesel industry, has
formed the National Biodiesel Accreditation Commission (NBAC) to audit fuel producers
and marketers in order to enforce fuel quality standards in the US. NBAC issues a
‘Certified Biodiesel Marketer’ seal of approval for biodiesel marketers that have met all
requirements of fuel accreditation audits. This seal of approval will provide added
assurance to customers, as well as engine manufacturers, that the biodiesel marketed
by these companies meets the ASTM standards for biodiesel and that the fuel supplier
will stand behind its products.
EPAct Benefits
Effective November 1998, Congress approved the use of biodiesel as an Energy Policy
Act (EPAct) compliance strategy. The legislation allows EPAct-covered fleets (federal,
state and public utility fleets) to meet their alternative fuel vehicle purchase
requirements simply by buying 450 gallons of pure biodiesel and burning it in new or
existing diesel vehicles in at least a 20% blend with diesel fuel. The Congressional
Budget Office and the U.S. Department of Agriculture have confirmed that the
biodiesel option is the least-cost alternative fuel option for meeting the Federal
government’s EPAct compliance requirements. Because it works with existing diesel
engines, biodiesel offers an immediate and seamless way to transition existing diesel
vehicles into a cleaner burning fleet.
