Study Shows Biodiesel Reduces CO2 Emissions

John Davis

Just in case you need more evidence of the clean-burning nature of biodiesel, a new study once again confirms the fuel’s green nature.

A six-month demonstration by California-based fleet States Logistics’ saw carbon dioxide reduction of 72.9 tons compared to straight petroleum diesel. This National Biodisel Board press release says the company will be able to use the information to market to customers, and eventually, may use it to sell carbon offsets on the voluntary markets:

We all benefit from having this information available to show the efforts being made to reduce carbon footprint throughout the supply chain.”

States Logistics ran seven trucks: four on soy-based B5 (5% biodiesel and 95% petroleum diesel) and three on B99 (99% biodiesel and 1% petroleum diesel). The B99 trucks (three-axle International model 8600) ran 48,198 miles and consumed 8,770 gallons over the six month period. The equivalent straight petroleum diesel output would have been 89.9 tons, but with B99, the output was 19.8 tons for a savings of 70.1 tons. The B5 fleet (two-axle flat bed) traveled 61,433 miles and consumed 7,090 gallons of B5. Equivalent petroleum CO2 output would have been 71.4, with B5 the output was reduced to 68.6 for 2.8 tons of CO2 reduction. In addition to CO2 reduction, an estimated 119 pounds of particulate matter were eliminated from the exhaust during the six month period. Carbon monoxide (CO) was reduced by over 500 pounds, hydrocarbons (HC) by over 50 pounds, and sulfur dioxide (SO2) by close to 40 pounds.

The NBB released the results of the test during the recent Mid America Trucking Show (MATS)… the largest U.S. based trucking show, attracting nearly 60,000 truckers to Louisville, Ky. every year.

The organization also used the event to release the results of an online survey of owner-operators, independent and company drivers. NBB found: only 8 percent were not familiar with biodiesel; 75.8 percent have a positive impression of biodiesel; 57 percent have at least tried biodiesel and 94 percent would use biodiesel in the future; supporting American farmers tops the list of reasons for using biodiesel with 59 percent choosing this and 40 percent choosing energy independence.
