DOE & USDA study proves biodiesel massively  reduces dangerous emissions...
 
Haase Comments - In today's climate,  presenting a purely economic argument against a biofuel is a naive and one  dimensional point-of-view with all the noninvasive biofuel option. However, to  stop biofuel deforestation and further ecological destruction... U.N. needs to  establish global regulations on the market (like current logging)   Biodiesel, it's good stuff.(From autobloggreen.com) The U.S.  Department of Energy and the U.S. Department of Agriculture have published the  results of the Biodiesel Lifecycle Inventory Study which looked at energy  resources consumed and air, water and solid waste emissions generated by  petroleum diesel fuel and biodiesel. The intention of the three-and-a-half-year  study was to provide a comprehensive "cradle to grave" environmental comparison  of the two fuels in order to compare the total "lifecycle" costs and benefits of  each.
It was determined that biodiesel has a total fossil energy efficiency ratio (i.e., total fuel energy / total fossil energy used in production, manufacture, transportation and distribution) four times greater than that of petroleum diesel fuel making biodiesel far more efficient in its use of non-renewable fossil fuels.
Other key findings showed that in comparison to petroleum diesel, Biodiesel had:
