Except for the fact that fossil fuel is used:

- To make fertilizer and pesticides to grow the grain
- To transport the fertilizer and pesticides to the farm
- To power the farm equipment that plants, maintains, and harvests the 
grain
- To transport the grain to the oil plant for processing
- To transport the oil to your processor, dealer, or home
- To deliver the processed fuel to your distributor (if applicable)

How much fossil fuel?  That I don't know.  

However, if you obtain used vegetable oil from local restaurants and 
reprocess it into fuel, one could argue that you're getting your fuel with 
no 
^additional^ use of fossil fuels (providing you haul it with your BD 
fueled 
vehicle).  You're also saving landfill space.

But even at that, and even though BD burns cleaner than regular diesel, 
that 
isn't saying much since Diesel is quite high in soot and NOx emssions.  
Even BD is never going to be as clean as an EV.  

The moral is, don't throw over your ET for a BD tractor!
