[GHG Network] Biodiesel Carbon Displacement Calculation

[Mark A. Delucchi]

Hi all,

I don't think GREET has tallow biodiesel. Also, GREET has by now well- 
known limitations in the area of biofuel LCA; see LCA research on my  
web site for details. I don't know about GHGenius (which was derived  
originally from my model).

If you are interested in the effect of biodiesel from tallow on  
climate, then the usual "first approximation" probably isn't right by  
a long shot!
