The soy, corn, sunflower, rape seed (Canola) and oil palm plants all consume
CO2 as they are grown.
Using bio-diesel, because it's made from a plant that consumed CO2 while
being grown, has a Net Zero CO2 output. This is why it's better for global
warming.

E. Lowe mentioned:

The ability to use renewable  bio
fuels and thus contribute zero to global warming tips the balance.
Biofuels don't have to come from subsidized soybeans.

So I tossed in my tinke-tinke:

Seems to me the global war-ming is caused by excess greenhouse gases, CO2
being the most significant.  Diesel cycle engines produce CO2 as an exhaust
component in approximately the same quantity per stroke regardless of the
fuel source D1,D2, McDooDoo or Chik-fil-a or soybean oil.  I fail to
understand (my usual excuse) how using "organic" "free range" "home grown"
oil sources would significantly affect the CO2 fraction of the exhaust gas.
