carbon gives energy to the fuels, oil, gas, wood, corn ect. x lbs of carbon produces Y btu's (or Kwh) of energy. less carbon = less energy per gallon/lb/cubic feet ect ect
it takes Y amount of energy to do something. like many of our gas tractors take 4.5gal/hour of gas doing hard field work. it takes a certain amount of energy to plow an acre of ground. doesn't matter where that energy comes from. if burning ethanol figure on 6.2gal/hour instead of 4.5 or maybe 4 gal/hr in diesel (just examples based on btu/gal) your mileage may vary :)
if the fuel is able to be burned more efficiently (which seems to be renewable diesel claims) then i can see it having lower carbon output for work done.
using food to power our cars isn't a good idea. we will pay for it one way or another. higher $ at pump or higher $ at the grocer
in reality this whole thing is a scam. when they get a 3 day forecast right I might believe their 30 year 1C degree GLOBAL temperature rise let alone their 100 year predictions.

This story is about the day my Grandfather Brown (true name) decided along with my parents to purchase a new Ford tractor. It wasn't really new except to us. The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S
