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.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
