One of the things all the automakers track is the efficacy and cost for different technologies. They maintained a ranked order of $/change in mpg for each technology and had to make a business case for using one technology over the other based on those calculations, but also considering mass, ability to package it in the vehicle and measure of any detrimental impact the tech would have on fuel economy or performance. Having seen their job I made it a point to NEVER put myself in a position of being in that staff area.

You sure do! The diesel industry was forced by government mandates to add fuel after combustion to OTR Trucks which cost 1MPG on a vehicle that gets maybe 8MPG ITFP. If CO2 is a pollutant, how is adding 13% more a solution when at the time this was implemented, we already reduced diesel "pollutants" 90%?
I'd say its not a problem.
