It takes about 25% more oil to make a gallon of diesel fuel than a gallon of gas. So, if you figure you pay ~15% premium... make some assumptions about light sweet crude oil (the commodity) as a $% of gross retail cost (i.e.; back out margin's, refining, tax, etc...). Bad news, since Diesel uses more crude, as crude $'s go up and become a larger % of gross retail cost, the delta between gas and diesel should theoretically increase. Personally, I believe, as the carbon market matures, we (diesel consumers) should be given a break since we produce comparatively less carbon (green house gas). Wouldn't it be great if we got a carbon credit at the pump to help offset the higher production cost (e.g.; refining and crude)...

Sorry, but no.
I'm not sure where you got that information from, but it smacks of the anti-diesel lobby, as that is the exact kind of crap they spew.
Crude oil is refined by heating in a column and waiting for the separation of layers. Hence why diesel is referred to as a "middle distillate" b/c it comes out from the middle of the column, heavier oil is below it, Kerosene is above it, gasoline is above that. As for the amounts... Not so much. Diesel is EASIER to refine than gasoline, and maintains more of the source hydrocarbon chains (and more volume by extension) than gasoline does.
Granted this explanation is extremely simplified, but it gets the general point across: As diesel is closer to the source material, it is easier to manufacture, and retains more volume b/c less needs to be removed to reach that final product.
I have seen postings extremely similar to yours in the last few days on several different alternative fuel or diesel forums. I would think there is a concerted effort to defame diesel engines just as they are regaining popularity and the future of this country might be one with less fuel usage... But then that would make me a conspiracy theorist.
It does make one wonder however... How far would the oil industry go? Taking back all the EV-1 cars and destroying them b/c they could put a big dent in oil... Defaming diesel for similar reasons... Constantly talking about "gas to liquid" and "gassification" of everything under the sun... Except that none of these products will be commercially available anytime soon... Defaming biodiesel from waste sources along with any other alternative fuel option as "unable to replace ALL of our needs, so let's not do it at all" kind of talk...
It certainly makes you think.
