Okay I realize this is a really stupid question, but I haven't been in a chem class in about 5 years, so please cut me some slack.
But, if cars run on fat and produce a lot of pollution as a by product, is there a similar negative biproduct emitted when humans run on fat (ex. butter, coconut oil, etc) as opposed to clean burning carbs (sweet potatoes, lentils, sprouted grains, etc.)?

"Oil" (as in petroleum) is not "fat" (i.e. a 100% lipid). Petrol / gasoline is made up of over 100 chemicals, some of which are lipids. So, your premise is a bit off. ;-)
Humans "run on" carbohydrates, fats, proteins, organic acids, polyols, and ethanol. I'm probably missing something, but we don't directly "burn" anything else. I'm also using "scare quotes", since we don't actually "burn" these things like a combustion engine would burn gasoline. We also convert some macronutrients to other nutrients on an as-needed basis: proteins to simpler carbohydrates, for e.g.
There is nothing "cleaner" about "burning" fats versus carbohydrates or vice-versa. (Although, if you eat some fiber rich foods, those around you may not appreciate the generation of flatus!)
