I think you are confusing CO, CXXX, and a bunch of other products locally
refered to as smog, a result of photochemical conversions on partly
pyrolized hydrocarbon chains, with CO2 pollution, which is an interesting
global issue. Smog is a serious killing problem now. If we cracked coal to
H2 as a fuel rather than making an oil, this would help to solve the smog
problem, as long, of course, as we did something to control emissions from
the coal plant.

? Only one of 5 major topics here deals with CO2. Smog, oil supply limits
cost/limits, manufactured fuels in general are also major issues, and a lot
more direct in their impact than CO2.

Sure. But it is a good thing to remember that we are now using that methane
to sweeten the oil, so some significant amount of this fuel is producing
hydrogen, with whatever loss involved, and that hydrogen is being used to
fuel cars, albiet rather indirectly.
