One might consider also that the particulates in question are not some neutral fuzzy dust. When the fire's not going right, a large percentage of those particulates are "POM" polycyclic organic matter- powerful carcinogens. Not just a bit more fly axh. A bit more of a problem than some CO2.
Question is, as Fred points out, what can you do with people who focus purely on their own needs, and won't see to preparing quality fuelwood, nor see to burning it cleanly. The one strong point of liquid & gaseous fossil fuel burners is that once properly adjusted, they'll likely burn cleanly for an extended period. Yeah, don't press your luck with oil. At least nat. gas generates proportionately less CO2 than oil or coal.
How to enforce "Don't poison your neighbor" on people who just don't see a problem? Or care.
