Creosote is a form of ground cover, colloquially know as "scrub-brush". Like many plants, it has active organic chemistry and was one used for medicinal and industrial uses. While creosote has been linked to naturally occuring compounds that "makes smog worse", to equate "chopping down trees" to managing "emissions" is pretty loose logic. The relationship of man-made pollutants to smog is that the latter are not uniformly benign; local topography weather, and fora combine industrial air-borne pollution more problematic in some areas (LA) than others (eg SF). In theory, if we paved over LA we could reduce the dust and the creosote and maybe reduce "smog", but again this is not environmentalism, but rather geo-engineering.
