Curiously enough, chlorine radicals and volatile organic compounds from coal and wood combustion have the opposite effect in the lower atmosphere, where the interaction increases ozone production (due to reaction with various nitrogen oxides). This also generates the lung irritant PAN which is a component of brown smog:

> "The chlorine radical is a potent atmospheric oxidant, capable of perturbing tropospheric oxidative cycles normally controlled by the hydroxyl radical. Significantly faster reaction rates allow chlorine radicals to expedite oxidation of hydrocarbons, including methane, and in polluted environments, to enhance ozone production... Even when present at low levels, Cl radicals can have a profound impact on tropospheric oxidation and radical cycling. Cl chemistry can significantly impact levels of tropospheric ozone, a greenhouse gas that is also a precursor for the OH radical, destroying it in clean environments and enhancing its formation under polluted conditions."

Incidentally, Australia's massive wildfires of 2019-2020 produced about 700 million tons of CO2, which is only about 1/3 of Australia's annual fossil CO2 generation from coal (counting total production of Australian coal, of which only about 1/5th is burned in Australia itself, the rest being exported).

If you want to eliminate fossil fuel use, and aren't just posturing for political convenience, stopping production makes a lot more sense than stopping emissions at point-of-use.
