How does chimney reduce air pollution?

Do chimneys contribute to climate change?
Besides increasing or decreasing the levels of ozone in the upper atmosphere, some of the chemicals also contribute directly to the greenhouse effect. For example, added water vapor pumped into the upper atmosphere from the chimney increases the amount of energy trapped there, in turn heating the planet further.
