Fossil Energy Study Guide: Coal
Also, coal, like all fossil fuels, is formed out of carbon. All living things—even people—are made up of carbon. But when coal burns, its carbon combines with oxygen in the air and forms carbon dioxide. Carbon dioxide (CO 2) is a colorless, odorless gas, but in the atmosphere, it is one of several gases that can trap the earth's heat.

coal - Problems associated with the use of coal | Britannica
Pollution from coal utilization. Coal utilization is associated with various forms of air pollution.During the incomplete burning or conversion of coal, many compounds are produced, some of which are carcinogenic.The burning of coal also produces sulfur and nitrogen oxides that react with atmospheric moisture to produce sulfuric and nitric acids—so-called acid rain.
