Because of its high carbon content, coal emits more CO2 than any other fossil fuel when itâs burned. Itâs also the main source of fuel for electricity worldwide, and in the United States it accounts for 83 percent of greenhouse gas emissions in the electric power sector.
Coal is mostly carbon. During complete combustion, carbon is oxidised to carbon dioxide: carbon + oxygen â carbon dioxide. Carbon dioxide is a greenhouse gas greenhouse gases: the gases responsible for the global warming-carbon dioxide, methane, nitrous oxide and CFCs.Increasing concentrations of it in the atmosphere contribute to global warming. Hydrocarbon fuels contain carbon and hydrogen.oal is mostly carbon. During complete combustion, carbon is oxidised to carbon dioxide: carbon + oxygen â carbon dioxide.
