Coalis acombustibleblack or brownish-blacksedimentary rock, formed asrock stratacalledcoal seams. Coal is mostlycarbonwith variable amounts of other elements; chieflyhydrogen,sulfur,oxygen, andnitrogen.Coal is formed when deadplant matterdecays intopeatand is converted into coal by the heat and pressure of deep burial over millions of years.Vast deposits of coal originate in formerwetlands—calledcoal forests—that covered much of the Earth's tropical land areas during the lateCarboniferous(Pennsylvanian) andPermiantimes.
Coal is primarily used as a fuel. While coal has been known and used for thousands of years, its usage was limited prior to theIndustrial Revolution. With the invention of the steam engine coal consumption increased. As of 2016, coal remains an important fuel as it supplied about a quarter of the world'sprimary energyand two-fifths ofelectricity.Someironandsteelmaking and other industrial processes burn coal.
The extraction and use of coal causes many premature deaths and much illness.The coal industrydamages the environment, including byclimate changeas it is the largestanthropogenicsource ofcarbon dioxide, 14gigatonnes(Gt) in 2016,which is 40% of the total fossil fuel emissionsand almost 25% of total globalgreenhouse gasemissions. As part of the worldwideenergy transitionmany countries have reduced or eliminated their use of coal power, and theUN Secretary Generalhas asked governments to stop building newcoal plantsby 2020.Coal use peakedin 2013but to meet theParis Agreementtarget of keepingglobal warmingto well below 2°C (3.6°F) coal use needs to halve from 2020 to 2030.
