Global Perspective on the Use of Low Quality Coals
Around half of the world's estimated recoverable coal reserves comprise low value coals, predominantly lignites, subbituminous coals, and high-ash bituminous coals. By rank (on a tonnage basis) anthracite and bituminous coals account for 51% of the world's reserves, subbituminous coal 32%, and lignite 18%.
