Subbituminous coal is the predominant rank of coal produced west of the Mississippi River, accounting for 62 percent of the region's total coal output in 1992. Subbituminous coal in Wyoming's Powder River Basin, the principal source of this rank of coal, has an emission factor of pounds of carbon dioxide per million Btu.

Gas content in the Powder River Basin is much lower than in the San Juan Basin (Table ), but the large production of gas in the Powder River Basin suggests that low gas content is compensated by large coal volumes. This also suggests that the Powder River Basin may feature a significant contribution of free (, not adsorbed) gas in its coal.
