There are several different types of air pollution that arise as a result of oil sands bitumen extraction. In addition to the greenhouse gases released by the bitumen extraction process in the oil sands - primarily CO 2 (see climate impacts of oil sands for more information) - other pollutants are released during oil sands mining operations.. As is the case with the development of other fossil
