Environmental Effects. Mining for oil shale can have damaging effects on the environment. When shale oil is combusted (heated), it releases carbon dioxide into the atmosphere. Carbon dioxide is a greenhouse gas; it absorbs and retains heat in Earth’s atmosphere, a process called the “ greenhouse effect.”Further, its success has come at the cost of environmental and health impacts.
