Quizplus · Accepted Answer

Chlorofluorocarbons (CFCs) are greenhouse gases that were widely used as refrigerants and solvents, particularly in the manufacture of foam. However, their use has been largely phased out since they are also known to cause depletion of the ozone layer. Carbon dioxide and methane are also greenhouse gases, but are not commonly used as refrigerants or solvents. Water vapor is not considered a greenhouse gas because its concentration in the atmosphere is largely controlled by temperature rather than human activity.
