CFC's (chlorofluorocarbons) are refrigerants ("Freons"). It was discovered some years ago that their eventual leakage into the atmosphere was causing a destruction of a natural layer of ozone in the earths upper atmosphere, which acts as an important barrier to excessive UV radiation.
CFC's were banned about 20-25 years ago, and replaced with other, non-harmful fluorocarbons.
It has had an effect - a recent report in Time magazine stated that the "hole" in the ozone layer is almost repaired due to the elimination of CFC's.
