Some of the main pollutants that are harmful to the stratosphere are called chlorofluorocarbons (CFCs).

The cooling gases - called chlorofluorocarbons, or CFC's - were therefore released into the air.

All types of air-conditioners and refrigerators use the ozone-depleting chemicals called chlorofluorocarbons, or CFC-12.

The products being phased out use chemicals called chlorofluorocarbons, or CFC's, to propel a mist of medicine.

A family of chemicals called chlorofluorocarbons, or CFC's, is generally regarded as the culprit.

In the 1970s it was discovered that man-made chemicals called chlorofluorocarbons (CFCs) were destroying the ozone in the ozone layer.

The molecules in question are called chlorofluorocarbons (CFCs).

The primary cause of the ozone hole is human-produced compounds called chlorofluorocarbons, or CFCs, which release ozone-destroying chlorine and bromine into the atmosphere.

Meant to phase out production of chemicals called chlorofluorocarbons that were believed responsible for ozone depletion, it is considered one of the most successful international agreements ever.

The compounds that contain only chlorine, fluorine, and carbon are called chlorofluorocarbons, usually abbreviated as CFCs.
