Frequently Asked Questions

  • What are CFC's?

    Chlorofluorocarbons (CFCs): compounds consisting of chlorine, fluorine, and carbon CFCs are very stable in the troposphere. They are broken down by strong ultraviolet light in the stratosphere and release chlorine atoms that then deplete the ozone layer. CFCs are commonly used as refrigerants, solvents, and foam blowing agents. The most common CFCs are CFC-11, CFC-12, CFC-113, CFC-114, and CFC-115.
