Success Story: CFC Production Has Fallen Sharply
Notes:
Annual Production of CFCs, 1986-95
Since 1987, global consumption of ozone-destroying substances such as chlorofluorocarbons (CFCs) has dropped more than 70 percent. For more information see http://www.wri.org/trends/ozone1.html.

Note: Ozone-depleting potential (ODP) tons is a measure by which ozone-depleting substances are weighted according to their ability to destroy ozone.
