Notes about data:
These data are from the United Nations Environmental Program (UNEP) Report: "Production and Consumption of Ozone Depleting Substances  1986 - 1998".

Information from the US EPA website:  
Chlorofluorocarbon (CFC): a compound 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-11, which constitute Group I . The ozone depletion potential (ODP) for each CFC is, respectively, 1, 1, 0.8, 1, and 0.6.

Variables:

year- year

odp_tons- ODP tons which is metric tons times ozone depletion potential
