Ozone layer - The ozone layer, or ozonosphere, is that part of the Earth's stratosphere which contains relatively high concentrations of ozone (O3). "Relatively high" means a few parts per million, much higher than the concentrations in the lower atmosphere but still small compared to the ...
Ozone depletion potential - The ozone depletion potential (ODP) of a chemical compound is the relative amount of degradation to the ozone layer it can cause, with trichlorofluoromethane (R-11) being fixed at an ODP of 1.0.
Montreal Protocol - The Montreal Protocol on Substances That Deplete the Ozone Layer is an international treaty designed to protect the ozone layer by phasing out the production of a number of substances believed to be responsible for ozone depletion. The treaty was opened for signature on September 16, 1987 and entered into force ...
Dichlorodifluoromethane - Dichlorodifluoromethane (R-12), usually sold under the brand name Freon-12, is a chlorofluorocarbon halomethane used as a refrigerant and aerosol spray propellant until its manufacture was discontinued in 1995, due to concerns about damage to the ozone layer. The ozone depletion potential of R-12 is 0.

It is suspected that a trend of global ozone depletion, which is caused by CFC emissions, ...
