The CFC problem is largely under control, thanks to the Montreal Protocol on Substances that Deplete the Ozone Layer - an unprecedented international agreement negotiated under the auspices of UNEP. The Protocol established a new way of addressing environmental problems: the original agreement was negotiated on the basis of the ozone depletion theory - which predicts that human-made CFCs would deplete the stratospheric ozone layer.
