Yes, fluorocarbons are still very stable, and capable of being substituted for the less expensive ozone-depleting compounds. CFCs were created because they did not promote burning, and they were not terribly expensive. So in order to avoid them, we have to mine and produce more fluorine to make these other compounds.
