Anticipated future limitations on production and consumption of the fully halogenated CFCs and halons covered by the Montreal Protocol on Substances that Deplete the Ozone Layer (hereafter referred to as Protocol compounds) are expected to prompt substitution of these compounds with alternative, less ozone-depleting chemicals wherever it is cost effective and technically feasible to do so. Indeed, some alternative chemicals are already available and may find expanded use almost immediately. Examples of alternative chemicals in this category include hydrocarbons, non-fully halogenated CFCs (HCFCs), other chlorinated organics, and blends of CFCs with other compounds. Other possible alternative chemicals are not yet commercially available but are undergoing development in anticipation of demand (e.g., HCFC-123, HCFC-141b, and HFC-134a). EPA's Air and Energy Engineering Research Laboratory is performing a preliminary evaluation of additional novel halogenated compounds as possible long-term substitutes for currently used CFCs and halons. In the nearer-term, however, alternatives already available or closer to commercialization may find substantially increased usage. In this paper, the authors explore the applications in which these alternative chemicals may find utilization and project future use of such chemicals both in the U.S. and globally. Implications of future emissions of these alternative chemicals with regard to stratospheric and ground-level ozone are also discussed. Special attention is given to increased usage of alternative chemicals possessing some, though relatively low, potentials for destroying stratospheric ozone.
