Consumption of Ozone-Depleting Substances - CFCs (1990-2016)

Consumption of Ozone-Depleting CFCs is the sum of the consumption of the weighted tons of the individual substances in the group—metric tons of the individual substance (defined in the Montreal Protocol on Substances That Deplete the Ozone Layer) multiplied by its ozone-depleting potential. Ozone-depleting substances are any substance containing chlorine or bromine that destroys the stratospheric ozone layer. The stratospheric ozone absorbs most of the biologically damaging ultraviolet radiation. The consumption of CFCs is the national production plus imports, minus exports, minus destroyed quantities, minus feedstock uses of individual CFCs. National annual consumption of CFCs is the sum of the weighted tons (consumption in metric tons multiplied by the estimated ozone-depleting potential) of the individual CFCs.
