Yes, the production of ozone-depleting gases is regulated under a 1987 international agreement known as the montreal protocol on substances that deplete the ozone layer and its subsequent Amendments and Adjustments. The Protocol, now ratified by over 190 nations, establishes legally binding controls on the national production and consumption of ozone-depleting gases. Production and consumption of all principal halogen-containing gases by developed and developing nations will be significantly phased out before the middle of the 21st century.   _{Your Comment}
