How was CFC banned?
In 1976, under the Toxic Substances Control Act, the EPA banned commercial manufacturing and use of CFCs and aerosol propellants. This was later superseded by broader regulation by the EPA under the Clean Air Act to address stratospheric ozone depletion.
What was the name of the agreement that banned CFCs?
The Montreal Protocol
The Montreal Protocol is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for ozone depletion. It was agreed on 16 September 1987, and entered into force on 1 January 1989.
Are ozone-depleting substances banned?
See ozone depleting substance. (HCFCs). CFCs are Class I ODS, while HCFCs are Class II ODS. EPA regulations ban these products from sale and distribution in interstate commerce in the United States.
How many countries have banned CFCs?
197 countries
Today, the use of CFCs is outlawed by 197 countries around the world and scientists concur that the ozone layer is slowly recovering as a result.
Why is it called Montreal Protocol?

When did CFC get banned?
1987
A 1987 worldwide ban on ozone-depleting chemicals known as chlorofluorocarbons (CFCs) averted a dangerous rise in the level of ultraviolet radiation (UV) reaching the Earth’s surface.
Is the Montreal Protocol still in effect?
The United States ratified the Montreal Protocol in 1988 and has joined four subsequent amendments. The United States has been a leader within the Protocol throughout its existence, and has taken strong domestic action to phase out the production and consumption of ODS such as chlorofluorocarbons (CFCs) and halons.
