Many countries implemented regulations to phase out the production and use of chlorofluorocarbons (CFCs) in response to their harmful effects on the ozone layer. A key international agreement, the Montreal Protocol, was adopted in 1987, which set legally binding targets for reducing and eventually eliminating CFCs and other ozone-depleting substances. Countries committed to transitioning to safer alternatives and promoting technologies that do not harm the ozone layer, significantly reducing CFC emissions worldwide.
Many countries have ratified the Montreal Protocol, an international treaty aimed at protecting the ozone layer by phasing out the production of substances that deplete it, such as chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). Countries that adhere to the regulations outlined in the Montreal Protocol are actively working to stop destroying the ozone layer.
Many countries have phased out the use of chlorofluorocarbons (CFCs) due to their harmful effects on the ozone layer. Some developing countries may still use them in limited quantities for specific applications where alternatives are not readily available. Overall, the use of CFCs has decreased significantly worldwide in compliance with the Montreal Protocol.
Chlorofluorocarbons (CFCs) were commonly used in products such as aerosol sprays, refrigeration systems, air conditioning units, and foam-blowing agents. These substances were popular due to their effectiveness and stability; however, they were later found to contribute to ozone layer depletion. As a result, many countries have phased out the use of CFCs in favor of more environmentally friendly alternatives.
As of October 2023, the use of chlorofluorocarbons (CFCs) is largely banned under the Montreal Protocol, with most countries having phased them out. However, some developing countries may still have limited use or stockpiles of CFCs due to economic constraints or lack of access to alternatives. The use of CFCs is primarily restricted to certain applications, such as in some medical devices or older refrigeration systems, but overall, their use is minimal and declining globally.
Probably not. There may be some small companies in developing countries still using CFCs but all major countries have phased them out by the end of last century. Hairsprays have other chemicals which may not be good for the atmosphere either. We may have to wait and see.

The Montreal Agreement is a successful international treaty to stop the production of CFCs (chlorofluorocarbons).

The consequence was the destruction of the ozone layer. However, the Montreal Protocol got all countries in the world to agree to stop the production of CFCs (chlorofluorocarbons). This happened, and the ozone layer is actually repairing itself and should be fully recovered by 2050 (unless we emit some other polluting chemical in the interim).
chlorofluorocarbons (CFCs) "ozone depleting substances" are more generic, since other chlorine- and bromine-containing molecules, which are produced by Man, have been found "up there" too. Note that CFCs are not "produced by aerosols", but were intentionally manufactured for the purposes of refrigerant and propellant. Not too many countries are still making / using CFCs.

The world has agreed to stop manufacturing CFCs. If no other pollution damages the ozone layer it should have recovered by about 2050.

I THINK there is a ban on CFC refrigerators in many countries already.
DDT is dangerous for the environmement.
