Which countries stop destroying ozone layer?
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.
Which contries still use chlorofluorocarbon?
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.
What product releases cfcs?
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.
Are there hairsprays that still have CFCs in them?
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.
Why did many countries stop using DDT?
DDT is dangerous for the environmement.

What agreement was signed in 1988 by forty countries who were concerned about the ozone layer?
The Montreal Agreement is a successful international treaty to stop the production of CFCs (chlorofluorocarbons).

What is the consequence of an increase of CFCs - chlorofluorocarbons - in the atmosphere?
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).
What is the term for gases produced by aerosols and manufacturing that destroy the ozone layer?
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.
When will CFC stop to react with Ozone?
The world has agreed to stop manufacturing CFCs. If no other pollution damages the ozone layer it should have recovered by about 2050.
What is the term for gases produced by aerosols manufacturing that destroy the earth's ozone layer?

Why did many countries stop using DDT?
DDT is dangerous for the environmement.
Does refrigerator release CFC outside of cabinat while working?
I THINK there is a ban on CFC refrigerators in many countries already.
Do polystyrene containers play a part in the thinning of ozone layer?
At one time, polystyrene foam was blown using CFCs as stable gases for initially filling the little voids in the foam. The CFCs would later diffuse into the atmosphere. Polystyrene foams in most countries are not blown using CFCs as a blowing agent today.
Why is it important to phase out the use of chlorofluorocarbons?
Countries agreed at the Montreal Conference to ban the use of chlorofluorocarbons (CFCs). It was clear to everyone that CFCs were damaging the ozone layer and this could lead to severe damage to humans. This ban has been the most successful international intervention ever. No CFCs are now being released and scientists hope the ozone level will have self-repaired by 2060 (CFCs hang about in the atmosphere for up to 75 years!).
