The Montreal protocol bans CFC's from modern countries and was signed on Sept. 16, 1987. Is was still being made and used as of this year in some countries.

How can chlorofluorocarbons be reduced?
The manufacture of chlorofluorocarbons (CFCs) for industrial use has been banned. When old refrigerators and airconditioning units are scrapped, the CFCs they contain should be trapped for reuse or destruction.
When and where were CFCs banned?
In Montreal in Canada in 1987 nations around the world agreed to stop producing CFCs. This agreement, probably the most successful international agreement ever, is called the Montreal Protocol. Because of this the ozone layer is not longer being damaged, and scientists hope that it will have repaired itself by 2060.
Why are CFCs banned as refrigerator coolants but are still allowed in aerosol cans?
Chlorofluorocarbons (CFCs) were once used as propellants in aerosol cans, but since the Montreal Protocol was agreed to in 1989, they have been replaced in nearly every country. This is because of the negative effects CFCs have on Earth's ozone layer. Aerosols are now propelled by mixtures of volatile hydrocarbons, typically propane, n-butane and isobutane. Food sprays use nitrous oxide and carbon dioxide.
Is there a tree which can absorb CFCs?
no
Are all CFCs greenhouse gasses?
Yes, even though they are primarily harmful because of their effect on ozone depletion. CFCs have both effects. The two effects are different. The ozone depletion is worse.
When were Chlorofluorocarbons banned in Australia?
Yes. CFCs, or Chlorofluorocarbons, are banned in Australia. HCFCs, or hydrochlorofluorocarbons, which were a temporary replacement for CFCs, are also being phased out.
If cfcs are banned who will be affected?
If CFC's are banned, all will be affected. It is due to the fact that they are harmful.
What was the ingredient in aerosol cans that banned them from use?
chlorofluorocarbons (CFCs)
What has the world done to help reduce ozone depletion?
CFCs have been banned.
What can companies that now produce CFCs do to replace money lost when CFCs are banned?
Make something else BUT this time check that the products they are making are not harmful. They aught also to pay towards the environmental harm that CFCs have caused.
Why we as a planet banned cfcs?
We have to ban CFC's because of their adverse affects. They affect the ozone by depleting them.
Why are CFC fridges not used anymore?
CFCs are greenhouse gasses banned under the Montreal Protocol.
How can chlorofluorocarbons be reduced?
The manufacture of chlorofluorocarbons (CFCs) for industrial use has been banned. When old refrigerators and airconditioning units are scrapped, the CFCs they contain should be trapped for reuse or destruction.
Which chemical has been banned in most of the world because of its role in destroying the ozone layer?
CFCs, Chlorofluorocarbons.
Where are CFCs?
There are no CFCs as they where banned because they react with the ozone layer O3 but they where mostly used in Australia which is why there is an opening in the ozone layer.CFCs are released when we use aerosol sprays, refridgerators and air conditioning units.
Are humans responsible for the depletion of the ozone layer?
Yes. People developed chemicals such as CFCs (Chlorofluorocarbons) for use in refrigerators and as a propellant gas in aerosols. These CFCs rose high into the atmosphere and caused damage to the ozone layer. the use of CFCs has since been banned and the ozone layer is slowly recovering. Hopefully.
What happened to CFC production after 1987?
CFCs were banned because they were causing ozone depletion,allowing hazardous UV rays to penetrate earth's atmosphere.
