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.
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.
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.
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.
no
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.
Yes. CFCs, or Chlorofluorocarbons, are banned in Australia. HCFCs, or hydrochlorofluorocarbons, which were a temporary replacement for CFCs, are also being phased out.
If CFC's are banned, all will be affected. It is due to the fact that they are harmful.
chlorofluorocarbons (CFCs)
CFCs have been 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.
We have to ban CFC's because of their adverse affects. They affect the ozone by depleting them.
CFCs are greenhouse gasses banned under the Montreal Protocol.

CFCs, Chlorofluorocarbons.
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.
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.
CFCs were banned because they were causing ozone depletion,allowing hazardous UV rays to penetrate earth's atmosphere.
