CFCs were banned because they were causing ozone depletion,allowing hazardous UV rays to penetrate earth's atmosphere.
What else can I help you with?
Why earlier CFC emmision were less?
Earlier CFC emissions were less because they were mostly released through industrial processes like refrigeration and aerosol production before regulations limited their use. As awareness of their harmful effects on the ozone layer grew, international agreements such as the Montreal Protocol were put in place to phase out CFC production and use. This has significantly reduced CFC emissions over time.
What is the international agreement to limit CFC production?
The international agreement to limit CFC production is the Montreal Protocol. This treaty was designed to phase out the production and consumption of ozone-depleting substances, including CFCs, in order to protect the Earth's ozone layer. The Montreal Protocol has been successful in reducing CFC levels in the atmosphere and has been hailed as an example of effective global cooperation.
What is CFC-11 and CFC-12?
CFC-11 and CFC-12 are chlorofluorocarbons, which are synthetic compounds that were once commonly used as refrigerants and propellants. These chemicals are now known to significantly deplete the ozone layer in the Earth's stratosphere, leading to the development of the Montreal Protocol to phase out their production and use.
What international treaty effectively banned global production of CFC?
The treaty is Montreal Protocol. It was signed in Montreal only.
What is the amount of CFC in the atmosphere in 2000?
In 2000, the amount of chlorofluorocarbons (CFCs) in the atmosphere was estimated to be around 2.7 parts per trillion. This was a significant decrease compared to levels in the late 20th century due to the implementation of the Montreal Protocol to phase out CFC production.
What year did cfc production reach its highest level?
the years of 1975 and 1987
What happened to CFC production after 1987 Why?
CFC production decreased significantly after 1987 when the Montreal Protocol was signed by countries to phase out the production of ozone-depleting substances like CFCs. This international agreement aimed to protect the ozone layer in the Earth's atmosphere, which was being depleted by the release of CFCs into the air.
Why did ozone holes happened?
They happened because of ozone depleting substances. CFC's are one of them.
Why does the ozone hole happen?
The ozone hole happened when CFC's introduced. It caused due to depleting property of CFC's.
What happened after the discovery of the ozone hole with respect to cfc's?
Nothing really!

Why is the ozone hole above Antarctica inspite of no production of CFC in that region?
It is mainly due to the impact of westerlies. Westerly winds carry the CFC's to the poles where they cause depletion.
What happened to ozone layer?
Ozone layer is getting depleted. It is due to CFC's used.
What action resulted from a 1987 meeting reducing the amount of Cfc's released by participating countries?
Montreal Protocol
What was the Production Budget for What Just Happened?
The Production Budget for What Just Happened was $27,000,000.
