What international treaty effectively banned global production of CFC?
The treaty is Montreal Protocol. It was signed in Montreal only.
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 cause the ozone hole to form change scientific knowleg?
Ozone hole allowed to make many important decision. Main was to limit the production of CFC's.
What action has the international community taken to help prevent further damage to the ozone layer?
The international community came together to create the Montreal Protocol, an agreement to phase out the production and consumption of ozone-depleting substances. This protocol has been successful in reducing the damage to the ozone layer. Countries also regularly report on their progress and compliance with the protocol to ensure accountability and effectiveness.
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 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.

Where was the national agreement signed for regulations on cfc's?
The united nations.

What has been done to limit the destruction of the ozone layer?
To limit the destruction of ozone, many steps have been taken. Banning of CFC's is the main.
What year did cfc production reach its highest level?
the years of 1975 and 1987
What is CFC-11 and CFC-12?

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 have US down to prevent the ozone depetion?
The US has taken measures such as regulating the production and consumption of ozone-depleting substances through the Clean Air Act. Additionally, the US has ratified the Montreal Protocol, an international agreement aimed at phasing out the production and use of ozone-depleting chemicals. Public awareness campaigns and incentivizing environmentally friendly practices have also been key strategies in preventing ozone depletion.
What chemical have been banned in the most of the world because of their role in destroying the ozone layer?
Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) have been widely banned due to their destructive effect on the ozone layer. The Montreal Protocol is an international agreement aimed at phasing out the production and use of these chemicals to protect the ozone layer.
