How did the government respond to the ozone depletion?
How did the government respond to the ozone depletion?
Formally known as the “London Amendments to the Montreal Protocol”, this landmark agreement brought in all nations, under fair and equitable terms, to phase out the production of CFCs, rescue the ozone layer and save millions of lives.
What is the overall effect of the Montreal Protocol?
The Montreal Protocol has been successful in reducing ozone-depleting substances and reactive chlorine and bromine in the stratosphere. As a result, the ozone layer is showing the first signs of recovery.
What did the Montreal Protocol ban and what are its effects?
The Montreal Protocol sets binding progressive phase out obligations for developed and developing countries for all the major ozone depleting substances, including chlorofluorocarbons (CFCs), halons and less damaging transitional chemicals such as hydrochlorofluorocarbons (HCFCs).
What was the result of the 1987 Montreal Protocol?
It is a monumental achievement. The Montreal Protocol, finalized in 1987, is a global agreement to protect the stratospheric ozone layer by phasing out the production and consumption of ozone-depleting substances (ODS).
What did the government do about CFC?
It took only 2 years from the discovery of the ozone layer in 1985 for governments to agree to a global ban on the use of CFCsand a further 2 years for it to come into effect. The Montreal Protocol is the only treaty ever to achieve universal ratification; with 197 countries enforcing the ban on CFCs.
Which of the following are affected by the loss of ozone?
Ozone layer depletion causes increased UV radiation levels at the Earth’s surface, which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders.
When did the Montreal Protocol came into effect?
1989
The landmark agreement was signed in 1987 and entered into force in 1989. The parties to the Protocol meet once a year to make decisions aimed at ensuring the successful implementation of the agreement.

Was the Montreal Protocol successful Why or why not?
The Montreal Protocol has been successful in slowing and reversing the increase of ozone-depleting gases (halogen source gases) in the atmosphere. An important measure of its success is the change in the value of effective stratospheric chlorine.
What is the importance of Montreal Protocol and Kyoto Treaty?
The 1987 Montreal Protocol – restricting the use of ozone-depleting substances – has helped both to reduce global warming and to protect the ozone layer. The benefit to climate achieved by the Montreal Protocol alone at present greatly exceeds the initial target of the Kyoto Protocol.
How has the Montreal Protocol of 1987 impacted climate change?
As such, the Montreal Protocol has resulted in two major changes to global atmospheric composition that have relevance to Earth’s climate: (1) ozone depletion has reversed and a recovery in the ozone hole is now underway, and (2) several potent varieties of greenhouse gases, most notably CFC-11 and CFC-12, have been …
How did the Montreal Protocol reverse ozone depletion?
Montreal Protocol, a landmark agreement banning CFCs and other ozone-depleting substances. The agreement set a mandatory timetable for the phasing out of main ozone-depleting substances and provided money to developing countries to help them phase out these substances.
