What did the Montreal Protocol do?
The Montreal Protocol on Substances that Deplete the Ozone Layer (the Montreal Protocol) is an international agreement made in 1987. It was designed to stop the production and import of ozone depleting substances and reduce their concentration in the atmosphere to help protect the earth’s ozone layer.
Who first discovered the ozone layer?
The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson.
Has the Montreal Protocol been successful?
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.
Which year Montreal Protocol signed?
1987
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).
Why was the Montreal Protocol so effective?
The Montreal Protocol has been successful in reducing ozone-depleting substances and reactive chlorine and bromine in the stratosphere. This is because once released, ozone-depleting substances stay in the atmosphere for many years and continue to cause damage.
How big was the ozone hole in 1985?
The maximum depth of the hole that year was 194 Dobson Units (DU)—not far below the previous historical low. For several years, the minimum concentrations stayed in the 190s, but then the minimums rapidly grew deeper: 173 DU in 1982, 154 in 1983, 124 in 1985.
What is the current status of the Montreal Protocol?

When was the Montreal Protocol last updated?
On October 15, 2016, with the United States’ leadership, 197 countries adopted an amendment to phase down HFCs under the Montreal Protocol in Kigali, Rwanda. Under the amendment, countries committed to cut the production and consumption of HFCs by more than 80 percent over the next 30 years.
What is Kyoto Protocol Montreal Protocol?
Through the 1997 Kyoto Protocol, the industrialised countries (responsible for over 70% of the global emissions of “greenhouse gases”) have committed themselves (not yet in a binding way) to reduce their emissions by 5.2% compared to those of 1990 by 2008-2012. …
