The International Day for the Preservation of the Ozone Layer is globally recognized every year on September 16th. This day primarily commemorates 32 remarkable years of cooperation under the Montreal Protocol for the protection of our ozone layer and climate. It’s a reminder to the world that maintaining this momentum is crucial for the health of our planet and its inhabitants. The United Nations General Assembly officially announced September 16th as the International Day for the Preservation of the Ozone Layer in 1994. This date marks the signing of the Montreal Protocol on Substances that Deplete the Ozone Layer in 1987.
The Impact of The Montreal Protocol
The Montreal Protocol has made a significant influence on our environment. This pact led to the discontinuation of 99% of chemicals found in everyday items such as refrigerators and air conditioning units that are known to damage the ozone layer. By doing so, it effectively spearheaded the global fight against climate change by preventing an estimated 135 billion tonnes of carbon dioxide equivalent emissions from entering the atmosphere between 1990 and 2010.
Ozone Layer Recovery
A recent Scientific Assessment of Ozone Depletion in 2018 revealed some optimistic findings. Since 2000, parts of the ozone layer have begun to recover. The rate of recovery is between 1-3% per decade, which is a significant improvement and shows that our collective efforts are indeed making a difference.
Nature of Ozone
Comprised of three atoms of oxygen, ozone is found in two primary locations – the Earth’s upper atmosphere, or stratosphere, and at ground level in the troposphere. Depending upon where it’s located, ozone can either be good or bad.
Good ozone occurs naturally in the stratosphere and forms a layer that protects us from the sun’s harmful ultraviolet rays. This kind of ozone is crucial for life on earth.
On the other hand, bad ozone is found in the troposphere, near the ground level. This ozone is a result of chemical reactions between pollutants emitted by vehicles, power plants, industrial operations, refineries, and chemical plants with sunlight. Surface-level ozone is a dangerous air pollutant that has adverse effects on our health and environment.
Essential Facts about Ozone Layer
| Date proclaimed by UN | 16th September 1994 |
|---|---|
| Year Montreal Protocol was signed | 1987 |
| Ozone-depleting chemicals phased out | 99% |
| Estimated CO2 emissions prevented (1990-2010) | 135 billion tonnes |
| Ozone layer recovery rate since 2000 | 1-3% per decade |
Our Role in Preserving the Ozone Layer
The preservation of the ozone layer cannot be achieved by international organizations and protocols alone. Individual actions contribute significantly to this cause. By making conscious decisions such as using ozone-friendly products, we can all play a part in the healing of our planet. Our actions today will determine the health of our Earth for future generations.
