According to a United Nations (UN)-backed assessment, our planet's ozone layer will be totally recovered by 2066 if we continue our current trends of lowering the usage of ozone-depleting compounds.
The Montreal Protocol, which was unanimously approved in 1987, classified approximately 100 compounds as being harmful to the health of our planet's ozone layer, including chlorofluorocarbons (CFCs) commonly found in aerosols.
The protocol intended to regulate the use of these compounds, and the Scientific Assessment Panel to the Montreal Protocol on Ozone Depleting Substances produced a progress report every four years.
The most recent assessment, which will be given at the American Meteorological Society's 103rd annual conference, indicates that we're on the right road in terms of rebuilding the ozone layer.
According to the data, it is expected to be recovered for the majority of the planet by 2040, for the Arctic region by 2045, and for the Antarctic by 2066.
The report also acknowledged positive progress in the decrease of hydrofluorocarbons (HFCs), which have been employed as less-harmful-to-ozone substitutes to CFCs but are still deemed hazardous for the environment.

Although these HFCs do not directly degrade the ozone layer's integrity, they do contribute to the global warming problem, and the Montreal Protocol was updated to include a reduction objective for these HFCs, which appear to have had progressively decreased usage over the years, according to the paper.
According to calculations, if we continue on our current path, we will escape around 0.3 to 0.5 degrees Celsius (0.54 to 0.9 degrees Fahrenheit) by the year 2100.
"The fact that ozone recovery is on pace, according to the most recent quadrennial report, is excellent news. The Montreal Protocol's impact on climate change mitigation cannot be understated "Meg Seki, Executive Secretary of the UN Environment Program's Ozone Secretariat, agreed.
"Over the last 35 years, the Protocol has evolved into a true environmental champion."
The Globe Meteorological Organization's Secretary-General, Professor Petteri Taalas, also stated that these beneficial accomplishments should serve as motivation for the rest of the world to continue working toward positive environmental outcomes.
"The action on ozone sets a precedent for climate action. Our accomplishment in phasing out ozone-depleting chemicals demonstrates what can and must be done urgently to transition away from fossil fuels, reduce greenhouse emissions, and hence limit temperature rise "He stated.
