The Earth's ozone layer is expected to recover within the next 40 years as ozone-depleting chemicals are being phased out of use, a panel of international experts backed by the U.N. says. The panel, which publishes a new ozone layer report every four years, credits the phasing out out of nearly 99% of ozone-depleting chemicals for the improvement.
The agency said the Montreal Protocol, a landmark global agreement to phase out harmful chemicals, has significantly aided the recovery of the ozone layer. The Montreal Protocol entered into force in 1989 and regulates nearly 100 manmade chemicals that damage the ozone layer.
"The impact the Montreal Protocol has had on climate change mitigation cannot be overstressed," said Meg Seki, the executive secretary of the U.N. Environment Programme's Ozone Secretariat. "Over the last 35 years, the Protocol has become a true champion for the environment."
