International. According to the report "Scientific Assessment of Ozone Depletion: 2022", it is concluded that the recovery of the ozone layer is on track, helping to avoid global warming by 0.5 °C.
Among the main achievements of the Montreal Protocol, described in the document, are: the actions taken to reduce the presence in the atmosphere of substances that deplete the ozone layer, as well as the recovery of the stratospheric ozone layer; the progress of the total ozone column (TCO) in Antarctica continues to recover, despite significant year-on-year variability in size, strength and longevity; the decline in ODS emissions and the full recovery since 1996, when there was a low confidence level.
Moreover, the TCO is expected to return to 1980 values around in the Arctic by 2066 and in Antarctica around 2045.
The research and publication is under the aegis of UNEP, which is the United Nations Environment Programme, an Implementation Agency of the Multilateral Fund of the Montreal Protocol on Substances that Deplete the Ozone Layer.
It should be noted that this publication has contributions from the World Meteorological Organization, UNEP, the National Oceanic and Atmospheric Administration, the National Aeronautics and Space Administration and the European Commission.
This publication, which has been replicated globally by the different international and local media, represents an advance in environmental care and the positive result of the regulation of substances, which shows that joint work can indeed repair the damage caused to the ozone layer.
