to speed up the section-out of production and consumption of HCFCS. The most important remaining threats to the ozone layer are local weather change and its effects on the ozone layer, emissions from present banks of ozone depleting substances and the rise of N2O emissions. The Vienna Convention sets out a framework for scientific and technical co-operation associated to the monitoring of the ozone layer whereas the Montreal Protocol controls the manufacture, use and buying and selling of ozone-depleting substances.
More than 30 years after the Montreal Protocol, NASA scientists documented the first direct proof that Antarctic ozone is recovering because of the CFC part-down: Ozone depletion within the region has declined 20 % since 2005. Molina and Rowland’s work received hanging
