In the path of recovery, it will take around fifty years for the ozone layer to go back to the stage it was in 1970s," said Atul Bagai, senior regional coordinator, United Nations Environment Programme(UNEP).
He said the Chlorofluorocarbon (CFC) and other halogenated ozone depleting substances (ODS), mainly responsible for man-made chemical ozone depletion, were phased out in 2010.
