Effective implementation of the Montreal Protocol on Substances that Deplete the Ozone Layer can only be achieved if a sound informational basis concerning the current status of the phase out of ozone-depleting substances (ODS) exists. Information on production and consumption of ODS is submitted to the Ozone Secretariat in Nairobi by the Parties to the Montreal Protocol.
