In the 1970s, emissions of chlorofluorocarbons (CFCs) in industrial applications were linked to destruction of the ozone layer.

However, stratospheric ozone destruction in the polar regions and the consequent rise in dangerous ultraviolet radiation is still occurring at near record levels.

C. Draft decision XVII C Technical and financial implications of the environmentally sound destruction of concentrated and diluted sources of ozone depleting substances

Another representative recalled the discussion on destruction technologies and observed that the disposal of recovered ozone depleting substances was an important matter for decision.

Concerns that destruction of the ozone layer could result in significant harm to human health and the environment led governments in 1985 to adopt a framework agreement, the Vienna Convention for the Protection of the Ozone Layer, to begin addressing the problem.

Technical and financial implications of the environmentally sound destruction of ozone depleting substances In 2002, the Technology and Economic Assessment Panel's Task Force on Destruction Technologies identified a number of emerging technologies that, while theoretically effective, had not yet demonstrated evidence of technical capability.

In addition to the above noted activities, scientific and other research related activities that were reported on included studies on ozone variation, temperature influences on ozone, the interaction between ozone and climate and climactic profiles of ozone.

illegal trade in ozone depleting substances

Illegal trade in ozone depleting substances is controlled by the 1987 Montreal Protocol on Substances that Deplete the Ozone Layer, which aims to gradually reduce and finally phase out all ozone depleting substances.

Those Parties who celebrated Ozone Day this year are to be commended and all Parties are urged to consider celebrating Ozone Day as a way of promoting awareness both of the ozone regime and of the continuing need for vigilance in our efforts to protect the ozone layer.

Ozone Day celebration As noted above, the Secretariat helped celebrate Ozone Day in 2005 in Vienna, through the conduct of a seminar on the ozone regime and the reception hosted by the Government of Austria.

All of these ozone depleting substances contain either chlorine or bromine (substances containing only fluorine do not harm the ozone layer).

on Substances that Deplete the Ozone Layer

Ozone is tri atomic oxygen, O3 ozone molecules absorb harmful UV light in the atmosphere before it reaches the surface of the earth.

Future ozone concentrations are mainly driven by the changes in stratospheric halogen loading, with ozone recovery occurring after the peak of halogen loading.

Monitoring and preventing illegal trade in ozone depleting

Likewise, export licensing systems or bans for re exporting ozone depleting substances were rare, as were import prohibitions for equipment containing ozone depleting substances.

Customs and law enforcement officer training was also essential but it had to be backed up by the procurement of equipment and appropriate technology to help the officers with checking and analysis, and for the destruction of seized ozone depleting substances.

They are implicated in the formation of ozone holes.

Decision XVII __ Preventing illegal trade in ozone depleting substances

Decision XVI 33. Illegal trade in ozone depleting substances

The Montreal Protocol on Substances that Deplete the Ozone Layer of the Vienna Convention for the Protection of the Ozone Layer provides the framework for Parties to phase out the production and consumption of ozone depleting substances (ODS) according to a strict time table.

The anion has the V shape of the ozone molecule.

Among these threats, ozone depletion is high on the agenda.

The activities noted above were generally designed to increase awareness of the Montreal Protocol, the ozone issue and the methods available to minimize emissions of ozone depleting substances.
