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

Halocarbons The main concern with the family of man made halocarbons has been their impact on the destruction of the stratospheric ozone layer.

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.

Noting that dealing with obsolete equipment at the end of its useful life and the remaining ozone depleting substances was important for the protection of the ozone layer, he pointed out that the replacement of such equipment and the recovery and destruction of the ozone depleting substances it contained posed technical and financial challenges for Parties operating under Article 5.

Tropospheric Ozone Tropospheric ozone has just been recognized as a potentially important greenhouse gas.

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.

The primary ozone related opportunity suggested in the special report related to the reduction of emissions from banked ozone depleting substances through improved containment of substances reduced charge of substances in equipment end of life recovery and recycling or destruction increased use of alternatives with zero ozone depleting potential (ODP) and, ideally, a low or negligible global warming potential use of not in kind technologies or a combination of the above.

Unbridled pollution, the destruction of the ozone layer, deforestation, rising sea levels in a word, the ceaseless deterioration of the environment require us all to heighten our awareness of those global threats.
