THE SECRETARY-GENERAL

MESSAGE ON THE INTERNATIONAL DAY
FOR THE PRESERVATION OF THE OZONE LAYER
16 September 2003
The international community's
response to the destruction of the ozone layer, the shield that protects the
earth from the sun's deadly ultraviolet radiation, has been impressive. The
Montreal Protocol on Substances that Deplete the Ozone Layer is working.
Recent findings by the world's
leading atmospheric scientists show that the level of chlorine in the upper
atmosphere is at or near its peak. As a result, the rate of ozone layer
depletion in the stratosphere has been observed to be declining. We are now
seeing the first signs of the recovery of the ozone layer.
However, we cannot be
complacent. The ozone layer remains depleted above the Antarctic and the Arctic,
as well as in the midlatitudes of both hemispheres of the earth. The same
scientists warn that the ozone layer will remain particularly vulnerable during
the next decade or so. As we look to the future, even greater political
commitment and further action is required to ensure full compliance with the
Montreal Protocol by developed and developing countries alike.
There are several challenges to
be met. For instance, all countries must ratify the Amendments to the Montreal
Protocol. The developing country Parties that entered their
"compliance" period in 1999 must phase out the use of many ozone
depleting substances within specified time schedules. The illegal trade in
chlorofluorocarbons must be curbed. Parties to the Montreal Protocol need to
meet the challenges involved in phasing out methyl bromide under the Copenhagen
Amendment of 1992, as well as in evaluating and approving those critical uses
allowed under the Montreal Protocol. Alternatives to some current uses of methyl
bromide must still be found. And more research is required on the relationship
between depletion of the ozone layer and climate change.
So while we may be gratified
with the progress that has been made through international cooperation, we must
not be satisfied until the preservation of the ozone layer is assured. Only then
will we be able to say that we have saved our sky for future generations.
