THE GLOBAL TRENDS FOR THE PROTECTION OF THE OZONE-LAYER

The discovery of the ozone hole over the Antarctica and various research works to find the cause of such hole revealed that the present regulation of ozone depleting substances may not be sufficient for the adequate protection of the ozone layer. On the basis of the latest findings indicated by the world scientists in the four assessment panel reports pursuant to the Article 6 of the Montreal Protocol (science, environmental effects, technical and economic aspects) and other information, the Parties to the Montreal Protocol adopted the amendment and adjustment of the Protocol in June 1990, at the Second Meeting of the Parties to the Montreal Protocol. This document briefly reviews the latest scientific and technical information for the amendment and adjustment of the Protocol, and the major thrusts of the amendment and adjustment, including elimination of the production and consumption of controlled CFCs by the year 2000, and the problems which are still left before us to be solved.
