In the section below, we provide data on global emissions of ozone-depleting substances. emissions are not necessarily synonymous with the production/consumption of these materials; In our Data Quality & Definitions section, we explain the difference between these two measures. The graph shows the level of natural emissions (which was roughly consistent during this period) and total emissions, which are the sum of natural and man-made emissions. Here we see a clear trend towards reducing the peak growth of ozone-depleting emissions, with a rapid increase in emissions (more than three times) from 1960 to the late 1980s, followed by an equally rapid reduction in the following decades. By 2010, emissions had returned to their 1960 levels. This is largely the result of international regulatory agreements and concerted actions to phase out the production and consumption of these substances (which have then been discussed in this article). As a result of the international agreement, the hole in the antarctic ozone layer is slowly recovering.  Climate projections indicate that the ozone layer will return to its 1980 level between 2050 and 2070.    The success of the Montreal Protocol is due to its effective proposals for burden-sharing and solutions, which have helped to mitigate regional conflicts of interest in relation to the shortcomings of the Kyoto Protocol`s overall regulatory approach.  However, comprehensive regulation was established before a scientific consensus was established and general public opinion was convinced of the imminent potential risks associated with the ozone layer.   The Fund is managed by an Executive Committee composed equally of seven industrialized countries and seven countries in accordance with Article 5, elected annually by an Assembly of the Contracting Parties. Each year, the Committee reports on its activities to the Assembly of Parties. The Multilateral Fund`s field work in developing countries is carried out by four implementing agencies that have concluded contractual agreements with the Executive Committee: Since the entry into force of the Montreal Protocol, atmospheric concentrations of major chlorofluorocarbons and related chlorinated hydrocarbons have decreased or decreased.
 Halon concentrations have continued to increase due to the release of halons currently stored in fire extinguishers, but their rate of increase has slowed and their frequency is expected to decrease by about 2020. . . .
