i. In response to the recognized detrimental effects of ozone depletion, the Montreal Protocol, an international treaty signed in 1987 in Montreal (Canada), stands as a pivotal measure to regulate the emission of ozone-depleting substances.
ii. Subsequent to its inception, additional endeavors and protocols have been established, delineating distinct roadmaps for both developing and developed nations to curtail the emission of ozone-depleting compounds such as CFCs.
iii. The Montreal Protocol places its primary focus on chloro or bromo derivatives of hydrocarbons, identified as the primary contributors to ozone layer depletion.
iv. It establishes a mechanism to systematically reduce and phase out the global production and consumption of substances known to deplete the ozone layer.
v. The Montreal Protocol has proven effective in significantly diminishing the global production, consumption, and emissions of substances responsible for ozone layer depletion.
vi. Positive indications of stratospheric ozone recovery have emerged. Without the implementation of the Montreal Protocol, it is plausible that ozone depletion would be considerably more severe than observed today, underscoring the indispensable nature of this international agreement.
