Ozone depletion, a grave environmental concern, refers to the gradual thinning of the ozone layer in Earth’s atmosphere, primarily due to the release of ozone-depleting substances (ODS). Recognizing the urgent need for international cooperation to address this issue, the Vienna Convention for the Protection of the Ozone Layer was adopted in 1985 as a framework for nations to work together to safeguard the ozone layer. Subsequently, the Montreal Protocol on Substances that Deplete the Ozone Layer, established in 1987, emerged as a landmark agreement, setting targets for the phase-out of ODS. Over the years, the Montreal Protocol has been hailed as a successful example of global environmental governance, leading to significant reductions in the production and consumption of ODS. Moreover, the Kigali Amendment to the Montreal Protocol, adopted in 2016, further strengthens these efforts by targeting hydrofluorocarbons (HFCs), potent greenhouse gases used mainly in refrigeration and air conditioning, thus addressing both ozone depletion and climate change simultaneously. These measures underscore the importance of international collaboration and regulatory frameworks in combating environmental threats on a global scale.<\/p>\n\n\n\n
