What is the main objective of the Montreal Protocol?

The main objective of the Montreal Protocol is to phase out substances that deplete the ozone layer. This international treaty, adopted in 1987, established a commitment among countries to protect the ozone layer by reducing and eventually eliminating the use of various ozone-depleting substances (ODS), including chlorofluorocarbons (CFCs) and halons. Over time, the protocol has proven effective in facilitating the global reduction of these harmful substances and has led to significant recovery of the ozone layer.

The essence of the Montreal Protocol lies in its focus on environmental protection and the collaboration of nations to address a critical global issue. This makes it a cornerstone of international environmental law aimed specifically at halting the damage to the ozone layer, which is crucial for protecting life on Earth from harmful ultraviolet radiation.

In this context, the other options fail to capture the primary goal of the Protocol, as they do not directly address the issue of ozone depletion.
