What percentage of the world's production capacity for CFCs and halons have signed the Montreal Protocol?

The Montreal Protocol, adopted in 1987, is a landmark international treaty aimed at phasing out substances that deplete the ozone layer, including chlorofluorocarbons (CFCs) and halons. The protocol has been remarkably successful, as it has garnered widespread support from countries around the world. The fact that 95% of the world's production capacity for these harmful substances has signed the Montreal Protocol underscores the global commitment to protecting the ozone layer and mitigating environmental damage.

This high percentage indicates that virtually all major producers of CFCs and halons have agreed to adhere to the regulations set forth by the treaty, which helps ensure the reduction and eventual elimination of these ozone-depleting chemicals. The widespread acceptance of the protocol is a testament to the concerted international effort to address environmental issues and highlights the importance of collaboration among nations to achieve significant ecological outcomes. This commitment plays a crucial role in the ongoing recovery of the ozone layer and underscores the effectiveness of multilateral environmental agreements.
