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

1. 50%

2. 75%

3. 95%

4. 100%

The correct answer is: 95%

The Montreal Protocol, established in 1987, was a significant international treaty aimed at protecting the ozone layer by phasing out the production and consumption of substances that deplete it, particularly chlorofluorocarbons (CFCs) and halons. The protocol's comprehensive framework led to the commitment of countries to eliminate nearly all of their production and use of these harmful substances. By 2023, the protocol had achieved an impressive outcome, with approximately 95% of the world’s production capacity for CFCs and halons phased out. This includes the actions taken by signatory nations to restrict these chemicals, thus demonstrating the global commitment to environmental protection. The remaining percentage represents the exceptions, which are very limited and often involve specific uses that have been permitted under strict regulations. Such success underscores the importance of international cooperation in addressing global environmental issues and is a significant milestone in the context of the protocol's objectives.
