Which aspect of refrigerants does the Montreal Protocol primarily address?

• A. Global warming potential only
• B. Ozone layer protection
• C. Safety in handling
• D. Efficiency of refrigerants

Answer: (B)

The Montreal Protocol primarily addresses the protection of the ozone layer by phasing out the production and consumption of substances that deplete it. Established in 1987, this international treaty was a response to growing scientific evidence linking chlorofluorocarbons (CFCs) and other ozone-depleting substances to the thinning of the ozone layer, which plays a crucial role in protecting Earth from harmful ultraviolet radiation. This focus on ozone layer protection has led to significant reductions in the use of these harmful substances, highlighting the importance of the protocol in environmental conservation efforts. In relation to other options, while attributes such as global warming potential, safety, and efficiency of refrigerants are important aspects of refrigerant management and environmental impact, they fall outside the specific scope of the Montreal Protocol. The Protocol directly targets ozone-depleting substances rather than broader refrigerant characteristics.
