Which statement about the Montreal Protocol is accurate?

• A. It is a domestic law in the United States
• B. It applies only to North America
• C. It regulates refrigerant pricing
• D. It is an international agreement among many countries

Answer: (D)

The Montreal Protocol is an international treaty among many countries designed to protect the ozone layer by phasing out ozone-depleting substances such as CFCs and halons. It is not a domestic law in the United States, nor is it limited to North America, and it does not regulate refrigerant pricing. Instead, it creates legally binding obligations for participating countries to implement schedules, reporting, and controls on production and consumption of these substances, with support from the Multilateral Fund to help developing nations meet their obligations. This worldwide, negotiated framework and its evolving amendments make it an international agreement among many countries.
