Question

Which global agreement specifically targets the phase-out of Ozone Depleting Substances (ODS)?

• A. Kyoto Protocol
• B. Paris Agreement
• C. Montreal Protocol
• D. Basel Convention

Hint:

{Montreal Protocol (1987)} → Protects the ozone layer by phasing out {CFCs and other ODS}. Remember: {Montreal = Ozone protection}.

Answer 1

The Correct Option is C

Concept: Ozone Depleting Substances (ODS) are chemicals that damage the ozone layer in the stratosphere. Examples include chlorofluorocarbons (CFCs), halons, carbon tetrachloride, and methyl chloroform. These substances release chlorine or bromine atoms in the atmosphere, which break down ozone molecules and reduce the protective ozone shield. To address this global environmental problem, countries signed the Montreal Protocol in 1987. This international treaty aims to phase out the production and consumption of ozone-depleting substances worldwide.
Step 1: Identifying the treaty related to ozone protection.
The Montreal Protocol on Substances that Deplete the Ozone Layer was adopted in 1987 and is considered one of the most successful environmental agreements. It established a timetable for reducing and eventually eliminating the use of ODS.
Step 2: Eliminating the other options.

• Kyoto Protocol: Focuses on reducing greenhouse gas emissions to combat climate change.
• Paris Agreement: A global treaty addressing climate change and limiting global warming.
• Basel Convention: Regulates the transboundary movement and disposal of hazardous wastes.

Since the agreement that specifically targets the phase-out of ozone-depleting substances is the Montreal Protocol, it is the correct answer.
