Show Hint
The treaty protects the stratospheric ozone layer.
Updated On: Nov 12, 2026
- Biodiversity loss
- Water pollution
- Emission of ozone depleting substances
- \(\text{CO}_{2}\) emission
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
The Montreal Protocol was signed in 1987 and came into force in 1989.
Step 2: Aim
It is an international treaty to protect the ozone layer in the stratosphere. It asks countries to phase out ozone depleting substances like CFCs, halons and carbon tetrachloride.
Step 3: Compare the options
It is not about biodiversity or water pollution. Control of \(\text{CO}_2\) emission is linked to climate agreements such as the Kyoto Protocol.
Step 4: Conclusion
The Montreal Protocol controls emission of ozone depleting substances.
Final Answer:
The Montreal Protocol controls emission of ozone depleting substances. \[ \boxed{\text{(C) }\text{Emission of ozone depleting substances}} \]
