Show Solution
Verified By Collegedunia
The Correct Option is A
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 stratospheric ozone layer. It requires nations to phase out ozone depleting substances such as CFCs, halons and carbon tetrachloride.
Step 3: Other issues
Global warming is covered by the Kyoto Protocol and the Paris Agreement, not by this treaty.
Final Answer:
The Montreal Protocol is concerned with controlling emission of ozone depleting substances. \[ \boxed{\text{(A) }\text{Control emission of ozone depleting substances}} \]
