Question

Montreal protocol is related to :

• A. Global warming
• B. Ozone layer depletion
• C. Sustainable development
• D. Food security

Hint:

Associate Montreal Protocol directly with CFC phase-out and Ozone Layer protection, while associating Kyoto/Paris agreements with Carbon dioxide and Global Warming.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
International environmental treaties and protocols are established by global governing bodies to address planetary-scale environmental crises, such as climate change, biodiversity loss, and atmospheric degradation.

Step 2: Detailed Explanation:
The Montreal Protocol on Substances that Deplete the Ozone Layer is a landmark international treaty designed to protect the stratospheric ozone layer.
Signed in September 1987 and entered into force in 1989, it aimed to progressively phase out the production, consumption, and emissions of Ozone Depleting Substances (ODS).
These substances primarily include chlorofluorocarbons (CFCs), halons, carbon tetrachloride, and methyl chloroform, which release chlorine and bromine atoms into the stratosphere, destroying ozone molecules.
Let us review other major international environmental agreements:
1. Kyoto Protocol Paris Agreement: Specifically targeted at reducing greenhouse gas emissions to mitigate global warming and climate change.
2. Rio Declaration Agenda 21: Focused extensively on promoting global sustainable development.
The Montreal Protocol is globally recognized as one of the most successful international environmental treaties ever enacted, resulting in the gradual recovery of the Antarctic ozone hole.

Step 4: Final Answer:
Thus, the Montreal Protocol is related to Ozone layer depletion.
