Difficulty: EasyClimate Change, Global Warming and Ozone Layer Depletion

Which international treaty was specifically adopted to protect the stratospheric ozone layer by phasing out the production and consumption of ozone-depleting substances (ODS)?

  1. Montreal ProtocolAnswer
  2. B
    Kyoto Protocol
  3. C
    Ramsar Convention
  4. D
    Basel Convention

Answer

The Montreal Protocol is the international treaty adopted specifically to protect the ozone layer by phasing out ozone-depleting substances.
The Montreal Protocol on Substances that Deplete the Ozone Layer, adopted in 1987, is an international agreement designed to protect the stratospheric ozone layer by phasing out the production and consumption of ozone-depleting substances such as chlorofluorocarbons (CFCs) and halons.

Step-by-Step Solution

1
Identify the primary objective of the question.
The target is to identify the global environmental agreement dedicated to combating ozone layer depletion by limiting ozone-depleting chemicals.
Different international environmental protocols focus on distinct ecological domains.
2
Match the treaties to their respective core mandates.
The Montreal Protocol (1987) regulates chemicals like chlorofluorocarbons (CFCs) to facilitate stratospheric ozone recovery.
Chemicals such as CFCs breakdown ozone molecules upon exposure to ultraviolet solar radiation in the stratosphere.
