Montreal Protocol aims at

• A. Control of $C{O}_2$ emission
• B. Reduction of ozone depleting substances
• C. Biodiversity conservation
• D. Control of water pollution

Answer 1

Answer: (B)

Reduction of ozone depleting substances

The 1987 Montreal Protocol on substances that deplete the ozone layer is a landmark agreement that has successfully reduced the global production, consumption, and emissions of ozone-depleting substances (ODSs). The treaty is structured around several groups of halogenated hydrocarbons that have been shown to play a role in ozone depletion. All of these ozone depleting substances contain either chlorine or bromine.

Therefore, the correct answer is option B.
