Which one of the following is associated with the issue of control and phasing out of the use of ozone-depleting substances?
Correct Answer: B. Montreal Protocol
Explanation: The Montreal Protocol is the international treaty specifically associated with the issue of control and phasing out of the use of ozone-depleting substances (ODS). It was signed in 1987 and entered into force in 1989 with the objective of protecting the ozone layer by reducing and eventually eliminating the production and consumption of substances responsible for ozone depletion, such as chlorofluorocarbons (CFCs) and halons. The protocol sets binding obligations for all member countries to phase out these harmful substances in a time-bound and stepwise manner, with differentiated responsibilities and timelines for developed and developing countries. Therefore, the correct answer is (b) Montreal Protocol. Related
