(a)Bretton Woods Conference
(b)Montreal Protocol

Attempt This Question
Not attemptedCorrect Answer: (b) Montreal Protocol
The Montreal Protocol on Substances that Deplete the Ozone Layer (adopted 1987) specifically regulates and progressively phases out the production and consumption of ozone-depleting substances such as CFCs and HCFCs. The other instruments deal with international finance (Bretton Woods), greenhouse-gas mitigation (Kyoto) and genetic resources (Nagoya). Hence option (b) is correct.
