Show answer

Answer: B. Montreal Protocol

Verdict

The answer is the Montreal Protocol. It governs the control and phasing out of ozone depleting substances.

Analysis

The Montreal Protocol on Substances that Deplete the Ozone Layer is a protocol to the Vienna Convention for the Protection of the Ozone Layer, and it phases out production and consumption of chlorofluorocarbons, halons and related compounds. The Kyoto Protocol, under the climate convention, deals with greenhouse gas emission commitments. The Nagoya Protocol, under the Convention on Biological Diversity, deals with access to genetic resources and benefit sharing. The Bretton Woods Conference of 1944 established the IMF and the World Bank and has nothing to do with the environment.

How to crack it

Every major environmental protocol hangs from a parent convention, and pairing them is the fastest way to keep them apart. Montreal hangs from Vienna and deals with ozone, Kyoto and Paris hang from the climate convention, Nagoya and Cartagena hang from the biodiversity convention. Learn the parent to protocol tree once and each distractor in a question like this identifies itself by which branch it sits on.
