Question

UPSC Prelims 2015 Question:

Which one of the following is associated with the issue of control and phasing out of the use of ozone-depleting substances?

  1. 1. Bretton Woods Conference
  2. 2. Montreal Protocol
  3. 3. Kyoto Protocol
  4. 4. Nagoya Protocol

Answer (Detailed Solution Below)

Option 2: Montreal Protocol

Detailed Solution

Explanation:

  • The Montreal Protocol on Substances that Deplete the Ozone Layer is the landmark multilateral environmental agreement that regulates the production and consumption of nearly 100 man-made chemicals referred to as ozone depleting substances (ODS).
  • Adopted on 16 September 1987, the Protocol is to date one of the rare treaties to achieve universal ratification.
  • The Montreal Protocol phases down the consumption and production of the different ODS in a step-wise manner, with different timetables for developed and developing countries (referred to as “Article 5 countries”). Under this treaty, all parties have specific responsibilities related to the phase out of the different groups of ODS, control of ODS trade, annual reporting of data, national licensing systems to control ODS imports and exports, and other matters. Developing and developed countries have equal but differentiated responsibilities, but most importantly, both groups of countries have binding, time-targeted and measurable commitments.

Therefore, option (2) is the correct answer.
