Answer: D
Explanation
● The Montreal Protocol on Substances that Deplete the Ozone Layer is an international
environmental treaty that regulates the production and consumption of nearly 100
man-made chemicals referred to as ozone depleting substances (ODS) including
chlorofluorocarbons (CFCs), halons and hydrochlorofluorocarbons (HCFCs). Hence,
all the options are correct.
● The stratospheric ozone layer protects humans and the environment from harmful
levels of ultraviolet radiation from the sun. The widespread use of ODS had caused a
hole in the Ozone layer of the atmosphere, which allowed some harmful radiation to reach
the earth. These radiations were considered potential health hazards.
● Adopted in 1987, the Montreal Protocol is the only UN treaty that has been ratified by
every country.
● 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 along
with binding, time-targeted and measurable commitments.
● The Montreal Protocol has been a far more effective and successful agreement than the
climate change instruments. It has already resulted in the phase-out of nearly 99% of
ozone-depleting substances.
About Hydrofluorocarbons
● Hydrofluorocarbons (HFCs) are a group of industrial chemicals primarily used for cooling
and refrigeration.
● HFCs are powerful greenhouse gases and a substantial number are short-lived climate
pollutants with a lifetime of between 15 and 29 years in the atmosphere.
● HFCs are widespread in air conditioners, refrigerators, aerosols, foams and other
products.
● HFCs were introduced as non-ozone depleting alternatives to support the timely phase out
of CFCs and HCFCs under Montreal Protocol.
● While these chemicals do not deplete the stratospheric ozone layer, HFCs were found to be
extremely potent in causing global warming. Some of them have high Global Warming
Potentials (GWPs) ranging from 12 to 14,000.
● So, the HFCs solved one problem, but were contributing in a major way to another. But these
could not be eliminated under the original provisions of Montreal Protocol which was meant
to phase-out ozone-destroying chemicals only. The Kigali Amendment enabled the Montreal
Protocol to mandate the elimination of HFCs as well.
Kigali Agreement
● The Parties to the Montreal Protocol reached an agreement at their 28th Meeting of the
Parties in 2016 in Kigali, Rwanda. The Agreement particularly aims at phasing out the
production and consumption of Hydrofluorocarbons which were first introduced as a
substitute to ODSs namely CFCs and Hydrochlorofluorocarbons HCFCs.
● Parties to the agreement agreed to curtail the use of HFC by at least 85 per cent before the
middle of this century. Countries have different timelines to do this. India has to achieve this target by 2047 while the developed countries have to do it by 2036. China and some
other countries have a target of 2045.
● The agreement came into force on 1st January 2019 and has been ratified by more than 130
countries (including India) so far.
● Kigali Agreement legally binds the signatory countries with non-compliance measures.
