d. Both a and b

e. None of the above

 

India on 13th Oct 2016 took the decision to eliminate the HCF-23 gas. The decision was made in line with the commitment to combat the threat emanating from climate damaging HFCs or hydrofluorocarbons

• The announcement was made during a meeting of parties to the Montreal Protocol where final negotiations are taking place to lower the use of HFCs by 2030
• HFC-23 gas is a potent greenhouse gas
• It has a global warming potential of 14800
• It is produced during the manufacture of a common refrigerant has HCFC-22
• If vented out in the environment, it is a threat to the environment
• HCFC stands for hydrochlorofluorocarbon
• Companies have taken the decision to internalise the cost of the environmental externality and create sufficient storage facility to ensure downtime and lack of release of HFC-23 in the atmosphere
• This move will check emissions of HFC-23 equivalent to 100 MT of CO₂ over the next 15 years
• The Montreal Protocol on Substances that Deplete the Ozone Layer was designed to reduce production and consumption of ozone depleting sustained to reduce their abundance in the environment and protect the fragile ozone layer of the earth
• The original Montreal protocol was signed on Sept 16, 1987 and entered into force on Jan 1, 1989
• The Montreal Protocol includes a unique adjustment provision enabling parties to protocol to respond quickly to the new scientific information and to adjust the reductions on chemicals covered by the Protocol
• The adjustments are then automatically applicable to nations who ratified the protocol– it has been ratified by 197 parties
