Concerns over the depletion of the stratospheric ozone layer because of refrigerants and foaming agents used in CCEs have spurred a global effort to phase out the production and consumption of CFC and many others (i.e. HCFCs). Subsequent concerns over global warming have reinforced the need to eliminate these substances because they are also potent greenhouse gases. Before the 1987 Montreal Protocol, excessive use of CFCs including HCFCs in refrigeration, air conditioning, building insulations, and aerosols led to the depletion of the ozone layer. The Montreal Protocol was created to protect the diminishing ozone layer and led to a large increase in the use of hydrofluorocarbons (HFCs) instead of CFCs. At the time of the Montreal Protocol’s adoption, HFCs were thought to be acceptable substitutes for ozone layer-depleting CFCs. In 2016, the international community adopted the Kigali Amendment to the 1987 Montreal Protocol, to gradually phase out the use of HFCs, hydrofluorolefins, hydrocarbons, ammonia, and carbon dioxide too.
Although CFC gases are not present in newer versions of the CCE procured by the immunization program in many LMICs, but they may be present in the older CCEs. At the time of the auction sale, it is the responsibility of the auctioning office to manage CFC gases if present in the cold chain equipment.
Therefore, I am looking for practical expericnes if anyone have that can be applied in Nepal for the management of CFC gas.
