Final answer:
The ban on the production or import of any HCFC refrigerant will take effect from a specific date depending on the country and its commitment to the Montreal Protocol agreement.
Step-by-step explanation:
The ban on the production or import of any HCFC refrigerant will take effect from a specific date depending on the country and its commitment to the Montreal Protocol agreement. The Montreal Protocol was established in 1987 to phase out CFC production in most countries and control the production and emission of chemicals that damage the ozone layer. The protocol has been successful in reducing CFCs since 1995, although some substances will not be phased out until 2030. India and China are currently the largest contributors to CFC emissions.
