With the urgent matter of environmental protection, the replacement of HCFCs on a large scale around the world is needed day by day. The Parties to Montreal Protocol at the 19th Meeting proposed and passed the Amendment that expedites to phase out HCFCs. To date, natural refrigerant, HFCs and their mixture, all these are the main refrigerant replacement to HCFCs. The ODP of HFCs is zero, but most of which have higher global warming potential and the lifetime in the atmosphere is longer. A large consumption of HCFCs will contribute to global warming. In the long term, HFCs refrigerant will also be phased out. Most HCs are flammable and dangerous when used. The European Union passed F-gas regulation on June 14, 2006, which regulated all automotive air conditioning systems on new registered platforms could not use any refrigerants with GWP of more than 150 from the year 2011. By the end of 2017, all the automotive air conditioning systems were banned to use refrigerants with GWP of more than 150. The EPA also planned to phase out R134a refrigerant. All new vehicles and light duty trucks sold in the U.S.market were banned to use R134a commonly used in the automotive industry after 2021. A similar treaty for medium and heavy duty trucks will be released this year on account of the EPA regulations, which only limited cars and light duty trucks. Therefore, all the new vehicles sold around the US will change R1234yf as the replacement of R134a by the end of 2021. Yet a part of vehicles for export can still be equipped with R134a air conditioning systems as of 2025. The Japan METI regulated to limit high GWP HFC used in automotive air conditioners, domestic refrigeration, commercial refrigeration, and foam step by step from 2015 to 2025. Korea has carried out a credit score policy in replacing HFC for automotive air conditioners since 2016.
