Fluorinated gases are not the only refrigerants available. Alternatives, such as ammonia or captured carbon dioxide, can replace these powerful greenhouse gases over time.

Pursuant to the Kigali accord signed in 2016, the replacement of HFC refrigerants with a mix of alternatives can result in a range of emissions reductions equivalent to 43.5-50.5 gigatons of carbon dioxide from 2020-2050.  Although the exact mix of alternatives is not projected and so the cost of adoption is not yet modeled, current and emerging refrigerants and appliances (including ammonia, carbon dioxide, and propane) can replace between 67%-82% of HFC refrigerants by 2050.
