(R134a replaced CFC-12 as the MAC refrigerant in the early 1990s due to the negative impact of CFCs on the Earth’s ozone layer. With its GWP of 1, it is also the refrigerant that has the least impact on climate. Baker (2007) Demonstration of an Energy-Efficient Secondary Loop HFC-152a Mobile Air Conditioning System.
