Which refrigerant is noted for having a high global warming potential (GWP)?

HFC-134a (Tetrafluoroethane) is recognized for having a high global warming potential (GWP). Its GWP value reflects its ability to trap heat in the atmosphere compared to carbon dioxide, making it a significant contributor to global warming. Due to its widespread use in air conditioning systems and refrigeration, the impact of HFC-134a on climate change has been a focal point in environmental discussions.

In contrast, R-22 and HCFC-123 have lower GWP values compared to HFC-134a, making them less problematic from an environmental perspective in terms of their potential impact on global warming. R-410A is also an HFC blend and has a high GWP, but it is generally regarded with slight differences compared to HFC-134a. However, it’s important to note that HFC-134a is widely acknowledged for its significant GWP in relevant regulatory and environmental conversations.
