Which refrigerant has the lowest global warming potential (GWP)?

Explanation:
Global warming potential tells you how much heat a refrigerant traps in the atmosphere over a set time compared with carbon dioxide. A lower GWP means less potential to contribute to climate warming if the refrigerant is released. R-1234yf has a GWP of about 4, which is extremely low compared with the others listed (R-22 is around 1800, R-410A about 2080, and R-12 near 1000). Because of this, it has the smallest environmental impact in terms of global warming potential, making it the best choice when the goal is the lowest GWP.
