Automotive Industry: Transitioning to Low-GWP Refrigerants

The automotive industry is undergoing a significant shift in its choice of refrigerants for vehicle air conditioning systems. Traditionally, R-134a was the standard refrigerant; however, due to its high global warming potential (GWP), manufacturers are moving towards more environmentally friendly alternatives.

One such alternative is R-1234yf, which has a GWP significantly lower than R-134a. This transition aligns with global efforts to reduce greenhouse gas emissions. Notably, R-1234yf is now used in approximately 95% of new cars sold in the U.S., and an estimated 220 million cars worldwide are equipped with this refrigerant.

However, the European Union is considering a ban on R-1234yf due to environmental concerns, prompting the industry to explore natural refrigerants like CO₂ (R-744) and propane (R-290).

The shift towards low-GWP refrigerants is not only a regulatory response but also a commitment by the automotive industry to adopt sustainable practices and reduce its environmental footprint.
