Hydrofluoroolefin (HFO) 1234yf was the result of a multi-year R&D program and has undergone extensive testing since August 2007. In comprehensive toxicity testing, it was found to be acceptable for use.

A global solution, HFO-1234yf is able to provide efficient and effective cooling in even the hottest regions.

As a near drop-in replacement for the current refrigerant R-134a, it allows fast and easy adoption for automakers.

Its Global Warming Potential (GWP) of 4 is well below the EC regulations of 150.

HFO-1234yf has an atmospheric lifetime of only 11 days -- compared to 13 years for R-134a and more than 500 years for carbon dioxide.

Autos using highly energy-efficient refrigerant HFO-1234yf will use less fuel and have fewer emissions than those that use less-efficient alternatives.

HFO-1234yf is safe to use in automobiles as verified through extensive third-party testing, including crash testing conducted by automotive OEMs.
