UN Climate body accepts GWP of R1234yf refrigerant is 'lower than CO2'

The UN’s Intergovernmental Panel on Climate Change has confirmed that the automotive HFO refrigerant R1234yf has a GWP of less than 1.0, making it lower than CO2

The UN’s Intergovernmental Panel on Climate Change has confirmed that the automotive HFO refrigerant R1234yf has a GWP of less than 1.0, making it lower than CO2.

“The IPCC report confirms that HFO-1234yf has a lower global warming potential than carbon dioxide,” said Ken Gayer, vice president and general manager of Honeywell Fluorine Products.

IPCC has accepted the findings of an independent, peer-reviewed paper, published last year and reported by RAC. The paper in volume 51 of Reviews of Geophysics was the first to calculate the GWPs of all fluorocarbon-based refrigerants using all available atmospheric data, taking into account local atmospheric patterns.

The study found R1234yf to have a GWP of less than 1. CO2 is considered the baseline with a GWP equal to 1. Earlier studies had calculated the GWP for R1234yf at 4.

Nearly half a million cars are now reported to be on the road today using R1234yf, and by the end of 2014, the number of vehicles is expected to exceed 2 million.
