Volkswagen to use CO2 as refrigerant for future air conditioning systems

Green Car Congress

While last year it appeared that the auto industry as a whole would shift to R-1234yf, in September 2012, Daimler said that internal testing had identified safety (flammability) issues under certain conditions, and that it would not use R-1234yf in its products. BMW and Volkswagen followed suit. transition to a new refrigerant is not easy.
