The Global Warming Potential of HFO-1234yf is 4 compared to 1400 for R134a. Manufacturing of the R134a will eventually cease just like R-12, and once that happens, only what is recovered from systems will be available....just like R-12.
We can thank the European Parliment for the change, they decided that no cars maufactured in Europe after Jan 1, 2011 would use R134a, and the SAE Interior Climate Control Committee decided to follow suit (most likely with some pressure from the EU) so that European car manufacturer's would not have to run 2 different systems (HFO for Europe and R134 for US).
Also, R134a is a "blend" while HFO is a single component refrigerant.
Welcome to the "greening" of the auto industry.
