The safest refrigerant is CO2. Germany uses carbon dioxide refrigerant in domestic cars and refrigeration. But, I don't think they can export it to the US.
Germany switched away from Freon refrigerants because it's a potential health hazard.
R12 is relatively neutral in terms of pH. CO2 is not. I'd expect those systems to have less installation life and present all kinds of "odd" problems at the joints.
