" The move is generally regarded to have been effective: since the worldwide shift away from fluorocarbons, the ozone hole has not only stopped growing, it has actually contracted."
Looks like they still don't bother to check facts over there.
If you look at pictures of the hole in the 0-zone you cant tell that R-12 has been banned and that levels of R-12 in the upper atmosphere have been dropping for years.
"Although the product is classified slightly flammable by ASHRAE, several years of testing by SAE proved that the product could not be ignited under conditions normally experienced by a vehicle. In addition several independent authorities evaluated the safety of the product in vehicles and some of them concluded that it was as safe to use as R-134a, the product in use in cars today. In the atmosphere, HFO-1234yf degrades to trifluoroacetic acid, which is a mildly phytotoxic strong organic acid with no known degradation mechanism in water. In case of fire it can release highly corrosive and toxic hydrogen fluoride".
Aside from all that good news I say use CO2 so Honeywell wont get filthy rich off a patent created to solve a non problem.
