The study found HFO 1234yf 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 HFO 1234yf at 4, which is still a 99.7 percent improvement over HFC 134a, the manufacturer noted.
If this is indeed the case, is it safe for the average vehicle owner to just vent it to atmosphere?
Or is there some other EHS gotcha that needs to be kept in mind?
