Coll: The big news of course is the change away from R-134a as noted in the EPA (Environmental Protection Agency) meeting we had (recently) down in Dallas. It looks like that's going to happen.
There are equipment and tools coming out and more information being let out about the new refrigerant that's going to take over for R-134a.
Motor Age: Has a frontrunner been established?
Coll: There are two candidates: one is CO2, and the other is called HFO-1234yf. (However) there were some barriers to changing refrigerants. We're not seeing any higher prices. Of course, R-22 on the commercial side is going up (in price) significantly as that phase-out continues, but on the automotive side, I think what you may see is some reduction in purchase of equipment related to R-134a, (but) not a significant reduction because R-134a will be around for a long time.
Motor Age: There are also flammability issues with HFO-1234yf, correct?
Coll: That's correct. The flammability issues there depend on who you listen to. Everything will burn given enough heat. I believe flammability issues have been adequately addressed and will not pose any significant risk.
As we know, car manufacturers are extremely careful about that to the best of their abilities to make sure things are contained properly. There will be some new regulations related to it.
You well may not be able to buy HFO-1234yf at your local Wal-Mart like you can with R-134a. There will be new training and new certifications required, but as a substance itself, I would view it as a very low risk on the flammability scale, especially when compared to HFC-152a.
Motor Age: Is there a timetable set by the EPA on replacing R-134a?
Coll: The EPA has not yet set a timetable. However, the new Democratic administration has asked for a very immediate and thorough review of ways that we can reduce our carbon emissions, particularly through automotive and industrial areas. So, although no timetable has been put together, we think it's not long before one is put together.
