EU affirms refrigerant is safe, Daimler still disagrees

R1234yf, the refrigerant jointly developed by Honeywell and Dupont that is being phased in as a replacement for R134a in Europe, is safe. So says a panel of scientists from the Joint Research Council, researching the refrigerant at the request of the European Commission. German automaker Daimler, though, disagrees with the finding, saying R1234yf can be toxic to humans when burned, according to Automotive News.

Automakers rushing to new HVAC refrigerant for EPA fuel economy credits

We don't have any new supercars to show you today. No new Teslas or SUVs. No new engines or technologies. No mergers, acquisitions or big hires. What we have to tell you about is the coolant automakers are putting into their vehicles. Which may not sound so exciting, but it could mean a big difference for automakers – and for the environment.

Daimler to resume French sales per court ruling

France's highest administrative court said yesterday that authorities must resume registering Daimler vehicles, which were formally banned in late July, Automotive News reports, even though they are still equipped with R134a air-conditioning refrigerant.

German motor authority issues report on contested refrigerant, everyone claims victory

On this episode of As the A/C Refrigerant Turns, the KBA, Germany's motor authority, has released its findings on the refrigerant r1234yf. The joint venture of Honeywell and Dupont, r1234yf has pitted Daimler against France and Germany against the EU; Daimler refused to use the new refrigerant, saying it's more dangerous to occupants in a crash, so France refused to register Mercedes-Be

More EU states may block Daimler cars as refrigerant battle heats up

The last time we checked in on the battle of refrigerants, France had enacted a registration ban on some Mercedes-Benz vehicles because their air-conditioning systems were loaded with R134a, which was found to be harmful to the environment by EU tests. Now, other EU states are considering banning the substance, according to Automotive News, as they push for a new refrigera

Safety outweighs emissions benefits of new A/C refrigerant for BMW

BMW has joined Daimler and, potentially, Audi in quitting an automotive industry research program studying a proposed new air conditioning refrigerant, the simply named HFO-1234yf. BMW disagrees with the test methods being used. "We do not want to say the test results are wrong, but we are not convinced the methods applied are sufficient to achieve a definitive conclusion that guarantees our high safety stan

VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of tes

HFO-1234yf: Get used to hearing it

What the heck is HFO-1234yf? That's the name of a new refrigerant that's reportedly 350-times less damaging to the atmosphere than the current HFC-134a (or 1,1,1,2-Tetrafluoroethane, if you prefer). You may recall that today's refrigerant was actually put into widespread use back in the early 1990s as a replacement for the long-running R12 that was found to be collecting in and damaging our delicate ozone layer.

Automakers work on sustainable air conditioning

It wasn't all that long ago that the auto industry was under fire for its use of ozone-depleting chemicals in its air conditioning systems. To curb those fears, the older R-12 refrigerant was replaced with R-134a refrigerant. Interestingly enough, CO2, long associated with harmful automobile emissions, is being touted as a desirable natural replacement for the chemical s
