Air conditioners in EVs may not be that dirty of a secret

Reports that the leaking of a certain type of air-conditioning fluid used in electric vehicles may help cause global warming may be a bit of hot air. The Union of Concerned Scientists (UCS) is addressing stories saying that HFC-134a, also known as R-134a, may nullify the benefits of driving electric because of its potential effect on the ozone. The UCS debunks those stories.

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

Just like the R-12 refrigerant that was phased out of cars in the 1990s, it appears R-134a is on its way out, as well, in favor of the more environmentally friendly R-1234yf. While R-134a definitely isn't as harmful to the ozone as R-12 was (which led it to be banned), the newer R-1234yf has a far lower global warming potential than the refrigerant currently used. This sounds good for the environment and all, but Jeffrey N. Ross
