New environment-friendly automobile air-conditioning refrigerant standardized for United States

A few years ahead in the future, switching on your car’s air-conditioner won’t be so much of an environmental hazard. Here’s why. The Environmental Protection Agency of the United States has just ticked a new refrigerant HFO-1234yf for use in vehicles with a global warming potential that is 99.7 percent less than the current chemical (HFC-134a) used. The refrigerant designed by Honeywell and DuPont will revolutionize the automotive industry and help keep commuters cool, without too much harm to the environment. A few years in the future from now, the new refrigerant, HFO-1234yf, will be a standard for U.S. automakers.

With this change brought about in automobile air-conditioning systems, cooling your car will be a breeze and a relief to the environment like never before.
