Green light for HFO1234yf from US environment authority

The US Environmental Protection Agency has given official final approval to HFO1234yf for use in new cars and light trucks, marking another step in the commercial development of the refrigerant.

The EPA’s approval is based on the gas being deemed as having 99.7% less global warming potential’ than R134a, which it is aimed at replacing.

“This new chemical helps fight climate change and ozone depletion,” said Gina McCarthy, assistant administrator for EPA’s Office of Air and Radiation. “It is homegrown innovative solutions like this that save lives and strengthen our economy.”

The Agency added “EPA’s recent standards for reducing greenhouse gas emissions from light-duty motor vehicles provide an opportunity for automakers to receive credit for adopting a chemical with less climate impact as a cost-effective way to meet the new standards. Using HFO-1234yf is one option available to automakers.”
