`
`WARREN, Mich. – General Motors Co. will introduce a new greenhouse gas-friendly air-conditioning
`refrigerant in 2013 Chevrolet, Buick, GMC and Cadillac models in the U.S. that keeps vehicle interiors as
`cool as today while reducing heat-trapping gases in the atmosphere by more than 99 percent.
`
`The biggest benefit of the new refrigerant, (HFO-1234yf) supplied by Honeywell, is that it breaks down faster
`in the atmosphere than the refrigerant currently used (R-134a), On average, R-134a refrigerant has an
`atmospheric life of more than 13 years, giving it a global warming potential (GWP) of over 1,400.
`
`By comparison, the new refrigerant lingers in the atmosphere for just 11 days and has a GWP of only 4, a
`99.7 percent improvement. GWP is a value used to compare different greenhouse gases that trap heat in the
`atmosphere. The base measurement for GWP is relative to that of carbon dioxide (CO2).
`
`The U.S. Environmental Protection Agency awards regulatory credit for the improved environmental
`performance of the new refrigerant, which helps GM meet the overall requirements of the EPA’s new motor
`vehicle greenhouse gas regulations. The new regulation requires an overall 40 percent improvement in
`overall U.S. fleet average vehicle fuel economy by 2016. The use of HFO-1234yf will help GM vehicles
`significantly exceed its targets under the new regulations.
`
`“GM’s decision to adopt this new refrigerant is additional proof of our commitment to be on the forefront of
`green technologies that will keep our planet healthy for our children and grand-children,” said Mike Robinson,
`GM vice president of Environment, Energy and Safety Policy. “It’s not just about meeting regulatory
`requirements; it’s about environmental leadership and GM plans to lead in developing new technologies that
`will take the vehicle out of the environmental debate.”

`
`Said Terrence Hahn, vice president and general manager for Honeywell Fluorine Products: “We’re pleased
`that GM is taking the lead in choosing HFO-1234yf, a refrigerant that has a lower impact on global warming.
`This is another example of how Honeywell is developing innovative new environmental and energy-efficient
`solutions to meet our customers’ current and future needs.”

`"Unlike HFCs and CFCs which take generations to decompose, HFO-1234yf does not accumulate in the
`atmosphere creating long-term issues. A short atmospheric lifetime means less impact on the environment.
`HFO-1234yf is highly stable in the compressor system of an air conditioner, and, if it escapes, will not persist in
`the environment." Graphic courtesy of Honeywell.
