MORRIS TOWNSHIP, New Jersey, April 6, 2011 - Honeywell (NYSE: HON) announced today that its new low-global-warming
refrigerant for use in automobile air conditioning systems has received final
approval from the U.S. Environmental Protection Agency.

The approval allows the refrigerant, HFO-1234yf, to be used in new cars
in the U.S. HFO-1234yf has a global-warming-potential (GWP) that is 99.7
percent less than HFC-134a, the refrigerant currently used in most car air
conditioning systems. The EPA granted the approval under its Significant New
Alternatives Policy (SNAP) program.

"This is a significant step toward global adoption of this new
refrigerant, which provides automakers with a near drop-in replacement for
today's refrigerant while helping them meet new regulatory standards," said
Terrence Hahn, vice president and general manager for Honeywell Fluorine

The EPA and U.S. Department of Transportation last year adopted new
standards for reducing greenhouse gas emissions from light-duty motor
vehicles. Vehicle manufacturers can receive credit toward the standards for
adopting refrigerants with less climate impact, such as HFO-1234yf.

"This new chemical helps fight climate change and ozone depletion," Gina
, assistant administrator for EPA's Office of Air and Radiation, said
in a press release. "It is homegrown innovative solutions like this that save
lives and strengthen our economy."

In addition to the new U.S. standards, the European Union has adopted the
Mobile Air Conditioning Directive, which requires new vehicle models starting
in 2011 to use a refrigerant with a GWP below 150. By 2017, all new
automobiles sold in Europe will be required to use a low-GWP refrigerant.

HFO-1234yf has undergone extensive testing for safety and efficacy by
independent testing groups such as the SAE International Cooperative Research
Program, in which leading automakers participate.

The SAE testing found the product offers environmental performance
superior to carbon dioxide, an alternative refrigerant, while having "the
lowest risk for use in mobile air conditioning systems in meeting
environmental and consumer needs."

According to industry estimates, there are more than 400 million cars
with air conditioning systems globally, with each system using between
one-half and one kilogram of refrigerant. Air conditioning systems using
HFO-1234yf are more energy efficient than carbon dioxide-based air
conditioning systems, particularly at high ambient temperature conditions.

blowing agents, solvents, aerosols and other materials for other applications
