European Commission's Top Scientific Body Concludes That Honeywell's Low-Global-Warming Refrigerant Is Safe For Use In Automobiles

MORRIS TOWNSHIP, NJ--March 7, 2014: Honeywell announced today that the European Commission's top scientific and technical body has concluded that Honeywell's new low-global-warming-potential mobile air conditioning refrigerant, HFO-1234yf, is safe for use in automobiles, marking the final word in a thorough and inclusive evaluation process.

"A scientific review of the research regarding the safety aspects of the use of refrigerant R1234yf in Mobile Air Conditioning (MAC) systems, published today by the European Commission, concludes that there is no evidence of a serious risk in the use of this refrigerant in MAC systems under normal and foreseeable conditions of use," the European Commission said in statement today (European Commission) following an extensive evaluation by the Commission's Joint Research Centre (JRC). "The review reinforces the conclusions by the German market surveillance authorities, the KBA (Kraftfahrt Bundesamt), which stated that there is no sufficient supporting evidence of a serious risk that would entail the intervention of the authorities."

JRC today issued a 17-page report (Automotive Environment) supporting its conclusions after a three-month evaluation during which it thoroughly reviewed the extensive testing done by a range of leading automakers as well as the world's foremost automotive engineering body, SAE International, and independent test agencies.

The JRC provides independent scientific and technical advice to the European Commission to broadly support policy-setting activities. It oversees seven scientific institutes across Europe with a wide range of laboratories and research capabilities.

"The JRC's independent and unimpeachable report leaves no doubt that HFO-1234yf is safe for automotive applications," said Ken Gayer, vice president and general manager for Honeywell Fluorine Products. "We continue to see strong adoption by global automakers of this new refrigerant as they work to meet new environmental regulation, especially in Europe, and are investing in production capacity to ensure adequate supply."

HFO-1234yf, a highly efficient, safe and effective replacement for the current automotive air conditioning refrigerant, HFC-134a, is already widely used by the auto industry. There are more than 500,000 automobiles safely using HFO-1234yf on the road today, and by the end of 2014 that number is expected to grow to more than 2 million. Third-party data shows that HFO-1234yf's widespread adoption globally would have the greenhouse gas equivalent of permanently removing more than 30 million cars from the road worldwide, or about 3 percent of the total global fleet.

HFO-1234yf is being adopted by automakers in part to meet the European Union's Mobile Air Conditioning (MAC) Directive, which aims to reduce the greenhouse gas emissions of air-conditioning systems in passenger cars and light commercial vehicles. As reconfirmed last month by the Intergovernmental Panel on Climate Change (IPCC), HFO-1234yf has a global warming potential of less than 1, which is even lower than that of carbon dioxide. This GWP is 99.9 percent lower than that of HFC-134a with a GWP of 1,300, which makes it an especially potent greenhouse gas. The JRC began its extensive evaluation of the extensive testing already conducted on HFO-1234yf in October 2013 at the request of The Directorate General for Enterprise to conclusively determine the safety of the refrigerant.

Daimler in late 2012 had raised questions about the refrigerant's safety due to its mild flammability. Last year, SAE International, the world's leading automotive engineering organization, which comprises engineers from the world's leading automotive manufacturers, concluded that the refrigerant was safe after completing an expanded and extensive evaluation. Those conclusions were backed by 10 global automakers who took part in the SAE Cooperative Research Project, including Chrysler/Fiat, Ford, General Motors, Honda, Hyundai, Jaguar Land Rover, Mazda, PSA, Renault and Toyota. The SAE report called Daimler's testing of the product to be "unrealistic."

SAE representatives as well as experts from several global car manufacturers also presented at JRC meetings, and the JRC reviewed testing and evaluations from multiple SAE Cooperative Research Programs as well as more recent testing by the KBA. The KBA's testing demonstrated that using HFO-1234yf creates no serious risks, and as a result it did not pursue action under Germany's Product Safety Act.

SAE International, formerly known as the Society of Automotive Engineers, is an independent, global association of more than 133,000 engineers and related technical experts in the aerospace, automotive and commercial vehicle industries.
