Low-Global-Warming-Potential Alternative Meets New European Environmental Regulations.

Honeywell and DuPont Announce Joint Venture to Manufacture New Automotive Refrigerant
May 20, 2010 - Honeywell (NYSE: HON) and DuPont (NYSE: DD) today announced a manufacturing joint venture to produce a new refrigerant for use in automotive air conditioning systems. The new refrigerant has 99.7 percent lower global warming potential (GWP) than the current refrigerant.

Under the agreement, DuPont and Honeywell will share financial and technological resources with the intent to jointly design, construct and operate a world-scale manufacturing facility for the new refrigerant, known as HFO-1234yf. The product meets European Union regulatory requirements for lower GWP refrigerants for automobile air conditioning systems. DuPont and Honeywell developed the product jointly but will market and sell it separately.

"Through this manufacturing partnership, Honeywell and DuPont will deliver to the automobile industry this environmentally preferable solution that meets both operational and regulatory requirements. Globally, consumers will benefit from this new technology, which reduces greenhouse gas emissions," said Terrence Hahn, vice president and general manager for Honeywell's Fluorine Products business. "This complements Honeywell's significant energy efficiency and environmental solutions portfolio, which is positioned to deliver efficiency advantages to a wide array of industries while benefiting the environment."

"The new refrigerant enables the automotive industry to reduce the environmental footprint of vehicles at significantly lower cost than alternatives," said Gary W. Spitzer, president - DuPont Chemicals & Fluoroproducts. "By working together with Honeywell, DuPont is confident we'll have the winning combination to enable the industry to realize environmental benefits sooner. DuPont's role in the introduction of HFO-1234yf is another great example of the innovation DuPont has brought to the automotive industry for nearly a century."

This venture follows an earlier joint development agreement under which the two companies developed the product. The joint venture announced today is designed to provide DuPont and Honeywell with a world-class source of supply to meet the growing demand faster than would be possible through either company's individual efforts.

Today's automotive air conditioners use hydrofluorocarbon HFC-134a, which has a GWP of 1430. The European Union's Mobile Air Conditioning Directive requires that, starting in 2011, all new vehicle models use a refrigerant with a GWP below 150, and by 2017, all new automobiles sold in Europe will be required to use a low-GWP refrigerant. The new refrigerant, developed by DuPont and Honeywell, has a GWP of 4, which is 97 percent less GWP than the new regulation requires.

Prior to construction of a world-scale plant, the joint venture will begin supplying the refrigerant in the fourth quarter of 2011 in time to meet the European Union regulatory requirement.

Honeywell and DuPont introduced HFO-1234yf to the automotive industry in 2007, and since then, it 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, developed by DuPont and Honeywell, are more energy efficient than carbon dioxide-based air conditioning systems, particularly at high ambient temperature conditions.
