DuPont Statement: EPA Proposed Rules Recognize Availability of Viable Low GWP Solutions

Wilmington, Del., July 15, 2014

DuPont has Invested Significantly in Offerings that Enable the Transition to Low GWP Alternatives

Thierry Vanlancker, president, DuPont Chemicals & Fluoroproducts, today made the following statements on proposed rulemaking by the U.S. Environmental Protection Agency (EPA):

"DuPont supports the EPA's direction in its proposed rulemaking to prohibit use of certain hydrofluorocarbons (HFCs) and HFC-containing blends. The proposal is to prohibit these products in several applications where there are viable alternatives that present lower overall risk and have much lower potential impact on the climate.

"The EPA proposal would be implemented under the Agency's Significant New Alternatives Policy (SNAP) program.  Under the proposed rule, the specified HFCs and HFC blends that were previously listed under the SNAP program as acceptable alternatives to ozone-depleting substances will be listed as unacceptable for some uses in new equipment or for retrofit in existing equipment.  The proposal includes refrigerants used in mobile air conditioning, stationary refrigeration, and some HFCs used in foam and aerosol applications. 

"DuPont has invested significantly in the introduction of an entire family of Opteon™ brand products based on hydrofluoro-olefin (HFO) technology, which offers extremely low global warming potential (GWP) and no ozone depletion potential (ODP).  We have introduced HFO-based products for mobile air conditioning and stationary refrigeration, and we are actively working to bring to market additional low GWP solutions for foams and other applications.  These solutions enable the transitions to lower GWP HFCs and HFOs that regulations increasingly require, while also offering excellent energy efficiency and meeting a range of other performance criteria.

"DuPont believes that the proven model of the Montreal Protocol is the most effective tool to reduce greenhouse gas emissions associated with the use of HFCs on a coordinated global basis. We support the proposed Montreal Protocol Amendment that would bring HFCs under the Protocol, and believe the EPA’s proposed rule is consistent with the goals of that amendment.

"The proposed changes also are consistent with regulatory activity in the European Union and Japan.  As a prelude to a Montreal Protocol Amendment, these policies take advantage of the effective low GWP solutions available in the market today.

"We look forward to reviewing the rule in detail, and will be particularly interested in appropriate timing for changes in SNAP status for various applications, taking into account current trends such as the European Union transition to low GWP refrigerants for all new vehicles by 2017, and reasonable transition times in segments such as foams.

"DuPont has been a leader in refrigerants and foams for nearly 85 years. HFOs represent the fourth generation of refrigerants, foams and related products introduced by DuPont, which pioneered the science on which much of modern refrigeration is based." 

DuPont (NYSE: DD) has been bringing world-class science and engineering to the global marketplace in the form of innovative products, materials, and services since 1802.  The company believes that by collaborating with customers, governments, NGOs, and thought leaders we can help find solutions to such global challenges as providing enough healthy food for people everywhere, decreasing dependence on fossil fuels, and protecting life and the environment.  For additional information about DuPont and its commitment to inclusive innovation, please visit
