DuPont backs EPA’s proposed HFC reduction

Thierry Vanlancker, president of DuPont Chemicals & Fluoroproducts, has given his support to the proposed rulemaking by the U.S. Environmental Protection Agency (EPA) on HFC reduction.

In a statement he said: “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.

DuPont believes that the proven model of the Montreal Protocol is the most effective tool to reduce the use of high GWP 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.”

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.
