Climat imate Act ction Pl ion Plan: an: HFC HFCs

 Continue international diplomacy

 Lead negotiations under the Montreal Protocol to phase down HFCs  Global phase down could reduce over 90 gigatons of CO2eq by

2050, equal to roughly two years worth of current global GHG emissions

 Work with partners in the Climate and Clean Air Coalition to Reduce Short-

Lived Climate Pollutants to promote climate-friendly alternatives to high- GWP HFCs, address technical standards, and reduce emissions from HFC use  Address HFCs through domestic actions

 Use existing Clean Air Act authority of Significant New Alternatives Policy

(SNAP) Program to approve climate-friendly chemicals, prohibit some uses of most harmful

Provide federal leadership by purchasing cleaner

alternatives to HFCs whenever feasible and by transitioning to equipment using safe, more sustainable alternatives

Acceptable - those that reduce overall risk to human health & environment
Acceptable with use restrictions - if needed to ensure safe use
Unacceptable

Evaluates alternatives & lists alternatives as:

Aerosols; Foams; Refrigeration and A/C; Solvents; Fire

Suppression; Adhesives, Coatings, Inks, etc.

Sectors include:

Ozone-Depletion Potential
Global Warming Potential

SNAP NAP A Acti tions ns 201 014-2015

 Issued two acceptability

notices adding alternatives

 Issued new rule adding

five low-GWP flammable refrigerants with use conditions

 Published Status Change

Rule prohibiting certain HFCs in certain end-uses

 HFC Emissions Avoided: 54-

64 MMTCO2eq in 2025

Near term changes can provide both near and long term benefits

Some me Key Pr Principl ples Guid s Guidin ing O g Our ur Thinki king

 SNAP rules will continue to consider individual end-uses  No across the board GWP cut offs  No prohibition on HFCs as a whole, or in any one sector  New HFCs or HFC blends may be listed if risk not greater

than other available substitutes

 Recognition that timing is a critical dimension and that each

end use has unique considerations

 Status change actions will be issued through notice and

comment rulemaking

lder M

r Meeting ng

 EPA considering proposed rule that could include:  Listing acceptable alternatives with use conditions

 Refrigeration & air conditioning end-uses for flammable refrigerants; Fire

suppression: e.g., streaming agent for aviation

 Listing of unacceptable alternatives

 Certain HC and HC blends for stationary AC retrofits and MVAC systems

 Change of listing status from acceptable to unacceptable

 EPA considering later transition dates than in July 20th final rule  End-uses based on stakeholder comments, EPA analysis

 Refrigeration and A/C  Rigid PU spray foam  Fire suppression: e.g., PFCs, SF6, HFC-23

SLIDE 10

Ne Next xt S Steps eps

 Continue to expand SNAP acceptable list  Continue to work with stakeholders

 E.g., Food Cold Chain Workshop in Montreal (held November 21st)  Sector workshops and Stakeholder meetings

 Develop next SNAP Notice for acceptable listings  Develop next SNAP Rule to include alternatives that are:

 Acceptable with use conditions  Unacceptable  Change of status

 EPA considering a proposed rule that may consider:

 Listing of 2-BTP as acceptable in certain applications  Change of listing status from acceptable to unacceptable for:

 PFCs (C3F8 and C4F10) in fire suppression total flooding uses  PFC (C6F14) in fire suppression streaming uses

 Request for comments and updated information on total flooding

uses of SF6 and HFC-23

 Comments on July SNAP final rule, recent petitions suggested

EPA also consider fire suppression applications

 Seeking stakeholder input pre-proposal given interest in

applications

 What specific end-uses and applications need additional low-GWP

alternatives?

 Are additional submissions anticipated for fire protection applications

(e.g., new chemicals, new blends, existing chemicals for new applications, new processes or technologies)?

 Under SNAP

, a potential substitute is often submitted for review for more than one use in a particular sector. EPA reviews substitutes on an end-use by end-use (or end-use category) basis. Is it helpful for EPA to move forward with listings in particular end-uses where we have made a determination recognizing we may still be reviewing other end-uses?
