  • Foam Policy in the United States Evelyn Swain U.S. Environmental Protection Agency UNEP Workshop on Low-GWP Replacements for Asia's Foam Industry Seoul, Republic of Korea 6-7 May 2010
  • Overview • U.S. EPA’s Significant New Alternatives Policy Program (SNAP) • U.S. HCFC Foams Regulations • U.S. Transition to Low-GWP Alternative Foam Blowing Agents
  • SNAP Background • Why was SNAP created? – Part of the U.S. response to the Montreal Protocol – Domestic Clean Air Act directs U.S. EPA to evaluate and list substitutes for ODSs that reduce overall risk to human health and the environment • What does SNAP cover? – Covers 8 industrial sectors that used ozone depleting substances: • Refrigeration and air conditioning, foam blowing, cleaning solvents, fire suppression, aerosols, adhesives coatings and inks, sterilants, and tobacco expansion • What does SNAP do? – Provides menu of substitutes for ozone-depleting substances – Lists acceptable and unacceptable substitutes for ODS – Does not require substitutes to be risk-free; instead identifies substitutes that reduce environmental or health risks View slide
  • SNAP Background • What Does SNAP Consider? – Ozone Depletion Potential (ODP) – Global Warming Potential (GWP) – Toxicity – Flammability – Other Environmental Impacts • SNAP Achievements – Health/Safety and Environmental Benefits – Over 450 substitutes reviewed – Provided industry with trustworthy information to assist in transition View slide
  • Low-GWP Foam Options • Low-GWP HCFC Alternative Options Do Exist for Foams! • SNAP Approved Low-GWP Alternatives: – Water – CO2 – HFO-1234ze(E) – Hydrocarbons – Methyl Formate
  • What Alternative to Choose? • Non HFC, low-GWP – alternatives are available, but must consider flammability and insulation efficiency • HFOs – may be good options where low flammability and insulation efficiency are important • HCs – may be good options where low flammability is not a concern • CO2 and Water – may be good options where insulation efficiency is not a concern
  • U.S. HCFC Foam Regulations • Nonessential Products Ban (1994) – Banned foam products that contain or are manufactured with HCFCs, but provided exemptions for insulating foams • HCFC-141b Ban (2003) – Limited to manufacture of foam • HCFC-22 & HCFC-142b Ban (2008) – Banned the use of HCFC-22, HCFC-142b, and blends thereof in commercial refrigeration, sandwich panels, slabstock, and other "pour foam" applications – Exemption for marine applications until 2009
  • U.S. HCFC Foam Regulations • HCFC Allocation Rule (2010) – Allows production & import of HCFC-22 and HCFC-142b ONLY for servicing existing equipment – All remaining HCFC foam blowing in the U.S. prohibited beginning Jan 1, 2010

  • Extra Slides
  • U.S., Canada, and Mexico Propose Phasing Down HFCs via Montreal Protocol • Amendment proposal submitted 4/29/10 to be considered by 196 countries this year • Phasedown not phaseout – Stepwise reductions – 15% plateau by 2034/2044 • Covers 20 HFCs, including 2 HFOs • Limits by-product emissions of HFC-23 • Supports overall global efforts to reduce GHGs – Cumulative benefits ~3,100 MMTCO2 eq through 2020; ~88,000 MMTCO2 eq through 2050 • equals removing 59 million passenger cars each year through 2020; 420 million through 2050
  • North American Proposed Amendment Global HFC Phasedown Schedule 100% 90% 90% 90% Non-A5 Reduction Steps 80% 80% 80% A5 Reduction Steps Cap - Percent of Baseline 70% 70% 70% 60% 50% 50% 50% 40% 30% 30% 30% 20% 15% 15% 10% 0% 2010 2015 2020 2025 2030 2035 2040 2045 2050 Years
  • Potential U.S. Greenhouse Gases Legislation • House of Representatives passed HR 2454, American Clean Energy Security Act – Similar bills being considered in Senate • Comprehensive approach to U.S. GHG emitting sectors; creates overall cap/trade • HFCs treated separately; added to ODS framework – Production and consumption allocated with annual reductions • Uses direct allocation and auction – “Phasedown” not phaseout: plateaus 15% of baseline • Complementary measures similar to ODS program: SNAP, Labeling, Refrigerant Recovery, Products Ban
