  1. The Benefits of Full Fuel Cycle Emissions ModelingA Public Interest Perspective Presented by Roland J. Hwang Transportation Program Director at the U.S. EPA Workshop on Alternative Fuel Modeling Louisville, Kentucky May 26, 1999 2397 Shattuck Avenue, Suite 203 Berkeley, CA 94704 510/843-1872, www.ucsusa.org

  2. Purpose of Full Fuel Cycle Model • Capture full benefits of alternative fuel and advanced technology (high fuel economy) vehicles • Immediate need to guide evaluation of AFV/ATV in development of integrated, least cost solutions to air quality, air toxics, and climate change challenges

  3. Policy Uses • “Soft” policy guidance, examples • Fleet and individual purchasers • State and federal R&D funding • Inform policy efforts to integrate AQ, GHG, and air toxic goals • “Hard” policy uses, examples • SIP credits • Early action GHG credits

  4. Pollutants of Interest • Criteria Pollutants • Upstream impacts • Greenhouse Gases • Need to inform pre-Kyoto actions • e.g., identification of multi-benefit policies, early action credit generation • Air Toxics • Motor vehicles primary contributors

  5. Fuels and Technologies of Interest • Advanced Technology Vehicles (ATVs) • Gasoline hybrid electric, high fuel economy • Battery electric and fuel cell vehicles Gasoline additives, low volume blends • EtOH, climate change and air toxics • Alternative Fuel Vehicles (AFVs) • CNG for buses and heavy-duty trucks

  6. Key Recommendations • Upstream criteria pollutants • Adopt and enhance GREET • Air Toxics • In interim, EPA should develop stand alone module, analogous to PART5 • Greenhouse Gases • Need for “official” model to quantify credits and FFC GHG models relatively mature
