TRB Webinar: Forecasting Zero Emission Vehicles Fleet Scenarios & Emissions Implications


How will future vehicle Zero Emission Vehicles (ZEV) fleet scenarios affect emissions of criteria pollutants, mobile source air toxics, and greenhouse gases? TRB conducted a webinar on Tuesday, June 30 that discussed research on future vehicle fleet scenarios’ effect on emissions. Presenters reviewed literature and modeling analysis on U.S. ZEV adoption. The work provides insights encouraging the adoption of ZEVs such as electric or fuel cell vehicles with implications for state departments of transportation and metropolitan planning organizations seeking to make policy decisions to advance penetration of ZEVs into the light-duty vehicle fleet. Presenters also discussed future research suggestions.

This webinar draws on research from NCHRP Web-Only Document 274: Zero Emission Vehicles: Forecasting Fleet Scenarios and their Emissions Implications.

The slides are available. Contact Reggie Gillum for a copy of the recorded webinar.

  2. Key findings from literature review, rationale for Market Acceptance of Advanced Automotive Technologies model, and future research suggestions: Adrienne Heller, WSP
  3. Guiding principles for development and selection of ZEV adoption analysis scenarios, modeled ZEV population increases, and implications of results: Garnet Erdakos, Sonoma Technology, Inc.
  4. Modeled ZEV population increases and emissions reductions: Shih Ying Chang (Changsy), Sonoma Technology, Inc.
  5. Question and answer session moderated by Zhenhong Lin, Oak Ridge National Laboratory

The first 90 minutes of the webinar will be for presentations and the final 30 minutes will be reserved for audience questions.

Learning Objectives

At the end of this webinar, participants will be able to:

  1. Identify different ZEV adoption models in the U.S.
  2. Discuss how different fleet scenarios will effect emissions

Professional Development Hour Information

Professional engineers (PEs) who register and attend the entire webinar as an individual will be awarded 2 Professional Development Hours (PDHs). TRB’s webinar program awards PDH credits only to the registered individual, and not to other members of a group that view the webinar together.
