Important studies of the well-to-wheels emissions of vehicles were released in 2007. Well-to-wheels analyses look at the emissions produced by vehicles and from making and transporting the fuel. As our energy and transportation industries converge, well-to-wheels analyses will give us the data we need to choose the best options for the planet. The speaker will give a summary of all accessible studies comparing the well-to-wheels emissions of conventional gasoline vehicles, hybrids, plug-in hybrids, battery electric vehicles, and hydrogen fuel-cell vehicles. The talk will update a presentation made at the 23rd international Electric Vehicle Symposium (EVS23) on December 4, 2007 in Anaheim, Calif. See the paper accepted for that meeting: See the PowerPoint slides from that presentation: The author began this overview as research for her book, Plug-in Hybrids: The Cars That Will Recharge America (New Society Publishers). More than 40 analyses suggest that plug-in hybrids reduce carbon dioxide by 37%-67% compared with conventional cars. Compared with hybrids, plug-in hybrids reduce carbon dioxide emissions by 15%-54% and battery electric vehicles reduce emissions by 25%-54%. Similar results are seen for air quality pollutants. Hydrogen fuel-cell vehicles use more energy and produce more greenhouse gas emissions than battery electric vehicles.
