Clean Car Options for the 21st Century

As society seeks to reduce greenhouse gases (GHGs) to 80% below 1990 levels to avert the worst consequences of global climate change, we must reduce GHGs from motor vehicles, which accounted for more than 37% of all US GHG emissions. This presentation explores the benefits of various alternative vehicles for reducing GHG emissions, local air pollution and oil consumption.  Alternatives include hybrid electric vehicles (HEVs), plug-in hybrids (PHEVs), battery electric vehicles (BEVs) and hydrogen-powered fuel cell electric vehicles (FCEVs).  Detailed computer simulations show that only FCEVs can achieve our goal of cutting GHGs to 80% below 1990 levels.
