13. ABSTRACT (Maximum 200 words)
This report assesses the potential of substitutes for gasoline to reduce emissions of carbon dioxide and other greenhouse gases
(GHGs) by automobiles and light-duty trucks. It estimates reductions in future GHG emissions under specific assumptions about
growth in light-duty vehicle travel and the replacement of gasoline by various other fuels, both in the near term (10 years) and
over the longer term (25 years). Under reasonable assumptions about the fraction of projected gasoline use that could be replaced
by another fuel within these time horizons, it concludes that the reduction in GHG emissions from most gasoline substitutes would
be modest. The report also assesses the cost-effectiveness of replacing gasoline with each of these fuels as a strategy for reducing
GHG emissions, and concludes that promoting alternative fuels would be a costly strategy for reducing emissions. Finally, the
study also briefly surveys other concerns that are likely to arise in making a transition from near-exclusive reliance on gasoline to
widespread production and use of any alternative fuel. These concerns include potential health and safety consequences,
developing the infrastructure required to support commercial-scale production and distribution of gasoline substitutes, and
producing adequate supplies of feedstocks required to refine certain fuels.
