This is one of a series of reports produced as a result of the Transportation Energy Futures (TEF) project, a U.S. Department of Energy (DOE)-sponsored multi-agency project initiated to identify underexplored strategies for abating greenhouse gases (GHG) and reducing petroleum dependence related to transportation.


Government agencies at all levels are increasingly setting aggressive targets to reduce greenhouse gas (GHG) emissions and mitigate the potential impact of climate change. These targets can range up to an 80 percent reduction in emissions levels by the year 2050, compared to 1990 levels.
