Transportation's Role in Reducing U.S. Greenhouse Gas Emissions ...

Transportation's Role in Reducing U.S. Greenhouse Gas Emissions: Volume 1
transportation. This AEO projection assumes an average annual growth in VMT
of 1.5 percent.
The AEO projections take into account existing government legislation and
regulations, but do not consider additional government policies, such as
subsequent increases in fuel economy standards. The projections shown here are
based on the AEO reference case from the April 2009 update, which includes the
anticipated effects of the American Recovery and Reinvestment Act (ARRA), and
the fuel economy and renewable standards included in the Energy Independence
and Security Act (EISA) of 2007.
With the new standard of 35.5 mpg for new vehicles by 2016, light-duty GHG
emissions would be approximately 4 percent lower in 2020, and 3 percent lower
in 2030, than the projections provided in this report.
