Transportation’s Role in Reducing U.S. Greenhouse Gas Emissions: Volume 2
• Section 4.0 – System Efficiency discusses a diverse set of strategies focused on ways
to optimize the use of the transportation network by improving the efficiency of
transportation operations. System efficiency strategies discussed in this report
include: Highway operations and management strategies, truck operations and
management strategies, improvements to the efficiency of rail and marine freight
systems, aviation operations practices, and improvements in materials and methods
that reduce GHG emissions generated during the construction and maintenance of
transportation infrastructure.
• Section 5.0 – Strategies to Carbon-Intensive Travel Activity discusses strategies to
reduce greenhouse gas emissions by influencing travelers’ activity patterns in order to
reduce total travel, shift travel to more efficient modes, or take other actions that
reduce energy use and GHG emissions associated with personal travel. Travel
behavior strategies discussed in this section include: Pricing, improvements to transit
and nonmotorized modes, land use and parking management strategies, commuter/
worksite trip reduction programs, and other public information programs.
The reader is directed to Volume 1 for an overview of transportation and climate change
in the U.S., and a discussion of the policy options that Congress may want to consider to
promote greenhouse gas reductions from this sector, based on the technical analysis
presented in this volume.
