Real Transportation Solutions for Greenhouse Gas Emissions Reductions. This report outlines AASHTO's recommended strategies to reduce greenhouse gas emissions from transportation - including: smarter travel: reduce the rate of growth in the number of vehicle miles traveled (VMT) in the United States; better cars: increase vehicle fuel efficiency; better fuels: shift to fuels that produce low or zero carbon dioxide emissions; optimize the system: improve the efficiency and operation of our roads.
Transportation Strategies for Reducing Green House Gas Emissions. This page from AASHTO's Real Solutions materials outlines a range of GHG reduction strategies supported by state DOTs.
Primer on Transportation and Global Climate Change, AASHTO (April 2008). AASHTO developed this primer as an introduction to the issue of climate change and its implications for transportation policy in the United States. Part I of this primer focuses on the causes and impacts of climate change, and Part II focuses on climate change and public policy. Part III focuses on trends in GHG emissions from road travel, while Part IV focuses on how to reach GHG emissions reduction goals.
