About the Clearinghouse

The Transportation and Climate Change Clearinghouse aims to serve as a one-stop source of information for the transportation community on transportation and climate change issues. It is intended for use by the transportation community—from all levels of government, to private industry and non-profits, and provides a forum to share information, learn about new research, and understand practices and approaches that are being used to address the linkages between transportation and climate change.

The Transportation and Climate Change Clearinghouse was funded jointly through the National Cooperative Highway Research Program and the U.S. Department of Transportation's Center for Climate Change and Environmental Forecasting. The U.S. Department of Transportation's Research and Innovative Technology Administration maintains this website.
