Greenhouse Gas Mitigation & Energy
PDF files can be viewed with the Acrobat® Reader®
The transportation sector is the source of 29 percent of U.S. greenhouse gas (GHG) emissions. National commitments to reduce emissions 26-28 percent by 2025 and 80 percent or more by 2050, necessitate less energy use and a transition to alternative energy. FHWA is working with States and metropolitan areas to:
- Integrate GHG reduction analysis into transportation planning.
- Deploy infrastructure needed for low carbon fuels.
- Reduce GHG emissions in construction and maintenance practices.
- Improve system and travel efficiencies.
