The US Department of Transportation is making available $800 million in funding under the Low Carbon Transportation Materials (LCTM) Program. Administered by the Federal Highway Administration (FHWA), LCTM will support the use of low-carbon materials and products used in transportation that reduce air pollution, specifically greenhouse gas emissions (GHG).

FHWA made $1.2 billion available under this program to state departments of transportation in March 2024 and is now opening funding up to other potential applicants such as cities, metropolitan planning organizations, tribal governments and other federal, state and local agencies that also carry out transportation activities.

The Low Carbon Transportation Materials Grants program is one of three new programs at FHWA created by the Inflation Reduction Act—the largest investment in climate action and clean energy in history. FHWA continues to closely collaborate with the Environmental Protection Agency and General Services Administration to implement related low carbon programs that were authorized in the Inflation Reduction Act.

The LCTM program makes $2 billion available under the Inflation Reduction Act for State Departments of Transportation, cities, Tribes, Metropolitan Planning Organizations, and other agencies to incorporate more materials that create less pollution, including steel, concrete (and cement), glass, and asphalt.

In addition to funding the use of cleaner construction materials that reduce pollution and carbon emissions for transportation projects, the program will provide resources for agencies to implement processes and coordinate with industry to quantify the emissions of construction materials. That information will allow substantially lower carbon materials to be identified by comparing emissions to established thresholds. Funding can also be used to develop specifications for low-embodied carbon materials that ensure adequate engineering performance for appropriate use on Federal-aid projects.
