§175 — Title 23 Highways | U.S. Code

Summary

The Secretary must create a carbon reduction program to cut carbon dioxide from on-road vehicles in each State. Metropolitan planning organization: the local planning group for urban areas. Urbanized area: a populated area as defined in section 134(b). Transportation management area: a large metro area designated under section 134(k)(1). States can use money from section 104(b)(7) for many projects that lower transportation emissions. Examples include traffic management and smart tech, public transit, walking and biking trails, congestion pricing and demand-management programs, freight improvements, electric vehicle and other alternative-fuel stations, zero-emission construction equipment, diesel retrofits, energy-efficient lighting and traffic devices, port electrification, and developing the State’s carbon reduction strategy. A State may also use funds for certain other projects if the Secretary certifies the State has cut emissions per person and per unit of economic output. Each State must make a carbon reduction strategy within 2 years after the Surface Transportation Reauthorization Act of 2021 was enacted, working with any metropolitan planning organizations. The plan must list ways and projects to cut emissions, encourage alternatives to single-occupant trips, favor lower-emission travel and construction methods, be appropriate for the State’s population patterns, and can measure lifecycle emissions of materials if the State chooses. The plan must be updated at least every 4 years. The Secretary will review a plan within 90 days of a State’s submission, certify it or deny it and say what must be fixed, and provide technical help on request. Each year 65% of a State’s 104(b)(7) funds must be used across areas divided by population size (over 200,000; 50,000–200,000; 5,000–49,999; under 5,000) in proportion to population, with the rest usable anywhere. States must coordinate with local planning groups before spending in urban or rural areas. For fiscal years 2022–2026, States that must obligate funds in areas with 50,000+ people must also make available a calculated amount of obligation authority for those areas. Federal cost share follows section 120, and projects under this program are treated as Federal-aid highway projects.

(a)In this section:

(2)The term “transportation emissions” means carbon dioxide emissions from on-road highway sources of those emissions within a State.

(3)The term “transportation management area” means a transportation management area identified or designated by the Secretary under section 134(k)(1).

(b)The Secretary shall establish a carbon reduction program to reduce transportation emissions.

(D)a project described in section 503(c)(4)(E) for advanced transportation and congestion management technologies;

(E)a project for the deployment of infrastructure-based intelligent transportation systems capital improvements and the installation of vehicle-to-infrastructure communications equipment, including retrofitting dedicated short-range communications (DSRC) technology deployed as part of an existing pilot program to cellular vehicle-to-everything (C–V2X) technology;

(F)a project to replace street lighting and traffic control devices with energy-efficient alternatives;

(G)the development of a carbon reduction strategy in accordance with subsection (d);

(H)a project or strategy that is designed to support congestion pricing, shifting transportation demand to nonpeak hours or other transportation modes, increasing vehicle occupancy rates, or otherwise reducing demand for roads, including electronic toll collection, and travel demand management strategies and programs;

(I)efforts to reduce the environmental and community impacts of freight movement;

(J)a project to support deployment of alternative fuel vehicles, including—

(i)the acquisition, installation, or operation of publicly accessible electric vehicle charging infrastructure or hydrogen, natural gas, or propane vehicle fueling infrastructure; and

(ii)the purchase or lease of zero-emission construction equipment and vehicles, including the acquisition, construction, or leasing of required supporting facilities;

(K)a project described in section 149(b)(8) for a diesel engine retrofit;

(L)a project described in section 149(b)(5) that does not result in the construction of new capacity; and

(M)a project that reduces transportation emissions at port facilities, including through the advancement of port electrification.

(2)In addition to the eligible projects under paragraph (1), a State may use funds apportioned under section 104(b)(7) for a project eligible under section 133(b) if the Secretary certifies that the State has demonstrated a reduction in transportation emissions—

(A)as estimated on a per capita basis; and

(B)as estimated on a per unit of economic output basis.

(d)(1)Not later than 2 years after the date of enactment of the Surface Transportation Reauthorization Act of 2021, a State, in consultation with any metropolitan planning organization designated within the State, shall develop a carbon reduction strategy in accordance with this subsection.

(A)support efforts to reduce transportation emissions;

(B)identify projects and strategies to reduce transportation emissions, which may include projects and strategies for safe, reliable, and cost-effective options—
