This bill establishes a federal grant program to fund green transportation infrastructure projects that reduce greenhouse gas emissions and improve public transportation. The program would provide competitive grants to states, local governments, transit agencies, tribal nations, and other eligible entities for projects like electric bus systems, rail transit, charging stations, e-bike systems, and port improvements powered by clean energy. Recipients must commit to workforce development training, comply with prevailing wage requirements starting at $17 per hour, use renewable energy sources, and meet strict labor standards including paid family leave and fair scheduling practices. The bill prioritizes funding for disadvantaged communities, rural areas, and projects that serve low-income populations, requiring that at least 40 percent of annual funding go to these underserved areas. The legislation authorizes $50 billion annually for fiscal years 2025 through 2034, with funds remaining available through 2045, and includes provisions to strengthen prevailing wage protections and expand eligibility for transit projects. The bill also prohibits discrimination based on race, color, religion, national origin, sex, age, or disability in programs receiving these funds.
