High-Speed Rail Project

California High-Speed Rail Authority


What does it fund?

Development of California’s high-speed rail system, the first high‑speed rail in the nation that will connect the megaregions of the state. When complete, it will run from San Francisco to the Los Angeles basin in under three hours at speeds capable of over 200 miles per hour, providing a clean alternative to driving or flying. Funded in part by California Climate Investments, the project is contributing to economic development and a cleaner environment, supporting jobs, and preserving agricultural and protected lands.

In operation, the significant capacity available to accommodate modal shift from driving and intrastate flights provides California with a unique transportation tool in its approach to a low carbon future. Estimated greenhouse gas (GHG) emissions reductions from the California High-Speed Rail project is 102 million metric tons of carbon dioxide equivalents (MTCO2e) over its first 50 years of operating life, as detailed in the 2021 California High-Speed Rail Sustainability Report.

The California High-Speed Rail Authority (Authority) has committed to and is delivering the greenest infrastructure project in the nation, both in construction and operations. The program received national recognition for its sustainability efforts when it received the Envision Platinum rating from the Institute for Sustainable Infrastructure. It is the highest‑level award from the institute and the first time a program of this geographic size and complexity has earned such an honor.

In keeping with its focus on advancing clean construction, the Authority requires contractors use only zero-emission vehicles for their project fleets in all future construction contracts. “As rail construction continues to ramp up, we need to keep driving our emissions down,” said Authority CEO Brian Kelly. “That’s why we’re looking for new ways to make our construction practices even greener.”

The Authority has also taken several steps to help offset the emissions from the rail’s construction:

  • Planted more than 7,100 urban trees since 2018. Urban and rural tree plantings combined are expected to sequester 143,000 MTCO2e over the trees’ life cycles

  • Sequestered or avoided an estimated 151,000 MTCO2e through conservation of more than 2,300 acres of natural habitat and 3,000 acres of agricultural land since January 2016  

  • Recycled more than 95 percent (196,906 tons) of all waste to date and sent less than 5 percent (9,651 tons) to landfills, avoiding more than 146,000 MTCO2e over the entire construction time frame.

How does this program provide benefits to priority populations?

At a time of economic distress for many due to COVID‑19, essential construction work continues, providing jobs for Californians. As of November 2021, the Authority has commissioned work from 653 small businesses, including 213 Certified Disadvantaged Business Enterprises, ensuring small businesses play a significant role in the program. Importantly, 155 of the small businesses working on the high-speed rail system are in disadvantaged communities. In the Central Valley, more than 6,000 construction jobs have been created to date across 119 miles of high‑speed rail construction, and approximately half of those workers live in disadvantaged communities.

From the beginning of the program through fiscal year 2020-21, 98 percent of project spending on planning and construction has taken place in California. This investment in the California economy has supported direct, indirect, and induced jobs, over half of which are located in the Central Valley. These economic impacts have already taken place and do not consider the many future benefits once operations commence and the program delivers greater accessibility and station-area connectivity, reduced highway congestion, and travel time savings.

Additional Background:

The High-Speed Rail Community Benefits Agreement (CBA) encourages a 30 percent small business participation goal and ensures that 30 percent of all project work hours are performed by National Targeted Workers, with at least 10 percent of those work hours be performed by Disadvantaged Workers. Targeted Workers include individuals that reside in low-income ZIP codes. A Disadvantaged Worker is a Targeted Worker with additional barriers to employment.

The CBA definitions of Targeted Worker and Disadvantaged Worker are not currently aligned with the designations of priority populations for the purposes of meeting the investment minimums in SB 535 or AB 1550. For this reason, these employment benefits are not currently accounted towards meeting investment minimums for benefits to priority populations, despite providing a direct and assured benefit to those targeted employees. CARB and Authority staff are actively working to account for priority population benefits.

Who is eligible for funds?
