The trucks are operating in the Port of Los Angeles and Port of Long Beach.
The renewable natural gas trucks are equipped with the ultralow-NOx Cummins Westport (CWI) ISX12N engine and fueled with Clean Energy Fuels Corp.
The development follows the 2017 adoption of the Clean Air Action Plan by the San Pedro Bay Ports in a bid to reduce carbon emissions and combat climate change.
The Plan has paved way for the California Air Resources Board (CARB) to approve a $533 million plan for clean transportation investments.
The investments are being issued through the Clean Vehicle Rebate and Hybrid and Zero-Emission Truck and Bus Voucher Incentive projects.
To date, 40% of greenhouse gas emissions come from the transport industry in California.
Mary Nichols, CARB Chair, said: “California is backing up our tough vehicle regulations with money to help individuals and businesses access the newest, cleanest technology.

“It will take a mix of incentives and mandates to meet public health and climate goals. We need to speed up the pace of change, and these investments play an important role in assuring the state remains home to the nation’s largest fleet of advanced vehicles.”
“Switching to trucks fueled with RNG is vital to improving air quality and fighting climate change in our country’s largest port complex,” said Greg Roche, vice president, Clean Energy. “This is a prime example of fleets taking action that immediately decreases the environmental impact of their operations. Switching to cleaner fuel and engine technologies is reducing air and climate pollution and helping the region achieve its clean air goals.”
Redeem is the first commercially available RNG vehicle fuel.
