MBTA Tests Renewable Fuel to Cut Rail Emissions

MBTA and Keolis have launched a pilot program using renewable fuel at the Newburyport facility to reduce emissions and test cleaner alternatives in commuter rail operations. This is reported by the railway transport news portal Railway Supply.

The initiative introduces hydrotreated vegetable oil, a renewable fuel expected to lower CO2 emissions by over 70% compared to fossil diesel, according to Keolis CEO Abdellah Chajai.

So far, locomotives have shown stable and efficient performance while operating on the renewable blend. Keolis engineers are tracking engine output and fuel behavior to assess long-term viability.

At the end of the test, MBTA and Keolis will evaluate the results and determine whether to expand the program across the entire commuter rail system.

Renewable Fuel Offers Promising Emission Cuts

Chajai stated the switch to renewable fuel supports MBTA’s climate goals while maintaining service quality. He emphasized this trial could serve as a scalable model for clean transportation.

MBTA General Manager Phillip Eng noted the test aligns with other sustainability initiatives in the agency’s T service and reflects a commitment to greener transit solutions.

Next Steps in Renewable Fuel Adoption

If successful, the program may expand beyond Newburyport, potentially transforming how MBTA powers its fleet. The test marks a shift toward sustainable infrastructure investment in Massachusetts.

Public agencies nationwide are also exploring similar options as regulatory pressure and environmental awareness grow. Renewable alternatives continue to gain traction in public transit.
