Keolis CEO Abdellah Chajai emphasized that encouraging rail travel is just the beginning. He said deeper action is vital to meet Massachusetts’ climate goals, and this project marks a significant step.

MBTA General Manager Phillip Eng welcomed the partnership and said the agency is focused on long-term environmental resilience. He noted that early feedback shows stable train performance with the new fuel.

Performance and Goals of the Renewable Diesel Pilot

So far, Keolis reports no drop in train efficiency under the renewable diesel pilot. The trial phase will help determine how widely the fuel can be deployed across the commuter rail system.

Both agencies see the project as a way to align with Massachusetts’ carbon-reduction targets. They expect the pilot to guide future investment in sustainable transportation options.

Renewable Diesel Pilot Supports Broader Sustainability Vision

Keolis Commuter Services has operated the MBTA Commuter Rail—the sixth largest in North America—for over a decade. Based in Boston, it is part of the Keolis Group, active in 13 countries.

This renewable diesel pilot reflects a joint commitment to sustainability, innovation, and clean public transit. The results may shape the future of eco-friendly rail travel in the region.
