Clean Diesel

The First Step to Sustainability

Before the new technologies of the Hydrogen, Electric, and Natural Gas Engines, the first step in transforming TTSI to a green fleet were clean diesel trucks.

Transportation Leader


Before clean diesel, there were old trucks with no emissions standards at all. Clean diesel trucks greatly improved emissions began clearing the air and opening doors for new, sustainable technologies.TTSI still employs clean diesel as a model of the "next-step" in ports that still run on old, dirty trucks.

Our First Sustainable Fleet


In 2008 TTSI purchased and leased 108 clean diesel trucks, leading the way to transform it's entire fleet to sustainable technology.

Clean Diesel Benefits


Extremely powerful with significantly fewer emissions than standard diesel trucks.
