In the lead-up to Clean Air Day 2019, heavy-duty trucking company Total Transportation Services Inc. (TTSI) will announce its switch from all diesel vehicles to 100% clean natural gas, battery electric and hydrogen fuel cell vehicles. The company is partnering with Cummins Westport, Clean Energy, SoCalGas and the Coalition for Clean Air to raise awareness of the importance of renewable natural gas and hydrogen trucking in Los Angeles, Long Beach, and the surrounding regions.

In any given month, 13,000 to 14,000 trucks call at the Ports of Long Beach and Los Angeles, emitting roughly 2,600 tons per year of smog-causing nitrogen-oxide emissions.


To combat such emissions as part of its commitment to clean air, TTSI purchased 40 natural gas near-zero emission heavy-duty trucks this month, far more than any other trucking company that serves the L.A./Long Beach ports. In addition, the trucks will be fueled with carbon-negative renewable natural gas rather than “fossil” gas. If near-zero and zero-emissions trucks become the standard, there would be an overall 90% reduction in smog-forming emissions, which would have a major impact on air quality in the region, and in turn help significantly in meeting Federal ozone standards to avoid Clean Air Act sanctions.
