September 27, 2019. Total Transportation Services (TTSI) is replacing its entire diesel trucking fleet with near-zero emission (NZE) natural gas trucks. These trucks will be fueled with carbon negative renewable natural gas (RNG). The company is also testing a number of Zero-Emission (ZE) Trucks and solutions.

Carbon negative means that trucks reduce their carbon footprint to less than neutral, having a net effect of removing carbon dioxide from the atmosphere rather than adding it.

The announcement was made in conjunction with the non-profit Coalition for Clean Air (CCA) to raise awareness of the importance of natural and renewable gas trucking to help improve air quality and reduce greenhouse gas emissions in the Los Angeles region, especially at the L.A. and Long Beach ports.

Southern California Gas Co. (SoCalGas), along with environmental health non-profit BREATHE LA, fueling company Clean Energy, engine manufacturer Cummins Westport, and the California Air Resources Board (CARB) participated in today’s announcement. Twenty-five percent of TTSI’s investment in the new natural gas trucks was funded through CARB’s California Climate Investments initiative, a statewide program that puts billions of cap-and-trade dollars to work reducing greenhouse gas emissions, strengthening the economy and improving public health and the environment—particularly in disadvantaged communities.

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. TTSI’s 40 new near-zero emission (NZE) heavy-duty compressed natural gas (CNG) trucks reduce this type of emissions by 90 percent in comparison with their diesel counterparts. In addition, when fueled with renewable natural gas the trucks will reduce greenhouse gas emissions by more than 80 percent.
