On Monday, Southern California Gas Company (SoCalGas) released a report examining the critical role that ultra-low-emission heavy duty natural gas engines can play in helping California achieve its air quality, climate protection and petroleum-displacement goals. The Pathways to Near-Zero-Emission Natural Gas Heavy Duty Vehicles report, authored by Gladstein Neandross & Associates (GNA) on behalf of SoCalGas, showcases the technologies currently under development that could help California meet its near and long term goals. Specifically, the report identifies near-zero-emission, natural gas-fueled heavy duty vehicles as a key strategy that can significantly enhance California’s efforts. The report also calls on California policy makers to enact policies and programs to encourage the development and commercialization of these ultra-low-emission motor vehicle technologies, which will accelerate replacement of the existing diesel-fueled heavy- duty vehicle fleet. “In order to meet stringent air quality targets, regulators can expand the menu of options available to the market,” said Cliff Gladstein, President of GNA and one of the authors of the report. “Heavy-duty natural gas engines are on a trajectory to achieve ultra-low-emission levels that will provide air quality planners with a crucial tool in their efforts to restore clean air to California sooner.” Cliff presented key findings and recommendations outlined in the report on Monday at the Los Angeles-
based VerdeExchange Conference at the L.A. Hotel Downtown. A full copy of the report is available here.
