California targets diesel emissions from heavy-duty trucks

  • 15-Dec-2008 03:21 EST

CARB (California Air Resources Board) on Dec. 12 adopted several measures designed to reduce emissions from heavy-duty diesel-powered trucks. The measures are contained in two sets of rules. The Statewide Truck and Bus rule will require owners of in-use heavy-duty diesel trucks to install exhaust filters under a phase-in schedule that calls for 100% compliance by 2014. That same rule will require owners to replace engines older than the 2010 model year under a staggered schedule that extends from 2012 to 2022. Under the Heavy-Duty Vehicle Greenhouse Gas Emission Reduction measure, long-haul truckers must install fuel-efficient tires and aerodynamic devices on most types of tractors and trailers.
