RFP 24RD004 Tracking Light-Duty Vehicle Emission Characteristics Using a Remote Sensing Device at Two California Locations

Under State legislative directions, the California Air Resources Board (CARB) has been developing and implementing comprehensive programs to reduce tailpipe emissions from light-duty vehicles (LDV) with internal combustion engine (ICE), to foster electric vehicle (EV) transition, and to address community-level air pollution disparities from environmental justice perspectives.

Through research projects sponsored by CARB and partner organizations such as the Coordinating Research Council (CRC) and Bureau of Automotive Repair (BAR), CARB has collected vehicle exhaust emission data measured with roadside-deployed remote sensing device (RSD) at a historical West Los Angeles location and at a number of other locations across the State. These measurements established longitudinal trends of LDV fleet emission characteristics and a snapshot assessment of statewide emission rate disparities between vehicles registered in socioeconomically disadvantaged communities (DAC) and non-DAC-registered vehicles. This project will extend the longitudinal fleet emission characteristics trends and the DAC/non-DAC vehicle emissions disparities.

The Contractor will use a roadside-deployed remote sensing device (RSD) to measure tailpipe carbon monoxide (CO), hydrocarbon (HC), nitrogen oxides (NOX), and ammonia (NH3) emission rates from light-duty vehicles (LDV) at a historical West Los Angeles measurement location and another RSD measurement location to be determined during the project. The Contractor will use the newly collected data and historical data collected through previous RSD measurement studies to assess longitudinal trends of LDV fleet emission characteristics and analyze emission rate disparities between vehicles registered in socioeconomically disadvantaged communities (DAC) and non-DAC-registered vehicles.
