Title:

Pathways to Clean Vehicles and Fuels in San Bernardino County, California

Abstract:

San Bernardino County, California, faces urgent challenges associated with air quality and climate change. Public agencies have established aggressive goals to reduce nitrogen oxide (NOx) and greenhouse gas (GHG) emissions from on-road vehicles. With a variety of vehicle technology and fuel options available to reduce emissions and their different benefits and costs, government agencies need more information to support a transition to cleaner vehicles and fuels. This analysis was intended to help these agencies with their decision making. The paper describes the development and application of an analysis tool for the purpose of quantifying the emissions and cost impacts of alternative paths to clean vehicle and fuels implementation. Five scenarios are analyzed and compared to a baseline scenario through 2040. None of the scenarios achieve the NOx and GHG emission reduction targets for 2030 that are consistent with state and regional goals, highlighting the challenging nature of those targets. Scenarios involving accelerated introduction of electric vehicles and, for medium and heavy-duty vehicles, natural gas vehicles can both achieve large NOx and GHG reductions at similar net costs. A more aggressive electrification scenario can achieve 2040 GHG emissions reductions commensurate with state goals. A scenario involving greater use and lower carbon intensity of liquid biofuels, coupled with the introduction of low-NOx diesel engine technology, can also achieve significant NOx and GHG emission reductions. However, unlike electrification and natural gas scenarios, this scenario does not result in net cost savings because it would not reduce vehicle operating costs.
