Abstract:California, given its status as the largest gateway for international trade and domestic commerce in the nation, has identified the need to reduce the negative impacts of freight activity, especially near ports, railroads, highways, and other key facilities. One key geographic area in need of improvements is the South Coast Basin, which is in chronic non-attainment for air quality thresholds. As part of a comprehensive approach, the State has initiated demonstration projects to improve short-haul trucking at maritime Ports, and evaluate alternative fuels for drayage trucks. The purpose of this paper is to: one, examine the results from a pilot of electric drayage trucks at the Port of Los Angeles using secondary and publically reported data; and two, to assess emissions reductions with increased electrification of port truck operations through the implementation of potential drayage policies. The analyses indicate that zero emission drayage vehicles do not provide emissions reductions unless they make significant penetration into the fleet and, even then, the reduction in emissions is largely speculative given uncertainty in electricity emissions intensity.
