This report uses real-world observed trucking telematics data from Geotab to investigate which trucks in California and New York can electrify the fastest based on currently available electric truck models. The report also examines the amount of energy and charging infrastructure that these early electrifiable trucks need, in addition to emissions from the grid under various charging schedules. Regardless of when charging occurs, emissions per mile are less than half (and in some cases less than 10 percent) of those from diesel trucks. California and New York house approximately 14 percent of the truck population in the United States. In the next iteration of this project, the authors will perform a similar analysis for all 15 states that are following California’s lead.
