Delivery FLEET 1.0 is intended as a guide for understanding the potential benefits and operational considerations of adopting zero-emission vehicles for first/last-mile delivery. While the creators have made every effort to ensure accurate estimates, the results obtained from use of this tool are not guaranteed to be exact. Actual results may vary depending on considerations such as weather, refueling location, fuel-price structure, land-use context, or whether vehicles are owned, leased, or shared. The input data which this calculator uses is based upon a variety of sources. In some instances, assumptions were made regarding input data due to a lack of available data, as some vehicle technology included in this tool is nascent. Version 1.0 of this tool does not include total cost of ownership considerations such as reduced maintenance costs, facility needs, or fees commonly associated with near- and zero-emission vehicle deployment (such as demand charges).

A full description of the methods used to build this tool, as well as assumptions, sources, and references, is available in the accompanying white paper, “Delivery First/Last-Mile Emissions Estimation Tool (FLEET) Vehicle Analysis.”

We welcome your comments and suggestions. If you have feedback for improving the tool or making the data it uses more accurate, please contact the creators at deliveryfleet@calstart.org.

Delivery FLEET is based the best available data and may not accurately reflect the most recent model offerings. We would greatly appreciate your assistance in making this tool more comprehensive, accurate, and robust.  If you manufacture last-mile delivery vehicles class 4 or smaller that are not yet in Delivery FLEET, please complete this form in order to update current listings and add new vehicles.
