CARBON AWARE RESOURCES

BEST Framework

The BEST (Bus Electrification for School Transportation) framework allows for easy comparison of electric school buses and fossil fuel buses. It automatically produces graphical charts of Total Cost of Ownership and Cumulative Carbon Savings. It also serves as a repository of resources to convince School officials, transportation staff and the voting public about the benefits of electric school buses in a quantified manner.
